Micro-particles with polymers have got widespread application in formulation and development of various pharmaceutical and Life Sciences for taste masking, improving bioavailability, creating enteric coating, developing sustained released formulation, colon targeting therapy and developing pH dependent formulations. The development of various polymer helps to develop effective drug delivery system in pharmaceuticals and Life Sciences formulations. This polymer helps to create comprehensive drug delivery platform by improved protection, improved solubility and sustained release effect. These polymers are industry choice for the targeted drug delivery profiles. The objective of current manuscript to evaluate importance of Poly (ε-Caprolactone) and Eudragit® and its application in pharmaceutical and Life Sciences Industry for the development of various type of dosage forms
