This doc discusses a variety of compendial techniques for drug dissolution testing. It commences by defining dissolution as the process where by a reliable compound solubilizes within a solvent, transferring mass from the reliable area on the liquid section.
Typical apparatus involve the rotating basket, rotating paddle, and movement-by way of mobile. here The rotating basket and paddle are shut-compartment equipment that hold the drug sample. The movement-by way of mobile can be an open method that permits clean fluid to go through a holder made up of the drug sample. Suitable dissolution testing assures regular drug output and predictable overall performance.
