Abstract
A sustained release oral pharmaceutical form suitable for single daily dose administration has a neutral microgranule coated with a mounting layer of active ingredient and pharmaceutically acceptable binder; and a coating layer of a hydrophobic coating polymer of a non-water soluble cellulose derivative, and at least 20% of inert load in relation to dry weight of hydrophobic coating polymer. The pharmaceutical form has improved resistance to rapid release of active ingredient, particularly in the presence of alcohol.
