Drug release refers to the process by which a pharmaceutical compound is released from its dosage form, such as a tablet or capsule, into the body. This process is crucial for ensuring that the drug reaches its target site in the body at the right time and in the right amount. Factors influencing drug release include the formulation of the drug, the method of administration, and the physiological conditions in the body. The rate and extent of drug release can significantly affect the drug's effectiveness and safety. Controlled release systems, such as liposomes or polymeric nanoparticles, are designed to regulate the release of drugs over time, improving therapeutic outcomes and minimizing side effects. Understanding drug release mechanisms is essential for developing effective medications.
