Abstract
Parkinson’s disease (PD) is a progressive neurodegenerative disorder requir-ing continuous dopaminergic stimulation. The primary pharmacological treatment, Levodopa (often combined with Carbidopa), suffers from a narrow absorption win-dow confined to the proximal small intestine. Conventional dosage forms lead to fluctuating plasma drug levels, resulting in ”on-off” motor fluctuations. To over-come these pharmacokinetic limitations, Gastroretentive Floating Drug Delivery Systems (FDDS) have emerged as a promising strategy. This paper reviews and investigates the advancement of FDDS in prolonging the gastric residence time (GRT) of anti-Parkinson’s drugs, thereby ensuring sustained release and improved bioavailability. The study presents a comprehensive framework, formulation param-eters, and analytical results demonstrating the efficacy of floating matrix systems using hydrophilic polymers like HPMC.
