There are limited long-term safety data regarding its use with aspirin, clopidogrel or warfarin. Cilostazol is contraindicated in patients with congestive cardiac failure, previous ventricular arrhythmias and prolonged QT, and those with significant bleeding history. It should be avoided in moderate to

severe hepatic dysfunction and renal dysfunction (eGFR less than 25ml/min/1.73m2). Frequently encountered adverse effects leading to discontinuation of the drug include headache, palpitations and diarrhoea. Other significant side effects GSI-IX mw include thrombo-cytopenia, agranulocytosis, cardiac disorders and allergic reactions. Since 1998 several randomised controlled trials have been published assessing the therapeutic use of cilostazol Ivacaftor nmr for intermittent claudication. One of the largest initial multicentre, randomised, doubled-blinded

trials, conducted by Beebe et al.,1 compared cilostazol with placebo. The study included 516 men and women aged over 40 years with moderately severe chronic intermittent claudication. Patients were randomised to receive cilostazol 100mg, cilostazol 50mg or placebo twice daily for 24 weeks. Outcome measures included walking distances using treadmill testing, quality of life measures and cardiovascular and all-cause mortality. Improved walking distances were observed as early as four weeks in both cilostazol groups compared with placebo. The cilostazol 100mg twice daily group (n=138) had the greatest benefit at 24 weeks; the pain-free walking distance increased from 70.4m to 137.9m, a 59% geometric mean improvement, compared to 20% in the placebo group (p<0.001) and the maximal walking distance increased from 129.7m to 258.8m. A meta-analysis2 of eight randomised, placebo-controlled trials of cilostazol for intermittent claudication included 2702 patients with stable, moderate to severe intermittent claudication over 12 to 24 week trial periods. Similarly, cilostazol 100mg twice daily was found

to significantly improve pain-free walking distance by 67% and maximal walking distance by 50% (p<0.05). Subgroup analysis for gender, age and diabetes found no differences. Decitabine nmr Two studies included comparison to another therapeutic agent available for intermittent claudication, pentoxifylline, and found it to be comparable to placebo. The same two studies also measured plasma lipids and found that cilostazol 100mg twice daily increased HDL cholesterol by 12.8% and decreased triglycerides by 15.8% at 24 weeks; this was significant when compared to placebo and pentoxifylline. Initial studies were not powered to detect significant efficacy in the population with diabetes. Another meta-analysis3 examined eight phase III trials looking specifically at the use of cilostazol 100mg twice daily compared to placebo in diabetic and non-diabetic patients.
