Cilostazol, sold under the brand name Pletal among others, is a
Common side effects include headache, diarrhea, dizziness, and cough.
Cilostazol was approved for medical use in the United States in 1999.
Medical uses
Cilostazol is approved for the treatment of intermittent claudication in the United States and United Kingdom.[2][5]
Cilostazol is also used for secondary stroke prevention,[2] though to date no regulatory body has approved it specifically for that indication.
Heart failure
Cilostazol is dangerous for people with severe heart failure. Cilostazol has been studied in people without heart failure, without evidence of harm, but much more data would be needed to determine no risk exists. 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.[6]
Adverse effects
Possible side effects of cilostazol use include headache (the most common), diarrhea, severe heat intolerance, abnormal stools, increased heart rate, and palpitations.[7]

Mechanism
Cilostazol is a selective inhibitor of phosphodiesterase type 3 (PDE3) with therapeutic focus on increasing cAMP. An increase in cAMP results in an increase in the active form of protein kinase A (PKA), which is directly related with an inhibition in platelet aggregation. PKA also prevents the activation of an enzyme (myosin light-chain kinase) that is important in the contraction of smooth muscle cells, thereby exerting its vasodilatory effect.
