Drotaverin forte - instructions for use, dose, side effects, contraindications

Myotropic antispasmodic. The chemical structure and pharmacological properties of the drug is close to papaverine, but it has a stronger and longer action. Reduces the intake of calcium ions in smooth muscle cells (inhibits phosphodiesterase, leads to the accumulation of intracellular cyclic adenosine monophosphate).Reduces the tone of the smooth muscles of internal organs and intestinal motility, dilates the blood vessels. Does not affect the autonomic nervous system. The presence of direct influence on smooth muscles can be used as an antispasmodic in cases when drugs from the group of m-holinoblockers are contraindicated (closed-angle glaucoma, prostatic hyperplasia).

Pharmacokinetics:

When taken orally, absorption is high, the half-absorption period is 12 min. Bioavailability is 100%. Evenly distributed in tissues, penetrates smooth muscle cells. Time to reach the maximum concentration of the drug in the blood plasma (TSmAh) - 2 hours. The connection with plasma proteins is 95-98%. It is mainly excreted by the kidneys, to a lesser extent - with bile. Does not penetrate the blood-brain barrier.

Indications:

Spasm of smooth muscles of internal organs (dyskinesia of bile ducts and gall bladder by hyperkinetic type, cholecystitis, postcholecystectomy syndrome); pyelitis; spastic constipation, spastic colitis, proctitis, tenesmus; pilorospazm, gastroduodenitis, peptic ulcer of the stomach and duodenum (in the phase of exacerbation,in the complex therapy - for a pain relief syndrome of a spastic character). Spasm of peripheral, cerebral arteries. Algodismenorea.

Symptoms: in large doses violates the atrioventricular conductivity, reduces the excitability of the heart muscle, can cause cardiac arrest and paralysis of the respiratory center.

Symptomatic treatment: Activated carbon, intravenously sodium bicarbonate solution for lactic acidosis, intravenous fluids for maintenance of intravascular volume, calcium can be used at the occurrence of undesirable cardiovascular effects, dopamine as a vasopressor.

Strengthens the effect of papaverine, bendazole and other antispasmodics (including m-holinoblokatorov), increases the reduction in arterial pressure caused by tricyclic antidepressants, quinidine and procainamide. Reduces the spasmogenic activity of morphine. Phenobarbital increases the severity of spasmolytic action of drotaverine.
