1. A patient is prescribed a drug that is a weak base with a pKa of 8.4. In which
part of the body will this drug be most highly ionized?
Answer: Stomach (pH 1.5-3.5). Weak bases are more ionized in acidic environments,
and ionized drugs are poorly absorbed across lipid membranes.
2. Which pharmacokinetic process is most affected by first-pass metabolism?
Answer: Oral absorption. First-pass metabolism occurs in the liver and gut wall after
oral administration, reducing the amount of active drug that reaches systemic
circulation.
3. The time required for half of a drug concentration to be eliminated from the
body is called:
Answer: Half-life. Half-life determines dosing intervals and duration of action.
4. What does bioavailability refer to?
Answer: The amount of drug that reaches systemic circulation unchanged.
Bioavailability is the fraction of the administered dose that reaches systemic
circulation.
5. What is the CYP450 (cytochrome P450) system?
Answer: A liver enzyme system where medications are metabolized. Enzymes can be
inducers or inhibitors, creating drug-drug interactions.
6. Which statement about CYP450 inducers is correct?
Answer: They speed up metabolism of drugs, causing drugs to have lesser effect.
CYP450 inducers elevate enzyme activity, clearing drugs faster.
7. CYP450 inducers include which of the following?
Answer: Barbiturates, St. John's Wort, and carbamazepine. These are known
inducers, while valproate, isoniazid, and ketoconazole are inhibitors.
8. Which statement about CYP450 inhibitors is correct?
Answer: They inhibit metabolism, increasing blood levels of medications. CYP450
,inhibitors slow or block metabolic activity, raising levels of other drugs dependent on
that enzyme.
9. The study of how genes affect a person's response to drugs is called:
Answer: Pharmacogenomics. This combines genomics and pharmacology to provide
individualized drug therapies.
10. The study of drug movement throughout the body is:
Answer: Pharmacokinetics. Pharmacokinetics focuses on absorption, distribution,
metabolism, and excretion (ADME).
11. The study of the biochemical and physiologic effects of drugs on the body
is:
Answer: Pharmacodynamics. This is the study of the effects of drugs on the body
and the mechanisms by which those effects are produced.
12. A drug with a narrow therapeutic index (e.g., lithium, warfarin) requires:
Answer: More frequent monitoring of serum drug levels. There is a small margin
between therapeutic and toxic doses.
13. What is the BEERS criteria?
Answer: Recommendations of medications inappropriate for the elderly (65 and
older). The BEERS criteria list potentially inappropriate medications for older adults.
14. During what trimester is a pregnant woman most at risk for adverse drug
reactions with potential long-term consequences?
Answer: 1st trimester. The fetus is most at risk during the first trimester due to rapid
growth and organogenesis.
15. Which physiological change during pregnancy impacts pharmacokinetics?
Answer: Increased GFR and decreased bowel tone and motility. These changes can
lead to increased drug excretion and increased drug absorption.
16. A 41-year-old patient complains of increased heart rate after starting Nitro
patches for stable angina. What is an appropriate response?
Answer: Prescribe a beta-blocker to help with this. Beta-blockers suppress
nitroglycerin-induced reflex tachycardia.
17. What is the therapeutic action of organic nitrates (nitroglycerin)?
Answer: Promote vasodilation. Dilation of veins and arteries reduces preload and
afterload, lowering myocardial oxygen consumption.
18. What medication is contraindicated when a patient is prescribed Nitro?
Answer: Inhibitors of PDE-5 (e.g., sildenafil). Concurrent use can cause severe
hypotension.
, 19. Adverse effects of Nitroglycerin include:
Answer: Headache, hypotension, and tachycardia. These are common adverse effects
related to its vasodilatory action.
20. How can we prevent Nitroglycerin tolerance?
Answer: Use the lowest effective dose and an intermittent schedule. This involves
allowing at least 8 drug-free hours every day (usually at night).
21. What is the role of CCBs in variant angina?
Answer: Promote relaxation of coronary artery spasm, increasing cardiac oxygen
supply.
22. What is the role of CCBs in stable angina?
Answer: Promote relaxation of peripheral arterioles, decreasing afterload and
reducing cardiac oxygen demand.
23. Contraindications for Ranolazine include:
Answer: Agents that inhibit CYP3A4 (e.g., grapefruit juice, ketoconazole) and drugs
that prolong the QT interval. These increase the risk of torsades de pointes.
24. What is Ezetimibe?
Answer: A Cholesterol Absorption Inhibitor. It lowers cholesterol by decreasing the
amount absorbed from the small intestine.
25. At what age can statins be prescribed?
Answer: Avoid statin use in children under the age of 10.
26. What is the first-line treatment for an acute gout attack in a patient with
infrequent flare-ups (<3 per year)?
Answer: NSAIDs, such as Naproxen, to help relieve inflammation.
27. A patient tried NSAIDs to relieve a gouty attack, but it hasn't helped. What
is the best response?
Answer: Prescribe a glucocorticoid (Prednisone) to bring down the inflammation and
pain. Glucocorticoids are a good option when NSAIDs are ineffective.
28. Which of the following are first-line medications for neuropathic pain?
Answer: Gabapentinoids (gabapentin, pregabalin) and Tricyclic Antidepressants (e.g.,
nortriptyline).
29. Duloxetine is FDA-approved for which type of pain?
Answer: Diabetic peripheral neuropathy. It is also approved for fibromyalgia.
30. Common side effects of Gabapentin include:
Answer: Dizziness, somnolence, and peripheral edema.
