Aspirin was created in the late 19th century, when the German pharmaceutical firm Bayer has acquired the rights to release the drug. Since the 20s of the last century became the most famous aspirin and anti-inflammatory painkillers. Use it today, opening new, both positive and negative characteristics.
Why not take aspirin during erosive yavzvennyh gastrointestinal disease
The mechanism of action of aspirin is associated with inhibition of the enzyme cyclooxygenase (COX), which is involved in the formation of prostaglandins - biologically active substances that increase inflammation. Today, it found that COX divided into two types - COX-1 and COX-2. These two types of enzymes are involved in the formation of various prostaglandins: using COX-2 formed prostaglandins involved in inflammation processes, and with the help of COX-1 - prostaglandins that protect the stomach lining from the adverse effects.
Aspirin and other NSAIDs all first generation suppressing effect of the COX-1 and COX-2, whereas modern NSAIDS inhibit only the action mainly COX-2 (COX-1 while also, of course, inhibited, but to a much lesser degree).
In connection with the mechanism of action of aspirin has significant side effects from the gastrointestinal tract have been removed the protective action of prostaglandins. In addition, the active substance of aspirin - acetylsalicylic acid ingestion is an irritant to the gastric mucosa. Therefore, aspirin is recommended to take after a meal, washing it down with milk.
With prolonged use of aspirin may develop "aspirin" stomach ulcers and perforation of the stomach wall and the development of overt or hidden gastrointestinal bleeding. Therefore, aspirin should not be prescribed for any erosive and ulcerative processes in the stomach or intestines.
These latest generation of NSAIDs as nimesulide
Nimesulide - promising Analgesic drug
(nimesil, nize), meloxicam (movalis) et al., have a significantly lower impact on the mucosa of the gastrointestinal tract than aspirin.
Why not take an aspirin with a propensity to bleed
The tendency to increased bleeding may occur in different diseases. But there are a number of diseases in which increased bleeding and bleeding tendency is the main symptom. These diseases are called hemorrhagic diathesis.
The mechanism of action of aspirin is associated with the suppression of thromboxane A2 formation - a substance that promotes activation of platelets and their capacity for adhesion and aggregation (sticking to the walls of blood vessels to form clusters - the basis for a blood clot). Without thromboxane platelet adhesion and aggregation decreased sharply, resulting in a decrease of blood clotting.
This property of Aspirin is widely used in modern medicine for the prevention of thrombosis increased. The tendency to form blood clots is increased in atherosclerosis, therefore, aspirin is used in coronary heart disease for the prevention of myocardial infarction
Myocardial infarction - the most formidable diagnosis
, Cerebrovascular disorders for the prevention of ischemic stroke
Stroke - a serious brain injury
and so on.
But the use of aspirin in hemorrhagic diathesis, or any other diseases involving reduced blood clotting ability is fraught with various complications.
What else have contraindications to the use of aspirin
Aspirin should not be taken at the "aspirin" asthma - bronchospasm caused by aspirin or other NSAIDs. If bronchospasm began with the appearance of aspirin, it is impossible to exclude their development while taking other NSAIDs.
Do not take aspirin in the first and third trimesters of pregnancy. In the first 12 weeks of pregnancy, aspirin (and all other NSAIDs) may cause developmental abnormalities, and in the third a threat of bleeding during childbirth. In the second trimester of pregnancy, you can take aspirin, but only for health reasons and on doctor's orders.
During feeding baby
Breastfeeding - a personal choice
breast aspirin also can not be taken, as it stands out with mother's milk. Today, I try not to prescribe aspirin to children under 15 years, as he became more and more often the cause of Reye's syndrome in children - serious liver and brain. Reye's syndrome is developed mainly on the background of viral infections in children, if the aspirin is given as a febrifuge.
Do not use aspirin together with methotrexate - cytostatic, which is a folic acid antagonist and leads to suppression of growth of malignant tumor cells. Methotrexate inhibits the formation of blood platelets, concurrent aspirin increases the risk of bleeding.
Aspirin has a lot of contraindications and side effects.
