What is the main effect of aspirin

Basic efficacy

Analgesic and antipyretic

Aspirin can relieve headache in a short time through vasodilation, and its effect on dull pain is better than that on sharp pain. Therefore, the drug can relieve mild or moderate dull pain, such as headache, toothache, neuralgia, muscle pain and menstrual pain; At the same time, it can make the hypothalamic thermoregulatory center set point increased by bacterial pyrogen return to normal level, so it can also be used for cold, influenza and other antipyretic. It can only relieve symptoms, but can not treat the cause of pain and fever, so other drugs should be used at the same time.

Anti inflammation and anti rheumatism

Aspirin is the first choice for the treatment of rheumatic fever. It can relieve fever, reduce inflammation, improve joint symptoms and reduce erythrocyte sedimentation rate, but it can not remove the basic pathological changes of rheumatism, and can not prevent heart damage and other complications. If there is obvious myocarditis, it is generally advocated to use adrenocortical hormone first. After the control of rheumatic symptoms and before the withdrawal of hormone, the drug should be added to reduce the rebound phenomenon caused by withdrawal of hormone.

Treatment of arthritis

In addition to rheumatoid arthritis, the product is also used in the treatment of rheumatoid arthritis, which can improve symptoms and create conditions for further treatment. In addition, the product can also relieve the symptoms of osteoarthritis, ankylosing spondylitis, juvenile arthritis and other non rheumatic inflammatory skeletal muscle pain.

antithrombosis

It can be used to prevent thrombosis after transient ischemic attack (TIA), myocardial infarction, atrial fibrillation, artificial heart valve, arteriovenous fistula or other operations. It can also be used to treat unstable angina pectoris.

Inhibition of platelet aggregation

Aspirin is used in high altitude mountaineering. It can inhibit the release of platelets and the aggregation of platelets.

Other effects

Alleviating mucocutaneous lymph node syndrome (Kawasaki disease)

Aspirin is used in children with Kawasaki disease to reduce inflammation and prevent intravascular thrombosis.

Fighting cancer

On August 6, 2014, British scientists evaluated and analyzed all available evidence and concluded that taking aspirin every day can reduce the risk of suffering from or dying from gastric cancer, colorectal cancer, etc. If people over the age of 50 in the UK take aspirin every day for 10 years, it may protect about 122000 people from cancer in 20 years.

But scientists also warn that aspirin can cause bleeding in the body, so doctors must be consulted before taking aspirin for a long time. Whether aspirin can be taken for a long time has been a controversial issue in the medical field.

Scientists at Queen Mary College have found that aspirin reduces deaths from bowel, stomach and esophageal cancer by 30 to 40 percent.

Aspirin also played a role in reducing the mortality of breast, prostate and lung cancer, but the effect was not so obvious.

The study also found that aspirin had to be taken for at least five years to see a positive effect.

The biggest side effects of long-term aspirin use include stomach bleeding and brain bleeding. The older you are, the more likely you are to have internal bleeding. After taking into account the side effects such as internal bleeding, the scientists who carried out the study suggested that aspirin should be taken for a long period of 10 years, but they also warned that doctors' consent should be obtained before taking aspirin.

Prevention of gastrointestinal cancer

Long term regular use of aspirin can greatly reduce the incidence of gastrointestinal cancer.
