Specification Setting for IR BCS 1 & 3 Drugs For BCS Class 1 and 3 products: • These recommendations will supersede those in the Dissolution Methods Database, and upon finalization of this guidance FDA will update the Dissolution Methods Database or remove entries from the Database that are covered by this guidance. Free house plan design software. Criteria may expand the number of Class 1 drugs eligible for a biowaiver of in vivo bioequivalence (BE) studies and provide predictability of drug disposition profiles for Classes 2, 3, and 4 compounds.
List Of Bcs Class 1 Drugs
The biopharmaceutical classification system (BCS) classifies compounds based on their solubility and permeability. Regulatory agencies and health organizations have utilized this classification system to allow dissolution to be used to establish bioequivalence for highly soluble and highly permeable compounds. The pharmaceutical industry has taken advantage of this and BCS-based waivers are becoming more routine and result in significant savings. Further, there is strong scientific rationale to allow BCS-based waivers for even more compounds to realize even more savings.

Yet just as clear as the benefits are the barriers that limit application: lack of international regulatory harmonization, uncertainty in regulatory approval, and organizational barriers within the pharmaceutical industry. Once these barriers are overcome and additional applications are fully allowed, the full benefits of BCS applications will be realized. INTRODUCTION Amidon et al. First proposed a biopharmaceutic classification system (BCS) in 1995, that classified compounds based on their solubility and permeability ().

Subsequently, regulatory agencies and health organizations have utilized this classification system to allow in vitro dissolution to be used to establish bioequivalence for highly soluble and highly permeable compounds (). The pharmaceutical industry has taken advantage of dissolution and BCS-based waivers of in vivo studies; however, this is not the only instance where application of the BCS is beneficial. Rather, its principles are used throughout development. A series of case studies are presented to illustrate uses of BCS through out the clinical development cycle followed by a discussion of its implementation in that aspect of clinical development. Case Study I—Use of the BCS in Formulation Development Pregabalin (Lyrica®) is described chemically as ( S)-3-(aminomethyl)-5-methylhexanoic acid.
