Proniosome: A Promising Approach for Vesicular Drug Delivery

Different types of drug delivery systems are intended to deliver therapeutic agents to the appropriate site of interest to get desired pharmacological effect. In the field of drug delivery, the advancement of nanotechnology helps develop novel dosage forms such as liposome, noisome, and proniosome. Proniosomes are promising drug carriers, that are dry formulations, and after hydration, are converted to noisome dispersion. Dry proniosomal powder can deliver a unit dose of the drug with improved drug stability and solubility. By using this formulation, both the hydrophilic and lipophilic drugs can be delivered through different routes like oral, topical, transdermal, vaginal, etc. This review revolves on different features of proniosomes such as their structure, formulation materials of proniosomes, preparation methods, evaluation, and application.
