Advances in Drug Delivery Systems: A Review of Recent Developments

Abstract

Drug delivery systems (DDS) represent an essential element of the modern pharmaceutical sciences, since they directly affect the safety, efficacy, and therapy results of medication compounds. Traditional types of delivery systems, oral and injectable formulations, are often faced with constraints such as poor bioavailability, rapid degradation, lack of specificity, frequent dosing timetable, and unpleasant adverse effects. It is these challenges that have prompted the development of superior DDS that seek to maximize the therapeutic efficacy and at the same time, therefore, reduce the toxicity and improve patient compliance.
