Pentalgin Neo, 50 mg+220 mg+325 mg 20 pcs.
Pharmacotherapeutic group: combined analgesic (non-steroidal anti-inflammatory agent + analgesic non-narcotic agent + psychostimulant).
ATX code: N02BE71
Naproxen: non-steroidal anti-inflammatory agent, has analgesic, antipyretic and anti-inflammatory effects. The mechanism of action is due to non-selective inhibition of cyclooxygenase-1 and -2 (COX-1, COX-2) activity, which regulates the synthesis of prostaglandins. The use of naproxen in the form of sodium naproxen salt provides faster absorption and rapid onset of analgesic effect.
Paracetamol: non-narcotic analgesic, has antipyretic and analgesic effect caused by blockade of cyclooxygenase in the central nervous system and effects on the centers of pain and thermoregulation.
Caffeine: decreases sleepiness and fatigue, increases mental and physical performance; it dilates blood vessels of skeletal muscles, heart and kidneys and decreases platelet aggregation. In this combination, caffeine at a low dose has almost no simulative effect on the central nervous system, increases the tone of cerebral vessels and helps accelerate blood flow. Caffeine increases permeability of histohematic barriers and increases bioavailability of non-narcotic analgesics and decreases COX activity, as it is an antagonist of adenosine A(2A) and A(2B) receptors, which helps to increase analgesic effect.
In a registrational clinical study of the drug Pentalgin® NEO the superiority in terms of the effect on overall pain relief (TOTPAR score) compared to naproxen monodrug and to the combined drug of paracetamol and caffeine has been confirmed.
Naproxen: is rapidly and completely absorbed from the gastrointestinal tract (GIT). Bioavailability is 95% (eating has almost no effect on the completeness or speed of absorption). Time to reach maximum blood concentration (Tmax) is 1-2 hours. Blood plasma protein binding > 99 %. The elimination half-life (T1/2) is 12-15 hours. Metabolism occurs in the liver to dimethylnaproxen with participation of CYP2C9 isoenzyme. Clearance is 0.13 ml/min/kg. Excreted by the kidneys is 98%, 10% is excreted unchanged, 0.5-2.5% is excreted in the bile. Equilibrium concentration in blood plasma is determined after 4-5 doses of the drug (2-3 days).
Paracetamol: easily absorbed in the gastrointestinal tract, the StaX is reached after 0.5-2 hours and is 5-20 mcg/ml, plasma protein binding – 15%. It penetrates the blood-brain barrier. Paracetamol is metabolized in the liver and excreted by the kidneys, mainly as glucuronides and sulfate conjugates. Less than 5% of paracetamol is excreted unchanged. T1/2 varies from 1 to 4 h.
Caffeine: completely and rapidly absorbed in the gastrointestinal tract, the Stax is reached in 50-75 minutes and is 1.58-1.76 mg/L. It is rapidly distributed in all organs and tissues of the body and easily passes through the blood-brain barrier and the placenta. Binding with blood proteins is 25-36%. More than 90% is metabolized in the liver. T1/2 in adults is 3.9-5.3 hours (sometimes up to 10 hours) Excretion of caffeine and its metabolites is done by kidneys (1-2% of adults excrete unchanged).
Pain syndrome of different genesis:
- in diseases of the musculoskeletal system (osteoarthritis of the peripheral joints and spine, including with radicular syndrome, arthritis, myalgia);
- dental pain;
- headache, migraine;
- posttraumatic (sprains and bruises) and postoperative pain syndrome accompanied by inflammation.
Pentalgin® NEO is used for symptomatic therapy (decrease in pain and inflammation) and has no effect on the progression of the underlying disease.

How to take, the dosage
Inside. The tablets should be taken with plenty of water.
The daily dose is 1 tablet.
Frequency of administration – 1-3 times a day, with an interval of at least 4 hours.
Maximal daily dose is 3 tablets.
Duration of preparation use – not more than 5 days.
Other NSAIDs, including selective cyclooxygenase-2 inhibitors, corticosteroids: increased risk of gastrointestinal side effects of naproxen.
Propranololol and other beta-adrenoblockers: naproxen may decrease the antihypertensive effect of the drugs. Caffeine may inhibit the therapeutic effects of beta-adrenoblockers.
Heart glycosides: caffeine accelerates absorption and enhances the effect of cardiac glycosides, increases their toxicity.
Diuretics: naproxen may decrease the diuretic effect of diuretics, inhibit the natriuretic effect of furosemide. Diuretics may increase the risk of nephrotoxicity of NSAIDs.
Lithium: naproxen decreases lithium excretion, which leads to increased plasma lithium concentrations.
Myelotoxic drugs: increase hematoxicity of naproxen.
Cyclosporine: increased risk of renal failure.
Probenecid: increases the plasma concentration of naproxen.
Methotrexate, phenethiones, sulfonamides: naproxen slows down their excretion, which increases the risk of their toxic effects.
Antacids containing magnesium and aluminum: decreased absorption of naproxen.
Anticoagulants: naproxen may increase the effect of anticoagulants, paracetamol with long-term use increases the effect of indirect anticoagulants.
Antiplatelet drugs, selective serotonin reuptake inhibitors: increased risk of gastrointestinal bleeding.
Mifepristone: concomitant administration of NSAIDs for 8-12 days after mifepristone administration is not recommended.
Tacrolimus: concomitant use of NSAIDs increases the risk of nephrotoxicity.
Diflunisal: increased plasma concentrations of paracetamol, which increases the risk of hepatotoxicity.
Hepatic microsomal enzyme inducers: increased hepatotoxic effects of paracetamol may occur.
Hepatic microsomal enzyme inhibitors: decrease the risk of hepatotoxic effects of paracetamol.
Chloramphenicol: paracetamol increases the elimination time of chloramphenicol.
Methoclopramide, domperidone: increase the rate of absorption of paracetamol.
Colestyramine: decrease the rate of absorption of paracetamol.
Theophylline: caffeine decreases the excretion of theophylline.
Barbiturates, primidone, anticonvulsants: may increase metabolism and increase caffeine clearance.
Cimetidine, oral contraceptives, disulfiram, ciprofloxacin, norfloxacin: possible decrease in metabolism of caffeine in the liver (delayed excretion and increased blood concentrations).
Calcium preparations: caffeine decreases their absorption in the gastrointestinal tract.
Drugs and sleeping pills: caffeine decreases their effectiveness.
Alcohol: increased risk of liver damage and acute pancreatitis.
Do not exceed the doses given in the instructions. To reduce the risk of adverse events, use the lowest effective dose for the shortest possible course.
If pain persists or worsens with therapy, see a physician.
Long-term use of the drug requires monitoring of peripheral blood and liver function.
The drug should not be taken together with other anti-inflammatory and pain medications except when prescribed by a physician.
The drug should be avoided for 48 hours before surgery. If 17-corticosteroid determination is necessary, the drug should be withdrawn 48 hours before the study. Similarly, naproxen may affect the determination of 5-hydroxyindoleacetic acid in urine.
The use of naproxen, as well as other drugs that block the synthesis of prostaglandins, may affect fertility, so it is not recommended for women who plan to become pregnant.
At the time of treatment it is necessary to refrain from drinking alcohol-containing drinks (see section “Drug Interactions”).
When using the drug, consumption of caffeine containing products should be limited, as an excessive intake of caffeine can lead to nervousness, irritability, insomnia, and in some cases, palpitations.
Influence on laboratory values
The use of paracetamol can affect the results of uric acid determination by the phosphoric acid method and glucose oxidase/peroxidase glycemia method.
Caffeine may interfere with the dipyridamole assay; refrain from taking caffeine for 8-12 hours.
Each tablet contains approximately 20 mg of sodium. When restricting salt intake, this should be considered.
Influence on driving and operating ability
Naproxen and caffeine in the drug may affect psychomotor reaction time, therefore caution should be exercised when driving a vehicle and performing tasks requiring increased attention during treatment.
Pentalgin Neo is a new combined analgesic for modern and active people, which has a faster (due to naroxen salt compared to naproxen containing drugs) analgesic effect. Compared to naproxen monodrug and a combination of paracetamol and caffeine and a dual mechanism of pain control.
Pentalgin Neo has an anti-inflammatory effect directly at the site of pain and activates a person’s own analgesic system in the brain. Due to naproxen salt contained in it Pentalgin Neo enters the bloodstream more quickly. Due to its combined composition Pentalgin Neo has a pronounced analgesic effect.
