Question 2

Which excipient functions as a disintegrant in tablet formulations?

Accepted Answer

Sodium starch glycolate

Answer

Sodium starch glycolate is a superdisintegrant that rapidly absorbs water and swells, breaking the tablet apart.

Question 3

The Noyes-Whitney equation describes the rate of drug dissolution as dependent on:

Accepted Answer

Surface area and concentration gradient

Answer

The Noyes-Whitney equation: dM/dt = DA(Cs−C)/h, where surface area and concentration gradient are key variables.

Question 4

Enteric coating on tablets is designed to dissolve at a pH above:

Accepted Answer

5.5

Answer

Enteric polymers like cellulose acetate phthalate dissolve above pH 5.5–6.0, allowing intact passage through the acidic stomach.

Question 5

Which parameter best describes the spread of residence times of molecules passing through a flow-through system in pharmacokinetics?

Accepted Answer

Mean residence time (MRT)

Answer

MRT represents the average time a drug molecule resides in the body and accounts for all disposition processes.
