Diabetes mellitus has been emerged as one of the major health problems, which is found commonly all over the world. In Ayurveda, inclusion of Madhumeha, in eight major diseases (Ashthamahagada) indicates the gravity and significant attributed to it. In this study a comparative trial between an Ayurvedic compound (Kalpit) named as Madhudaman Yoga, and Glipizide as control drug was carried out. 50 patients of Diabetes mellitus were registered from the OPD and IPD of NIA, Jaipur for this study. These patients were divided into two groups. Group A (control drug) – 25 patients took Glipizide 5 mg twice daily for 75 days. Group B (trial drug) - 25 patients took 2 capsules of Madhudaman Yoga 500 mg, twice daily for 75 days. At the end of the study it was observed that the trial drug showed significant improvement in FBS, PPBS, and HbA1c (p<0.001). Significant relieves in many symptoms were also observed. The overall effect of Madhudaman Yoga was approximately similar to that of the control drug. No side effects were noticed in any of the patients of the trial group.

Introduction

Diabetes mellitus has been classified among one of the major health problems, which is found commonly in socio-economically improved societies all over the world.

According to WHO about 422 million people worldwide have diabetes, the majority living in low and middle income countries, and 1.5 million death are directly attributed to diabetes each year. Both the number of cases and the prevalence of diabetes have been steadily increasing over the past few decades.[1] With an increasing incidence worldwide, DM will be a leading cause of morbidity and mortality for the foreseeable future.[2]

The disease Madhumeha is described in almost all available texts of Ayurveda under the sub type of Vataja Prameha. Its inclusion in eight major disease (Asthamahagada) indicates the gravity and significant attributed to it.[3,4] Acharya Charaka has described the character of excrete urine like pale in appearance, Kashaya and Madhura in taste and warm and Ruksha in Guna.[5] Prabhuta Mutrata (excessive urination) and Avila Mutrata (turbid, unclear appearance) are general cardinal symptoms of Prameha.[6] Vata is provoked due to Dhatu Kshaya both Gambhira and Sarabhoot. The provoked Vata vitiates Oja and excrete by Basti and leads to Madhumeha.[7]

Non enzymatic Glycosylation and Intercellular Hyperglycemia with disturbances in Polyol pathways are two metabolic events appear to be involved in the genesis of the genesis of complication of diabetes.[8]

Ayurveda is the ray of hope, which can contribute in this regard. Diabetes mellitus can be correlated to 'Madhumeha' because they have similarities in etiology, pathogenesis, symptomatology, complications etc. Keeping in view the developing interest in therapeutic diabetology, the realization of the need to analyze Madhumeha from the therapeutic standpoint has emerged. There is no satisfactory treatment available in modern system of medicine for this disease. Therefore, it was decided to evaluate certain Ayurvedic drugs which could be safe, effective economical, easily available having no side effects. For this purpose, an Ayurvedic formulation (Madhudaman Yoga) was selected as trial drug.

Materials and Methods

This study was conducted under a strict protocol to prevent bias and to reduce the sources of error in the study. This control trial study was conducted under the following steps:-
1. Selection of patients

2. Administration of Drug

3. Follow up study

4. Assessment of progress

Selection of patients: A written information and consent letter had been given to patients. The patients were explained about the purpose, procedures and possible dangers of the trial.

The patients for this study were selected from OPD and IPD of NIA hospital, Jaipur after screening them as per Ayurvedic and modern criteria for Madhumeha. Total 50 patients were registered for the study.

Almost all ingredients of Madhudaman Yoga have been described in Ayurvedic Samhitas as parts of Anti Madhumeha Yogas. These all ingredients of Madhudaman Yoga, individually have the capacity to lower blood sugar but in Ghana Satva combination form, the results are tremendous, not only on controlling blood sugar but also dyslipidemia & obesity.

Most of the drugs contained in Madhudaman Yoga have properties like Vata-Kapha Shamak, Deepana, Rasayana, Pachan, Medohara, Shoshana. These are likely to break down the Samprapti of Madhumeha (DM).

This drug probably may increase insulin secretion from pancrease, decrease hepatic gluconeogenesis, increase glucose uptake in the periphery or decrease insulin resistance, further research is required to establish these mechanisms.

No any side effect was detected during the drug trial.

Conclusion

Significance of symptomatic relief in patients taking Madhudaman Yoga is just similar to the effect of the control drug, Glipizide. But no side effect of Madhudaman Yoga was observed in this trial. There is highly significant improvement in FBS, PPBS, HbA1C and PPUS in the patients who were treated with the trial drug.

Statistically significant results was observed in controlling dyslipidemia and this drug was found to be beneficial in weight reduction.
