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.

Pain 614 Sources: https://www.accessdata.fda.gov/drugsatfda_docs/label/2016/011483s029lbl.pdf	Primary	Approved 8429	SYNALGOS-DC Approved Use SYNALGOS-DC is a combination of dihydrocodeine, an opioid agonist, aspirin, a nonsteroidal anti-inflammatory drug, and caffeine, a methylxanthine, and is indicated for the management of pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. Launch Date 1958
Headache 47 Sources: https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=a00c6776-e9ef-411b-9396-915c3787559a	Primary	Approved 8429	FIORINAL Approved Use FIORINAL is indicated for the relief of the symptom complex of tension (or muscle contraction) headache. Evidence supporting the efficacy and safety of Fiorinal in the treatment of multiple recurrent headaches is unavailable. Caution in this regard is required because butalbital is habit-forming and potentially abusable. Launch Date 1976
Myocardial infarction 121 Sources: https://www.accessdata.fda.gov/drugsatfda_docs/label/2015/200671s000lbl.pdf	Preventing	Approved 8429	DURLAZA Approved Use DURLAZA is a nonsteroidal anti-inflammatory drug indicated to reduce the risk of death and myocardial infarction (MI) in patients with chronic coronary artery disease, such as patients with a history of MI or unstable angina pectoris or with chronic stable angina and to reduce the risk of death and recurrent stroke in patients who have had an ischemic stroke or transient ischemic attack. Launch Date 2015
Stroke 144 Sources: https://www.accessdata.fda.gov/drugsatfda_docs/nda/99/20884_AGGRENOX_prntlbl.pdf	Preventing	Approved 8429	AGGRENOX Approved Use AGGRENOX is indicated to reduce the risk of stroke in patients who have had transient ischemia of the brain or completed ischemic stroke due to thrombosis.

Sample Use Guides

In Vivo Use Guide

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

In Vitro Use Guide

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.
