Aim: The primary objective of the study was to investigate the possible effects of 70% Ethanolic extract of Enicostemma littorale Blume on adrenaline induced hypertensive rats. The hypertension was induced by Adrenaline at dose of 0.5 mg/kg i.p for 5 consecutive days. Materials and Methods: The test doses of 250, 333.33 and 500mg of 70% Ethanolic extract of Enicostemma littorale (EEEL) and 10mg Propanolol were given orally and Intraperitonially respectively for 7 days. The various biochemical parameters like blood glucose, serum triglyceride, cholesterol, serum creatine phosphokinase, lactate dehydrogenase were measured. Results: The extract administered groups had shown significantly lowered in LDH, CPK and pulse rate comparing to the normal groups. The biochemical parameters were lowered and significantly different (P˂0.01), when compared with the disease control. Conclusion: It can be concluded that 70% EEEL imparted a protective action against adrenaline induced hypertension in rats.

: Ascorbic acid is an essential nutrient, and required for various metabolic activities in humans. Typically citrus fruits, vegetables and organ meat are good source of Vitamin C. It acts as strong antioxidant and act as a scavenger in defence against free radical oxygen species. It has also contributed to rejuvenate photo aged skin. It has ability to control the pigmentation of melanin by inhibiting the enzyme tyrosinase by interacting with copper ions. It serves as a coantioxidant with vitamin E to regenerate alpha tocopherol, thereby retards cellular damage. Ascorbic acid is deprotonated to form ascorbate anion, contributes to its prooxidant properties and act as a potential anti-cancer agent. It reduces the mutation rate in mismatch-repair deficient human colon cancer cells. Ascorbic acid is a phytochemical has micronutrients that act against the inflammation in arthritis. Currently, challenges lies finding most stable formulation for achieving optimum results as shown in Fig. 1.

Acyclovir sodium is an antiviral drug used to treat herpes, chicken pox and herpes skin infections. Acyclovir sodium potential as an antiviral drug is limited by its low oral bioavailability (20-30%) with short half-life (2-3 hours) with poor plasma protein binding. There is an opportunity to utilize Acyclovir sodium as an antiviral drug by enhancing the bioavailability by formulation technology. In this paper solid microparticle (o/w) of Acyclovir was prepared by melt dispersion technique. The characterization of drug using scanning electron microscopy, FT-IR, particle size, percentage yield, drug loading capacity, hausner's ratio and carr's index, bulk density and tapped density. In vitro drug release studies using phosphate buffer has shown as formulation F5 sustained release for 17 hrs.
