Acetylsalicylic acid (ASA) more commonly known as aspirin is a painkiller that has a wide range of uses. It is frequently used to treat fever, mild pain, tooth aches, headaches and muscle aches. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) and can be used in the management of conditions such as heart attack, arthritis, blood clots and stroke. Aspirin, has been used for thousands of years, initially extracted from the leaves of willow trees.
Aspirin works in much the same way as other NSAIDs but has additional properties, such as antiplatelet activity which can make it additionally useful. More recently aspirin has been linked with cancer prevention. But the potential benefits of aspirin need to be weighed against the potential side effects, which includes gastrointestinal bleeding and Reye’s syndrome. It should be noted that aspirin should not be used in people who are allergic to drugs such as ibuprofen or a more generalized intolerance to NSAIDs. It should also be used cautiously in asthmatics and/or those with bronchospasm associated with NSAID use.

Aspirin reduces a woman’s chance of developing pre-eclampsia in pregnancy NIHR DC | Signal - Aspirin reduces a woman’s chance of developing pre-eclampsia in pregnancy Dissemination Centre Discover Portal NIHR DC Discover NIHR Signal Aspirin reduces a woman’s chance of developing pre-eclampsia in pregnancy Published on 31 October 2017 Giving low dose aspirin to high-risk women reduced their risk of pre-eclampsia before 37 weeks of pregnancy. Preterm pre-eclampsia developed in 1.6% of women given (...) 150mg aspirin daily compared with 4.3% who took a placebo. Pre-eclampsia is a condition which can harm mother and baby. In the mother, it causes high blood pressure and protein in the urine, which can show in pregnancy after 20 weeks. Women with risk factors, such as previous pre-eclampsia, diabetes or high blood pressure, are often prescribed 75mg aspirin from 12 weeks onwards. This study aimed to test double this dose (still classified as a `low dose’) after using a new risk assessment

We evaluated aspirin and non-aspirin NSAID use and risk of pancreatic adenocarcinoma in 141,940 participants from the Health Professionals Follow-up Study and Nurses' Health Study using multivariable-adjusted Cox proportional hazards regression. We considered several exposure classifications to model differing lag times between NSAID
Aspirin or Rivaroxaban for VTE Prophylaxis after Hip or Knee Arthroplasty. BACKGROUND: Clinical trials and meta-analyses have suggested that aspirin may be effective for the prevention of venous thromboembolism (proximal deep-vein thrombosis or pulmonary embolism) after total hip or total knee arthroplasty, but comparisons with direct oral anticoagulants are lacking for prophylaxis beyond hospital discharge. METHODS: We performed a multicenter, double-blind, randomized, controlled trial (...) involving patients who were undergoing total hip or knee arthroplasty. All the patients received once-daily oral rivaroxaban (10 mg) until postoperative day 5 and then were randomly assigned to continue rivaroxaban or switch to aspirin (81 mg daily) for an additional 9 days after total knee arthroplasty or for 30 days after total hip arthroplasty. Patients were followed for 90 days for symptomatic venous thromboembolism (the primary effectiveness outcome) and bleeding complications, including major

Antiplatelet therapy with aspirin, clopidogrel, and dipyridamole versus clopidogrel alone or aspirin and dipyridamole in patients with acute cerebral ischaemia (TARDIS): a randomised, open-label, phase 3 superiority trial. BACKGROUND: Intensive antiplatelet therapy with three agents might be more effective than guideline treatment for preventing recurrent events in patients with acute cerebral ischaemia. We aimed to compare the safety and efficacy of intensive antiplatelet therapy (combined (...) aspirin, clopidogrel, and dipyridamole) with that of guideline-based antiplatelet therapy. METHODS: We did an international, prospective, randomised, open-label, blinded-endpoint trial in adult participants with ischaemic stroke or transient ischaemic attack (TIA) within 48 h of onset. Participants were assigned in a 1:1 ratio using computer randomisation to receive loading doses and then 30 days of intensive antiplatelet therapy (combined aspirin 75 mg, clopidogrel 75 mg, and dipyridamole 200 mg
Should This Patient Receive Aspirin?: Grand Rounds Discussion From Beth Israel Deaconess Medical Center. Aspirin exerts antiplatelet effects through irreversible inhibition of cyclooxygenase-1, whereas its anticancer effects may be due to inhibition of cyclooxygenase-2 and other pathways. In 2009, the U.S. Preventive Services Task Force endorsed aspirin for primary prevention of cardiovascular disease. However, aspirin's role in cancer prevention is still emerging, and no groups currently (...) recommend its use for this purpose. To help physicians balance the benefits and harms of aspirin in primary disease prevention, the Task Force issued a guideline titled, "Aspirin Use for the Primary Prevention of Cardiovascular Disease and Colorectal Cancer" in 2016. In the evidence review conducted for the guideline, cardiovascular disease mortality and colorectal cancer mortality were significantly reduced among persons taking aspirin. However, there was no difference in nonfatal stroke

Rivaroxaban with or without Aspirin in Stable Cardiovascular Disease. Background We evaluated whether rivaroxaban alone or in combination with aspirin would be more effective than aspirin alone for secondary cardiovascular prevention. Methods In this double-blind trial, we randomly assigned 27,395 participants with stable atherosclerotic vascular disease to receive rivaroxaban (2.5 mg twice daily) plus aspirin (100 mg once daily), rivaroxaban (5 mg twice daily), or aspirin (100 mg once daily (...) ). The primary outcome was a composite of cardiovascular death, stroke, or myocardial infarction. The study was stopped for superiority of the rivaroxaban-plus-aspirin group after a mean follow-up of 23 months. Results The primary outcome occurred in fewer patients in the rivaroxaban-plus-aspirin group than in the aspirin-alone group (379 patients [4.1%] vs. 496 patients [5.4%]; hazard ratio, 0.76; 95% confidence interval [CI], 0.66 to 0.86; P<0.001; z=-4.126), but major bleeding events occurred in more
Aspirin versus Placebo in Pregnancies at High Risk for Preterm Preeclampsia. Background Preterm preeclampsia is an important cause of maternal and perinatal death and complications. It is uncertain whether the intake of low-dose aspirin during pregnancy reduces the risk of preterm preeclampsia. Methods In this multicenter, double-blind, placebo-controlled trial, we randomly assigned 1776 women with singleton pregnancies who were at high risk for preterm preeclampsia to receive aspirin, at (...) a dose of 150 mg per day, or placebo from 11 to 14 weeks of gestation until 36 weeks of gestation. The primary outcome was delivery with preeclampsia before 37 weeks of gestation. The analysis was performed according to the intention-to-treat principle. Results A total of 152 women withdrew consent during the trial, and 4 were lost to follow up, which left 798 participants in the aspirin group and 822 in the placebo group. Preterm preeclampsia occurred in 13 participants (1.6%) in the aspirin group
Rivaroxaban or Aspirin for Extended Treatment of Venous Thromboembolism. Background Although many patients with venous thromboembolism require extended treatment, it is uncertain whether it is better to use full- or lower-intensity anticoagulation therapy or aspirin. Methods In this randomized, double-blind, phase 3 study, we assigned 3396 patients with venous thromboembolism to receive either once-daily rivaroxaban (at doses of 20 mg or 10 mg) or 100 mg of aspirin. All the study patients had (...) (1.5%) receiving 20 mg of rivaroxaban and in 13 of 1127 patients (1.2%) receiving 10 mg of rivaroxaban, as compared with 50 of 1131 patients (4.4%) receiving aspirin (hazard ratio for 20 mg of rivaroxaban vs. aspirin, 0.34; 95% confidence interval [CI], 0.20 to 0.59; hazard ratio for 10 mg of rivaroxaban vs. aspirin, 0.26; 95% CI, 0.14 to 0.47; P<0.001 for both comparisons). Rates of major bleeding were 0.5% in the group receiving 20 mg of rivaroxaban, 0.4% in the group receiving 10 mg
