Rimantadine (Tablets, Syrup) Instructions for Use

ATC Code

J05AC02 (Rimantadine)

Active Substance

Rimantadine (Rec.INN registered by WHO)

Clinical-Pharmacological Group

Antiviral drug

Pharmacotherapeutic Group

Systemic antiviral agents; direct-acting antiviral agents; cyclic amines

Pharmacological Action

Antiviral agent, an adamantane derivative; active against various strains of influenza A virus (especially type A2). The polymeric structure provides long-term circulation of rimantadine in the body, allowing its use not only for therapeutic but also for prophylactic purposes. It suppresses the early stage of specific replication (after the virus enters the cell and before initial RNA transcription).

Being a weak base, Rimantadine acts by increasing the pH of endosomes – membrane-bound vacuoles that surround viral particles after they enter the cell. Preventing acidification in these vacuoles blocks the fusion of the viral envelope with the endosome membrane, thus preventing the transfer of viral genetic material into the cell cytoplasm. Rimantadine also inhibits the release of viral particles from the cell, i.e., interrupts the transcription of the viral genome.

Pharmacokinetics

After oral administration, it is slowly, almost completely absorbed in the intestine. Plasma protein binding is about 40%. Vd in adults is 17-25 L/kg, in children – 289 L. The concentration in nasal secretions is 50% higher than plasma concentration. The Cmax value after a single dose of 100 mg is 181 ng/mL, after 100 mg twice daily is 416 ng/mL. It is metabolized in the liver. T1/2 is 24-36 hours; excreted by the kidneys (15% unchanged, 20% as hydroxyl metabolites).

Indications

Early treatment and prevention of influenza A in adults and children (depending on the dosage form).

ICD codes

ICD-10 code Indication
J10 Influenza due to identified seasonal influenza virus
Z29.8 Other specified prophylactic measures
ICD-11 code Indication
1E30 Influenza due to identified seasonal influenza virus
QC05.Z Prophylactic measures, unspecified

Dosage Regimen

The method of application and dosage regimen for a specific drug depend on its form of release and other factors. The optimal dosage regimen is determined by the doctor. It is necessary to strictly adhere to the compliance of the dosage form of a specific drug with the indications for use and dosage regimen.

Administer orally. Initiate treatment within 24-48 hours of influenza symptom onset for maximum therapeutic benefit.

For treatment of influenza A in adults: take 100 mg twice daily. A single daily dose of 100 mg may be used for patients with a high risk of side effects.

For prophylaxis of influenza A in adults: take 100 mg once daily. Continue dosing for at least 10 days following known exposure; continue for up to 6 weeks during community outbreaks.

For pediatric patients (7-10 years): administer 50 mg twice daily for treatment. For prophylaxis, administer 50 mg once daily.

For pediatric patients (1-6 years): administer the syrup formulation at a dose of 2.5 mg per kg of body weight once daily. The maximum daily dose must not exceed 50 mg.

In patients with severe hepatic impairment or epilepsy, the total daily dose must not exceed 100 mg.

For geriatric patients, use the lower end of the dosing range due to potential for reduced renal function and increased risk of adverse effects.

The total duration of therapy for influenza treatment is typically 5-7 days.

Adverse Reactions

From the cardiovascular system: tachycardia, heart failure, heart block, palpitations, arterial hypertension, cerebrovascular accident, loss of consciousness.

From the nervous system: insomnia, dizziness, headache, irritability, feeling of fatigue, impaired concentration, movement disorders, drowsiness, depressed mood, euphoria, hyperkinesia, tremor, hallucinations, confusion, convulsions.

From the sensory organs: tinnitus, change or loss of smell.

From the respiratory system: shortness of breath, bronchospasm, cough.

From the digestive system: nausea, vomiting, loss of appetite, dry oral mucosa, abdominal pain, diarrhea, dyspepsia.

From the skin and subcutaneous tissues: rash.

Other: allergic reactions.

Contraindications

Hypersensitivity to rimantadine; acute liver diseases, acute and chronic kidney diseases, thyrotoxicosis; pregnancy, breastfeeding period; childhood – depending on the dosage form used.

With caution in arterial hypertension, epilepsy (including history), cerebral atherosclerosis, in hepatic insufficiency, in gastrointestinal diseases; in elderly patients.

Use in Pregnancy and Lactation

Contraindicated for use during pregnancy. If use during lactation is necessary, the issue of discontinuing breastfeeding should be decided.

Use in Hepatic Impairment

Contraindicated in acute liver diseases.

Use in Renal Impairment

Contraindicated in acute and chronic kidney diseases.

Pediatric Use

Can be used in children of appropriate age categories strictly according to indications, in recommended doses and dosage forms. It is necessary to strictly follow the instructions in the rimantadine drug leaflets regarding contraindications for the use of specific rimantadine dosage forms in children of different ages.

Geriatric Use

In elderly patients with arterial hypertension, the risk of hemorrhagic stroke increases.

Special Precautions

When using rimantadine, exacerbation of chronic concomitant diseases is possible. In elderly patients with arterial hypertension, the risk of hemorrhagic stroke increases. In patients with a history of epilepsy and anticonvulsant therapy, the risk of an epileptic seizure increases while using rimantadine. In such cases, Rimantadine is used at a dose of up to 100 mg/day simultaneously with anticonvulsant therapy.

Prophylactic use is effective after contact with sick persons, when the infection spreads in closed groups, and when there is a high risk of disease during an influenza epidemic. The emergence of viruses resistant to the drug is possible.

The emergence of viruses resistant to rimantadine is possible.

For influenza caused by virus B, Rimantadine has an antitoxic effect.

Effect on ability to drive vehicles and machinery

Patients who experience dizziness, headache, or other side effects from the central nervous system while using rimantadine should exercise caution when driving vehicles and machinery, as well as when engaging in other potentially hazardous activities that require increased concentration and speed of psychomotor reactions.

Drug Interactions

With simultaneous use, Rimantadine reduces the effectiveness of anticonvulsant drugs.

Adsorbents, astringents, and coating agents reduce the absorption of rimantadine.

Agents that acidify urine (ammonium chloride, ascorbic acid) reduce the effectiveness of rimantadine (due to increased renal excretion).

Agents that alkalize urine (acetazolamide, sodium bicarbonate) enhance its effectiveness (by reducing renal excretion).

Paracetamol and acetylsalicylic acid reduce the Cmax of rimantadine by 11%.

Cimetidine reduces the clearance of rimantadine by 18%.

Storage Conditions

Store at 2°C (36°F) to 25°C (77°F). Keep in original packaging, protected from light. Keep out of reach of children.

Dispensing Status
