An Update on Biomaterials As a Pharmaceutical Excipient in Drug Delivery Systems and Its Pharmaceutical Applications

IntroductionBiopolymers isolated from natural sources may be used as novel excipients having the polymeric nature.These isolated biopolymers have excellent bio-retardant, bio-stabilizer and bio-adhesive property.It has excellent film forming ability, and bio-stability properties.The isolated bio-polymers have excellent drug release rate controlling abilities.Since these are natural and edible in nature, these are biodegradable in nature and may be used as an alternative to standard synthetic and semi synthetic polymers.
