Dissolution and Drug Release Tests

Dissolution and drug release tests are in vitro tests that measure the rate and extent of solution formation of a solid state from a drug product. They are used, in most cases, as a measure of drug product performance in vitro. USP provides procedures and other information on the dissolution or drug release testing of different dosage forms organized along routes of administration. Learn about the USP dissolution test.
