Glucocorticoids exert their actions via the glucocorticoid receptor through at least 2 intracellular mechanisms, known as transrepression and transactivation. It has been hypothesized that transrepression is the basis of their anti-inflammatory effects, whereas transactivation has been assumed to cause their

We have prepared polymeric nanoparticles using a blend of poly(lactic acid) and monomethoxy-polyethyleneglycol(PEG)-polylactide block copolymer along with betamethasone disodium phosphate (BP). Nanoparticles have been screened for anti-inflammatory activity using experimental rat models of inflammation. In the present study, we examined
