Dissolution tests serve both as qualitative tests of medicinal products and on the other hand, provide valuable information during formulation of new ones. The aim of this work was to study the dissolution process of diclofenac sodium from suppositories. The theoretical part focuses on the description of dissolution methods, the preparation of suppositories and the active substance used. The tested suppositories were prepared by three methods (manually, by Unguator technology and industry made ones), in experimental part.
