Permeability classification
WebAug 3, 2024 · BCS classification system is an important tool for generic drug development. It’s give a comparative evidence between test product and RLD (reference listed drug). Without BCS classification it's so tough to design a generic drug development. Because the solubility and permeability of API highly impact on BE study. WebThe Biopharmaceutics Classification System (BCS) classifies pharmaceutical compounds based on their aqueous solubility and intestinal permeability. The BCS Class III compounds are hydrophilic molecules (high aqueous solubility) with low permeability across the biological membranes.
