Mechanism of Action

Vasocil Tablet 100 mg inhibits phosphodiesterase III (PDE3), leading to increased levels of cyclic adenosine monophosphate (cAMP) in platelets and blood vessels. This results in vasodilation (widening of blood vessels) and inhibition of platelet aggregation. By preventing platelets from clumping together and improving blood flow, Vasocil Tablet 100 mg helps to alleviate the symptoms of intermittent claudication.

How Long Does It Take to Work?

The therapeutic effects of Vasocil Tablet 100 mg, particularly improvement in walking distance and reduction in symptoms of intermittent claudication, may take 2 to 4 weeks to become noticeable. However, full effects may require 12 weeks or more of consistent treatment.

Absorption

Vasocil Tablet 100 mg is rapidly absorbed after oral administration, with peak plasma concentrations occurring within 2 to 4 hours. Its absorption is enhanced by food, particularly high-fat meals, which increase drug exposure by up to 90%.

Route of Elimination

Vasocil Tablet 100 mg is metabolized extensively in the liver, primarily by cytochrome P450 enzymes (CYP3A4 and CYP2C19). The drug and its metabolites are eliminated via the urine (around 74%) and feces (around 20%).

Dosage

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.

Pediatric use: The safety and effectiveness of Cilostazol in pediatric patients have not been established.

The recommended dosage of Vasocil Tablet 100 mg for the treatment of intermittent claudication is 100 mg twice daily.
