Author(s): S.K Jain, S Kashaw, L Rathi, G.P Agrawal

Till date, the development of novel drug delivery systems in veterinary medicines is like a dream for Indian scientists, though partially fulfilled in USA and UK. In veterinary medicines, majority of drug formulations are conventional type that fail to deliver and deposit drug molecule at the desired site. Due to wide variation in animal species, body system and its requirement, considerable flexibility exists with regards to the nature and physical structure of the veterinary device. The novel formulation modifications including sustained release devices, implant using biodegradable polymers, site directed formulations and rumen delivery systems could manipulate pharmacokinetic disposition to extend drug availability to the animal at the desired rate for prolonged period. Present review gives insight into controlled drug delivery systems already existing in veterinary field of medicines, however some are in the process of development.
