Pharmacodynamics . Substances that are part of the drug, have a beneficial effect on the vessels. Dihydroergocristine is a semi-synthetic derivative of the alkaloid group. Blocks α-adrenoreceptors, thereby reducing the tone of smooth muscles and total peripheral vascular resistance. It helps to strengthen and improve the elasticity of the venous walls. Esculin and rutoside - substances of natural origin. Reduce the permeability and fragility of the vascular walls, have anti-inflammatory and anti-edema effect.
Pharmacokinetics. About 25% of dihydroergocristine is absorbed into the digestive tract. 68% of the active substance is bound to plasma proteins. The withdrawal period is 14 hours. Dihydroergocristine is excreted with bile. Penetrates through the placental barrier and is absorbed into breast milk.
Rutoside is absorbed into the blood. Its maximum concentration in the blood is reached in 1–9 hours. The elimination half-life of ruthoside is 10–25 hours. It is displayed mainly in the form of metabolites, a small part - in unchanged form.
Data on the pharmacokinetics of esculin are not available.
