Abstract
A solid form of oral administration of isosorbide 5-mononitrate with a controlled, pH-independent release of the active substance in the gastro-intestinal tract is constituted by a pellet coated with a depot layer and a release prolonging lacquer layer. The lacquer layer contains ethyl cellulose and polymethacrylate in a weight ratio from 3:1 to 3:2. The new form of administration is characterized in that it is less costly to produce.
