Review on Different Vesicular Drug Delivery Systems (VDDSs) and Their Applications.

Background: Colloidal dispersions, also known as vesicular drug delivery systems (VDDSs), are highly ordered assemblies composed of one or more concentric bilayers formed by the self-assembly of amphiphilic building blocks in the presence of water.

Objective: VDDSs are important to target the entrapped drugs at specific sites inside the body, control the drug release, enhance the drug bioavailability, and reduce undesired side effects.

Methods: There are different types of VDDSs suitable for the entrapment of both hydrophilic and lipophilic drugs.
