There is always a need for better antiflammatory drugs for conditions like atopic Keywords:
dermatitis. A newer formulation is biopolymer based fluticasone propionate .This study was done to compare the efficacy of mometasone furoate with biopolymer with mometasone furoate (Elocon) and betamethasone valerate with biopolymer with betamethasone valerate(Betnovate) in animal models of superficial skin inflammation in rats. The inflammatory model croton oil ear edema of topical administration in rats was used. In this model, the animals treated with mometasone furoate with biopolymer showed a significant decrease in inflammation as compared to mometasone furoate (Elocon) and betamethasone valerate with biopolymer as compared to betamethasone valerate (Betnovate). 1. INTRODUCTION
In this study we are comparing the anti- inflammatory activity of Elocon with a new Inflammation though a protective formulation mometasone furoate with mechanism, in some situations if untreated biopolymer on superficial skin inflammation can lead to serious complications. To know the efficacy of drugs used in inflammation various animal models are used. 2. MATERIALS AND METHODS

Fluticasone propionate is moderately potent glucocorticoid with anti-inflammatory and immunosuppressive properties. This drug is available in various forms and one of them is mometasone furoate marketed as Elocon. Bairy KL et al,J Biosci Tech, Vol 3 (1),2012,446- 448 ISSN:0976-0172

USING NIACIN AND AVOIDING SIDE EFFECTS The vitamin Niacin (B-3) given in pharmacologic amounts is a very effective medication to combat atherosclerosis and reduce the risk of heart attack and stroke. It has been used for decades but eclipsed in recent years by statin drugs (Lipitor, Zocor, etc.) which are more potent in lowering the LDL so called "bad" cholesterol. However, it i
