Huazi found that many people do not understand the pharmacological effects of aspirin, when taking, there are many people who take the initiative without authorization, some people do not use the drug standard, and can not play a role in preventing blood clots, just eat a lonely; there are some people, do not need to take aspirin, but follow the trend of taking medicine, resulting in excessive treatment, the result did not enjoy the benefits of aspirin, only in vain suffered the side effects of the drug.
Aspirin is a drug not a health supplement, has strict indications and requirements for taking, and cannot be taken arbitrarily.
First, a hundred years of "magic medicine" aspirin
Aspirin has been invented for more than a hundred years and has been dubbed the "miracle drug". High-dose aspirin has antipyretic, analgesic, anti-inflammatory effects, and is used in the treatment of fever, pain, and rheumatism.
Later, it was found that aspirin also inhibits platelet aggregation and can prevent the formation of blood clots in the arteries, so now aspirin mainly uses its small dose dosage form to prevent the occurrence of thrombotic diseases.
However, drug treatment is a "double-edged sword", and while enjoying the benefits of drugs, it is also necessary to bear the risk of adverse drug reactions. Therefore, when using aspirin, there are strict indication requirements.
Second, what kind of people need to use aspirin
Aspirin can inhibit the aggregation of platelets, but under normal circumstances, platelets do not aggregate within blood vessels, and in general, platelet aggregation is activated only when atherosclerosis occurs and the hardening plaque rupture occurs.
That is, if there is no atherosclerosis, or when the risk of cracking of hardened plaque is small, taking aspirin has no preventive effect. Long-term use of aspirin has the risk of bleeding diseases, as well as adverse reactions to damage to the mucosa of the digestive tract, and the pros and cons must be weighed before taking the drug.
Relevant trials have shown that for people who have not experienced cardiovascular and cerebrovascular diseases, the benefits of taking aspirin will be offset by the risks taken, so it is not recommended that healthy people take aspirin to prevent the occurrence of disease and avoid the risk of medication caused by overtreatment.
But for people who have already had myocardial infarction, cerebral infarction and other thrombotic diseases, the risk of recurrence of the disease is very high, and the benefits of taking aspirin will be greater, so now aspirin is only recommended for people who have suffered from cardiovascular and cerebrovascular diseases to prevent disease recurrence, or after medical evaluation, the probability of cardiovascular and cerebrovascular diseases in the next 10 years is greater than 10%.
Third, how to take aspirin correctly
Aspirin works by inhibiting platelets, and platelets in the human body are renewed every day, so aspirin needs to be taken every day to inhibit newly formed platelets in order to continue to play a disease prevention role.
Used to prevent cardiovascular and cerebrovascular diseases is a small dose of aspirin, "small dose" refers to the daily use of between 75 mg and 150 mg.
Relevant trials have shown that if the dose of aspirin is reduced to less than 50 mg per day, the effect of inhibiting all platelets is not achieved. When taken daily at doses greater than 150 mg, the efficacy does not increase, but the side effects increase significantly. The most commonly used dose of aspirin is 100 mg per day.
That is to say, it is necessary to insist on taking an effective dose of aspirin regularly every day in order to play a preventive role, otherwise it will only eat a "lonely".
To sum up, people who have not had cardiovascular and cerebrovascular diseases are not recommended to take aspirin. People who have had related diseases and need to prevent recurrence of the disease need to insist on taking an effective dose of aspirin every day in order to effectively prevent the disease. Medications should be taken under the guidance of a doctor, and if you have any doubts about medication, please consult a doctor or pharmacist.
