Title
(EN) METHOD OF PRODUCING MULTI-LAYER MEDICAMENTS IN SOLID FORM FOR ORAL OR RECTAL ADMINISTRATION
(FR) PROCEDE DE PREPARATION DE FORMES GALENIQUES SOLIDES MULTICOUCHES POUR ADMINISTRATION ORALE OU RECTALE
Abstract
(EN)




The invention concerns a method of producing multi-layer medicaments in solid
form for oral or rectal administration. At least
two substances, which each comprise a thermoplastic, pharmacologically
acceptable polymer binder which is soluble or can swell in a
physiological environment, at least one of the substances comprising a
pharmaceutical active substance, are coextruded and the coextruded
multi-layer material is shaped to form the desired medicament.
