Abstract:
The present invention relates to controlled porous osmotic pump tablets of high permeable drugs and the preparation process thereof. The controlled porosity osmotic pump tablets do not need to be drilled by laser, but provides controlled porosity for drug release by adding a suitable quantity of pore-forming agents into the semipermeable membrane. In specific embodiments, the present invention relates to controlled porous osmotic pump tablets comprising venlafaxine or metoprolol or pharmaceutically acceptable salts thereof.
