1: During what trimester is a pregnant woman most at risk for adverse drug reactions with
potential long term consequences?
Correct Answer: 1st trimester (fetus most at risk due to rapid organogenesis).
1. First trimester is critical for organ development (weeks 3-8). Teratogenic drugs can cause major
congenital malformations during this period.
2. FDA Pregnancy Categories (now replaced by Pregnancy and Lactation Labeling Rule – PLLR)
emphasize risk assessment in each trimester. Most teratogenic risk is highest in first trimester.
3. Wrong: Second and third trimesters risks include growth restriction, functional defects, or neonatal
withdrawal, but structural anomalies occur primarily in first trimester.
2: What is BEERS criteria?
Correct Answer: Recommendations of medications inappropriate for elderly (65 and older),
prescriber ultimately decides (American Geriatrics Society Beers Criteria).
1. Beers Criteria lists potentially inappropriate medications (PIMs) for older adults due to increased risk of
adverse effects (falls, delirium, bleeding, cognitive impairment).
2. Examples: benzodiazepines (fall risk), anticholinergics (confusion, constipation), NSAIDs (GI bleed,
renal impairment).
3. Wrong: The criteria are guidelines, not absolute rules; clinical judgment and individual patient factors
must be considered.
, 3: What is the CYP450 (cytochrome P450) system?
Correct Answer: Liver enzyme system where medications are metabolized, can either be inducers or
inhibitors and create drug-drug interactions.
1. CYP450 enzymes (CYP3A4, CYP2D6, CYP2C9, etc.) metabolize approximately 75% of all drugs.
Genetic polymorphisms affect individual metabolism rates (poor, intermediate, extensive, ultrarapid
metabolizers).
2. Inducers increase enzyme activity → faster drug clearance → lower drug levels. Inhibitors decrease
enzyme activity → slower clearance → higher drug levels and toxicity risk.
3. Wrong: Not all drugs are metabolized by CYP450; some undergo renal excretion or conjugation
(glucuronidation).
4: CYP450 inducers
Correct Answer: Speed up metabolism of drugs (drug is cleared faster), drug has lesser effect
(decrease blood levels of drug), elevate CYP450 enzymes.
1. Induction leads to subtherapeutic effects of medications metabolized by the affected enzyme.
Example: Rifampin induces CYP3A4, reducing effectiveness of oral contraceptives.
2. Time course: induction takes several days to weeks to fully develop and similarly to wear off after
stopping the inducer.
3. Wrong: Inducers do not directly cause toxicity; they reduce drug levels, potentially causing therapeutic
failure.
5: CYP450 inducers pneumonic: Bullshit Crap GPS INDUCES rage
Correct Answer: B: Barbiturates, C: Carbamazepine, G: Griseofulvin, P: Phenytoin, S: Sulfonylureas,
St. John's Wort, Rifampin, Alcohol, Phenobarbital.
1. Common inducers: Carbamazepine, Phenytoin, Rifampin, St. John's Wort, Barbiturates, Chronic
Alcohol use, Griseofulvin, Phenobarbital, Sulfonylureas.
2. Clinical impact: When an inducer is added, doses of metabolized drugs may need ↑; when removed,
doses may need ↓ to avoid toxicity.
3. Wrong: Not all inducers affect all CYP isoenzymes equally; specificity matters (e.g., rifampin induces
CYP3A4 strongly).
6: CYP450 inhibitors pneumonic: VISA credit card debt INHIBITS spending on designers like CK
to look GQ
Correct Answer: V: Valproate, I: Isoniazid, S: Sulfonamides, A: Amiodarone, C: Chloramphenicol, K:
Ketoconazole, G: Grapefruit juice, Q: Quinidine.
1. Inhibition leads to increased drug levels and toxicity. Example: Grapefruit juice inhibits CYP3A4,
increasing levels of statins (simvastatin), calcium channel blockers, and cyclosporine.
2. Other important inhibitors: Erythromycin, Clarithromycin, Itraconazole, Ritonavir, Cimetidine.
3. Wrong: Inhibition can occur rapidly (within hours), unlike induction which takes days.
