A drug dissolution test is a test used to establish the quality of a pharmaceutical product, such as a tablet or capsule. This test is conducted because the drug (often called active ingredient) needs to be released from the product for its absorption into the blood to elicit its therapeutic effect.
The test is conducted in place of a clinical test/study called bioavailability or bioequivalence, a pharmacology/pharmacokinetic study type. The test is the backbone of quality assessment of all tablet and capsule products. It is a requirement of worldwide authorities, including the FDA, Health Canada, etc., and pharmacopeias such as USP, BP, EP, etc.
