Pharmacological action of
A vasodilating, improves microcirculation, normalizes the rheological properties of blood. Pentoxifylline reduces blood viscosity, causes platelet disaggregation, increases the elasticity of red blood cells (due to the effect on pathologically altered red blood cell deformability, increases red blood cell count). It 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 heart rate, an increase in stroke volume and minute blood volume without a significant change in heart rate. Expanding coronary arteries, increases oxygen delivery to the myocardium, dilating the vessels of the lungs, improves blood oxygenation. Increases the tone of the respiratory muscles (intercostal muscles and diaphragm). Increases the concentration of ATP in the brain, favorably affects the bioelectric activity of the central nervous system. It improves microcirculation in areas of impaired blood supply. In case of occlusive lesion of the peripheral arteries (intermittent claudication), it leads to an increase in walking distance, elimination of night cramps of calf muscles and pain at rest.
Peripheral circulatory disorders of atherosclerotic origin (e.g. intermittent claudication). Diabetic angiopathy. Trophic disorders (e.g. leg ulcers, gangrene). Cerebral circulatory disorders (consequences of cerebral atherosclerosis, such as impaired attention concentration, dizziness, memory impairment). Ischemic and post-stroke states. Circulatory disorders in the retina choroid of the eye. Otosclerosis. Degenerative changes against the background of pathology of the vessels of the inner ear and hearing loss.
Acute myocardial infarction, massive bleeding, cerebral hemorrhage, massive retinal hemorrhage, pregnancy, lactation (breastfeeding), children and adolescents under 18 years of age, hypersensitivity to pentoxifylline, other derivatives of methylx.
