Pharmacological action
Dusopharm has a vasodilating effect, as a result of which it improves peripheral and cerebral blood circulation. It causes a decrease in peripheral vascular resistance and increases the minute volume of the heart, without significantly affecting heart rate and blood pressure.
The vasodilating effect of Dusopharm is the result of its direct myotropic, antagonistic to serotonin 5HT2 receptors and alpha-adrenoblocking action.
It has an M-holinoblocking effect.
It has a positive effect on cellular metabolism, improving the utilization of oxygen and glucose. This effect of the drug is due to its ability to increase ATP levels and inhibit the enzyme succinate dehydrogenase.
Activates glucose utilization through the citric acid cycle and increases the conversion of succinic acid to fumaric acid. As a result, the resistance of cells (including the brain) to hypoxia increases. In addition, Dusopharm reduces the increased viscosity of the blood.
Indications
The recovery period of cerebral circulatory disorders; peripheral circulatory disorders (intermittent lameness, Raynaud's disease, trophic ulcers).
Contraindications
Increased individual sensitivity to the drug. Myocardial infarction (acute stage).
Arterial hypotension. Hemorrhagic stroke (acute stage).
Epilepsy, increased convulsive readiness.
Stage II–III chronic heart failure (NYHA III–IV functional classification of heart failure by the New York Association of Cardiologists).
Tachyarrhythmias. Age under 18 years (efficacy and safety have not been established).
