INSTRUCTION FOR THE SPECIALIST.
Description of the drug approved by the manufacturer for the printed edition of 2014.
PHARMACHOLOGIC EFFECT
Yunispaz-N is a combined preparation that has analgesic and spasmolytic effects.
Paracetamol, an analgetic-antipyretic, has a weakly expressed anti-inflammatory effect, the mechanism of which is associated with inhibition of the synthesis of prostaglandins in the central nervous system, and to a lesser extent by peripheral action, the blocking of prostaglandins and other active substances that stimulate pain receptors.
Drotaverine is an isoquinoline derivative with spasmolytic effect on smooth muscle (inhibition of the enzyme phosphodiesterase IV, an increase in the concentration of cAMP, which inactivating the enzyme - myosinkinase, results in relaxation of the smooth muscles of blood vessels, gastrointestinal tract, bile ducts and organs of the genitourinary system.
PHARMACOKINETICS
Paracetamol is rapidly absorbed into the upper gastrointestinal tract and distributed to most organs and tissues. T 1/2 is between 1.25 and 3 hours. It is metabolized predominantly by conjugation and subsequent excretion of metabolites through the kidneys. About 85% of the ingested dose is withdrawn within 24 hours, mainly in the form of glucuronide compounds with a small number of other compounds and drug residues.
Drotaverina hydrochloride is rapidly absorbed after oral administration. It undergoes biotransformation in the liver to monophenolic compounds, which, in turn, are conjugated to glucuronic acid. T 1/2 is 16-22 hours, while about half the dose is excreted in the urine, and from 10 to 30% with feces.
INDICATIONS
Pain syndrome caused by spasms of smooth muscles:
- Gastrointestinal tract (spastic constipation, irritable bowel syndrome);
- biliary tract (cholelithiasis, cholecystitis, cholangitis);
- urinary tract (urolithiasis, pyelitis, cystitis);
- vessels of the brain (headaches);
- with diseases of female genital organs (dysmenorrhea, adnexitis);
- myalgia, arthralgia, neuralgia, ischialgia;
- toothache.
DOSING MODE
Inside. The drug is recommended for use on 1-2 tablets. at one time, if necessary, you can repeat the reception after 8 hours.

Older patients with normal liver and kidney function are not required to adjust the dose.
In severe violations of the liver and kidneys, the dose of the drug should be reduced. At a glomerular filtration rate of less than 10 ml / min, the time passing between taking 2 doses should be more than 12 hours. Only occasional use of the drug is allowed in this category of patients.
The maximum duration of treatment without consulting a doctor is 3 days.

APPLICATION FOR FUNCTIONS OF THE LIVER
Contraindicated in severe renal failure.
In severe violations of the liver and kidneys, the dose of the drug should be reduced.
APPLICATION FOR VIOLATIONS OF THE FUNCTION OF KIDNEYS
Contraindicated in severe hepatic insufficiency.
In severe violations of the liver and kidneys, the dose of the drug should be reduced.
APPLICATION FOR CHILDREN
Contraindicated in children under 6 years.
Children aged 6 to 12 years, the drug is prescribed in a single dose of 1 / 2-1 tab. Repeated use of the drug is possible in 10-12 hours, the maximum dose is 2 tablets / day.
APPLICATION IN ELDERLY PATIENTS
With caution appoint the drug to elderly patients.
Older patients with normal liver and kidney function are not required to adjust the dose.
SPECIAL INSTRUCTIONS
If it is necessary to use the drug for more than 3 days, consult a doctor.
With caution appoint the drug to patients with constitutional hyperbilirubinemia (Gilbert's syndrome), patients of advanced age and with arterial hypotension.
When taking the drug is prohibited the consumption of alcoholic beverages.
In renal and hepatic insufficiency, the dose should be set individually.
When using the drug for more than 3 days and / or at high doses, it is necessary to monitor the picture of peripheral blood and the functional state of the liver (the number of leukocytes, platelets, and the level of creatinine and the activity of liver enzymes in the blood).
Clinical and laboratory symptoms of hepatotoxic effect begin to appear within 48-72 hours after taking large doses of the drug.
Impact on the ability to drive vehicles and manage mechanisms
The question of the possibility of engaging in activities requiring an increased concentration of attention and speed of psychomotor reactions should be resolved after assessing the patient's individual response to the drug.
OVERDOSE
Symptoms: pallor of the skin, nausea, vomiting, toxic damage to the liver, until the development of necrosis, increased activity of hepatic transaminases, an increase in prothrombin time. When overdosing, it is urgent to see a doctor.
Treatment: gastric lavage followed by administration of activated charcoal; symptomatic therapy, the introduction of methionine and N-acetylcysteine.
DRUG INTERACTION
Drotaverin reduces the action of levodopa (tremor and stiffness may increase).
When paracetamol is used together with drugs that induce the induction of liver enzymes (salicylamide, barbiturates, antiepileptic, tricyclic antidepressants, alcohol, rifampicin), the concentration of toxic metabolites of paracetamol increases.
When applying paracetamol simultaneously with chloramphenicol, the half-life of the latter increases and its toxicity increases.
Simultaneous use of paracetamol with doxirubicin increases the risk of liver function disorders.
Paracetamol reduces the effect of uricosuric drugs.
Metoclopramide and domperidone increase the absorption of paracetamol, and colestyramine decreases it.
With prolonged use of the drug, the risk of bleeding increases due to the presence of paracetamol.
