Discriminatory Dissolution Method Development and ...
In general, dissolution tests are useful for (1) assessing the characteristics of the active pharmaceutical ingredient (API) such as the particle size and the crystal form; (2) guiding development of new formulations; (3) assisting in proper formulation selection (selection of excipients) and optimizing the manufacturing process (e.g., compression
