No-shpa - tablets 100 pcs., drotaverin 40 mg, with abdominal pain

Round biconvex tablets of yellow with a greenish or orange tinge, with spa engraving on one side.

Pharmacodynamics

Drotaverine is an isoquinoline derivative that exhibits a potent antispasmodic effect on smooth muscle by inhibiting the type IV phosphodiesterase enzyme (PDE IV).

Inhibition of the enzyme PDE IV leads to an increase in the concentration of cAMP, inactivation of myosin light chain kinase, which further causes relaxation of smooth muscles.

The effect of drotaverine through cAMP, which reduces the concentration of Ca 2+ ions, explains the antagonistic effect of drotaverine in relation to Ca 2+ ions.

In vitro, drotaverine inhibits the PDE IV enzyme without inhibiting the PDE III and PDE V enzymes.

Therefore, the effectiveness of drotaverine depends on the concentrations of PDE IV in different tissues.

PDE IV is most important for suppressing the contractile activity of smooth muscles, and therefore selective inhibition of PDE IV may be useful for the treatment of hyperkinetic dyskinesias and various diseases accompanied by a spastic state of the gastrointestinal tract.

Hydrolysis of cAMP in the myocardium and vascular smooth muscle occurs mainly with the help of the enzyme PDE III, which explains the fact that with high spasmolytic activity, drotaverine does not have serious side effects from the heart and blood vessels and pronounced effects on the cardiovascular system.

Drotaverine is effective for smooth muscle spasms of both neurogenic and muscular origin.

Regardless of the type of autonomic innervation, drotaverine relaxes the smooth muscles of the gastrointestinal tract, biliary tract, and the genitourinary system.

Due to its vasodilating effect, drotaverine improves tissue blood supply.

Thus, the above-described mechanisms of action of drotaverine eliminate smooth muscle spasm, which leads to a decrease in pain.

Pharmacokinetics

Absorption

Compared with papaverine, when taken orally, drotaverine is absorbed faster and more completely from the gastrointestinal tract.

After presystemic metabolism, 65% of the taken dose of drotaverine enters the systemic circulation.

The maximum concentration (C max) of drotaverine in the blood plasma is reached after 45-60 minutes.

Distribution

In vitro, drotaverine has a high binding to plasma proteins (95-98%), especially albumin,?

and? - globulins.

Drotaverine is evenly distributed in tissues, penetrates into smooth muscle cells.

Does not penetrate the blood-brain barrier.

Drotaverine and / or its metabolites can slightly penetrate the placental barrier.

Metabolism

Drotaverine is almost completely metabolized in the liver.

Withdrawal

The half-life of drotaverine is 8-10 hours.

Within 72 hours, drotaverine is almost completely excreted from the body.

About 50% of drotaverine is excreted by the kidneys and about 30% through the gastrointestinal tract.

Drotaverine is mainly excreted in the form of metabolites, the unchanged form of drotaverine is not found in urine.
