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

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 int elligent 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 d elivery systems by virtue of their small size and efficient carrier characteristic. The present paper deals with the development and evaluation of stable microsphere of Dilt iazem HCl. various parameters have been reported in present communications.
