EUDRAGIT: A VERSATILE AND ROBUST PLATFORM

In many aspects, polymeric materials have a pre-eminent position among excipients as they form the backbone of modern pharmaceutical formulations and drug delivery technologies in particular. A polymer is a natural, semi-synthetic or synthetic substance that is combined with a drug or other active pharmaceutical ingredient or excipient to release the drug in a pre-programmed manner. The drug delivery system focuses particularly on the enhancement of bioavailability, site-specific release, mucoadhesive release, sustained release, controlled release, targeted release. For achieving different release patterns as mentioned above different types of polymers are needed. Though there are various natural semi-synthetic and synthetic polymers available Eudragit polymers always have special consideration during polymer selection as it can offer a variety of grades which are useful during product development for any of the above-mentioned purpose. This article reviews Eudragit polymers in terms of usefulness during pharmaceutical applications. Eudragit polymers that are chemically Polymethacrylates are synthetic cationic, anionic and non-ionicpolymers of dimethyl-aminoethyl methacrylates, methacrylic acid and methacrylic acid esters in varying ratios. Eudragit polymers play a pivotal role in the formulation and development of different types of dosage forms with versatile applications.
