It is used to prevent strokes, reduce the risk of stroke in patients who have had transient ischemia of the brain or complete ischemic stroke due to thrombosis.
This is a combination of anti-platelet agents Aspirin & Dipyridamole intended for oral administration. Aspirin inhibits platelet aggregation by irreversible inhibition of platelet cyclooxygenase and thus inhibits the generation of thromboxane A2. Dipyridamole inhibits platelet aggregation by inhibiting the uptake of adenosine into platelet, which is a potent mediator of vasodilation. Dipyridamole increases local concentration of adenosine which increases cAMP (cyclic-adenosine monophosphate) level thus decreased ca++ concentration and inhibits platelet aggregation. Dipyridamole also inhibits phosphodiesterase (PDE) especially cyclic-guanosine monophosphate-PDE (cGMP-PDE), which increases cGMP produced by EDRF (endothelium-derived relaxing factor) Nitric oxide a potent vasodilator.
Aspirin 25 mg & Dipyridamole 200 mg orally twice a day
Co-administration with anticoagulants, antiplatelets or NSAIDS can increase risk of bleeding. Decreased renal function can occur with co-administration with NSAID, beta blockers and diuretics. Dipyridamole may counteract the anticholinesterase effect of cholinesterase inhibitors, thereby potentially aggravating myasthenia gravis.
Hypersensitivity: Aspirin and extended-release dipyridamole capsules are contraindicated in patients with known hypersensitivity to any of the product components. Allergy: Aspirin, USP is contraindicated in patients with known allergy to nonsteroidal anti-inflammatory drug (NSAID) products and in patients with the syndrome of asthma, rhinitis and nasal polyps. Aspirin, USP may cause severe urticaria, angioedema or bronchospasm. Reye Syndrome: Do not use aspirin, USP in children or teenagers with viral infections because of the risk of Reye syndrome.
Common side effects are Dizziness, Belly pain or heartburn, Upset stomach or throwing up, Loose stools (diarrhea), Joint pain, Feeling tired or weak, Back pain, Headaches
Because aspirin and extended-release dipyridamole capsules contain aspirin, aspirin and extended-release dipyridamole capsules can cause fetal harm when administered to a pregnant woman. Maternal aspirin use during later stages of pregnancy may cause low birth weight, increased incidence for intracranial hemorrhage in premature infants, stillbirths and neonatal death. Because of the above and because of the known effects of nonsteroidal anti-inflammatory drugs (NSAIDs) on the fetal cardiovascular system (closure of the ductus arteriosus), avoid aspirin and extended-release dipyridamole in the third trimester of pregnancy
Overdosage of this is likely to be dominated by signs and symptoms of Dipyridamole & Aspirin overdoses. Overdose of Dipyridamole shows hemodynamic effects with various symptoms such as warm feeling, flushes, sweating, restlessness, feeling of weakness, dizziness and a drop in blood pressure and tachycardia might also be observed. The sign of Aspirin overdose includes tinnitus, hyperthermia and hypovolemia. Treatment of overdose consists primarily of supporting vital functions, increasing drug elimination, correcting acid-base disturbances and gastric emptying or lavage as soon as possible after ingestion. Maintain fluid, electrolyte balance and to control the hypoglycemic condition intravenous fluid and infusion of glucose must be administered. Administration of Xanthine derivatives (e.g. aminophylline) may reverse the hemodynamic effects of Dipyridamole overdose.
Store at cool & dry place. Protect from light. Keep away from reach of children.
