Abstract
Background: For several years, many attempts have been made for the improvement of liposomal stability. In 1986, Payne et al, introduced the concept of Pro-liposome for liposome preparation in order to avoid physicochemical instability encountered in some liposome suspensions such as aggregation, fusion, hydrolysis, and/or oxidation. Objective: The objective of this review is to focus on different aspects related to Proliposomes, their method of preparation, characterization techniques and pointing out its scope in drug delivery systems. Methods: Proliposomes are a new form of drug delivery systems. They are dry, free-flowing granular products composed of drug and phospholipid which, upon addition of water, disperse to form a multi-lamellar liposomal suspension. Results and Discussion: These Proliposomes are nearly as good as or perhaps better than conventional liposomes. In the present review attempt has been made to briefly explain the concept of Proliposomes with a focus on its components, preparation, characterizations and their field of application. Conclusion: Extensive survey of literatures and collected data suggests that Pro-liposomes are promising drug carriers for the future.
