Cilostazol is indicated for the reduction of symptoms of intermittent claudication, as indicated by an increased walking distance.
Cilostazol is a preparation of Cilostazol which is a quinolinone derivative. The mechanism of action is to specifically inhibit cellular phosphodiesterase III (PDE III) and suppress cAMP degradation with a resultant increase in cAMP in platelets and blood vessels, leading to inhibition of platelet aggregation and vasodilation.
Dosage & Administration
The recommended dosage of Cilostazol is 100 mg bid, taken at least half an hour before or two hours after breakfast and dinner.
A dose of 50 mg bid should be considered during coadministration of Fluconazole, Ketoconazole, Itraconazole, Erythromycin, Clarithromycin, Fluvoxamine, Fluoxetine, Nefazodone, Sertraline and Diltiazem.
Co-admin with drugs that affect CYP3A4 (erythromycin, other macrolides, diltiazem) or CYP2C19 (omeprazole) may influence the pharmacokinetics of cilostazol.
Cilostazol is contraindicated in patients with congestive heart failure of any severity. Cilostazol is also contraindicated in patients with known or suspected hypersensitivity to any of its components.
The most common side effects are headache, diarrhoea, vomiting, leg cramps, rash etc. The less frequent side effects are anorexia and edema.
Pregnancy & Lactation
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.
Precautions & Warnings
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.
Use in Special Populations
Paediatric use: The safety and effectiveness of Cilostazol in paediatric patients have not been established.
Severe headache, diarrhoea, hypotension, tachycardia, and possibly cardiac arrhythmias. Careful observation and supportive treatment are recommended.
