Spasmonet, tablets 40 mg 20 pcs

Spasmonet is an antispasmodic agent.

Pharmacodynamics

Drotaverine is a myotropic antispasmodic, similar in chemical structure and pharmacological properties to papaverine, but with a stronger and longer action.

Decreases influx of calcium ions into smooth muscle cells.

Limits smooth muscle tone of internal organs and intestinal peristalsis, dilates blood vessels. It does not affect the autonomic nervous system, does not penetrate into the CNS. Its direct effect on the smooth muscles allows it to be used as an antispasmodic when drugs from the group of M-cholinoblockers are contraindicated (closed-angle glaucoma, prostatic hypertrophy).

Pharmacokinetics

In oral administration absorption is high. Bioavailability is 100%.

Distributes evenly throughout tissues, penetrates smooth muscle cells.

Maximal concentration in blood reaches after 2 hours. Binding with plasma proteins is 80-90%.

The elimination half-life is 7-12 hours. Drotaverine is actively metabolized in the liver, excreted mainly by the kidneys, to a lesser extent with the bile. Does not penetrate the blood-brain barrier.

Interaction

Drotaverine may weaken the antiparkinsonian effect of levodopa when used concomitantly.

It enhances the effect of papaverine, bendazole and other antispasmodics (including m-cholinoblockers), reduces blood pressure caused by tricyclic antidepressants, quinidine and procainamide. Phenobarbital increases the spasmolytic effect of drotaverine.

Drotaverine reduces the antispasmodic activity of morphine.

Use Spasmonet with caution in severe coronary atherosclerosis.

Impact on the ability to drive and operate machinery.
