Pletal is a brand-name medication that contains the active ingredient cilostazol. It is supplied as an oral pill in strengths of 50 mg and 100 mg. Cilostazol belongs to the Heart & Blood Pressure therapeutic class and works by inhibiting phosphodiesterase III, which leads to vasodilation and inhibition of platelet aggregation. In Hong Kong, Pletal is a prescription-only product regulated by the Department of Health’s Pharmaceutical Division.
Cilostazol blocks the enzyme phosphodiesterase III (PDE3). This action raises intracellular cyclic adenosine monophosphate (cAMP) levels in vascular smooth-muscle cells and platelets.
The combined vasodilatory and antiplatelet effects help relieve symptoms of reduced peripheral circulation, particularly in the legs. Onset of action typically occurs within a few hours after the first dose, with peak plasma concentrations reached in about 2-4 hours. The drug’s half-life is roughly 11-13 hours, supporting twice-daily dosing.
Pletal is approved in Hong Kong (as in many other jurisdictions) for the treatment of intermittent claudication-painful cramping in the calf muscles that occurs during walking because of peripheral arterial disease (PAD). It is intended for adult patients who have stable PAD and can benefit from improved walking distance and reduced leg pain.
If any of the above conditions apply, patients should discuss alternative therapies with their healthcare provider.
These effects are generally self-limiting; staying well hydrated and taking the medication with food can help reduce gastrointestinal upset.
If a patient experiences sudden bruising, blood in stools or urine, severe chest pain, or fainting, they should seek immediate medical attention.
Patients should provide a complete medication list, including over-the-counter drugs, herbal supplements, and vitamins, to their prescriber.

Cilostazol is best absorbed when taken with food. Taking it on an empty stomach may increase gastrointestinal discomfort and reduce absorption efficiency.
Most patients report a modest increase in walking distance after 2-4 weeks of consistent therapy, though individual response varies.
Mild to moderate renal impairment does not usually require dose adjustment, but severe kidney disease warrants careful monitoring and may limit use.
Cilostazol does not have a direct pharmacokinetic interaction with nitroglycerin, but both affect blood vessels; patients should monitor for excessive dizziness or low blood pressure.
Take the missed dose as soon as you remember unless it is close to the time for your next scheduled dose. In that case, skip the missed dose and continue with the regular schedule; do not double the dose.
Yes, but keep the medication in its original labeled container, carry a copy of the prescription, and be aware of any import restrictions that Hong Kong or the destination country may have for prescription drugs.
Regular, supervised walking exercise, smoking cessation, and a heart-healthy diet can synergistically improve peripheral circulation and augment the benefits of cilostazol.
Cilostazol has not been shown to have a clinically significant impact on glucose metabolism, but patients with diabetes should continue routine monitoring.
Yes, cilostazol is also marketed as a generic product in Hong Kong. The active ingredient and dosage strengths are identical, though brand names may differ.
Do not flush tablets down the toilet. Use a pharmacy’s medication-take-back program or follow Hong Kong’s guidelines for safe disposal of pharmaceutical waste.
