In order to develop an efficient drug delivery carrier it is important for it to possess the following qualities. It should be immediately and completely removed after delivering drugs, it should not be accumulative or toxic in nature. Recent studies have proved the applicability of some chitin derivatives such as carboxymethyl chitin (CMC), chitosan hydrogel, and hydroxy-ethyl chitin have been shown to possess such characteristics (Ishihara et al., 2006 Dev et al., 2010).
