Q. |
The absorption of the ophthalmic drug does not depend on which of the following? |
A. | physicochemical properties of the permeating molecule |
B. | drainage of tears |
C. | output of tears |
D. | size of the eyeball |
Answer» D. size of the eyeball | |
Explanation: the absorption of the ophthalmic drug across the corneal membrane is a diffusion process and depends largely on the physicochemical properties of the permeating molecule that is the drug. it also depends upon the drainage and output of tears. drugs of ophthalmic use are such as atropine, local anesthetics, epinephrine, etc. |
