Development and evaluation of stable microsphere of Diltiazem hydrochloride, an antihypertensive drug

Abstract

Drug delivery system  that can precisely control the release rates or target drugs to specific the body sites had an enormous impact on the health  care systems carrier Technology offers an intelligent approach for drug delivery by coupling the drug to a carrier  particle such as microsphere nanoparticle liposome etc  that modulates the and absorption characteristic of the drug microspheres  constitute an important part of the particulate drug delivery systems by virtue of their small size and efficient carrier characteristic. The present paper deals with the development and evaluation of stable microsphere of Diltiazem HCl. various parameters have been reported in present communications.
