Latin name
Vasonit
packaging 20 pcs
Pharmacological action
Wazonite – angioprotective, antiplatelet, vasodilator.
Improves microcirculation and rheological properties of blood. It inhibits phosphodiesterase, contributing to the accumulation of cAMP in tissues and organs, including in the cells of the smooth muscles of blood vessels, in the formed elements of the blood.
It inhibits platelet and erythrocyte aggregation, increases the elasticity of their membranes, lowers plasma fibrinogen concentration and enhances fibrinolysis. Improves the supply of tissue with oxygen, most in the limbs, central nervous system and, to a lesser extent, in the kidneys. Slightly dilates the coronary vessels.
Pharmacokinetics
When ingestible tablets are administered, the active substance is continuously released and absorbed uniformly from the digestive tract. It undergoes metabolism in the liver during the “first passage”, as a result of which a number of pharmacologically active metabolites are formed.
Cmax of pentoxifylline and its active metabolites in plasma is reached after 3-4 hours and remains at the therapeutic level for 12 hours. It is excreted mainly with urine in the form of metabolites.
Indications
Peripheral circulatory disorders (intermittent claudication against the background of diabetic angiopathy, obliterating endarteritis), Raynaud ² ¢s disease, tissue trophic disorders (postthrombotic syndrome, varicose veins, trophic ulcers of the leg, gangrene, otorrhagia, and otorrhagia)
cerebral atherosclerosis (dizziness, memory impairment, sleep disturbance), discirculatory encephalopathy, viral neuroinfection (prevention of possible microcirculatory disturbance)
ischemic heart disease, condition after myocardial infarction
acute circulatory disorders in the retina and choroid of the eye otosclerosis, degenerative changes in the background of vascular pathology of the inner ear with a gradual hearing loss
Asthma pulmonary artery disease, bronchial vascular disease.

Drug Interaction
Pentoxifylline may enhance the action of drugs that affect the blood coagulation system (indirect and direct anticoagulants, thrombolytics), anitibiotics (including cephalosporins – cefamandol, cefapetazole, cefapetazole, cefatrazole).
Increases the effectiveness of hypotensive drugs, insulin and oral hypoglycemic drugs.
Cimetidine increases the concentration of pentoxifylline in plasma (risk of side effects).
Joint appointment with dr. xanthines can lead to excessive nervous excitation of patients.
Overdose
Symptoms: nausea, dizziness, decrease in blood pressure, fever, tachycardia, drowsiness or agitation, loss of consciousness, areflexia, tonic-clonic convulsions, vomiting, like arrhythmias.
