Dissolution Testing USP 1/2/5/6

Dissolution tests are used in the pharmaceutical industry in order to characterize the dissolution properties of the active drug, the active drug's release, as well as the dissolution from a dosage formulation. Different dissolution testing methods are available in USP, Ph.Eur., and other internationally harmonized Pharmacopeia. While standard tablets are typically tested using the paddle method (USP 2), swelling or floating dosage forms e.g. capsules are tested according to the basket method (USP 1), whereas paddle-over-disk (USP 5) and rotating cylinder (USP 6) methods are utilized for transdermal dosage forms.
