In-Vivo assessment of glucocorticoid loaded tea tree oil nanoemulsion gel
Optimized formulations were subjected to various in vivo studies like anti-inflammatory activity, Nickel induced dermatitis, irritation study and Acute and repeated dose dermal toxicity studies. Clobetasol propionate (CP) has anti-inflammatory, immunomodulatory, and antiproliferative activity. The aim of the present work was to test the hypothesis that the addition CP in nanoemulsions would result in enhancement CP delivery and leading to better antipsoriatic activity. Nanoemulsions were prepared by aqueous phase titration method, using Tea Tree oil, Tween 20, Transcutol P, and distilled water as the oil phase, surfactant, co-surfactant and aqueous phase, respectively.We developed a topical O/W nanoemulsion in which drug is incorporated in disperse phase of oil and evaluated its efficacy against different types of in vivostudies. It was also found that the significantly increased their anti-inflammatory activity. It was reported that CP-loaded nanoemulsion significantly increased NTPDase (Nucleoside triphosphate diphosphohydrolases) activity in lymphocytes. This membrane protein is responsible for the hydrolysis of extracellular ATP (Adenosine triphosphate) which is responsible for cell proliferation, differentiation and inflammatory processes. In vivoirritation studies did not show any irritation in spite of having high amount of surfactant. Group treated with CP loaded nanoemulsion gel showed no evident toxicity even on repeated exposure. On the basis of above in vivo study we conclude that developed nanoemulsion is safe for human.
