Pharmacokinetic studies have demonstrated that Omeprazole and Erythromycin significantly increased the systemic exposure of Cilostazol and/or its major metabolites. Population pharmacokinetic studies showed higher concentrations of Cilostazol among patients concurrently treated with Diltiazem.
The most common side effects are headache, diarrhoea, vomiting, leg cramps, rash etc. The less frequent side effects are anorexia and edema.
There are no adequate and well controlled studies in pregnant women. Transfer of Cilostazol into milk has been reported in experimental animals. Because of the potential risk to nursing infants, a decision should be made to discontinue nursing or to discontinue Cilostazol.
Cilostazol should be used with caution in patients with any degree of heart failure. There is no information with respect to the efficacy or safety of the concurrent use of Cilostazol and Clopidogrel.
