Application of nanocarrier in drug development with special emphasis on liposomes: A review

Liposomes are the nano-scale bilayer structure of phospholipid used as a carrier for a Large Variety of drugs. Both lipophilic and hydrophilic drugs can encapsulate into the liposome and delivered to the body. The purpose behind the preparation of liposomes is to reduce the side effects associated with systemic delivery of drugs as well as it also helps in the protection of biodegradable drugs and molecules such as protein and peptides from body enzymes and fluids. Other than these advantages liposome also have high skin permeation due to structural similarities with the stratum corneum and therefore can be used for the topical delivery of drugs. The various types of liposomes and their application in their marketed products are discussed below in the article.
