Bilosomes: Superior Vesicular Carriers

Abstract

In the current era, many formulations have been designed in the form of vesicular carriers like liposomes and niosomes which have been proved to be one of the potential candidates for drug delivery by the oral route but due to the gastrointestinal environment i.e. pH, presence of enzymes, and bile salts, their use is limited. Because of these difficulties, research is being done to increase the stability and efficacy of the drug. Thus bilosomes have been developed as a potential vesicular carrier system for oral vaccine delivery, transdermal and parenteral targeted drug delivery. The present article covers various aspects related to the novel vesicular system that is based on bile salts called bilosomes, for targetted drug delivery systems. It includes information related to bilosome composition, formulation techniques, characterization methods, applications in oral immunization as vaccine delivery approach and advantages over conventional nanocarriers such as liposomes and niosomes. It also focuses on the stability and applications of bilosomes along with scalability and potentiality in biomedical field of oral immunization against various dreadful diseases.
