| Abstract | A coating material for controlling drug release, useful for long acting formulations (e.g. for once-a-day administration), and a long acting granular composition comprising a drug (especially one conventionally difficult to prepar in long acting form) coated with the coating material. This composition may be mixed with other granular drug formulations. The drug-release controlling coating material may comprise, in a specific ratio, specific water-insoluble and low water-permeability polymer and two materials differing from each other in the pH-dependency of their solubility (pH-dependent polymer materials). |
