The Role of the Moistening Agent in the Process of Extrusion and Spheronization

Overview

The pellet is an important oral dosage form, interesting because of its numerous technological andpharmacotherapeutic advantages. Extrusion/spheronization is one of the most frequently employedtechnologies of pellet manufacture. Similarly as other technologies, also this process of manufactureinfluences a number of manufacturing and formulating parameters, which are then reflected in thefinal properties of produced pellets. The present experimental paper is concerned with the role ofthe moistening agent in the process of extrusion/spheronization and the examination of its effect onthe size, density, shape, and mechanical and flow properties of pellets.

Key words:
pellets – extrusion/spheronization – amount of the moistening agent –properties of pellets
