A brief overview of sustained released drug delivery system

The most popular and patient-friendly method of drug administration is often thought to be the oral route administration. Compared conventional release formulations, advancements in formulation technology, including modified dosage forms or sustained forms, have been extensively accepted. A form provides a prolonged over an extended period, thereby giving better patient compliance enhanced bioavailability. Sustain systems are considered wiser approach for drugs with short half-lives requiring repeated dosing. Sustained delivery has range advantages increased due less frequent administration, significantly reduced steady state level fluctuations, maximum utilization, safety margin potent drugs, lower healthcare costs improved therapy, shorter treatment times. present review focuses on design, fabrication, various factors that influence performance sustained-release forms.
