Abstract Title:
Role of Rutin Nanoemulsion in Ameliorating Oxidative Stress: Pharmacokinetic and Pharmacodynamics Studies.
Abstract:
Parkinson's disease is caused due to free radical generation in dopamine neurons leading to oxidative stress induced damage. The aim of this work was to ameliorate the free radical induced oxidative stress in rats by using TPGS (Tocopheryl polyethylene glycol 1000 succinate) loaded rutin nanoemulsion after oral administration. For this purpose, pharmacokinetic and pharmacodynamics studies were performed in albino wistar rats. Various behavioural tests (photoactometer test, rota rod, akinesia and catalepsy) and biochemical estimations for determination of GSH, TBARS and SOD were carried out. The results showed an increase in relative bioavailability of rutin after oral administration of nanoemulsion as compared to pure drug suspension. The AUC and Cof rutin nanoemulsion after oral administration were 1.8-fold and 1.9-fold higher than those of drug suspension respectively. Pharmacodynamic studies have shown good results with the rutin nanoemulsion than pure drug suspension. The rats treated with the rutin nanoemulsion exhibited significantly greater locomotor activity, better muscle coordination and improvement in cataleptic behaviour than the normal and haloperidol-induced rats (p
