2026 FULL QUESTIONS AND CORRECT
ANSWERS
◉ What is the strength of a bond between a drug and its receptor?.
Answer: Affinity
◉ What is the extent to which a drug activates a receptor it is bound
to?.
Answer: Intrinsic activity
◉ Pharmacokinetic interactions.
Answer: Interactions that affect absorption, metabolism, or
excretion of drugs.
◉ Pharmacodynamic interactions.
Answer: Interactions that can be additive, synergistic, or
antagonistic.
◉ Polypharmacy.
,Answer: The concurrent use of multiple medications, which greatly
increases the risk of drug interactions.
◉ What is hepatic drug metabolism?.
Answer: The process by which the liver chemically alters drugs,
primarily through the cytochrome P450 enzyme system, to facilitate
their elimination from the body.
◉ What is the cytochrome P450 enzyme system?.
Answer: A group of enzymes in the liver that play a crucial role in
the metabolism of many drugs by facilitating their chemical
modification.
◉ What are inducers in drug metabolism?.
Answer: Substances that increase the activity of enzymes, leading to
a decrease in drug levels in the body.
◉ What are inhibitors in drug metabolism?.
Answer: Substances that decrease the activity of enzymes, resulting
in an increase in drug levels in the body.
◉ How does liver disease affect drug clearance?.
Answer: Liver disease can reduce the clearance of drugs, increasing
the risk of toxicity due to accumulation.
, ◉ What is half-life in pharmacology?.
Answer: The time required for the concentration of a drug in the
bloodstream to decrease by 50%.
◉ How does half-life affect drug dosing?.
Answer: Half-life determines the dosing frequency and the time
required to reach steady-state drug levels in the body.
◉ What is the significance of a longer half-life?.
Answer: A longer half-life increases the risk of drug accumulation
and potential toxicity.
◉ What are ways to minimize adverse drug reactions?.
Answer: 1. Use the lowest effective dose. 2. Adjust for renal/hepatic
impairment. 3. Avoid unnecessary polypharmacy. 4. Monitor labs
and clinical response. 5. Educate patients.
◉ Inducers.
Answer: Carbamazepine
Rifampin
Alcohol
Phenytoin
