Pharmaceutical profile of vitamin C tablets and capsules.

This study examines the pharmaceutical profile of 3 brands of immediate-release vitamin C tablets (500 mg) available commercially in North Carolina and 3 batches of vitamin C capsules (500 mg) extemporaneously prepared in our laboratory. Several pharmaceutical tests were performed on 3 bottles from 3 different brands of immediate-release vitamin C tablets that were purchased from local stores. The brands were compared with respect to thickness, weight variation, hardness, dissolution, disintegration time, and content uniformity tests.
