Pharmacological properties.

Pharmacodynamics.

Isoxsuprine is a peripheral vasodilator and a beta-adrenoceptor agonist. By stimulating beta-adrenoceptors, isoxsuprine reduces the tone of smooth muscles in blood vessels, relieves their spasm, and improves peripheral and cerebral circulation, thereby enhancing tissue blood supply. It exerts a positive inotropic and chronotropic cardiac effect, as well as a tocolytic effect. In in vitro and in vivo studies, isoxsuprine suppressed both spontaneous and oxytocin-induced uterine activity during labor.

Isoxsuprine also produces a mild broncholytic effect. At high doses, it inhibits platelet aggregation and reduces blood viscosity.

Pharmacokinetics.

Isoxsuprine is rapidly absorbed from the gastrointestinal tract. It undergoes partial hepatic conjugation metabolism. After oral administration, maximum plasma concentration is reached within approximately 1 hour. The elimination half-life is approximately 1.25 hours. The drug is excreted predominantly in the urine, and to a minor extent in the feces.

Clinical characteristics.

Indications.

Disorders of peripheral circulation, including obliterating endarteritis, obliterating atherosclerosis of limb arteries, diabetic angiopathy, Raynaud's disease and Raynaud's syndrome.

Chronic cerebral vascular insufficiency due to cerebral atherosclerosis.

Atherosclerosis of retinal arteries.

Contraindications.

Interaction with other medicinal products and other forms of interaction.

There are no data regarding negative interactions of isoxsuprine with other medicinal products. The vasodilating effect may be enhanced when used concomitantly with vasodilators used in cardiology.
