Polyethylene oxide polymer is employed as a directly compressible binder matrix for therapeutically active dosage forms. Advantageously, the polyethylene oxide has an adjustable rate control effect on the release of medicament from the dosage form, enabling in particular the preparation of sustained release dosage forms.
