BRIEF RESUME OF THE INTENDED WORK:6.1 Need of study:

Hyperlipidemia can be defined as high level of cholesterol and high triglycerides, which are an important risk factor for the initiation and progression of atherosclerosis and ischemic heart disease1. Cardiovascular disease and the resultant complication represent the leading cause of morbidity and mortality in developed countries. Moreover, with advanced life style in developing countries, such as India, particularly in metropolitan cities hyperlipidemia and the resultant pathological condition is making increasingly important contribution to mortality statistics of such countries2.

With the advancement of recent scientific knowledge Statins, Fibrates are the best therapeutic options for Hyperlipidemia. With the boon of modern medicines they are also associated with the several side effects as a curse which demands at most medical attention; statins can cause some common side effect such as GI disturbances, myalgia and elevated liver enzyme3.

During a last decade the practice of herbalism has been witnessed in many parts of the world particularly developed countries. Herb and the herbal remedies demonstrate a significant improvement in the quality of life of a patient particularly in therapeutic challenge disease like cancer, hepatic damage, Parkinsons disease and heart diseases.Moreover such products had been used with apparent safety in traditional societies for many centuries, their introduction into western countries; where they are being combined with pharmaceutical agents possess the possibility of potential interaction between the two groups of substances. The possibility of herbdrug interactions is theoretically higher than drugdrug interactions, could be because synthetic drugs usually contain single chemical entities4,5.

Medohat vati is marketed poly herbal formulation, which claims that it is having antihyperlipidemic activity and it is also used for the treatment of CHD6. Till date there is no scientific data available against Medohat vati for antihyperlipidemic and cardioprotective activity in presence or absence of any scientific drug.

So the present study is designed to demonstrate the effect of Medohar vati on antihyperlipidemic and cardioprotective activity of atorvasatin during induced hyperlipidemia and myocardial dysfunction in different experimental models of animals. 6.2 Review of literatureMedohar vati is marketed poly herbal formulation manufactured by Swami Ramdevs Divya Pharmacy. Medohar vati significantly shows antihyperlipidemic activity and it also benefits in thyroid disorders, rheumatic arthritis and joint pain6.

It is formulated by combining different herbs and in addition to their own activity they also contribute towards antihyperlipidemic activity.

Medohar vati acts by removing disorders of digestive system and then reduces the extra fat in the body.

Statins are most commonly used drug in treatment of Hyperlipidemia. They are competitive antagonists of HMG Co A and lower the blood serum level of LDL by inhibiting cholesterol biosynthesis and by stimulating the receptor-mediated uptake of LDL19.

Atorvastatin is long lasting inhibitor of HMG Co A reductase which has a T of about 18 to 24 hours and reduces the LDL-C 39% to 60%. Clinically it is used to reduce serum cholesterol and in severe drug- resistant dyslipidemia but it also causes some side effect such as myalgia, elevated liver enzyme, headache, GI disturbances20.

6.3 Objective of studyThe objective of the proposed study is to investigate the effect of the poly herbal formulation Medohar vati on antihyperlipidemic and cardioprotective activity of atorvastatin in different experimental models of animals. SPECIFIC OBJECTIVES: To determine the phytochemical constituents of Medohar vati.

To arrive at the therapeutic dose after acute toxicity studies following WHO guidelines. To explore the influence of Medohar vati on antihyperlipidemic and cardioprotective role of Atorvastatin using experimental models such as Triton induced hyperlipidemia and High fat diet induced obesity and hyperlipidemia in rats. To study the effect of Medohar vati on protective activities of Atorvastatin during ECG changes.
