Cough can be classified as acute (<3 weeks), sub-acute (3-8 weeks), or chronic (>8 weeks) based on duration. Treatment involves pharyngeal demulcents, expectorants to enhance mucus clearance, and antitussives to suppress cough. Expectorants include guaiphenesin and mucolytics like bromhexine and carbocisteine. Antitussives include codeine, noscapine, and dextromethorphan. Bronchodilators may be used as adjuvants for cough related to bronchospasm. Common cough formulations contain combinations of expectorants, antitussives, and antihistamines.

this presentation gives the knowledge about the decongestants are a type of medication that can provide short relief for a blocked nose ................
This ppt briefly summaries the major drugs used in the management of respiratory disease and are used in their treatment. We will also have a look at the moa, contraindications, pharmacokinetics of drugs used in their treatment.
Asthma is a chronic inflammatory disorder of the airways that is characterized by increased responsiveness of the tracheobranchial tree to a variety of stimuli resulting in widespread spasmodic narrowing of the air passages which may be relieved spontaneously or by therapy.
Cough is a protective reflex, its purpose being expulsion of respiratory secretions or foreign particles from air passages.
It occurs due to stimulation of mechano or chemoreceptors in throat,
respiratory passages or stretch receptors in the lungs.
Act peripherally in the respiratory tract to reduce tussal impulses.
They aim to control rather than eliminate cough.
Many H-1 anti histamines have been conventionally added to antitussive /expectorant formulations.
Antihistamines afford relief in cough due to their sedative and Anticholinergic actions but lack selectivity for cough centre.
Analeptics stimulate respiration and can have resuscitative value in
Coma or fainting.
They stimulate respiration in sub convulsive doses,
but margin of safety is narrow.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.

Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

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

2. Cough is a protective reflex, its purpose being
expulsion of respiratory secretions or foreign
particles from air passages. It occurs due to
stimulation of mechano- or chemoreceptors in
throat, respiratory passages or stretch receptors in
the lungs.
Cough may be productive or nonproductive
Useless (nonproductive) cough should be suppressed.
Useful (productive) cough serves to drain the airway,
its suppression is not desirable, may even be
harmful, except if the amount of expectoration
achieved is small.
Apart from specific remedies (antibiotics), cough
may be treated as a symptom (nonspecific therapy)
with
3. The most common causes of cough can be
categorized according to the duration of the cough.
Acute cough (<3 weeks): URTIs (especially the
common cold, acute bacterial sinusitis, and
pertussis), pneumonia, pulmonary embolus, and
congestive heart failure.
Sub-acute cough (3-8 weeks): post-infectious
Chronic cough (>8 weeks):
In a smoker :chronic obstructive lung disease or
bronchogenic carcinoma.
In a nonsmoker: postnasal drip (sometimes termed
the upper airway cough syndrome), asthma, and
gastroesophageal reflux.
7. Pharyngeal demulcents sooth the throat and
reduce afferent impulses from the
inflamed/irritated pharyngeal mucosa, thus
provide symptomatic relief in dry cough
arising from throat.
Expectorants (Mucokinetics) are drugs
believed to increase bronchial secretion or
reduce its viscosity, facilitating its removal by
coughing.
8. Sodium and potassium citrate are considered
to increase bronchial secretion by salt action.
Potassium iodide is secreted by bronchial
glands and can irritate the airway mucosa.
Prolonged use can affect thyroid function and
produce iodism. It is not used now.
Guaiphenesin, vasaka, tolu balsum are plant
products which are supposed to enhance
bronchial secretion and mucociliary function
while being secreted by tracheobronchial
glands.
9. Ammonium salts are nauseating—reflexly
increase respiratory secretions.
A variety of expectorant formulations
containing an assortment of the above
ingredients, often in combination with
antitussives/antihistaminic are marketed and
briskly promoted,
The US-FDA has stopped marketing of all
expectorants, except guaiphenesin. Steam
inhalation and proper hydration may be more
helpful in clearing airway mucus.
10. Bromhexine A derivative of the alkaloid vasicine
obtained from Adhatoda vasica (Vasaka), is a
potent mucolytic and mucokinetic capable of
inducing thin copious bronchial secretion
It depolymerises mucopolysaccharides directly as
well as by liberating lysosomal enzymes—
network of fibres in tenacious sputum is broken.
It is particularly useful if mucus plugs are
present.
BROMHEXINE 8 mg tablet, 4 mg/5 ml elixir.
11. Ambroxol A metabolite of bromhexine having
similar mucolytic action, uses and side effects
Dose: 15–30 mg TDS. AMBRIL, AMBROLITE, AMBRODIL,
MUCOLITE 30 mg tab, 30 mg/5 ml liquid, 7.5 mg/ml drops.
Acetylcysteine It opens disulfide bonds in
mucoproteins present in sputum—makes it less
viscid, but has to be administered directly into
the respiratory tract.
Carbocisteine It liquefies viscid sputum in the
same way as acetylcysteine and is administered
orally (250–750 mg TDS). Chronic bronchitis
patients have been shown to benefit. It may
break gastric mucosal barrier; is contraindicated
in peptic ulcer patients
12. These are drugs that act in the CNS to raise
the threshold of cough center or act
peripherally in the respiratory tract to reduce
tussal impulses, or both these actions.
Because they aim to control rather than
eliminate cough, antitussives should be used
only for dry nonproductive cough or if cough
is unduly tiring, disturbs sleep or is
hazardous (hernia, piles, cardiac disease,
ocular surgery)
13. Codeine :An opium alkaloid, qualitatively
similar to and less potent than morphine, but
is more selective for cough center. Codeine is
regarded as the standard antitussive;
suppresses cough for about 6 hours.
Constipation is the chief drawback..
At higher doses respiratory depression and
drowsiness can occur, especially in children.
Driving may be impaired. Like morphine, it is
contraindicated in asthmatics
14. Ethyl morphine It is closely related to codeine
which is methyl morphine, and has
antitussive, respiratory depressant properties
like it, but is believed to be less constipating.
Dose: 10–30 mg TDS; DIONINDON 16 mg tab
15. Noscapine: (Narcotine) An opium alkaloid of
the benzoisoquinoline series (see Ch. 34). It
depresses cough but has no narcotic,
analgesic or dependence inducing properties
It is nearly equipotent antitussive as codeine,
especially useful in spasmodic cough.
Dose: 15–30 mg, children 2–6 years 7.5 mg, 6–12 years 15
mg.
COSCOPIN 7 mg/5 ml syrup, COSCOTABS 25 mg tab.
16. Dextromethorphan :A synthetic central NMDA
(N-methyl D-aspartate) receptor antagonist;
the d-isomer has antitussive action while l-
isomer is analgesic.
Dextromethorphan does not depress
mucociliary function of the airway mucosa
and is practically devoid of constipating
action.
Though considered non addicting, some drug
abusers indulge in it.
17. Many H1 antihistamines have been conventionally
added to antitussive/expectorant formulations.
They afford relief in cough due to their sedative
and anticholinergic actions, but lack selectivity
for the cough center, may even reduce secretions
by anticholinergic action.
They have been specially promoted for cough in
respiratory allergic states.
Chlorpheniramine (2–5 mg), Diphenhydramine
(15–25 mg) and Promethazine (15–25 mg);
PHENERGAN 5 mg/5 ml elixir) are commonly used.
Second generation antihistamines like
fexofenadine, loratadine, etc. are ineffective.
18. Prenoxdiazine In contrast to other
antitussives, it acts peripherally; desensitizes
the pulmonary stretch receptors and reduces
tussal impulses originating in the lungs.
It is indicated in cough of bronchial origin
19. Bronchospasm can induce or aggravate cough.
Stimulation of pulmonary receptors can trigger
both cough and bronchoconstriction, especially
in individuals with bronchial hyper reactivity
Bronchodilators relieve cough in such individuals
and improve the effectiveness of cough in
clearing secretions by increasing surface velocity
of airflow during the act of coughing.
They should be used only when an element of
bronchoconstriction is present and not routinely
