Rezonisate^® (Capsules) Instructions for Use

ATC Code

J04AK03 (Terizidone)

Active Substance

Terizidone (Rec.INN WHO registered)

Clinical-Pharmacological Group

Antituberculosis drug

Pharmacotherapeutic Group

Antitubercular agent

Pharmacological Action

Bacteriostatic broad-spectrum antibiotic, active against Mycobacterium tuberculosis, Mycobacterium bovis, Mycobacterium avium, as well as Staphylococcus aureus and Staphylococcus epidermidis.

Also sensitive are: Enterococcus faecalis, Escherichia coli, Citrobacter spp., Enterobacter spp., Morganella morganii, Klebsiella pneumoniae and Pseudomonas aeruginosa.

The development of secondary resistance is rare. No cross-resistance with other antituberculosis drugs is observed.

Pharmacokinetics

Absorption from the gastrointestinal tract is 70-90% (food intake does not affect the rate of absorption). Time to reach C_max is 2-3 hours. Effective C_min: for Mycobacterium tuberculosis – 10-40 mg/L, for staphylococci – 8-32 mg/L, for gram-negative bacteria (of clinical significance) – 20-250 mg/L.

It is well distributed in body tissues and fluids ( lungs, bile, ascitic fluid, pleural effusion, synovial fluid, lymph, sputum).

Penetrates into the CSF ( 80-100% of the serum concentration), a higher concentration in the CSF is achieved with inflammatory changes in the meninges.

Metabolized to a minor extent.

T_1/2 – 21 hours. Excreted by the kidneys (unchanged – 60-70%), intestines (a small amount unchanged and as metabolites).

Indications

Tuberculosis of various forms and localizations as part of complex therapy for resistant forms of the disease.

In case of CrCl less than 30 ml/min, the dose and frequency of administration are reduced.

Adverse Reactions

From the nervous system: headache, dizziness, increased excitability, tremor, insomnia, feeling of intoxication; in isolated cases – epileptiform seizures, depression, psychosis.

From the digestive system: rarely – abdominal pain, flatulence, diarrhea.

Allergic reactions.

Geriatric Use

Special Precautions

Terizidone may cause cyanocobalamin and/or folic acid deficiency, appropriate examination and treatment are necessary.

Blood and urine parameters, liver function ( ALT, AST, bilirubin) should be monitored monthly.

Avoid consumption of ethanol, as simultaneous use with terizidone increases the frequency of side effects (up to the development of seizures).

Due to the possibility of developing side effects from the nervous system (depression, behavior change), it is necessary to monitor the patient’s mental status.

Effect on ability to drive vehicles and mechanisms

During treatment, it is necessary to refrain from driving vehicles and engaging in potentially hazardous activities that require increased concentration and speed of psychomotor reactions.

Drug Interactions

Ethanol increases the risk of epileptic seizures.

When used concomitantly with ethionamide, the risk of side effects from the CNS (especially seizures) increases.

Concomitant use with isoniazid increases the frequency of dizziness and drowsiness.

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.
