Code CAS 50-78-2

Characteristics of Acetylsalicylic acid

White small needle crystals or light crystalline powder, odorless or with a weak odor, weakly acid taste. It is slightly soluble in water at room temperature, soluble in hot water, easily soluble in ethanol, solutions of caustic and carbonic acid.


Pharmacological action - anti-inflammatory, antipyretic, antiaggregational, analgesic.

Inhibits cyclooxygenase (COX (cyclooxygenase) -1 and COX-2) and irreversibly inhibits the cyclooxygenase pathway of arachidonic acid metabolism, blocks the synthesis of PG (PGA2, PGD2, PGF2αulf, PGE1, PGE2, etc.) and thromboxane. Reduces hyperemia, exudation, permeability of capillaries, activity of hyaluronidase, limits the energy supply of the inflammatory process by inhibiting the production of ATP (adenosine triphosphate). Affects the subcortical centers of thermoregulation and pain sensitivity. Reduction of the content of PG (mainly PGE1) in the center of thermoregulation leads to a decrease in body temperature due to the expansion of the vessels of the skin and increased sweating. The analgesic effect is due to the influence on the centers of pain sensitivity, as well as the peripheral anti-inflammatory action and the ability of salicylates to reduce the algogenic effect of bradykinin. Reduction of thromboxane A2 in platelets leads to irreversible suppression of aggregation, somewhat dilates the blood vessels. Antiaggregant effect persists for 7 days after a single dose. A number of clinical studies have shown that a significant inhibition of the adhesion of blood platelets is achieved at doses up to 30 mg. Increases the fibrinolytic activity of plasma and reduces the concentration of vitamin K-dependent clotting factors (II, VII, IX, X). Stimulates the excretion of uric acid, as its reabsorption in the tubules of the kidneys is disturbed.

After ingestion sufficiently sucked. In the presence of enteric coating (resistant to the action of gastric juice and does not allow the absorption of acetylsalicylic acid in the stomach) is absorbed in the upper part of the small intestine. During absorption, it undergoes presystemic elimination in the intestinal wall and in the liver (deacetylated). The absorbed part is very quickly hydrolyzed by special esterases, so T1 / 2 acetylsalicylic acid is no more than 15-20 minutes. In the body it circulates (75-90% in association with albumin) and is distributed in tissues as an anion of salicylic acid. Cmax is reached after about 2 hours. With proteins of the blood plasma, acetylsalicylic acid is practically not bound. When biotransformation in the liver formed metabolites, found in many tissues and urine. Excretion of salicylates is carried out mainly by active secretion in the tubules of the kidneys in unmodified form and in the form of metabolites. Excretion of unchanged substance and metabolites depends on the pH of urine (with alkalinization of urine ionization of salicylates increases, their reabsorption worsens and excretion increases significantly).

Application of Acetylsalicylic acid

CHD, the presence of several risk factors for IHD (ischemic heart disease), painless myocardial ischemia, unstable angina, myocardial infarction (to reduce the risk of repeated myocardial infarction and death after myocardial infarction), repeated transient ischemia of the brain and ischemic stroke in men, prosthetic heart valves prophylaxis and treatment of thromboembolism), balloon coronary angioplasty, and stent placement (reducing the risk of repeated stenosis and treatment of secondary coronary artery dissection), as well as with non-atherosclerotic coronary artery disease (Kawasaki disease), aortoarteritis (Takayasu's disease), valvular mitral heart defects and atrial fibrillation, mitral valve prolapse (thromboembolism prophylaxis), recurrent thromboembolism of the pulmonary artery, Dressler's syndrome, lung infarction, acute thrombophlebitis. Fever with infectious and inflammatory diseases. Pain syndrome of mild and moderate intensity of various genesis, incl. thoracic radicular syndrome, lumbago, migraine, headache, neuralgia, toothache, myalgia, arthralgia, algodismenorea. In clinical immunology and allergology, it is used in gradually increasing doses for prolonged "aspirin" desensitization and the formation of stable tolerance for NSAIDs (nonsteroidal anti-inflammatory drugs) in patients with "aspirin" asthma and "aspirin" triad.

According to indications rheumatism, rheumatic chorea, rheumatoid arthritis, infectious-allergic myocarditis, pericarditis - is currently used very rarely.


Hypersensitivity, incl. "Aspirin" triad, "aspirin" asthma; hemorrhagic diathesis (haemophilia, von Willebrand's disease, telangiectasia), exfoliating aortic aneurysm, heart failure, acute and recurrent erosive-ulcer diseases of the digestive tract, gastrointestinal bleeding, acute renal or hepatic insufficiency, initial hypoprothrombinemia, vitamin K deficiency , thrombocytopenia, thrombotic thrombocytopenic purpura, glucose-6-phosphate dehydrogenase deficiency, pregnancy (I and III trimester), breastfeeding, childhood and adolescence up to 15 years when used as an antipyretic agent (risk of developing Reye's syndrome in children with fever on the background of viral diseases).

Restrictions for use

Hyperuricemia, nephrolithiasis, gout, gastric and duodenal ulcer (in the anamnesis), severe violations of liver and kidney function, bronchial asthma, COPD, nasal polyposis, uncontrolled hypertension.

pregnancy and lactation

The use of large doses of salicylates in the first trimester of pregnancy is associated with an increased frequency of fetal development defects (cleft palate, heart defects). In the II trimester of pregnancy, salicylates can only be prescribed taking into account the risk and benefit assessment. The appointment of salicylates in the III trimester of pregnancy is contraindicated.

Salicylates and their metabolites penetrate into breast milk in small amounts. The accidental intake of salicylates during lactation is not accompanied by the development of adverse reactions in the child and does not require the cessation of breastfeeding. However, with prolonged use or administration in high doses, breast-feeding should be discontinued.

Side effects of Acetylsalicylic acid

From the cardiovascular system and blood (hematopoiesis, hemostasis): thrombocytopenia, anemia, leukopenia.

On the part of the digestive tract (gastrointestinal tract): NSAIDs (non-steroidal anti-inflammatory drugs) -gastropathy (dyspepsia, epigastric pain, heartburn, nausea and vomiting, severe bleeding in the digestive tract), decreased appetite.

Allergic reactions: hypersensitivity reactions (bronchospasm, laryngeal edema and urticaria), the formation of "aspirin" bronchial asthma and "aspirin" triad (eosinophilic rhinitis, recurrent nasal polyposis, hyperplastic sinusitis) on the basis of the hapten mechanism.

Other: impaired liver and / or kidney function, Reye's syndrome in children (encephalopathy and acute fatty liver disease with rapid development of liver failure).

With prolonged use - dizziness, headache, tinnitus, decreased hearing acuity, visual impairment, interstitial nephritis, prerenal azotemia with increased blood creatinine and hypercalcemia, papillary necrosis, acute renal failure, nephrotic syndrome, blood diseases, aseptic meningitis, enhancement symptoms of congestive heart failure, edema, increased levels of aminotransferases in the blood.


Increases the toxicity of methotrexate, reducing its renal clearance, the effects of narcotic analgesics (codeine), oral antidiabetics, heparin, indirect anticoagulants, thrombolytic agents and platelet aggregation inhibitors, reduces the effect of uricosuric drugs (benzbromarone, sulfinpyrazone), antihypertensives, diuretics spironolactone, furosemide). Paracetamol, caffeine increase the risk of side effects. Glucocorticoids, ethanol and ethanol containing drugs increase the negative effect on the mucosa of the gastrointestinal tract and increase the clearance. Increases the concentration of digoxin, barbiturates, lithium salts in plasma. Antatsida containing magnesium and / or aluminum, slow down and worsen the absorption of acetylsalicylic acid. Myelotoxic drugs increase manifestations of hematotoxicity of acetylsalicylic acid.


May occur after a single dose of a large dose or with prolonged use. If a single dose is less than 150 mg / kg, acute poisoning is considered easy, 150-300 mg / kg - moderate, with higher doses - heavy.

Symptoms: salicylism syndrome (nausea, vomiting, tinnitus, visual impairment, dizziness, severe headache, general malaise, fever - a poor prognostic sign in adults). More severe poisoning - stupor, convulsions and coma, non-cardiogenic pulmonary edema, severe dehydration, violations of the acid-base state (first - respiratory alkalosis, then - metabolic acidosis), kidney failure and shock.

In chronic overdose, the concentration in the plasma is poorly correlated with the severity of intoxication. The highest risk of developing chronic intoxication is observed in elderly people with a dose of more than 100 mg / kg / day for several days. In children and elderly patients, the initial signs of salicylism are not always noticeable, so it is advisable to periodically determine the concentration of salicylates in the blood. A level above 70 mg% indicates moderate or severe poisoning; above 100 mg% - about extremely severe, prognostically unfavorable. If moderate poisoning is required, hospitalization is necessary for at least 24 hours.

Treatment: provocation of vomiting, the appointment of activated carbon and laxatives, monitoring of KHS and electrolyte balance; depending on the state of metabolism - the introduction of sodium bicarbonate, sodium citrate solution or sodium lactate. The increase in reserve alkalinity increases the excretion of acetylsalicylic acid by alkalinizing urine. Urine alkalization is indicated at salicylate levels above 40 mg%, is provided by intravenous infusion of sodium hydrogen carbonate - 88 meq per 1 liter of 5% glucose solution, at a rate of 10-15 ml / kg / h. Recovery of bcc and induction of diuresis (achieved by the introduction of bicarbonate in the same dose and dilution, repeat 2-3 times); it should be borne in mind that intensive fluid infusion of the elderly patient can lead to pulmonary edema. It is not recommended to use acetazolamide for alkalinization of urine (can cause acidemia and enhance the toxic effect of salicylates). Hemodialysis is indicated at a salicylate level of more than 100-130 mg%, and in patients with chronic poisoning - 40 mg% and lower in the presence of indications (refractory acidosis, progressive deterioration, severe CNS damage, pulmonary edema and kidney failure). With pulmonary edema - IVL with a mixture enriched with oxygen, in the positive pressure mode at the end of exhalation; To treat edema of the brain, hyperventilation and osmotic diuresis are used.

Routes of administration


Precautions for Acetylsalicylic acid

It is undesirable to use together with other NSAIDs and glucocorticoids. For 5-7 days before surgery, it is necessary to cancel taking (to reduce bleeding during surgery and in the postoperative period).

The likelihood of developing NSAID-gastropathy decreases with the appointment after eating, using tablets with buffer additives or covered with a special enteric coating. The risk of hemorrhagic complications is considered to be the lowest when applied at doses <100 mg / day.

It should be borne in mind that in predisposed patients, acetylsalicylic acid (even in small doses) reduces the excretion of uric acid from the body and can lead to the development of an acute attack of gout.

During prolonged therapy, it is recommended to perform a regular blood test and examine the feces for latent blood. In connection with the observed cases of hepatogenic encephalopathy is not recommended for the management of febrile syndrome in children.
