Pharmacodynamics

Drotaverinum is a derivative of isoquinoline which exhibits a powerful antispasmodic effect on smooth muscle due to enzyme inhibition of phosphodiestephosphate. The enzyme phosphodiesterase is necessary for the hydrolysis of cyclic adenosine monophosphate (cAMP) to adenosine monophosphate (AMP). Inhibition of the phosphodiesterase enzyme leads to an increase in cAMP concentration which triggers the following cascade reaction: high cAMP concentrations activate cAMP-dependent phosphorylation of myosin light chain kinase phosphorylation (MLC). Phosphorylation of MLCK leads to a decrease in its affinity for the Ca2 + -calmodulin complex, as a result of which the inactivated form of MLCK supports muscle relaxation. cAMP also affects the cytosolic concentration of Ca2 + ion due to the stimulation of Ca2 + transport to extracellular space and sarcoplasmic reticulum. This effect of drotaverine through cAMP lowering the concentration of Ca2 + ion explains the antagonistic effect of drotaverinate with respect to Ca2 +.

In vitro, drotaverine inhibits PDE IV isoenzyme without inhibiting PDE III and PDEV isoenzymes. Therefore, the effectiveness of drotaverine depends on the concentration of PDE IV in tissues, the content of which varies in different tissues. PDE IV is most important for suppressing contractile activity of smooth muscles, therefore, selective inhibition of PDE IV may be useful for the treatment of hyperkinetic dyskinesias and various diseases accompanied by a spastic condition of the gastrointestinal tract.

The hydrolysis of cAMP in the myocardium and vascular smooth muscle occurs mainly with the help of the PDE III isoenzyme, which explains the fact that with high antispasmodic activity, drotaverine has no serious side effects from the heart and blood vessels and pronounced effects on the cardiovascular system .

Drotaverinum is effective for spasms of smooth muscles of both neurogenic and muscular origin. Regardless of the type of autonomic innervation, drotaverin relaxes the smooth muscles of the gastrointestinal tract, biliary tract, and genitourinary system.

Pharmacokinetics

Absorption:

After oral administration, drotaverine is rapidly and completely absorbed. After a presystemic metabolism, 65% of the accepted dose of drotaverine enters the systemic circulation. The maximum plasma concentration (Cmax) is reached after 45-60 minutes.

Distribution of

In vitro drotaverin has a high plasma deal (95-98%), especially with albumin and - globumins.

Drotaverine is evenly distributed throughout the tissues, penetrates smooth muscle cells. Does not cross the blood-brain barrier. Drotaverin and / or its metabolites may slightly penetrate the placental barrier.

Metabolism

In humans, drotaverine is almost completely metabolized in the liver by O-deethylation. Its metabolites are rapidly conjugated to glucuronic acid. The main metabolite is 4'-desethyldrotaverine, in addition to which 6-desethyldrotaverin and 4'-desethyldrothaveraldine were identified.

Derivation of

In humans, a two-chamber mathematical model was used to evaluate the pharmacokinetics of drotaverine. The final half-life of plasma radioactivity was 16 hours.

Within 72 hours, drotaverine is almost completely eliminated from the body. More than 50% of drotaverin is excreted by the kidneys and about 30% through the gastrointestinal tract (excretion into bile). Drotaverin is mainly excreted in the form of metabolites, unchanged drotaverin in urine is not detected. Buy No-shpa tablets 40 mg 64 pcs. (Drotaverine) in florida free shipping.

Composition of

Active ingredient: drotaverine hydrochloride - 40 mg

excipients: magnesium stearate - 3 mg, talcum powder - 4 mg, povidone - 6 mg mg srdl, srd lactose monohydrate - 52 mg.

Dosage and administration of

Adults

Typically, the average daily dose in adults is 120-240 mg (daily dose is divided into 2-3 doses). The maximum single dose is 80 mg. The maximum daily dose is 240 mg.

Children

clinical studies using drotaverine in children have not been conducted.

In case of prescribing drotaverine to children:

- for children from 6 to 12 years old, the maximum daily dose is 80 mg, divided into 2 doses.

- for children over 12 years of age, the maximum daily dose is 160 mg, divided into 2-4 doses. Duration of treatment without consulting a doctor

When taking the drug without consulting a doctor, the recommended duration of taking the drug is usually 1-2 days. If during this period the pain does not decrease, the patient should consult a doctor to clarify the diagnosis and, if necessary, change the therapy. In cases where drotaverine is used as adjuvant therapy, the duration of treatment without consulting a doctor may be longer (2-3 days).

Method for assessing the effectiveness of

If a patient can easily diagnose the symptoms of his disease on his own, since they are well known to him, the effectiveness of the treatment, namely the disappearance of pain, is also easily evaluated by the patient. If within a few hours after taking the maximum single dose there is a moderate decrease in pain or, the absence of a decrease in pain, or if the pain does not significantly decrease after taking the maximum daily dose, it is recommended to consult a doctor.

Side effects

The following are the adverse reactions observed in clinical trials, divided into systems, organs with an indication of their frequency of occurrence in accordance with the following gradations: very frequent (? 10%), frequent (? 1%, <10) infrequent (? 0.1%, <1%) rare (? 0.01%, <0.1%) and very rare, including single messages (<0.01%), unknown frequency (according to available data frequency cannot be determined).

From the cardiovascular system

Rare - increased heart rate, lowering blood pressure.

From the nervous system

Rare - headache, dizziness, insomnia.

From the gastrointestinal tract

Rare - nausea, constipation.

On the part of the immune system

Rare - allergic reactions (angioedema, urticaria, rash, itching) (see section "Contraindications").

Drug Interactions

With levodopa

Phosphodiesterase inhibitors like papaverine reduce the antiparkinsonian effect of levodopa. With the appointment of drotaverine simultaneously with levodopa, increased rigidity and tremor are possible. With other antispasmodic drugs, including m-anticholinergic drugs. Mutual enhancement of antispasmodic action.

Drugs that significantly bind to plasma proteins (more than 80%)

Drotaverin significantly binds to plasma proteins, predominantly albumin,

? and? -globulins (see the section "Pharmacokinetics"). There is no data on the interaction of drotaverine. with drugs that significantly bind to plasma proteins, however, there is a hypothetical possibility of their interaction with drotaverine at the level of protein binding (displacing one of the drugs with another due to protein and increasing the concentration of the free fraction in the blood of a drug with a less strong protein binding), which is hypothetically may increase the risk of pharmacodynamic and / or toxic side effects of this drug.

Overdose

There are no data on overdose of the drug.

In case of overdose, patients should be under medical supervision and, if necessary, they should undergo symptomatic and aimed at maintaining the basic functions of the body treatment, including artificial inducing vomiting or gastric lavage.
