Novel Drug Delivery System

The advancement of pharmaceutical sciences has led to the development of various novel drug delivery systems (NDDS) that improve the efficacy, safety, and patient compliance of therapeutic agents. Traditional drug administration methods often encounter challenges such as poor bioavailability, non-specific distribution, and the need for frequent dosing. To overcome these limitations, several innovative approaches have been explored. Transdermal drug delivery systems (TDDS) allow for sustained drug release through the skin, bypassing first-pass metabolism. Vesicular drug delivery systems (VDDS), including liposomes and niosomes, enhance drug solubility, protect active ingredients, and enable targeted delivery. Floating drug delivery systems (FDDS), are designed to prolong gastric residence time, improving absorption of drugs with narrow absorption windows. Microencapsulation techniques protect drugs from degradation and control release profiles. Mucosal and nasal administration routes offer non-invasive alternatives with rapid onset of action, bypassing hepatic metabolism and providing direct access to systemic circulation or the central nervous system. These systems collectively represent a significant shift towards more precise, effective, and patient-friendly drug therapies.
