Aspirin is a nonsteroidal anti-inflammatory drug. Aspirin is unique in this class of drugs because it irreversibly inhibits both COX-1 and COX-2 activity by acetylating a serine residue (Ser529 and Ser516, respectively) positioned in the arachidonic acid-binding channel, thus inhibiting the synthesis of prostaglandins and reducing the inflammatory response. The drug is used either alone or in combination with other compounds for the treatment of pain, headache, as well as for reducing the risk of stroke and heart attacks in patients with brain ischemia and cardiovascular diseases.

Sample Use Guides
Severe pain: Initiate treatment with two capsules (1 capsule contains 16 mg dihydrocodeine bitartrate, 356.4 mg aspirin, and 30 mg caffeine) orally every 4 hours as needed for pain. Headache: One or 2 capsules (1 capsule contains 50 mg butalbital, 325 mg aspirin and 40 mg caffeine) every 4 hours. Total daily dose should not exceed 6 capsules. Prevention of stoke and heart attacks: the recommended dose is one capsule of aspirin (162.5 mg) once daily. Take the capsules with a full glass of water at the same time each day. Prevention of stroke (in combination with dipyridamole): the recommended dose is one capsule (200 mg dipyridamole and 25 mg aspirin) given orally twice daily.
Route of Administration:
Enteral
Human platelet-rich plasma was incubated with various aspirin concentrations (10, 20, 50, 100, 200, 300, 400, 500 uM) at 37C for up to 4.5 h. Platelet aggregation and thromboxane generation were measured. Inhibition of platelet aggregation and thromboxane formation by 10 uM aspirin was maximal by 90 min. There was progressive inhibition by 3 uM aspirin during incubation for 270 min. By the end of this time there was also significant inhibition by 1 uM aspirin.
