Biopharmaceutics Classification System (BCS)

The Biopharmaceutics Classification System (BCS) is a framework used to classify drugs based on their solubility and permeability characteristics. It identifies four categories based on how well a drug dissolves in water and how easily it passes through biological membranes. This classification helps predict how a drug will behave in the body, influencing its absorption and effectiveness. By understanding these properties, researchers and regulators can better design and evaluate medications, ensuring they work as intended when taken by patients.
