Question 1

The rate at which monolithic devices transfer drugs to the patient body is proportional to _______________ of time

Accepted Answer

The rate at which monolithic devices transfer drugs to the patient's body is proportional to the square root of time. This is based on the Higuchi equation, which describes drug release from a solid matrix as a square root of time-dependent process.

Question 2

What are the characteristics of the reservoir or membrane devices?

Accepted Answer

The answer of What are the characteristics of the reservoir...

Question 3

What are the characteristics of the mixed monolithic-reservoir devices?

Accepted Answer

Mixed monolithic-reservoir devices have a drug-polymer matrix that is layered by a rate-controlling membrane, which regulates the release of the drug.

Question 4

The absorption of the ophthalmic drug does not depend on which of the following?

Accepted Answer

The size of the eyeball does not affect the absorption of ophthalmic drugs. Factors like physicochemical properties, tear drainage, and tear output can influence drug absorption.

Question 5

Which of the following is false in regarding reservoir devices?

Accepted Answer

Reservoir devices typically contain the drug in a core surrounded by a rate-controlling membrane, not in a powder form floating on liquid.
