Seretonin (5HT) and Its Antagonists PharmacologyPranatiChavan
Serotonin is a chemical that has a wide variety of functions in the human body. It is sometimes called the happy chemical, because it contributes to wellbeing and happiness.
The scientific name for serotonin is 5-hydroxytryptamine, or 5-HT. It is mainly found in the brain, bowels, and blood platelets.
Serotonin is used to transmit messages between nerve cells, it is thought to be active in constricting smooth muscles, and it contributes to wellbeing and happiness, among other things. As the precursor for melatonin, it helps regulate the body’s sleep-wake cycles and the internal clock.
It is thought to play a role in appetite, the emotions, and motor, cognitive, and autonomic functions. However, it is not known exactly if serotonin affects these directly, or if it has an overall role in co-ordinating the nervous system.

Epidemiology is the study of occurrence, distribution and determinants of health and
diseases or disorders in man and its application in controlling health problems.
Epidemiology has by tradition two major areas.
First is the study of infectious diseases that spread to large populations, i.e., epidemics.
The second is the study of chronic diseases.
Epidemiological studies help to solve such health problems and provide a basis for
improving living conditions of the people.
During its progress and development, epidemiology has made available precise and
strict methodologies for the study of diseases.
Pharmacology is the study of the effects of drugs.
Clinical Pharmacology is the study of the effects of drugs in humans, It is traditionally
divided into two basic areas namely:
1. Pharmacokinetics
2. Pharmacodynamics.
Pharmacokinetics is the study of the relationship between dose administered of a drug
and the serum or blood level achieved, it deals with absorption, distribution, metabolism
and excretion.
Epidemiology is the study of the distribution and determinants of diseases in
populations.
Epidemics is the study of chronic/ infectious diseases in large populations.
Pharmacoepidemiology is the study of the use of and the effects of drugs in large
number of people.
It involves the examination of a single individual or large groups of people followed for
many years.
It involves gathering & analysis of information in order to identify possible causation &
related factors, that can be applied in clinical practice to group of people & also to
individuals undergoing treatment.

Patient compliance: Challenges in management of cardiac diseases in Kuala Lum...pharmaindexing
Background
The objective of this study was to investigate the degree of compliance among cardiac patients who attend the health facilities in Kuala Lumpur and Perak, Malaysia. The reasons for non-compliance and recommendations from healthcare professionals were also evaluated.
Method
A cross-sectional study of 400 patients and 100 healthcare professionals was carried out. This study utilizes variables on external factors and internal factors as the measurement tools. The questionnaire which consists of Morisky self-reported medication adherence questions was administered to patients and causes for non-compliance sought. Questionnaire for healthcare professionals was used to determine strategies that can improve compliance rate.
Results
The study revealed a 15.8% of high adherence rate, 54.3% of moderate adherence rate and 30% of poor adherence to cardiovascular disease medications. The chi-square tests showed the strong association between dependent and independent variables. The model chosen for testing the patient compliance through external and internal factors gives an R2 value of 85.0% with an adjusted R2 of 84.7%. The F value (317.187) was also significant (p=0.000) which means that the variables have better fit in the multivariate model. The major reasons determined for non-adherence were attitudes and beliefs, lifestyle, side effects and cost of medications. The study recommends that pharmacists and dispensing technicians should be adequately qualified to provide proper counselling to cardiac patients on their medicines and disease conditions.
Conclusion
The result of this study is of value to health care providers. Compliance to cardiovascular medications will avoid treatment failures encountered in therapy.

Adverse Drug Reactions Risk Factors, Epidemiology, and Management Strategiesijtsrd
Objectives The objective of this article is to review the impact of various factors on the occurrence of Adverse Drug Reactions ADRs . Summary ADRs can be caused by several factors, including patient related, drug related, and social factors. Age is a crucial factor in the occurrence of ADRs, with both very young and very old patients being more vulnerable than other age groups. Alcohol consumption also plays a significant role in ADRs. Other factors that affect ADRs include gender, race, pregnancy, breastfeeding, kidney problems, liver function, drug dose and frequency, and many others. The medical literature has extensively documented the impact of these factors on ADRs. Taking these factors into account during medical evaluation enables healthcare professionals to choose the most appropriate medication regimen for their patients. Conclusion Various factors affect the occurrence of ADRs, some of which can be changed such as smoking or alcohol consumption while others cannot be changed such as age or genetic factors . Understanding the impact of these factors on ADRs can help healthcare professionals to select the best medication for their patients and provide them with appropriate advice. Pharmacogenomics, a new and innovative science, emphasizes the genetic predisposition of ADRs, providing a new perspective in the drug selection decision making process. B.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.

ABSTRACT
Objectives
Our objectives are to evaluate prescription pattern and rational use of statins in a tertiary care corporate hospital.
Methodology
It was a prospective observational study conducted for a period of 6 months and included various departments of 300
bedded multi specialty tertiary care corporate hospital. A total of 200 patients were included and the study criteria
was inpatients and induvial more than 18 years of either gender who are prescribed with HMG-CoA reductase
inhibitors.
Results
In the present study 200 patients belonged to the age group of above 18 years, out of which about 65% were male
and 35% were female. Atorvastatin (67%) was prescribed mostly and Rosuvastatin (29.5%) was also used.
Conclusion
It is finally concluded that Rational and prophylactic use of statins can reduce further complications of Diabetes
Mellitus (DM) and cardiac events.
Statins treatment is favourable in long term treatment of diseases, it is most effectively used in treatment of serious
disease conditions which has shown its immense therapeutic role in treatment.

INTRODUCTION
Medicines are an integral part of the health care,
and modern health care is impossible without the
availability of necessary medicines. They not only
save lives and promote health, but prevent
epidemics and diseases too. Accessibility to
medicines is the fundamental right of every person.
However, to bring optimal benefit, they should be
safe, efficacious, cost-effective and rational
Prescription pattern and rational use
Prescription pattern monitoring studies (PPMS)
are a tool for assessing the prescribing, dispensing
and distribution of medicines. Prescription pattern

explain the extent and profile of drug use, trend,
quality of drugs and compliance with regional, state
or national guidelines like standard treatment
guidelines, usage of drugs from essential medicine
list and use of generic drugs. The main aim of
PPMS is to facilitate rational use of medicines
(RUM). There is paucity of published data
analyzing the effectiveness of PPMS. The present
review has been done to assess the effectiveness of
prescription pattern monitoring studies in
promoting RUM. Data search was conducted on
internet. A multitude of PPMS done on different
classes of drugs were collected and analyzed.
PPMS using American College of Cardiology-
American Heart Association (ACC-AHA)
guidelines 2013 and recommendations from
National Lipid Association (NLA) were included. It
was observed in the majority of such studies that
physicians do not adhere to the guidelines made by
regulatory agencies leading to irrational use of
medicines. This in turn leads to increased incidence
of treatment failure, antimicrobial resistance and
economic burden on the patient and the community
as a whole. The treatment of diseases by the use of
essential drugs, prescribed by their generic names,
has been emphasized by the World Health
Organization (WHO) and the National Health
Policy of India. The prescription monitoring studies
provide a bridge between areas like rational use of
drugs, pharmacovigilance, and evidence based
medicine, pharmacoeconomics. In India, this is the
need of the hour to utilize the data generated by so
many prescription pattern monitoring studies done
in every state and on every drug, so that the main
aim of promoting rational use of drugs is fulfilled
[1].
The prevalence of Cardiovascular Diseases
(CVD) is increasing in India. As per an estimate by
Public Health Foundation of India, in 2011; there
were 30 million patients with Chronic Heart
Disease (CHD), in India. The prevalence of
paralytic stroke is between 334 and 424 per
100,000 in urban areas and between 244 and 262
per 100,000 in rural areas. The mortality due to
CVD is projected to rise to 4.2 million by 2030[8].
The aim of PPMS is to facilitate the rational use
of drugs in a population. Irrational use of medicines
is a major problem worldwide. WHO estimates that
more than half of all medicines are prescribed,
dispensed or sold inappropriately, and that half of
all patients fail to take them correctly. The overuse,
underuse or misuse of medicines results in wastage
of scarce resources and widespread health hazards.
The rational use of medicines (RUM) is defined as
“Patients receive medications appropriate to their
clinical needs, in doses that meet their own
individual requirements, for an adequate period of
time, and at the lowest cost to them and their
community [1].
A large number of studies have been conducted
to study the prescribing pattern of physicians across
the country. The studies conclude the irrational
prescribing practices of prescribers and suggest
RUM at all levels of health care delivery system.
However, no systematic reviews, meta-analyses, or
randomized controlled trials are present about the
relevance of PPMS in promoting rational use of
drugs. The present review has been done to assess
the effectiveness of PPMS in developing RUM.
This study was conducted with the aim of
analyzing the prescribing practices of physicians
and to assess the extent to which the goal of RUM
has been achieved. The drugs frequently prescribed
by the physicians for disease conditions like
diabetes, hypertension, coronary artery disease
have been included in this study. An effort has been
made to also include the prescribing trends of
antiplatelet drugs due to the increased incidence of
cardiovascular diseases [1, 2].
The higher incidence of chronic diseases
and degenerative pathologies increases demand
for prescription medicines to treat these conditions,
and to provide quality of life and well‐ being,
which renders older susceptible to the risk of
polypharmacy and drug‐ related illnesses. Aging
related pathophysiologic changes also make them
more prone to medication error. The resulting
altered pharmacokinetics and pharmacodynamics
due to these changes, makes them more
susceptible to the adverse effects of drugs. Gaining
insight into physicians prescribing pattern in
order to identify prescribing problem is the
fundamental step in improving the quality of
prescription and patient care. This study gives
an insight into the prevalence of prescribing
error in one of the territory care corporate
hospital with an aim to determine the nature and
types of medication prescribing errors in territory
care corporate hospital setting together with the
pattern of drug use in elderly [2].

Initiation of statin therapy
Cardiovascular disease (CVD) is the leading
cause of death worldwide. Many prospective cohort
studies have shown that high levels of low-density
lipoprotein cholesterol (LDL-c) are a major risk
factor for CVD. 3-Hydroxy 3-methylglutaryl
coenzyme A (HMG-CoA) reductase inhibitors
(statins) reduce all-cause mortality and major
vascular events by approximately 23% for each
1.0 mmol/l lowering of LDL-c. The challenge of
statin treatment is the identification of patients who
would benefit from treatment. Various guidelines
have been developed to guide physicians.
In the Randomized Control Trials (RCTs)
reviewed, initiation of moderate-intensity therapy
(lowering LDL-C by approximately 30% to <50%)
or high-intensity statin therapy (lowering LDL-C
by approximately ≥50%) is a critical factor in
reducing Atherosclerotic Cardiovascular disease
(ASCVD) events. Moreover, statin therapy reduces
ASCVD events across the spectrum of baseline
LDL-C levels ≥70 mg/dL. In addition, the relative
reduction in ASCVD risk is consistent for primary
and secondary prevention and for various patient
subgroups [3].
On the basis of this large and consistent body of
evidence, 4 major statin benefit groups were
identified for whom the ASCVD risk reduction
clearly outweighs the risk of adverse events based
on a strong body of evidence.
These are:
1) Secondary prevention in individuals
with clinical ASCVD,
2) Primary prevention in individuals with primary
elevations of LDL-C ≥190 mg/dL,
3) Primary prevention in individuals with diabetes
40 to 75 years of age who have LDL-C 70 to 189
mg/dL, and
4) Primary prevention in individuals without
diabetes and with estimated 10-year ASCVD
risk ≥7.5%, 40 to 75 years of age who have LDL-
C 70 to 189 mg/dL.
Moderate evidence supports the use of statins
for primary prevention in individuals with 5%
to <7.5% 10-year ASCVD risk, 40 to 75 years of
age with LDL-C 70 to 189 mg/dL. Selected
individuals with <5% 10-year ASCVD risk, or <40
or >75 years of age may also benefit from statin
therapy. Clinicians and patients should engage in a
discussion of the potential for ASCVD risk-
reduction benefits, adverse effects, drug–drug
interactions, and consider patient preferences for
treatment. It also emphasize healthy-lifestyle habits
and addressing other risk factors [3].
Intensity of statin therapy in primary and
secondary prevention:
The Expert Panel defined the intensity of statin
therapy on the basis of the average expected LDL-
C response to a specific statin and dose. “High-
intensity,” “moderate-intensity,” and “low-
intensity” statin therapy definitions were derived
from the systematic reviews. The basis for
differentiation among specific statins and doses
arose from the RCTs, where there was a high level
of evidence that high-intensity statin therapy with
atorvastatin 40 mg to 80 mg reduced ASCVD risk
more than moderate-intensity statin therapy with
atorvastatin 10 mg, pravastatin 40 mg, or
simvastatin 20 mg to 40 mg twice daily [3].
High-Intensity Statin Therapy Moderate-Intensity Statin Therapy Low-Intensity Statin

Women and men with clinical ASCVD (acute
coronary syndromes; history of MI, stable or
unstable angina) arterial revascularization, stroke,
transient ischemic attack, or peripheral arterial
disease presumed to be of atherosclerotic origin are
at increased risk for recurrent ASCVD and ASCVD
death. An extensive body of evidence demonstrates
that high-intensity statin therapy reduces ASCVD
events more than moderate-intensity statin therapy
in individuals with clinical ASCVD.
High-intensity statin therapy should be initiated
for adults ≤75 years of age with clinical ASCVD
who are not receiving statin therapy, or the
intensity should be increased in those receiving a
low- or moderate-intensity statin, unless they have
a history of intolerance to high-intensity statin
therapy or other characteristics that could influence
safety. The high-intensity statins atorvastatin 80 mg
and Rosuvastatin 20 mg daily reduce LDL-C ≥50%
on average and have been shown to reduce ASCVD
events in RCTs [3].
Stratifying by the type of prevention,
atorvastatin was significantly more prescribed for
secondary prevention than for primary. A recent
meta-analysis on comparative benefits of statins on
major cerebrovascular events suggested that,
although any statin therapy is associated with a
significant reduction in cerebrovascular events in
secondary prevention, only atorvastatin resulted in
significantly fewer events than controls [5].
Primary prevention in individuals with
diabetes
A high level of evidence supports the use of
moderate-intensity statin therapy in persons with
diabetes who are 40 to 75 years of age. The only
trial of high-intensity statin therapy in primary
prevention was performed in a population without
diabetes. However, a high level of evidence existed
for event reduction with statin therapy in
individuals with a ≥7.5% estimated 10-year
ASCVD risk who did not have diabetes to
recommend high-intensity statin therapy
preferentially for individuals with diabetes and
a ≥7.5% estimated 10-year ASCVD risk .This
consideration for those with diabetes who are 40 to
75 years of age recognizes that these individuals
are at substantially increased lifetime risk for
ASCVD events and death. Moreover, individuals
with diabetes experience greater morbidity and
worse survival after the onset of clinical ASCVD.
In persons with diabetes who are <40 years of age
or >75 years of age, or whose LDL-C is <70
mg/dL, statin therapy should be individualized on
the basis of considerations of ASCVD risk-
reduction benefits, the potential for adverse effects
and drug–drug interactions, and patient
preferences[4].
2014 nla criteria for treatment initiation
according to risk:
Clinicians have felt somewhat lost with the
current ACC/AHA guidelines.
In 2014, the National Lipid Association (NLA)
published recommendations for identifying
patients by risk-
Moderate, high, or very high risk

risk categories. [11]

2016 consensus statement from ACC/AHA
and NLA
In 2016, a consensus guideline on the
management of atherosclerotic cardiovascular
disease (ASCVD) risk was published by the
ACC/AHA and NLA
Includes the same treatment recommendations
Provides guidance for treatment after statin use or
in cases of statin-intolerance. [3, 11]
Rationale for the expert panel approach to
primary –prevention guidelines
1. Cholesterol-lowering medications, particularly
statins, are efficacious and effective for reducing
risk of initial cardiovascular events.
2. Statins are associated with similar relative risk
reductions for cardiovascular events across the
majority of primary-prevention patient groups
studied.
3. The extent of relative risk reduction for ASCVD
is proportional to the degree of LDL-C lowering
observed on statin therapy. Therefore, more
intensive statin therapy could reduce risk more
than moderate- or lower-intensity statin therapy.
4. According to consistent findings,
the absolute benefit in ASCVD risk reduction is
proportional to the baseline risk of the patient

group or individual and to the intensity of statin
therapy.
5. Patients or groups at higher
baseline absolute risk, therefore, will derive
greater absolute benefit from initiation of statin
therapy over a period of 5 to 10 years.
6. The absolute risk for adverse outcomes, including
a small excess in cases of newly diagnosed
diabetes, also appears to be proportional to the
intensity of statin therapy. However, the adverse
outcome of incident (or earlier diagnosis of)
diabetes must be weighed in the context of the
potentially fatal or debilitating occurrence of MI
or stroke that could be prevented by statin
therapy.
7. The Expert Panel emphasizes that the occurrence
of a major ASCVD event (MI or stroke)
represents a much greater harm to health status
than does an increase in blood glucose leading to
a diagnosis of diabetes. The net absolute
benefit of statin therapy can be considered as a
comparison of the absolute risk reduction for
ASCVD with the absolute excess risks, including
that for diabetes. Benefit also could be
understood as a comparison of the number of
statin-treated patients that would result in the
prevention of 1 case of major ASCVD with the
number of statin-treated patients that would result
in 1 excess case of diabetes.
8. Because the absolute benefit in terms of ASCVD
risk reduction depends on the
baseline absolute risk for ASCVD, the absolute
benefit from initiation of statin therapy is lower
and would approach the risk for adverse effects in
patients with lower baseline levels of predicted
ASCVD risk.
9. Available RCT evidence indicates a clear net
absolute benefit of initiation of moderate-to-
intensive statin therapy at a baseline estimated
10-year ASCVD risk of ≥7.5%.
10. Available RCT evidence indicates that when
baseline ASCVD risk is 5.0% to <7.5%, there is
still net absolute benefit with moderate-intensity
statin therapy. However, the tradeoffs between
the ASCVD risk-reduction benefit and adverse
effects are less clear. Thus, a clinician-patient
discussion is even more important for individuals
with this range of ASCVD risk. The net benefit
of high-intensity statin therapy may be marginal
in such individuals [3]
.
This guideline recommends that initiation of
moderate-intensity statin therapy be considered for
patients with predicted 10-year “hard” ASCVD risk
of 5.0% to <7.5%.
A conservative estimate of adverse events
includes excess cases of new-onset diabetes and
rare cases of myopathy and hemorrhagic stroke.
The rate of excess diabetes varies by statin
intensity. For moderate-intensity statins,
approximately 0.1 excess case of diabetes per 100
statin-treated individuals per year has been
observed, and for high-intensity statins,
approximately 0.3 excess case of diabetes per 100
statin-treated individuals per year has been
observed. The long-term adverse effects of statin-
associated cases of diabetes over a 10-year period
are unclear and are unlikely to be equivalent to an
MI, stroke, or ASCVD death. Myopathy (∼0.01
excess case per 100) and hemorrhagic stroke
(∼0.01 excess case per 100) make minimal
contributions to excess risk from statin therapy [3].
Statin safety recommendation:
To maximize the safety of statins, selection of
the appropriate statin and dose in men and non
pregnant/ nonnursing women should be based on
patient characteristics, level of ASCVD risk, and
potential for adverse effects. Moderate-intensity
statin therapy should be used in individuals in
whom high-intensity statin therapy would
otherwise be recommended when characteristics
predisposing them to statin–associated adverse
effects are present.
Characteristics predisposing individuals to
statin adverse effects include but are not
limited to:
Multiple or serious co morbidities, including
impaired renal or hepatic function.
History of previous statin intolerance or muscle
disorders.
Unexplained ALT elevations ≥3 times.
Patient characteristics or concomitant use of
drugs affecting statin metabolism.
Age >75 years.
Additional characteristics that could modify the
decision to use higher statin intensities might
include but are not limited to:
History of hemorrhagic stroke.
Asian ancestry.

For individuals presenting with a confusional
state or memory impairment while on statin
therapy, it may be reasonable to evaluate the
patient for nonstatin causes, such as exposure to
other drugs, as well as for systemic and
neuropsychiatric causes, in addition to the
possibility of adverse effects associated with statin
drug therapy.
It is reasonable to evaluate and treat muscle
symptoms, including pain, tenderness, stiffness,
cramping, weakness, or fatigue, in statin-treated
patients according to the following management
algorithm:
To avoid unnecessary discontinuation of
statins, obtain a history of prior or current
muscle symptoms to establish a baseline before
initiation of statin therapy.
If unexplained severe muscle symptoms or
fatigue develop during statin therapy, promptly
discontinue the statin and address the possibility
of rhabdomyolysis by evaluating Creatinine
kinase (CK) and creatinine and performing
urinalysis for myoglobinuria.
If mild to moderate muscle symptoms develop
during statin therapy:
– Discontinue the statin until the symptoms can be
evaluated.
– Evaluate the patient for other conditions that
might increase the risk for muscle symptoms
(e.g., hypothyroidism, reduced renal or hepatic
function, rheumatologic disorders such as
polymyalgia rheumatica, steroid myopathy,
vitamin D deficiency, or primary muscle
diseases).
– If muscle symptoms resolve, and if no
contraindication exists, give the patient the
original or a lower dose of the same statin to
establish a causal relationship between the
muscle symptoms and statin therapy.
Individuals receiving statin therapy should be
evaluated for new-onset diabetes according to the
current diabetes screening guidelines. Those who
develop diabetes during statin therapy should be
encouraged to adhere to a heart-healthy dietary
pattern, engage in physical activity, achieve and
maintain a healthy body weight, cease tobacco use,
and continue statin therapy to reduce their risk of
ASCVD events.
Decreasing the statin dose may be considered when
2 consecutive values of LDL-C are <40 mg/dL. This
recommendation was based on the approach taken in
2 RCTs. However, no data were identified that
suggest an excess of adverse events occurred when
LDL-C levels were below this level [3].
Recommendations for monitoring, optimizing
and addressing insufficient response to statin
therapy
Monitoring statin therapy
Adherence to medication and lifestyle,
therapeutic response to statin therapy, and safety
should be regularly assessed. This should also
include a fasting lipid panel performed within 4–12
weeks after initiation or dose adjustment, and every
3–12 months thereafter. Other safety measurements
should be measured as clinically indicated.
Optimizing statin therapy
The maximum tolerated intensity of statin
should be used in individuals for whom a high- or
moderate-intensity statin is recommended but not
tolerated.
Insufficient Response to Statin Therapy
In individuals who have a less-than-anticipated
therapeutic response or are intolerant of the
recommended intensity of statin therapy, the
following should be performed:
Reinforce medication adherence.
Reinforce adherence to intensive lifestyle
changes.
Exclude secondary causes of hyperlipidemia [3].
Factors affecting statins prescribing pattern
Lack of familiarity with the current clinical
guidelines.
Speciality of the prescriber.
Lack of proper outcome anticipation.
Practice setting related limitations.
Patient related limitations.
Presence of guidelines, concerns or disagreement
[6].
Factors affecting patients compliance to statin
therapy
Patient related factors

Rationale
Importance
Cardiovascular disease is a broad term that
encompasses a number of atherosclerotic
conditions that affect the heart and blood vessels,
including coronary heart disease, as ultimately
manifested by myocardial infarction (MI), and
cerebrovascular disease, as ultimately manifested
by stroke. Cardiovascular disease is the leading
cause of morbidity and mortality in the United
States, accounting for 1 of every 3 deaths among
adults.
Statins are a class of lipid-lowering medications
that function by inhibiting the enzyme (HMG-Co-
A) 3-hydroxy-3-methyl-glutaryl coenzyme A
reductase, which is involved in the rate-limiting
step in the production of cholesterol. Statins reduce
levels of total cholesterol and LDL-C and, to a
lesser extent, triglycerides, and probably have anti-
inflammatory and plaque stabilization effects as
well [7].
Potential Benefits of Statin Use
The US Preventive Services Task Force
(USPSTF) found adequate evidence that use of
low- to moderate-dose statins reduces the
probability of CVD events (MI or ischemic stroke)
and mortality by at least a moderate amount in
adults aged 40 to 75 years who have 1 or more
CVD risk factors (dyslipidemia, diabetes,
hypertension, or smoking) and a calculated 10-year
CVD event risk of 10% or greater.
The USPSTF found adequate evidence that use
of low- to moderate-dose statins reduces the
probability of CVD events and mortality by at least
a small amount in adults aged 40 to 75 years who
have 1 or more CVD risk factors (dyslipidemia,
diabetes, hypertension, or smoking) and a
calculated 10-year CVD event risk of 7.5% to 10%.
The USPSTF found inadequate evidence to
conclude whether initiating statin use in adults 76
years and older who are not already taking a statin
is beneficial in reducing the incidence of CVD
events and mortality [7].
Potential Harms of Statin Use
The USPSTF found adequate evidence that the
harms of low- to moderate-dose statin use in adults
aged 40 to 75 years are small. Randomized clinical
trials (RCTs) of statin use for the primary
prevention of CVD events have largely used low
and moderate doses; under these conditions, statin
use was not associated with serious adverse events
such as cancer, severely elevated liver enzyme
levels, or severe muscle-related harms. However,
evidence concerning the association between statin
use and diabetes mellitus is mixed, with 1
prevention trial suggesting that there may be a
small increased risk of developing diabetes with
use of high-dose statins. Myalgia is a commonly
reported adverse effect of statins, but placebo-
controlled trial data do not support the conclusion
that statin use has a major causative role in its
occurrence. Evidence for cognitive harms is
relatively sparse; further research would be needed
to more definitively establish the relationship
between statin use and cognitive function. The
USPSTF found no clear evidence of decreased
cognitive function associated with statin use. These
findings are consistent with those from a recent
systematic review of RCTs and observational
studies assessing the effect of statins on cognition
that found no effect on incidence of Alzheimer
disease or dementia. The recently published HOPE-
3 (Heart Outcomes Prevention Evaluation 3) trial
found that statin use increased risk of cataract
surgery, which was unanticipated and not a
predetermined outcome of the trial. None of the
other primary prevention trials reported this
outcome.
The USPSTF found inadequate evidence on the
harms of statin use for the prevention of CVD
events in adults 76 years and older without a
history of heart attack or stroke [7].
Pharmacology of statins
Statins are the structural analogues of HMG-
CoA (3-hydroxy-3-methylglutaryl-coenzyme A).
Introduced in 1980‟s this class of compounds are
9. Praveen K M et al / Int. J. of Pharmacology and Clin. Research Vol-3(1) 2019 [12-30]
20
the most efficacious and best tolerated
hypolipidemic drugs.
Different statins are
Atorvastatin
Rosuvastatin
Lovastatin
Simvastatin
Pravastatin
Pitavastatin
Fluvastatin [9].
Mechanism OF ACTION
They competitively inhibit conversion of 3-
Hydroxy 3-methylglutaryl coenzyme A (HMG-
CoA) to mevalonate (rate limiting step in CH
synthesis) by the enzyme HMG-CoA reductase.
Therapeutic doses reduce CH synthesis by 20-
50%.This results in compensatory increase in LDL
receptor expression on liver cells. Because statins
are similar in structure to HMG-CoA on a
molecular level, they will fit into the enzyme's
active site and compete with the native substrate
(HMG-CoA). This competition reduces the rate by
which HMG-CoA reductase is able to
produce mevalonate, the next molecule in
the cascade that eventually produces cholesterol
[10].
In addition to lowering cholesterol levels,
statins also reduce inflammation, which could be
another mechanism by which statins beneficially
affect atherosclerosis. This reduction of
inflammation does not depend on statins ability to
reduce cholesterol. Furthermore, these anti-
inflammatory effects can be seen as early as two
weeks after starting statins [9, 10].
Other effects include decreased oxidative stress
and vascular inflammation with increased stability
of atherosclerotic lesions. It has become a standard
practice to initiate statins therapy immediately after
acute coronary syndromes, regardless of lipid
levels. Improvement in endothelial function due to
increased NO production and reduction in LDL
oxidation are proposed as additional mechanisms
by which statins may exert anti atherosclerotic
action [9].
Pharmacokinetics
Absorption of ingested doses of the reductase
inhibitors varies from 40%-75% with the
exception of fluvastatin, which is completely
absorbed.
All statins have high first pass extraction by
liver.
Most of the absorbed dose is excreted in the bile;
5-20% is excreted in urine.
Atorvastatin and rosuvastatin has a much longer
plasma half life of 18-24 hours [9].
Adverse effects
All statins are remarkably well tolerated; overall
incidence of adverse effects not differing from
placebo.
Notable adverse effects are- Headache, Nausea,
Bowel upset, Rashes, Sleep disturbances (
probably more with lipophilic drugs)
Rise in serum transaminase can occur, but liver
damage is rare
Muscle tenderness and rise in CPK levels occurs
infrequently. Myopathy is the only serious
reaction, but is rare (<1 per 100). Myopathy is
more common when nicotinic acid/gemfibrozil
or CYP3A4 inhibitor HIV protease inhibitor is
given concurrently [10].
Interactions
May increase risk of myopathy and
rhabdomyolysis with CYP3A4 potent inhibitor
(e.g. HIV or HCV protease inhibitors,
itraconazole, clarithromycin), fenofibrate,
colchicines, and fixed combination of
lopinavir/ritonavir.
May decrease plasma concentration with
CYP3A4 inducer (e.g. rifampicin, efavirenz).
May significantly increase Area under curve
(AUC) and peak plasma concentration of
Digoxin.
Increased AUC for norethindrone and ethinyl
estradiol.
Gemfibrozil inhibits the hepatic uptake of statins
by the organic anion transporter OATP2.
Fenofibrate interferes least with statin uptake/
metabolism and should be preferred for
combining with them. Hence a lower dose of
statin is advised when fibrate is given
concurrently.
Potentially fatal
Increased risk of myopathy or rhabdomyolysis
with ciclosporin, gemfibrozil, telaprevir,
tipranavir.
10. Praveen K M et al / Int. J. of Pharmacology and Clin. Research Vol-3(1) 2019 [12-30]
21
May increase risk of myopathy or
rhabdomyolysis with grapefruit juice [10].
Indications
Statins are the first choice drugs for primary
hyperlipidaemias with raised LDL and total
cholesterol levels, with or without raised TG levels
as well as for secondary (diabetes, nephritic
syndrome) hypercholesterolaemia. Beneficial
effects in subjects who have raised CH levels but
no evidence of CAD may relate to improved
coronary artery compliance and atheromatous
plaque stabilization due to suppression of
macrophage mediated inflammation, reducing
chances of plaque rupture and thrombus formation.
Statins are used in the treatment of
Hyperlipidemia (Primary
hypercholesterolemia and mixed
dyslipidemia)
Indicated as an adjunct to diet for treatment of
elevated total-C, Apo B, and TG levels and to
increase HDL-C in patients with primary
hypercholesterolemia (heterozygous familial and
nonfamilial) and mixed dyslipidemia (Fredrickson
type IIa and IIb).
Hypertriglyceridemia
Adjunct to diet for elevated TG levels
(Fredrickson type IV).
Homozygous familial hypercholesterolemia
Reduction of total-C and LDL-C in Homozygous
familial hypercholesterolemia as an adjunct to
other lip-lowering treatments (eg, LDL apheresis)
or if such treatments are unavailable.
Cardiovascular disease prevention
Reduction of risk of stroke and heart attack in type
2 diabetes patients without evidence of heart
disease but with other CV risk factors.
Reduction of risk of stroke, heart attack, and
revascularization procedures in patients without
evidence of coronary heart disease (CHD) but
with multiple risk factors other than diabetes (eg,
smoking, HTN, low HDL-C, family history of
early CHD).
Patients with CHD, to reduce risks of MI, stroke,
revascularization procedures, hospitalization for
Congestive heart failure(CHF), and angina[9,10].
Contraindications
Statins are contraindicated in case of
Pregnancy and lactation as there is no data
available regarding their safety.
Active liver disease or unexplained persistent
elevations of serum transaminases.
Concomitant use with cyclosporine, gemfibrozil,
Telaprevir, tipranavir [9, 10].

DISCUSSION
In the present study 200 patients belonged to the
age group of above 18 years, out of which about
65% were male and 35% were female. It shows
that in this study, males were mostly prescribed
with statins shown in Table.no.2 with bar diagram.
The mean± SD value of this distribution was
100±42.42.
This study observe that age distribution to
which statins were mostly prescribed was between
61-70 years i.e., 60 (30%) followed by 51-60 years
i.e., 58(29%), 71-80 years i.e., 44(22%) and 41-50
years i.e., 22(11%) leastly prescribed age group
being 91-100 years is 1(0.5%) shown in Table.no.1
with bar diagram. The mean± SD value of this age
distribution was 25±25.26.
Department wise distribution of this study
population shows that statins were prescribed in
various departments of which cardiology
department being mostly prescribed with statins
i.e., 128 (64%) followed by neurology 27(13.5%),
pulmonology 11(5.50%), general medicine
11(5.50%), vascular surgery 7(3.5%), orthopaedics
5(2.50%) and others including nephrology,
gastroenterology, urology, endocrinology were
shown in the table.no.3 with bar diagram. The
mean± SD value of department wise distribution
was 28.57±44.41.

no of patients belonged to weight interval of 61-70
i.e. 66(33%) followed by 51-60 -53 (26.5) were
shown in the Table.no.4 with bar diagram. The
mean± SD value of weight distribution was found
to be 33.3±24.8.
Out of 200 cases the highest no. of patients
were diagnosed with CAD i.e. 71(35.5%) followed
by MI 20(10.0%) and stroke 20(10.0%) , NSTEMI
07(3.50%),CHF 03(1.50%), Cellulitis 03(1.50%)
,DVT 04(2.00%), LRTI 06(3.00%) and others
include bronchial asthma, osteoarthritis, renal
calculi, encephalopathy, etc were shown in the
Table.no.5 with bar diagram. The mean± SD value
of diagnosis wise distribution was 22.22±27.09.
Out of 200 prescriptions frequently prescribed statin
was Atorvastatin 134(67%) and Rosuvastatin
59(29.5%) where as in 2 patients were switched from
atorvastatin to rosuvastatin (1%) and 1 patients was
switched from rosuvastatin to atorvastatin (0.5%)
were shown in the Table no.6 with bar diagram and
pie chart. During our study we encountered 4
prescriptions with a case of therapeutic duplication in
which atorvastatin and rosuvastatin were prescribed
simultaneously (2%). The mean± SD value of
frequently prescribed was found to be 40±58.004.
Out of 200 cases, a majority of the drugs were
purely prescribed based on the Brand names i.e.,
162 (81%) followed by Generic names ie.,38
(19%).The pattern of prescription in terms of the
generic name was found to be low and should be
encouraged more which was shown in the Table
no.7 with bar diagram. The mean± SD value of
types of prescription was 100±87.681.
Out of 200 cases, it is inferred that Aztor was
commonly prescribed brand of atorvastatin 64
(32%) followed by Rosuvas brand of rosuvastatin
57 (28.5%) and Atorva being 43(21.5%), Storvas
14(7%), Tonact 12(6%), Atocar 2(1%), Remetor
2(1%) and Lipicure 1(0.5%), Rozavel 2(1%),
Rosuvast 1(0.5%) were shown in the Table no.8
with bar diagram and pie chart. The mean± SD
value of brands prescribed was found to be
16.66±23.77.
The prescribing pattern of statins is shown in
the Table, no.9 shows that in Monotherapy the no
of prescriptions are 25 followed by in dual therapy
79 prescriptions were prescribed followed by triple
therapy 70 prescriptions and in poly therapy 26
prescriptions were prescribed and it was shown
with bar diagram from Table.no.9.The mean± SD
value of prescription pattern of statins was found to
be 50±28.53.
Out of 200 patients, 108(54%) patients were
found with no history of statin use. And about 24
(12%) patients were prescribed with statin for 1
year, about 38 (19%) were prescribed with statins
from 1-5 years, about 24(12%) were prescribed
with statins from 6-10 years and 6(3%) patients
were prescribed with statins for more than 10 years
which was shown with bar diagram from
Table.no.10. The mean± SD value of duration of
statin use was 40±39.67.
Out of 200 patients most of the drug
information was given to the patients i.e.
115(57.5%) followed by patient representatives 81
(40.5%) and nurse 4 (2.00%) which was shown
with bar diagram from Table no.11. The mean± SD
value of drug information wise distribution was
found to be 66.66±56.87.
Out of 200 patients Oral hypoglycemic agents
were the mostly prescribed drugs i.e., 113 (32.94%)

28
followed by Anti hypertensive‟s 150(43.73%), Anti
platelets 80 (23.32%) which was shown with bar
diagram from Table no.12. The mean± SD value of
different categories of drugs prescribed to patients
was 114.3±35.01.
Out of 200 prescriptions, majority of statins
prescribed were of high intensity i.e., Atorvastatin
107 and Rosuvastatin 49 followed by moderate
intensity Atorvastatin 28 and Rosuvastatin 12
respectively were shown with bar diagram from
Table.no.13.
Out of 200 patients who were given statins, 149
patients (74.5%) were prescribed rationally while
51 patients (25.5%) were prescribed irrationally
were shown with bar diagram from Table.no.14.
The mean± SD value of Rationality wise
distribution was 100±69.2.
Two dimensional studies were also conducted on
Department, Disease, Drugs and Gender.
Comparision of drugs based on departments
(P<0.001).
Comparision of drugs based on diseases (P=0.3421).
Comparision of drugs based on gender (P<0.0001).
CONCLUSION
Present study was conducted in a tertiary care
corporate hospital located in secunderabad. This
study was aimed at assessing the prescription
pattern of statins and we found that majority of the
people belongs to an age group of between 61-70
(30%). The male patients were 65%and 35% were
female patients and it was found that patients are
mostly suffering from CAD (35.5%).
Atorvastatin (67%) was prescribed mostly and
Rosuvastatin (29.5%) was also used. Brand names
were purely prescribed about 81% where as generic
names were prescribed for around 19%. This
concludes that generic name was found to be low
and should be encouraged more. Aztor (32%) and
Rosuvas (28.5%) are the brands which were mostly
prescribed.
Based on prescription pattern of statins about
39.5% of patients were prescribed with Dual
therapy and Monotherapy (12.5%) was leastly
prescribed through which we conclude that
prophylactic use of statins would have reduced
further cardiac events and complications of the
disease.
Finding of the project indicates a significance
reduction in rational prescribing which include
multiple prescribing.
Assuring the safe medications to the patients,
this study has created awareness among the medical
practitioners on the necessity of the clinical
pharmacist in the institutional healthcare setup to
prevent irrational prescribing and to promote
rational use of drugs.
It is finally concluded that Rational and
prophylactic use of statins can reduce further
complications of Diabetes Mellitus (DM) and
cardiac events.
Physicians and pharmacists should also adopt
interventions that are designed to help patients
remember to keep their clinic appointments and to
take their medications as prescribed by the doctor
and promote rational use of drugs in all the
departments.
