Pharmacological action

Pharmacotherapeutic group: nonsteroidal anti-inflammatory drug

ATX code: M 01 AE 02

Pharmacological properties

Pharmacodynamics

The drug Nalgesin® is a naproxen, has analgesic, antipyretic and anti-inflammatory effects. The mechanism of action is associated with non-selective inhibition of cyclooxygenase-1 and -2 activity (COX-1, COX-2).

The drug Nalgesin®, film-coated tablets, dissolves well, is quickly absorbed from the gastrointestinal tract and provides a rapid onset of analgesic effect.

Pharmacokinetics

It is rapidly and completely absorbed from the gastrointestinal tract. Bioavailability – 95% (food intake practically does not affect either the fullness or the rate of absorption). The time to reach the maximum concentration is 1-2 hours. Binding to plasma proteins > 99%. The elimination half-life is 12-15 hours. Metabolism occurs in the liver to dimethylnaproxene with the participation of the CYP2C9 isoenzyme. Clearance – 0.13 ml / min / kg. It is excreted 98% by the kidneys,10% is excreted unchanged, with bile – 0.5-2.5%. Steady-state plasma concentration is determined after taking 4-5 doses of the drug (2-3 days).

In case of renal failure, accumulation of metabolites is possible.

Indications

• Diseases of the musculoskeletal system (rheumatic soft tissue damage, osteoarthritis of the peripheral joints and spine, including those with radicular syndrome, tendovaginitis, bursitis).
• Mild or moderate pain syndrome: neuralgia, ossalgia, myalgia, lumboishialgia, post-traumatic pain syndrome (sprains and bruises) accompanied by inflammation, headache, migraine, algodismenorrhea, toothache.
• As part of the complex therapy of infectious and inflammatory diseases of the ear, throat, nose with severe pain syndrome (pharyngitis, tonsillitis, otitis media).
• Febrile syndrome in “colds” and infectious diseases.

The drug Nalgesin® is used for symptomatic therapy (to reduce pain, inflammation and reduce elevated body temperature) and does not affect the progression of the underlying disease.

Use during pregnancy and lactation

Nalgesin® is not recommended for use during pregnancy and lactation.

General disorders and disorders at the injection site: angioedema, hyperglycemia, hypoglycemia.

If you notice these symptoms, stop taking the drug and, if possible, consult a doctor.

Interaction

When using anticoagulants, it should be borne in mind that naproxen may increase the bleeding time.Do not use Nalgesin® concomitantly with acetylsalicylic acid, other NSAIDs, including selective cyclooxygenase-2 inhibitors (increased risk of side effects). According to clinical pharmacodynamics, concomitant use of naproxen and acetylsalicylic acid for more than one day may inhibit the effect of a low dose of acetylsalicylic acid on platelet activity, and inhibition may persist for several days after discontinuation of naproxen therapy. The clinical significance of this interaction is unknown.

Patients receiving concomitant treatment with hydantoins, anticoagulants, or other drugs that bind significantly to plasma proteins should monitor for signs of potentiation or overdose of these drugs.

Nalgesin may reduce the antihypertensive effects of propranolol and other beta-blockers, and may also increase the risk of renal failure associated with the use of angiotensin-converting enzyme (ACE) inhibitors.

NSAIDs may reduce the diuretic effect of diuretics. Naproxen inhibits the natriuretic effect of furosemide. Diuretics may increase the risk of nephrotoxicity of NSAIDs.

Inhibition of renal clearance of lithium leads to an increase in the concentration of lithium in blood plasma. Taking probenecid increases the concentration of naproxen in the blood plasma.

Cyclosporine increases the risk of developing kidney failure.

Naproxen slows down the excretion of methotrexate, phenytoin, and sulfonamides, increasing the risk of their toxic effects.

Antacids containing magnesium and aluminum reduce the absorption of naproxen.

Myelotoxic drugs increase the manifestations of hematoxicity of the drug.

According to in vitro studies, the concomitant use of naproxen and zidovudine increases the concentration of zidovudine in blood plasma.

Concomitant use of corticosteroids may increase the risk of ulceration or gastrointestinal bleeding.

NSAIDs may increase the effect of anticoagulants such as warfarin.

Simultaneous use of naproxen and antiplatelet drugs, selective serotonin reuptake inhibitors increases the risk of gastrointestinal bleeding.

Concomitant use of NSAIDs for 8-12 days after mifepristone administration is not recommended.

Concomitant use of NSAIDs and tacrolimus increases the risk of nephrotoxicity.

How to take, course of administration and dosage

Inside. Tablets should be taken with a sufficient amount of water.

Recommended treatment regimen

Adults, children 15 years and older

Usually, the daily dose used for pain relief is 2-3 tablets (550-825 mg). The maximum daily dose is 3 tablets (825 mg). Duration of application-no more than 5 days.

When using Nalgesin® as an antipyretic, the initial dose is 2 tablets, then 1 tablet (275 mg) is taken every 8 hours.

For the prevention and treatment of migraine attacks, the initial recommended dose is 2 tablets (550 mg), if necessary, you can take 1 tablet (275 mg) every 8-12 hours. The maximum daily dose is 3 tablets (825 mg).

To relieve menstrual pain and cramps, pain after the introduction of intrauterine devices (IUDs) and other gynecological pain, it is recommended to prescribe the drug in an initial dose of 2 tablets (550 mg), then 1 tablet (275 mg) every 8 hours.

Children

Nalgesin® is contraindicated for use in children under 15 years of age.

Elderly patients (3 65 years)

Patients over 65 years of age should take the drug as needed every 12 hours.

To reduce the risk of gastrointestinal adverse events, the drug should be taken at the lowest effective dose in the shortest possible course.

If you have the impression that the effect of the drug is very strong or weak, inform your doctor or pharmacist.

Overdose

Symptoms

A significant overdose of naproxen can be characterized by drowsiness, dyspeptic disorders (heartburn, nausea, vomiting, abdominal pain), weakness, tinnitus, irritability, in severe cases – bloody vomiting, melena, impaired consciousness, convulsions and kidney failure.

Treatment

Patients who have accidentally or intentionally taken a large amount of Nalgesin® should wash their stomach, take activated charcoal, and perform symptomatic therapy: antacids, _H2-receptor blockers, proton pump inhibitors. Hemodialysis is ineffective.

Description

Oval biconvex tablets covered with a film-coated blue color.

Special instructions

Do not exceed the dosage indicated in the instructions. To reduce the risk of gastrointestinal adverse events, the minimum effective dose should be used in the shortest possible course.

If the pain and fever persist or become worse, you should consult a doctor.

Patients with bronchial asthma, blood clotting disorders, or hypersensitivity to other analgesics should consult their doctor before taking Nalgesin®.

Caution should be exercised in patients with liver disease and renal insufficiency. In patients with renal insufficiency, creatinine clearance should be monitored. When creatinine clearance is less than 30 ml/min, naproxen is not recommended. In chronic alcoholic and other forms of liver cirrhosis, the concentration of unbound naproxen increases, so lower doses are recommended for such patients. After two weeks of using the drug, monitoring of liver function indicators is necessary.

Nalgesin® should not be taken together with other anti-inflammatory and analgesic medications, except as prescribed by a doctor.

Lower doses are also recommended for elderly patients.

You should avoid taking naproxen for 48 hours before surgery. If it is necessary to determine 17-corticosteroids, the drug should be discontinued 48 hours before the study. Similarly, naproxen may affect the determination of 5-hydroxyindoleacetic acid in the urine.

The use of naproxen, as well as other drugs that block prostaglandin synthesis, can affect fertility, so it is not recommended for women planning pregnancy.

Each tablet of Nalgesin® contains approximately 25 mg of sodium. When limiting salt intake, this should be taken into account.

Influence on the ability to drive vehicles and mechanisms

Naproxen slows down the reaction rate in patients. This should be taken into account when driving a car and performing tasks that require increased attention.
