Summary

Peripheral arterial disease (PAD) due to lower limb arterial blockages affects significant proportion of the population with an age-adjusted prevalence of approximately 12%. Claudication induced walking impairment can be debilitating and adversely affects social, leisure, and occupational activities in many patients and is associated with higher mortality among PAD patients.

Unfortunately, very few effective therapies are available to improve leg symptoms and exercise performance in PAD patients. Surgery is the last resort but results vary. Therefore, there is a large unmet need for medical therapies that can improve long-term walking performance and functional capacity in PAD patients.

Danshen and Gegen (D\&G) are commonly used Chinese herbal medicine in the treatment of cardiovascular diseases. D\&G study has been extensively researched and continued at The Chinese University of Hong Kong (CUHK) for their antioxidative and vasodilator properties, modulate anti-atherosclerosis and improve arthrogenic athophysiology. Three randomized trials were completed at the CUHK showing D\&G improved lipid profile, vascular function and thinned down the internal layer of the carotid artery. One may expect the same with lower limb arteries. Extensive clinical experiences of use in China and Hong Kong indicated that D\&G are well tolerated and safe.

This project is a randomized control trial to determine the efficacy and Safety of D\&G in improving the functional capacity \& QoL in patients with symptomatic PAD. The results of this study have the potential to change local and international practice in providing a much needed therapeutic option in the treatment of PAD.

Conditions

  • Peripheral Arterial Disease
  • Intermittent Claudication

Interventions

DRUG

Danshen Gegen Capsule

Danshen can dilate blood vessels, reduce the number of angina attacks and significantly improve endothelial function in patients with Coronary Angina Pectoris. Gegen is also effective in dilating cardiovascular and cerebrovascular of the brain, and improving blood circulation. The main active ingredient of Gegen isoflavones is effective in dilating the coronary arteries, improving metabolism in normal and ischemic myocardium and reducing blood pressure, heart rate and myocardial oxygen consumption.
