CPM DPM Part 1 Practice Questions - Certificate in Pharmaceutical Medicine Exam - CPM DPM Part 1 Practice Questions - Certificate in Pharmaceutical Medicine Exam

Question 1

Which parameter best quantifies the intrinsic capability of a drug to activate a specific receptor and elicit a maximal functional cellular response once bound?

Efficacy (Emax) Potency (EC50) Affinity (Kd) Therapeutic Index

Correct Answer:

Efficacy (Emax)

Question 2

An oral investigational drug undergoes extensive hepatic first-pass metabolism. What effect does this primarily have on the drug's pharmacokinetic profile?

It significantly reduces systemic oral bioavailability (F). It prolongs the terminal elimination half-life (t1/2). It increases the steady-state volume of distribution (Vd). It decreases hepatic clearance (CLhep).

Correct Answer:

It significantly reduces systemic oral bioavailability (F).

Question 3

A novel small molecule exhibits very high plasma protein binding (99.5%). If displacement occurs due to a co-administered drug, what is the immediate physiological effect on free drug concentration and clearance?

Transient increase in free drug concentration, leading to increased clearance or tissue distribution until a new steady state is reached. Permanent doubling of total steady-state drug concentration and reduced hepatic metabolism. Immediate reduction in volume of distribution due to decreased cellular uptake. Proportional decrease in renal excretion rate regardless of glomerular filtration.

Correct Answer:

Transient increase in free drug concentration, leading to increased clearance or tissue distribution until a new steady state is reached.

Question 4

What is the primary scientific purpose of performing an Ames bacterial reverse mutation assay during non-clinical toxicology screening?

To detect point mutations and frameshift mutations induced by a test substance in Salmonella typhimurium strains. To evaluate chromosomal structural aberrations in mammalian Chinese Hamster Ovary (CHO) cells. To measure secondary QT interval prolongation in human embryonic kidney cells. To quantify DNA double-strand breaks in vivo in Sprague-Dawley rodent bone marrow.

Correct Answer:

To detect point mutations and frameshift mutations induced by a test substance in Salmonella typhimurium strains.

Question 5

Co-administration of a potent CYP3A4 inhibitor with an investigational drug that is a sensitive CYP3A4 substrate is expected to cause which pharmacokinetic change?

Increased Area Under the Curve (AUC) and prolonged elimination half-life of the investigational drug. Decreased Cmax and increased clearance of the investigational drug. Reduced oral absorption due to P-glycoprotein activation in the enterocytes. Accelerated hepatic biotransformation leading to subtherapeutic blood levels.

Correct Answer:

Increased Area Under the Curve (AUC) and prolonged elimination half-life of the investigational drug.
