Cyclandelate: effect on circulatory measurements and exercise tolerance in chronic arterial insufficiency of the
Insights
Cyclandelate significantly improved circulation in patients with lower limb arterial insufficiency. The drug enhanced blood flow, walking distance, and other key circulatory indicators in a double-blind study.
Area of Science:
- Vascular Medicine
- Pharmacology
- Clinical Trials
Background:
- Peripheral arterial insufficiency is a condition affecting lower limb circulation.
- Limited treatment options exist for improving circulatory status in affected patients.
Purpose of the Study:
- To evaluate the efficacy of cyclandelate in improving circulatory function.
- To assess the drug's impact on both symptomatic and physiological markers of arterial insufficiency.
Main Methods:
- A double-blind, cross-over study involving 39 patients with lower limb arterial insufficiency.
- Measurements included skin temperature, calf blood flow (rest and post-exercise), walking distance, exercise tolerance, and reflex vasoconstriction.
- Patients were treated with either cyclandelate or placebo.
Main Results:
- Cyclandelate treatment led to significant improvements in all measured circulatory indicators.
- Enhanced skin temperature, increased blood flow, and greater walking distances were observed.
- Improved exercise tolerance and reduced reflex vasoconstriction were also noted.
Conclusions:
- Cyclandelate demonstrates significant therapeutic benefits for patients with arterial insufficiency of the lower limbs.
- The drug positively impacts multiple facets of circulatory efficiency, suggesting a valuable role in treatment.
Abstract:
Thirty-nine patients with arterial insufficiency of the lower limbs were treated with cyclandelate or placebo in a double-blind cross-over study, to evaluate the effect of this drug on symptomatic and physiologic indicators of circulatory status. The following measurements were used: skin temperature of the big toe and dorsum of the foot; blood flow in the calf at rest and after exercise on a foot ergometer to the point of claudication; walking distance to the development of claudication; exercise tolerance on a foot ergometer; and reflex vasoconstriction on the skin of the toe in response to cooling of the upper extremities. During treatment with cyclandelate, significant improvement occurred in each of these measures of circulatory efficiency.
