The porous osmotic pump based drug delivery system for excellent controlled release of drug for 24 hrs. The
porous osmotic pump contains pore forming water soluble additives in the coating membrane, which after coming in contact
with water, dissolve, resulting in an in situ formation of a microporous structure. The porous osmotic pump delivery
from this system is not influenced by the different physiological factors. The present review is concerned with the patent
study of drug release through controlled porous osmotic pump. This patent review is useful in knowledge of controlled
porous osmotic pump for its application.
Keywords: Controlled porous osmotic pump (CPOP), osmotic pump, physiological factors
