Drug interactions can occur when two or more drugs are taken together and interact through various mechanisms. This can intensify or reduce a drug's effects, produce new reactions, or increase toxicity. Key interaction types include pharmacokinetic changes affecting absorption, distribution, metabolism or excretion of one or both drugs. Foods like grapefruit can also interact through similar mechanisms like inhibiting drug metabolism. Close monitoring is needed when multiple drugs or foods that may interact are used together.
This document discusses drug interactions, which occur when two drugs are administered together and one modifies the effects of the other. It describes several types of interactions, including drug-drug, drug-food, and drug-environment. Interactions can be quantitative, increasing or decreasing a drug's effects, or qualitative, producing abnormal or new responses. The mechanisms of interactions include pharmaceutical, pharmacokinetic, and pharmacodynamic effects. It is important for doctors to consider potential interactions when prescribing multiple medications to a patient.

nursing management of patient with Empyema pptblessyjannu21
prepared by Prof. BLESSY THOMAS, SPN
Empyema is a disease of respiratory system It is defines as the accumulation of thick, purulent fluid within the pleural space, often with fibrin development.
Empyema is also called pyothorax or purulent pleuritis.
It’s a condition in which pus gathers in the area between the lungs and the inner surface of the chest wall. This area is known as the pleural space.
Pus is a fluid that’s filled with immune cells, dead cells, and bacteria.
Pus in the pleural space can’t be coughed out. Instead, it needs to be drained by a needle or surgery.
Empyema usually develops after pneumonia, which is an infection of the lung tissue. it is mainly caused due in infectious micro-organisms. It can be treated with medications and other measures.
The Ultimate Guide in Setting Up Market Research System in Health-TechGokul Rangarajan
How to effectively start market research in the health tech industry by defining objectives, crafting problem statements, selecting methods, identifying data collection sources, and setting clear timelines. This guide covers all the preliminary steps needed to lay a strong foundation for your research.
"Market Research it too text-booky, I am in the market for a decade, I am living research book" this is what the founder I met on the event claimed, few of my colleagues rolled their eyes. Its true that one cannot over look the real life experience, but one cannot out beat structured gold mine of market research.
Many 0 to 1 startup founders often overlook market research, but this critical step can make or break a venture, especially in health tech.
But Why do they skip it?
Limited resources—time, money, and manpower—are common culprits.
"In fact, a survey by CB Insights found that 42% of startups fail due to no market need, which is like building a spaceship to Mars only to realise you forgot the fuel."
Sudharsan Srinivasan
Operational Partner Pitchworks VC Studio
Overconfidence in their product’s success leads founders to assume it will naturally find its market, especially in health tech where patient needs, entire system issues and regulatory requirements are as complex as trying to perform brain surgery with a butter knife. Additionally, the pressure to launch quickly and the belief in their own intuition further contribute to this oversight. Yet, thorough market research in health tech could be the key to transforming a startup's vision into a life-saving reality, instead of a medical mishap waiting to happen.

This particular slides consist of- what is hypotension,what are it's causes and it's effect on body, risk factors, symptoms,complications, diagnosis and role of physiotherapy in it.
This slide is very helpful for physiotherapy students and also for other medical and healthcare students.
Here is the summary of hypotension:
Hypotension, or low blood pressure, is when the pressure of blood circulating in the body is lower than normal or expected. It's only a problem if it negatively impacts the body and causes symptoms. Normal blood pressure is usually between 90/60 mmHg and 120/80 mmHg, but pressures below 90/60 are generally considered hypotensive.

2. LEARNING OUTCOMES
• Define drug interaction
• Describe the types of drug interactions
• Outline the basic mechanisms of drug-drug
interactions
• Describe drug-food interactions
• Describe the consequences of drug interaction
3. Introduction
• Drug interaction refers to chemical reaction
that occurs when more than one drug or drug
and food are administered together
• Some interactions are both intended or
desired as when drugs are combined to treat
hypertension
• Some interactions are unintended and
undesired
• Interactions occur because patients take more
than one drug due to multiple conditions
4. Consequences of drug interactions
• One drug may intensify the effects of the
other
• One drug may reduce the effects of the other
• The combination may produce a new
response not seen with either drug alone
5. Intensification of effects
• Commonly called “potentiative effect”
• Increased therapeutic effects
• Increased adverse effects
6. Increased therapeutic effects
• Sulbactam administered together with
ampicilin increases effects of ampicillin
• When administered alone, ampicilin
undergoes rapid inactivation by bacteria
enzymes.
• Sulbactam inhibits these enzymes and
prolongs and intensifies the effects of
ampicillin
7. Increased adverse effects
• The interaction between aspirin and Warfarin
• Warfarin suppresses clot formation
• If the dose is too high, it leads to spontaneous
bleeding
• Ironically, the dose has to be high enough to
significally supress clot formation
• Aspirin also suppresses clot formation.
• If administered together with Warfarin, severe
bleeding can occur
8. Reduction of the effects
• Such effects are called inhibitory effects
• Can be beneficial or detrimental
• Inhibitory effects that reduce toxicity are
beneficial
• Inhibitory effects that reduce therapeutic
effects are detrimental
9. Reduced therapeutic effects
• Interaction between propranolol and
Albuterol is such an example
• Albuterol is an antiasthmatic drug which
dilates bronchi
• Propranolol is an antihypertensive
• When taken together, propranolol blocks the
effects of Albuterol
10. Reduced adverse effects
• The use of naloxone to treat
morphine/pethidine overdose is an example
• Naloxone completely blocks the effects of
morphine or pethidine
11. Creation of a unique response
• Rarely combination of drugs produce a new
response
• Alcohol and Disulfiram (antiabuse), a drug
used to treat alcoholism
• A range of responses can occur that are not
seen when either drug is administered alone
12. Basic mechanisms of drug-drug
interactions
• Direct chemical or physical interaction
• Pharmacokinetic interaction
• Pharmacodynamic interaction
• Combined toxicity
13. Direct chemical or physical
interaction
• Usually render both drugs inactive
• Occur when drugs are combined in IV or
injectable solutions
• Frequently but not always, the interaction
produces a precipitate
• Discard such a solution
• NB: not all chemical interactions produce a
precipitate
• Never combine two or more drugs in one
container unless you are sure of their nature
14. Chemical or physical interaction
• Interactions can also occur within a human
body
• BUT the body fluids helps to dilute the drugs
and reduce the effects of chemical interaction
• Hence effects are much less likely than in IV
solutions
15. Pharmacokinetic interactins
• Drugs can affect all the 4 pharmacokinetic
processes
• Altered absorption: mechanisms
– By elevating gastric pH- antiacids can decrease the
ionization of basic drugs in the stomach,
increasing the ability of some drugs to cross
membranes. Acidic drugs have the opposite effect
on
– Laxatives-can accelerate passage of other oral
drugs through the intenstines
16. • Altered absorption
– Suppress peristalsis e.g morphine, atropine-
increasing time of absorption
– Inducing vomiting-leading to decreased
absorption
– Drugs that themselves are not absorbed e.g
cholestyramine, can absorb other drugs onto
themselves leading to decreased absorption of
those drugs
– Reduction of regional blood flow-e.g epinephrine
injected together with anesthesia
17. • Reduced absorption
– Epinephrine cause vasoconstriction leading to
decreased/delayed absorption of the anesthesia
18. Altered distribution
• Competition for protein binding
– When 2 drugs bind to the same albumin,
coadministration of such drugs leads to
competition
– Binding of one or both drugs is reduced
– Plasma levels of free drug increase-
– Theoretically, increase in free plasma drug leads to
increased effect
– However, since the newly freed drug rapidly
undergoes metabolism and elimination, sustained
increased free drug level rarely occur
19. Altered distribution
• Alteration of extracellular pH
– Increased pH in ECF- such a drug will increase
ionization of acidic drug in ECF.
– As a result the administered acidic drug will be
drawn from within cell where the pH was low to
ECF where the pH is high
– Changing the distribution of the drug
– Clinical use in management of poisoning
– E.g aspirin poisoning- give sodium bicarbonate.
20. Altered metabolism
• The most important and most complex
mechanism of drug interaction
• Some drugs increase while others decrease
metabolism of other drugs
• Drugs that increase metabolism of other drugs
do so by inducing synthesis of hepatic drug-
metabolizing enzymes
• Drugs that decrease metabolism of other
drugs inhibit hepatic enzymes
21. Altered metabolism
• The majority of drug metabolism is catalyzed
by CYP450 group of enzymes which is
composed of a a large number of isoenzymes
• Of the P450 isoenzymes, 5 are responsible for
the metabolism of most drugs
• CYP1A2, CYP2C9, CYP2C19, CYP2D6, CYP3A4
22. Altered metabolism
• Drugs that stimulate the synthesis of CYP
isoenzymes are referred to as inducing agents
• E.g is phenobarbital, a member of barbiturate
family
• They induce metabolism of themselves and
other drugs by as much as 2-3 fold
• The increase develops over 7-10 days & rate
returns to normal 7-10 days after withdrawal
of the drug
23. Altered metabolism
• When taken with other drugs, dosage of other
drugs should be adjusted e.g oral
contraceptives dosage should be increased to
protect the woman from pregnancy-or go for
double protection; later decrease when the
inducer is terminated
24. Altered metabolism
• Inhibition of CYP isoenzymes
– If drug A inhibits metabolism of drug B, free level
of drug B rises
– The result may be beneficial or detrimental
– E.g of ketaconazole (antifungal) and cisapride (GI
stimulant) and cyclosporine (immunosuppressant)
– Ketaconazole inhibits CYP3A4 that metabolizes
cisapride and cyclosporine
– Results: cisapride (fatal cardiac dysarhythmias);
cyclosporine (allows clinicians to achieve
therapeutic effects with smaller doses of the drug
which is very expensive)
25. Altered elimination
• Altered renal excretion:
– all 3 phases of renal excretion can be altered
– Filtration; reabsorption and active secretion
– Drugs that reduce cardiac output can reduce
glomerular filtration because less blood flow goes
to the renal system.
27. Interactions at the same site
• These are almost always inhibitory in nature
• Agonist-antagonist interaction
• E.g morphine and naloxone
28. Interactions at different sites
• If the drugs influence the same system, they
can influence the effect/response of the other
• E.g morphine and Diazepam(valium)
• Both of these drugs work on CNS-depressant
effect
• Administration of these together influence the
response of the other
• Reason /rationale behind lytic cocktail
previously used for pre-eclampsia
29. Combined toxicity
• If drug A and drug B are both toxic to the liver,
then giving them together would increase the
toxicity
• E.g isoniazid and rifampicin-both are
hepatotoxic
• However, in treating for TB the combination is
essential
• Be cautious with dosages
30. Minimizing drug-drug interactions
• Minimize polymedicine when possible
• Take a thorough drug history-patients taking
illicit drugs and over-the-counter drugs might
not mention them-so be detailed enough
• Consider dosage readjustments when a
metabolite inducer is added or removed.
• Closely monitor side effects of drugs
32. Food-drug interactions
• Altered metabolism-the grape fruit effect
– Inhibits metabolism of certain drugs
– Drug levels are increased
– HOW?- inhibits CYP3A4 found in the liver and
intestine
– Since inhibition of CYP3A4 in liver is minimal,
grapefruit has less effect on drugs after they have
been absorbed
– Less effect on IV administered drugs-because
intestinal metabolism is not involved
33. The grape fruit juice effect
• Chemicals in grape fruit
– Bargapten & 6’.7’-dihydroxybergamottin are
furanocoumarins
– Naringin & naringenin are flavenoids
• The inhibitory effect persists after grape
fruit juice has been taken
• It does not necessarialy has to be taken
together
• Even up to 3 days post last glass of juice
34. Grape fruit juice effect
• E.gs
– Nifedipine
– Caffeine
– Carbamazepine
– saquinavir
35. Timing of drug administration and
food/meals
• Consider the interactions if any
• Consider the effects of the drug on an empty
tummy if any
• The effects need to be weighed for one to
make a decision
36. Drug-food interactions
• They can lead to drug toxicity or therapeutic
failure
• Decreased absorption
– Food reduces drug absorption hence reduced
onset and peak of effect
– Calcium containing foods decrease absorption of
tetracycline-Tetracycline binds to calcium and
forms an insoluble substance
– High fiber foods decrease absorption of digoxin
