Mechanism of action

Antispasmodic from the group of purines. Vasonit improves microcirculation and rheological properties of blood, inhibits PDE, increases the concentration of cAMP in platelets and ATP in erythrocytes with simultaneous saturation of the energy potential, which in turn leads to vasodilation, a decrease in CRPS, an increase in ASI and IOC without a significant change in heart rate. Expanding the coronary arteries, increases the delivery of oxygen to the myocardium (antianginal effect), the vessels of the lungs - improves blood oxygenation. Increases the tone of the respiratory muscles (intercostal muscles and diaphragm).

Adverse reactions

Gastrointestinal: possibly nausea, vomiting, diarrhea, dry mouth, loss of appetite, feeling of fullness in the abdomen, epigastric pain, increased activity of liver enzymes (ALT, AST, LDH) and alkaline phosphatase, cholecystitis, hepatitis, jaundice; rarely - an unpleasant taste in the mouth, hypersalivation.
From the side of the central nervous system: relatively rarely - headache, dizziness, anxiety, sleep disturbances, convulsions.
Special senses: rarely - conjunctivitis, scotoma, blurred vision, earache.
Cardiovascular: with the use of the drug in high doses, a decrease in blood pressure, tachycardia, angina, heart rhythm disturbances, flushing of the skin of the face, blood flushes to the skin of the face and upper chest, edema are possible.
Allergic reactions: possible - itching, skin rash, urticaria, angioedema; rarely - anaphylactic shock.
From the hematopoietic system and hemostasis: rarely - bleeding (from the vessels of the stomach, intestines, skin and mucous membranes), thrombocytopenia, leukopenia, pancytopenia, hypofibrinogenemia, changes in the pattern of peripheral blood, aplastic anemia. In this regard, it is necessary to conduct regular monitoring of the blood picture.
Other: rarely - malaise, increased fragility of the nails, changes in body weight, nasal congestion.

Treatment should be under the control of blood pressure. In diabetic patients taking hypoglycemic drugs, the appointment in large doses can cause severe hypoglycemia (dose adjustment is required). When administered simultaneously with anticoagulants, it is necessary to carefully monitor blood coagulation parameters. In patients who have recently undergone surgery, systematic monitoring of Hb and hematocrit is necessary. The dose should be reduced in patients with low and unstable blood pressure. Older people may need to reduce the dose (increased bioavailability and reduced rate of excretion). The safety and efficacy of pentoxifylline in children is not well understood. Tobacco smoke can reduce the therapeutic efficacy of the drug. The compatibility of the pentoxifylline solution with the infusion solution should be checked in each particular case.

Drug interactions

Pentoxifylline may enhance the effect of drugs affecting the blood coagulation system (indirect and direct anticoagulants, thrombolytics), antibiotics (including cephalosporins - cefamandol, cefeperazone, cefotetan), valproic acid. Increases the effectiveness of antihypertensive drugs, insulin and oral hypoglycemic drugs. Cimetidine increases the concentration of pentoxifylline in plasma (the risk of side effects). Joint appointment with other xanthines can lead to excessive nervous excitement of patients.

Overdosage

Symptoms: nausea, dizziness, decrease in blood pressure, fever (chills), tachycardia, drowsiness or agitation, loss of consciousness, areflexia, tonic-clonic convulsions, vomiting like "coffee grounds" (as a sign of gastrointestinal bleeding), arrhythmias are possible.
