Abstract

See full text

The present invention relates to a process for producing solid oral dosage forms with sustained release of active ingredient, comprising at least one active ingredient, a preformulated mixture of polyvinyl acetate and polyvinylpyrrolidone, where appropriate, water-soluble polymers or lipophilic additives and, where appropriate, other conventional excipients, wherein this mixture or parts of this mixture are granulated by heating to from 40.degree. C. to 130.degree. C., and the granules are, after admixture with conventional excipients, subsequently tabletted.
