Advances in Proniosomes: Harnessing Nanotechnology for Enhanced Drug Delivery

In recent years, the field of drug delivery has experienced remarkable progress as researchers strive to enhance the efficacy and safety of pharmaceutical treatments while ensuring patient convenience and compliance. One notable innovation that has garnered significant attention is the development of proniosomes. Proniosomes represent a novel drug delivery platform that merges the advantageous features of niosomes and liposomes while effectively addressing their inherent limitations. Unlike traditional liquid-based liposomes and niosomes, proniosomes are formulated as dry, free-flowing powders or granules. This dry presentation offers several key benefits, including improved stability during storage and transportation, reducing the risk of drug degradation and extending shelf life. Upon contact with an appropriate medium, such as body fluids or a dispersion medium, these proniosomes readily transform into niosomal structures. This characteristic transformation ensures the controlled release of the encapsulated drug, leading to prolonged drug action and potentially reduced dosing frequency, enhancing patient adherence to therapy. Central to the success of proniosomes is the application of nanotechnology, a discipline focused on manipulating materials at the nanoscale. By leveraging nanotechnology, researchers have achieved significant improvements in the physicochemical properties and drug-loading capabilities of proniosomes. Nanoscale drug carriers can traverse biological barriers more effectively, leading to improved bioavailability and targeted delivery to specific tissues or cells. The purpose of this review article is to provide a comprehensive overview of the recent advances in proniosomes and their application in harnessing nanotechnology for enhanced drug delivery.
