Dissolution refers to the process of breaking down or dissolving a substance into smaller molecules or particles in a solvent. This process is commonly studied in the fields of chemistry and pharmaceuticals, as it plays a crucial role in the absorption and effectiveness of drugs in the body. Dissolution testing is used to evaluate the rate at which a drug dissolves in a specified medium, which can impact its bioavailability and therapeutic effects. Researchers investigate various factors that can influence dissolution, such as temperature, pH, agitation, and the physical properties of the drug formulation. By understanding dissolution behavior, scientists can optimize drug formulations for improved effectiveness and patient outcomes.
