Pentalgin, 12 pcs.

Pharmacotherapeutic group: analgesic (analgesic non-narcotic + non-steroidal anti-inflammatory drug + psychostimulant + antispasmodic + H₁-histamine receptor blocker).

ATC code: N02BE71

Pharmacological properties

Combined drug, has analgesic, anti-inflammatory, antispasmodic, antipyretic effect.

Paracetamol is a non-narcotic analgesic which has antipyretic and analgesic effect caused by blockade of cyclooxygenase in the central nervous system and by influence on the centers of pain and thermoregulation.

Naproxen is non-steroidal anti-inflammatory drug which has anti-inflammatory, analgesic and antipyretic effect due to non-selective inhibition of cyclooxygenase activity which regulates synthesis of prostaglandins.

Caffeine causes dilatation of blood vessels in skeletal muscles, heart, kidneys; it increases mental and physical performance, eliminates fatigue and sleepiness; it increases permeability of histohematic barriers and increases bioavailability of non-narcotic analgesics, thus enhancing therapeutic effect. It has a tonic effect on cerebral vessels.

Drotaverine has myotropic antispasmodic effect caused by inhibition of phosphodiesterase IV and acts on smooth muscles in the gastrointestinal tract, biliary tract, genitourinary and vascular systems.

Pheniramine is a blocker of H1-histamine receptors. It has antispasmodic and mild sedative effects, reduces the phenomena of exudation, and enhances the analgesic effect of paracetamol and naproxen.

Interaction

In concomitant administration of the drug Pentalgin with barbiturates, tricyclic antidepressants, rifampicin, ethanol the risk of hepatotoxic effects increases (these combinations should be avoided).

Paracetamol increases the effect of indirect anticoagulants and reduces the effectiveness of uricosuric drugs.

Long-term use of barbiturates reduces the effectiveness of paracetamol.

The simultaneous use of paracetamol with ethanol increases the risk of acute pancreatitis.

Microsomal oxidation inhibitors (including cimetidine) reduce the risk of hepatotoxic effects of paracetamol.

Diflunisal increases the plasma concentration of paracetamol by 50%, which increases the risk of hepatotoxicity.

Naproxen may cause decreased diuretic effect of furosemide, increased effect of indirect anticoagulants, increased toxicity of sulfonamides and methotrexate, decreased excretion of lithium and increased its concentration in plasma.

The co-administration of caffeine and barbiturates, primidone, anticonvulsants (hydantoin derivatives, especially phenytoin) may increase the metabolism and clearance of caffeine; concomitant use of caffeine and cimetidine, oral contraceptives, disulfiram, ciprofloxacin, norfloxacin decreases caffeine metabolism in the liver (slowing its excretion and increasing blood concentrations).

The simultaneous use of caffeine-containing drinks and other CNS-stimulating agents may lead to excessive CNS stimulation.

Concomitant use of drotaverine may impair the antiparkinsonian effect of levodopa.

Concomitant use of pheniramine with tranquilizers, hypnotics, MAO inhibitors, ethanol may increase CNS depressant effects.

Special Instructions

The concomitant use of the drug with other drugs containing paracetamol and/or other non-steroidal anti-inflammatory drugs, as well as with the means for relief of symptoms of “colds”, flu and nasal congestion should be avoided.

When using the drug for more than 5-7 days, peripheral blood parameters and the functional state of the liver should be monitored.

Paracetamol distorts the results of laboratory studies of plasma glucose and uric acid.

If it is necessary to determine 17-ketosteroids, the drug should be canceled 48 hours before the study. Note that naproxen increases bleeding time.

The effect of caffeine on the central nervous system depends on the type of nervous system and may manifest as excitation or inhibition of higher nervous activity.

Periods of alcoholic beverages should not be consumed during treatment.

Impact on the ability to drive vehicles and mechanisms

During treatment, caution should be exercised when driving motor transport and engaging in other potentially dangerous activities requiring increased concentration and rapid psychomotor reaction.
