The Pharmaceutical Development and Bioavailability of Cimetidine Capsule and Tablet Formulations

Abstract
The development of a suitable oral solid dosage form of cimetidine has been examined from the standpoint of equal bioavailability for different formulations. The in vitro characteristics of one capsule and four tablet formulations were determined. From the areas under the blood level/time curves in healthy volunteers, equal bioavailability was shown between the capsule, the original tablet formulation chosen for early clinical trials and the final tablet formulation used for commercial production.
