Biopharmaceutics is the study of how the physical and chemical properties of drugs affect their delivery and effectiveness in the body. It focuses on understanding how drugs are absorbed, distributed, metabolized, and excreted, which is crucial for developing safe and effective medications. This field combines principles from pharmacology, pharmacy, and biochemistry to optimize drug formulations. By analyzing factors like solubility and stability, biopharmaceutics helps researchers design better therapies that can improve patient outcomes and minimize side effects.
