Generic Name
Cilostazol (sil-oe-STAY-zol) Lq
Brand Name Pletal
Type of Drug Antiplatelet.
Prescribed For Intermittent claudication.
General Information
In intermittent claudication, leg muscles go into spasm due to reduced blood flow. This occurs when plaque buildup narrows blood vessels leading to the calf or other leg muscles. People with this condition often develop leg pain after walking only a short distance. Cilostazol prevents blood platelets from “clumping together” to begin the process of forming a blood clot, which can further obstruct arteries and worsen intermittent claudication. This drug is broken down in the liver.

?P,Ople with congestive heart failure (CHF) should not take cilostazol. Some studies indicate that long-term use of this drug may cause cardiovascular problems.

Brand Name
Aggrenox
Generic Ingredients
Dipyridamole + Aspirin
Type of Drug Antiplatelet.
Prescribed For
Prevention of recurrent stroke or transient ischemic attack (TIA)— “mini-stroke.”
General Information
Stroke is often the result of a clot blocking flow in a blood vessel supplying the brain. Aggrenox helps prevent blood clot formation by reducing the “stickiness” of platelets, blood cells that stick together to form the beginnings of all clots. In one study, Aggrenox reduced the risk of stroke by over 30% compared to placebo in people who had recently had a stroke or TIA.
Cautions and Warnings
Do not use this drug if you are allergic or sensitive to any of its ingredients or any nonsteroidal anti-inflammatory drug (NSAID). People who have asthma, nasal polyps, or chronic runny nose, are likely to be sensitive to aspirin.
The aspirin in Aggrenox can cause Reye’s syndrome, a severe reaction (vomiting, lethargy, and belligerence, and possibly worsening to coma) in children under age 16.
People with a history of stomach ulcers or stomach problems should avoid Aggrenox.
People who have angina or have had a recent heart attack should be very cautious about taking this drug. It may worsen chest pain.
People with low blood pressure, liver disease, or kidney failure should be cautious about taking this drug.
People taking Aggrenox may bleed for longer amounts of time. Those with bleeding disorders should avoid Aggrenox.
Possible Side Effects
✓ Most common: headache, upset stomach, abdominal pain, nausea, and diarrhea.
✓ Common: pain, tiredness, and vomiting.
✓ Less common: convulsions, rectal bleeding, blood in the stool, hemorrhoids, back pain, accidental injuries, stomach bleeding, feeling unwell, weakness, fainting, memory loss, arthritis, joint or muscle pain, coughing, and respiratory infection.
✓ Rare: Rare side effects can occur in almost any part of the body. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Avoid alcohol. People who take 3 or more drinks a day while using any aspirin-containing product are more likely to develop stomach ulcers or bleeding.
• Aspirin may reduce the blood-pressure-lowering effects of angiotensin-converting enzyme (ACE) inhibitor drugs, beta blockers, and diuretics.
• Combining aspirin and acetazolamide or an NSAID can cause kidney problems.
• Aspirin can increase the blood-thinning effects of anticoagulant (blood-thinning) drugs such as warfarin. Avoid this combination.
• Aspirin can increase the effects of oral antidiabetes drugs, possibly leading to low blood sugar.
• Aspirin counteracts the uric-acid-eliminating effects of probenecid and sulfinpyrazone.
• Aspirin can increase the toxic effects of anticonvulsant drugs and methotrexate.
• Dipyridamole increases the level of adenosine in the blood and may increase cardiovascular-related side effects. The adenosine dosage may need to be adjusted when these two drugs are combined.
• Dipyridamole may interfere with cholinesterase inhibitors used to treat myasthenia gravis.
Food Interactions
Aggrenox is best taken on an empty stomach but may be taken with food if it upsets your stomach.
Usual Dose
Adult: 1 capsule (200 mg of sustained-release dipyridamole and 25 mg of aspirin) morning and evening.
Child: not recommended.

Special Populations
Pregnancy/Breast-feeding: Pregnant women should avoid Aggrenox because of its aspirin content. Aspirin can cause bleeding problems in mother and fetus and result in a low-birth-weight infant. When this drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
