REVIEW ON CASEIN PRODUCTION AND CASEIN BASED NANO-FORMULATIONS

Abstract

Biodegradable systems have the ability to release the drug for a prolonged period of time and subsequently degrade which can be easily cleared from the body. This property makes use of them for the design of carriers for the controlled delivery of therapeutic agents, since it will release the entrapped drug over an extended period of time. Due to its non toxic, biocompatible and slow digesting nature it is an effective matrix in drug delivery. Milk has many proteins, including the nine essential amino acids. The two basic types of proteins in milk are called casein and whey. The ability of casein to modify drug dissolution from compacts was reported. The high tensile strength of casein film, favours its use as an acceptable film-coating for tablets. Casein floating beads were developed to increase the residence time of drugs in the stomach based on its emulsifying and bubble-forming properties. Casein-based microparticles bioactive molecules were prepared via emulsification-chemical cross linking Casein nanoformulations were also prepared to deliver nutraceuticals and synthetic drugs via enzymatic crosslinking, graft copolymerization, heat-gelation and polyelectrolyte ionic complexation. It can be concluded that casein-based formulations are promising materials for controlled drug delivery.
