Description
Phasostabil Pharmacodynamics
The mechanism of action of acetylsalicylic acid (ASA) is based on irreversible inhibition of cyclooxygenase (COX-1), which blocks the synthesis of thromboxane A2 and inhibits platelet aggregation. It is believed that ASA has other mechanisms to inhibit platelet aggregation, which expands the field of its use in various vascular diseases. ASA also has anti-inflammatory, analgesic, and antipyretic effects. The anti-inflammatory effect is associated with a decrease in blood flow due to inhibition of prostaglandin E2 synthesis.
Magnesium hydroxide, which is part of the drug Fazostabil, has an antacid effect and protects the mucous membrane of the gastrointestinal tract from the effects of ASA.
Indications
– Primary prevention of cardiovascular diseases, such as thrombosis and acute heart failure in the presence of risk factors (e.g. diabetes mellitus, hyperlipidemia, arterial hypertension, obesity, smoking, old age);
– Prevention of recurrent myocardial infarction and blood vessel thrombosis;
– Prevention of thromboembolism after vascular surgery (coronary artery bypass grafting, percutaneous transluminal coronary angioplasty);
– unstable angina pectoris.
Contraindications
– Hypersensitivity to ASA, excipients of the drug and other nonsteroidal anti-inflammatory drugs (NSAIDs);
– cerebral hemorrhage;
– susceptibility to bleeding (vitamin K insufficiency, thrombocytopenia, hemorrhagic diathesis);
– chronic heart failure functional class III-IV according to NYHA classification;
– Bronchial asthma induced by taking salicylates and NSAIDs;
– complete or incomplete combination of bronchial asthma, recurrent nasal and paranasal sinus polyposis, and intolerance to ASA or other NSAIDs, including cyclooxygenase-2 (COX-2) inhibitors (including history);
– gastrointestinal erosive and ulcerative lesions (acute phase);
– gastrointestinal bleeding;
– severe renal insufficiency (creatinine clearance (CK) less than 30 ml/min);
– hepatic insufficiency (class B and C according to the Child-Pugh classification);
– pregnancy (I and III trimesters), breastfeeding;
– Glucose-6-phosphate dehydrogenase deficiency;
– concomitant use with methotrexate (more than 15 mg per week);
