What is Aspirin?

Aspirin is a salicylate (sa-LIS-il-ate). It works by reducing substances in the body that cause pain, fever, and inflammation.

Aspirin is used to treat pain, and reduce fever or inflammation. Aspirin is sometimes used to treat or prevent heart attacks, strokes, and chest pain (angina). Aspirin should be used for cardiovascular conditions only under the supervision of a doctor.

Aspirin may also be used for purposes not listed in this medication guide.

Aspirin indications

An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

How should I use Aspirin?

Use Aspirin as directed by your doctor. Check the label on the medicine for exact dosing instructions.

Ask your health care provider any questions you may have about how to use Aspirin.

Uses of Aspirin in details

There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.

Use: Labeled Indications

Immediate release:

Analgesic, antipyretic, and anti-inflammatory: For the temporary relief of headache, pain, and fever caused by colds, muscle aches and pains, menstrual pain, toothache pain, and minor aches and pains of arthritis.

Revascularization procedures: For use in patients who have undergone revascularization procedures (ie, coronary artery bypass graft, percutaneous transluminal coronary angioplasty, or carotid endarterectomy).

Vascular indications, including ischemic stroke, transient ischemic attack, acute coronary syndromes (ST-elevation myocardial infarction or non-ST-elevation acute coronary syndromes [non-ST-elevation myocardial infarction or unstable angina]), secondary prevention after acute coronary syndromes, and management of stable ischemic heart disease: To reduce the combined risk of death and nonfatal stroke in patients who have had ischemic stroke or transient ischemia of the brain due to fibrin platelet emboli; to reduce the risk of vascular mortality in patients with a suspected acute myocardial infarction (MI); to reduce the combined risk of death and nonfatal MI in patients with a previous MI or unstable angina; to reduce the combined risk of MI and sudden death in patients with stable ischemic heart disease.

ER capsules:

Ischemic stroke or transient ischemic attack: To reduce the risk of death and recurrent stroke in patients who have had an ischemic stroke or transient ischemic attack.

Stable ischemic heart disease: To reduce the risk of death and MI in patients with stable ischemic heart disease.

Limitations of use: Do not use ER capsules in situations for which a rapid onset of action is required (such as acute treatment of MI or before percutaneous coronary intervention); use IR formulations instead.

Off Label Uses

Atherosclerotic cardiovascular disease, primary prevention

Based on the 2019 American College of Cardiology/American Heart Association (ACC/AHA) guideline on the primary prevention of cardiovascular disease and the 2020 American Diabetes Association standards of medical care in diabetes, Aspirin may be used for the primary prevention of cardiovascular disease in select patients after weighing the cardiovascular disease risk versus benefits.

Carotid artery atherosclerosis, asymptomatic or symptomatic

Based on the 2012 American College of Chest Physicians (ACCP) guidelines for antithrombotic therapy and prevention of thrombosis (9th edition), daily Aspirin is suggested in patients with asymptomatic or symptomatic carotid artery atherosclerosis based on a slight reduction in total mortality observed when Aspirin is taken over 10 years (regardless of cardiovascular risk profile). The AHA/American Stroke Association guidelines for the primary prevention of stroke recommend daily Aspirin for patients with asymptomatic or symptomatic carotid atherosclerosis to reduce the risk of a first stroke.

Carotid artery stenting

A randomized, controlled trial with blinded end point adjudication evaluated carotid artery stenting versus carotid endarterectomy in patients with carotid artery stenosis. In this trial, Aspirin in combination with clopidogrel was used for patients who underwent carotid artery stenting, which suggests that this antiplatelet combination is effective.

Aspirin description

sponsored

The prototypical analgesic used in the treatment of mild to moderate pain. It has anti-inflammatory and antipyretic properties and acts as an inhibitor of cyclooxygenase which results in the inhibition of the biosynthesis of prostaglandins. Aspirin also inhibits platelet aggregation and is used in the prevention of arterial and venous thrombosis. (From Martindale, The Extra Pharmacopoeia, 30th ed, p5)

Note: Ibuprofen, naproxen, and possibly other nonselective nonsteroidal anti-inflammatory drugs (NSAIDs) may reduce the cardioprotective effects of Aspirin (Capone 2005; Catella-Lawson 2001; MacDonald 2003). Avoid regular or frequent use of NSAIDs in patients receiving Aspirin for cardiovascular protection. An ER formulation exists (162.5 mg capsule); however, it should not be used in situations when a rapid onset of action is necessary (eg, ST-elevation myocardial infarction [MI]); dosing information provided is based on the IR formulations.

Analgesic and antipyretic: Immediate release:

Oral: 325 mg to 1 g every 4 to 6 hours as needed; usual maximum daily dose: 4 g/day (Abramson 2019). Note: If patient cannot take orally, rectal suppositories (300 or 600 mg) are available.

Anti-inflammatory for arthritis associated with rheumatic disease: Immediate release:

Oral: 4 to 8 g/day in 4 to 5 divided doses as needed; titrate dose based on response and tolerability. Continue treatment until symptoms resolve (typically 1 to 2 weeks, but potentially up to 8 weeks). Use of Aspirin at these high doses (4 to 8 g/day) may be limited by adverse effects (tinnitus, diminished auditory acuity, GI intolerance) (Abramson 2019; Carapetis 2012; Steer 2019).

Atherosclerotic cardiovascular disease:

Acute coronary syndrome: Note: For rapid onset, non-enteric-coated IR tablet(s) should be chewed and swallowed upon identification of clinical and ECG findings suggesting an acute coronary syndrome. Enteric-coated Aspirin is not preferred since onset of action may be delayed. If it is the only product available, enteric-coated IR tablet(s) may be chewed and swallowed (ACCP [Eikelboom 2012]; Sai 2011). For maintenance therapy, any oral formulation is acceptable for use.

Non–ST-elevation acute coronary syndromes or ST-elevation myocardial infarction: Note: For initial therapy, administer Aspirin in combination with an IV anticoagulant and a P2Y12 inhibitor (ACC/AHA [Amsterdam 2014]; ACCF/AHA [O'Gara 2013]).

Initial:

Immediate release (non-enteric-coated):

Oral: 162 to 325 mg administered once (chew and swallow) at the time of diagnosis (ACC/AHA [Amsterdam 2014]; ACCF/AHA [O'Gara 2013]).

Rectal (alternative route): 600 mg administered once at the time of diagnosis if an IR oral formulation is unavailable or oral route is not feasible (Maalouf 2009).

Maintenance (secondary prevention): Immediate release:

Oral: 75 to 100 mg once daily (ACC/AHA [Levine 2016]; Hennekens 2019; Mehta 2001).

Duration of therapy: Aspirin plus a P2Y12 inhibitor (dual antiplatelet therapy [DAPT]) should be continued for ≥12 months unless bleeding risk is a concern. If there have been no major bleeding complications after 12 months, continuation of DAPT may be considered. Re-evaluate the need for DAPT at regular intervals based on bleeding and thrombotic risks. When DAPT is complete, discontinue the P2Y12 inhibitor and continue Aspirin indefinitely (ACC/AHA [Levine 2016]; Bonaca 2015; Cutlip 2019a; Lincoff 2019; Mauri 2014; Mehta 2001; Wallentin 2009; Wiviott 2007; Yusuf 2001).

Percutaneous coronary intervention for stable ischemic heart disease (off-label use):

Initial: Note: For initial therapy, non-enteric-coated IR tablet(s) should be administered. Enteric-coated Aspirin is not preferred since onset of action is delayed. For patients who receive a coronary stent during percutaneous coronary intervention, administer Aspirin in combination with an IV anticoagulant and clopidogrel (ACCF/AHA/SCAI [Levine 2011]).

Patients chronically taking Aspirin ≥325 mg/day prior to percutaneous coronary intervention: Immediate release (non-enteric-coated):

Oral: 75 to 100 mg prior to the procedure (Cutlip 2020); some experts recommend doses up to 325 mg (ACCF/AHA/SCAI [Levine 2011]).

Patients not chronically taking Aspirin or chronically taking Aspirin <325 mg/day prior to percutaneous coronary intervention: Immediate release (non-enteric-coated):

Oral: 300 to 325 mg given ≥2 hours (preferably 24 hours) before the procedure (ACCF/AHA/SCAI [Levine 2011]; Cutlip 2020).

Maintenance: Immediate release:

Oral: 75 to 100 mg once daily in combination with clopidogrel (DAPT); upon completion of the recommended duration of DAPT, continue Aspirin indefinitely (ACC/AHA [Levine 2016]; Cutlip 2019c). Refer to Clopidogrel monograph for information on duration of DAPT.

Atherosclerotic cardiovascular disease, primary prevention (off-label use): Note: Use should be a shared decision between health care professionals and patients after weighing the cardiovascular disease risk versus benefits (ACC/AHA [Arnett 2019]).

Immediate release:

Oral: 75 to 100 mg once daily (ACC/AHA [Arnett 2019]).

Atherosclerotic cardiovascular disease, secondary prevention:

Carotid artery atherosclerosis, asymptomatic or symptomatic (off-label use): Immediate release:

Oral: 75 to 325 mg once daily (ACCP [Alonso-Coello 2012]; Walker 1995).

Coronary artery bypass graft surgery: Immediate release:

Oral: 75 to 81 mg once daily beginning preoperatively; continue indefinitely following surgery (AHA [Kulik 2015]; Aranki 2019).

Off-pump coronary artery bypass graft surgery: Following surgery, consider adding clopidogrel in combination with Aspirin for 12 months then discontinue clopidogrel and continue Aspirin indefinitely (AHA [Kulik 2015]).

Patients with acute coronary syndrome followed by coronary artery bypass graft surgery: Administer Aspirin in combination with a P2Y12 inhibitor for 12 months then continue Aspirin indefinitely (AHA [Kulik 2015]). Some experts do not use P2Y12 inhibitors postoperatively in these patients (Aranki 2019).

Ischemic stroke/Transient ischemic attack:

Cardioembolic stroke (alternative agent): Note:

Oral anticoagulation is preferred. For patients who cannot take an oral anticoagulant, may consider Aspirin as an alternative (AHA/ASA [Kernan 2014]).

Immediate release:

Oral: 75 to 100 mg once daily (AHA/ASA [Kernan 2014]).

Intracranial atherosclerosis (50% to 99% stenosis of a major intracranial artery), secondary prevention: Immediate release:

Oral: 325 mg once daily; for patients with recent stroke or transient ischemic attack (within 30 days) may consider short-term use of clopidogrel (for 21 or 90 days depending on degree of stenosis) in combination with Aspirin (AHA/ASA [Kernan 2014]; Chimowitz 2011) followed by single-agent antiplatelet therapy with Aspirin, clopidogrel, or Aspirin/ER dipyridamole indefinitely (ACCP [Lansberg 2012]; AHA/ASA [Kernan 2014]; Cucchiara 2019).

Noncardioembolic ischemic stroke/transient ischemic attack: Note: For patients with a minor stroke (National Institutes of Health Stroke Scale score ≤3) or high-risk transient ischemic attack (ABCD/ of 81 mg tablet):

Analgesic:

Oral, rectal:

For older children and adolescents, after device closure of ASD, an additional anticoagulant may be given with Aspirin for 3 to 6 months, but the Aspirin should continue for at least 6 months (AHA [Giglia 2013]).

Ventricular assist device (VAD) placement: 1 to 5 mg/kg/dose once daily initiated within 72 hours of VAD placement; should be used with heparin (initiated between 8 to 48 hours following implantation) and with or without dipyridamole (ACCP [Monagle 2012])

Kawasaki disease: Limited data available; optimal dose not established: Note: Patients with Kawasaki disease and presenting with influenza or viral illness should not receive Aspirin; acetaminophen is suggested as an antipyretic in these patients and an alternate antiplatelet agent suggested for a minimum of 2 weeks (AHA [McCrindle 2017]).

Infants, Children, and Adolescents:

Oral:

Initial therapy (acute phase): Recommended dosing regimens vary. Use in combination with IV immune globulin (within first 10 days of symptom onset) and corticosteroids in some cases.
