Dissolution Testing of Immediate Release Solid Oral Dosage Forms

FinalCenter for Drug Evaluation and Research08/25/1997

Description

The Food and Drug Administration (FDA) is announcing the availability of a guidance for industry entitled ``Dissolution Testing of Immediate Release Solid Oral Dosage Forms.'' The purpose of this guidance document is to provide general recommendations for dissolution testing, approaches for setting dissolution specifications related to biopharmaceutic characteristics of the drug substance, statistical methods for comparing dissolution profiles, and a process to help determine when dissolution testing is sufficient to grant a waiver for an in vivo bioequivalence study. This guidance document also provides recommendations for dissolution tests to help ensure continuous drug product quality and performance after certain postapproval manufacturing changes.
