Cilostazol (pronounced /sɨˈlɒstəzɒl/) is a medication used in the alleviation of the symptom of intermittent claudication in individuals with peripheral vascular disease. It is manufactured by Otsuka Pharmaceutical Co. under the trade name Pletal.
Although drugs similar to cilostazol have increased the risk of death in patients with congestive heart failure, studies of significant size have not addressed people without the disease.
Cilostazol is a selective cAMP phosphodiesterase inhibitor. It inhibits platelet aggregation and is a direct arterial vasodilator. Its main effects are dilation of the arteries supplying blood to the legs and decreasing platelet coagulation.
Cilostazol is approved for the treatment of intermittent claudication. The typical dose is 100 mg twice a day. The effects may take as much as 3 months to be evident.
Interactions and side effects
Possible side effects of cilostazol include headache, diarrhea, abnormal stools, increased heart rate, and palpitations.
Cilostazol, clearly effective for a debilitating condition whose current treatment is often inadequate, is a member of a pharmacologic class that is dangerous to people with severe heart failure and unstudied in other people. Cilostazol has been studied in people without heart failure, without evidence of harm, but much more data would be needed to determine that there is no risk at all. Although cilostazol would not be approvable for a trivial condition the Cardio-Renal Advisory Committee and FDA concluded that fully informed patients and physicians should be able to choose to use it to treat intermittent claudication. Patient and physician labeling will describe the basis for concern and the incomplete information available.
