If you’ve been prescribed Pletal for leg pain caused by peripheral artery disease (PAD), you might be wondering whether there’s a better or cheaper option. Below we break down how Pletal stacks up against the most common alternatives, so you can decide what fits your health goals and budget.
Quick Takeaways
- Pletal (cilostazol) improves walking distance by 30‑40% in most patients with intermittent claudication.
- Pentoxifylline offers modest benefit (10‑15%) and is cheaper, but has more gastrointestinal side effects.
- Aspirin and clopidogrel prevent cardiovascular events but do little for walking performance.
- Statins (e.g., atorvastatin) target the disease cause; they don’t directly relieve claudication but improve overall outcomes.
- Supervised exercise remains the most cost‑effective, non‑drug therapy, increasing walking distance by up to 50%.
What is Pletal (Cilostazol)?
Cilostazol is the active ingredient in the brand‑name drug Pletal. It belongs to the phosphodiesterase‑3 inhibitor class and works by widening blood vessels and preventing platelet clumping. Approved by the FDA and TGA for intermittent claudication, typical dosing is 100mg twice daily.
Why Look for Alternatives?
Not everyone tolerates cilostazol well. Common side effects include headache, diarrhea, and palpitations. Some patients have contraindications such as heart failure or recent stroke. Cost can also be an issue, especially without private health cover. These factors drive the search for other drugs or non‑pharmacologic options.
Key Alternatives Overview
Below are the six most frequently considered options. Each entry includes a brief definition with microdata markup for the first mention.
Pentoxifylline is a methylxanthine derivative that improves red blood cell flexibility and reduces blood viscosity. It’s used off‑label for intermittent claudication, usually at 400mg three times daily.
Aspirin (acetylsalicylic acid) is an antiplatelet agent that irreversibly inhibits cyclooxygenase‑1, reducing clot formation. Standard dose for PAD prevention is 81‑325mg once daily.
Clopidogrel is a thienopyridine antiplatelet drug that blocks the ADP receptor on platelets. The usual dose for cardiovascular protection is 75mg daily.
Atorvastatin is a HMG‑CoA reductase inhibitor (statin) that lowers LDL cholesterol and stabilizes atherosclerotic plaques. Dosage ranges from 10‑80mg nightly, depending on risk profile.
Supervised Exercise Therapy (SET) involves structured walking sessions on a treadmill or track, typically three times a week for 12 weeks. It improves collateral circulation without drugs.
Intermittent Claudication describes the leg pain that appears during exertion and eases with rest, caused by reduced blood flow in peripheral arteries.
Comparison Table
| Drug / Therapy | Mechanism | FDA/TGA Status | Typical Dose | Improvement in Walking Distance | Common Side Effects | Approx. Monthly Cost (AU$) |
|---|---|---|---|---|---|---|
| Pletal (Cilostazol) | Phosphodiesterase‑3 inhibition → vasodilation & anti‑platelet | Approved for claudication | 100mg BID | 30‑40% increase | Headache, diarrhea, palpitations | ~$120 |
| Pentoxifylline | Rheologic agent → improves RBC flexibility | Off‑label for PAD | 400mg TID | 10‑15% increase | Nausea, dizziness, rash | ~$30 |
| Aspirin | Irreversible COX‑1 inhibition → antiplatelet | Approved for cardiovascular prophylaxis | 81‑325mg QD | ~0% (does not improve walking) | GI irritation, bleeding | ~$5 |
| Clopidogrel | ADP‑P2Y12 receptor blockade → antiplatelet | Approved for stroke/TIA prevention | 75mg QD | ~0% (no walking benefit) | Bruising, GI upset | ~$25 |
| Atorvastatin | HMG‑CoA reductase inhibition → lipid lowering | Approved for hyperlipidaemia | 10‑80mg nightly | ~0% (does not directly improve walking) | Myalgia, liver enzyme rise | ~$15 |
| Supervised Exercise Therapy | Improves collateral circulation & muscle efficiency | Guideline‑recommended non‑drug therapy | 3 sessions/week, 30‑45min each | 30‑50% increase | None (except occasional fatigue) | ~$100 (program fee) |
Decision Criteria - How to Pick the Right Option
When comparing Pletal to its alternatives, consider these four factors:
- Efficacy for walking distance. If your primary goal is to walk farther, look at the percentage improvement column.
- Safety profile. Heart failure patients should avoid cilostazol; those with bleeding risk should steer clear of aspirin or clopidogrel.
- Cost and insurance coverage. In Australia, the Pharmaceutical Benefits Scheme (PBS) subsidises Pletal for certain patients, but not all alternatives are covered.
- Convenience and adherence. Twice‑daily pills may be easier than three‑times‑daily regimens, while exercise requires time commitment.
Best‑Fit Scenarios
Choose Pletal if: you have mild‑to‑moderate claudication, no heart failure, and can afford the PBS‑supported price.
Consider Pentoxifylline when: cost is a major barrier and you can tolerate a TID schedule.
Aspirin or Clopidogrel are right for: patients primarily needing cardiovascular event prevention rather than symptom relief.
Statins (e.g., Atorvastatin) are essential for: anyone with dyslipidaemia or high atherosclerotic risk, regardless of claudication severity.
Supervised Exercise Therapy is ideal if: you want the biggest functional gain without adding drugs, and you have access to a vascular rehab centre.
Potential Pitfalls and How to Avoid Them
- Missing contraindications. Cilostazol is contraindicated in NYHA Class III/IV heart failure - double‑check your cardiac status.
- Assuming side effects are harmless. Persistent headache or diarrhea may signal dosage intolerance; a dose reduction or switch to pentoxifylline can help.
- Ignoring drug interactions. Cilostazol interacts with strong CYP3A4 inhibitors (e.g., clarithromycin). Notify your clinician about all meds.
- Relying only on medication. Combining a modest drug effect with weekly exercise often yields the best overall outcome.
How to Switch Safely
If you decide to move away from Pletal, follow these steps:
- Consult your vascular specialist or GP to confirm the new regimen aligns with your comorbidities.
- Gradually taper the cilostazol dose over 3‑5 days to reduce rebound platelet activity.
- Start the alternative (e.g., pentoxifylline) at the lowest effective dose and monitor for side effects.
- Schedule a follow‑up walk test after 4-6 weeks to assess improvement.
Bottom Line
Pletal remains a strong first‑line drug for improving walking distance in PAD, but it isn’t the only game in town. Alternatives like pentoxifylline offer cheaper, albeit weaker, benefits, while antiplatelet agents protect the heart without touching claudication symptoms. For many patients, a blend of medication, statin therapy, and supervised exercise delivers the best overall health picture.
Frequently Asked Questions
Can I take Pletal with aspirin?
Yes, many clinicians prescribe low‑dose aspirin alongside cilostazol for broader cardiovascular protection. However, monitor for increased bleeding risk, especially if you have a gastric ulcer history.
Why does Pletal not work for people with heart failure?
Cilostazol can increase heart rate and contractility via phosphodiesterase‑3 inhibition, which may worsen symptoms in advanced heart failure. This safety warning is backed by multiple clinical trials showing higher mortality in that subgroup.
Is pentoxifylline covered by the PBS?
Currently, pentoxifylline is not listed on the PBS for PAD, so patients pay the full price out‑of‑pocket unless they have private insurance that includes it.
How long does it take to see improvement with Pletal?
Most studies report a measurable increase in maximal walking distance after 8-12 weeks of consistent use, provided the dose is maintained and no major side effects force discontinuation.
Should I stop Pletal before surgery?
Yes, stop cilostazol at least 48 hours before any elective surgery to reduce bleeding risk. Inform your surgeon and anaesthetist about the medication history.

While the comparative table is impressively thorough, one might be tempted to elevate the discourse by pondering the pharmacoeconomic implications of cilostazol in a truly global context. The nuanced interplay between efficacy and affordability warrants a sophisticated appreciation, especially when juxtaposing Pletal against the modest gains of pentoxifylline. Moreover, the subtle cardiovascular safeguards offered by antiplatelet agents could be more eloquently integrated into the decision matrix. All in all, a commendable foundation, yet there remains room for a more erudite synthesis.
