Polymers like HPMC, HPC etc are broadly explored these days. Also a combination of these with Polyox can be tried in different concentrations depending on desirable profile.
Thank you Harita for your valuable information. Actually we are interested in newly synthsized polymers. We already have synthsized PGA, PGA-Co-Caprolactone and Pentadecalactnes etc and want to use them in drug formulations..
