Drug release is a research area that focuses on understanding and controlling the ways in which drugs are released from dosage forms, such as tablets, capsules, patches, or implants, into the body. This field involves studying the factors that influence drug release, such as the drug's chemical properties, the formulation of the dosage form, and the physiological conditions of the body. Researchers in this area aim to design drug delivery systems that can release drugs at the desired rate and in the desired location to optimize therapeutic outcomes while minimizing side effects. This research is important for improving the effectiveness and safety of drug treatments for various diseases and conditions.
