PK final review Part 1

Front

What is the effect of pH on the total drug concentration of weak acids in pH-partition therapy?

Back

The total drug concentrations of a weak acid will be high on the side of the membrane when pH is higher.

Front

What is a characteristic that bioequivalent drug products do not possess?

Back

They contain the same inactive ingredients.

Front

What is true about renal clearance in relation to total body clearance?

Back

Renal clearance cannot exceed the total body clearance.

Front

What happens to Cmax when ka increases?

Back

Cmax increases.

Front

For which route of drug administration is absorption irrelevant?

Back

Intravenous.

Front

Define bioequivalence in pharmacology.

Back

Bioequivalence refers to the property where two drugs have similar bioavailability and produce the same effect at the site of action.

Front

What is the significance of Tmax in pharmacokinetics?

Back

Tmax is the time it takes for a drug to reach its maximum concentration in the bloodstream.

Front

Explain the concept of volume of distribution (Vd).

Back

Volume of distribution is a pharmacokinetic parameter that describes the extent to which a drug is distributed in body tissues compared to the plasma.

Front

What does AUC stand for and why is it important?

Back

AUC stands for Area Under the Curve; it represents the total drug exposure over time and is crucial for understanding drug bioavailability.

Front

What is the relationship between clearance and half-life of a drug?

Back

Clearance is inversely related to the half-life; as clearance increases, the half-life decreases.
