The objective of present review was to determine the various evaluation tests for controlled porosity osmotic pump tablets. Controlled porosity osmotic pump (CPOP) tablet contains drug, osmogens, excipients in core and a coating of semi permeable membrane with water soluble additives. In CPOP water soluble additives dissolve after coming in contact with water, resulting in an in situ formation of micro porous membrane. CPOP tablets were evaluated for compatibility study, precompression parameters and post compression parameters. The present study gives an idea about various evaluation tests for CPOP tablets.
