PHARMACHOLOGIC EFFECT
Antimicrobial and antiprotozoal agent, synthetic derivative of nitroimidazole.
It is active against obligate anaerobic bacteria (sporo- and non-spore forming), pathogens of some protozoal infections: Trichomonas vaginalis, Giardia lamblia, Entamoeba histolytica.
Not active against aerobic bacteria.
Increases the sensitivity of tumors to radiation, causes sensitization to ethanol (disulfiram-like action). Interacts with DNA, causes disruption of the spiral structure, rupture of filaments, suppression of the synthesis of nucleic acids and cell death.
PHARMACOKINETICS
Secnidazole has a high degree of absorption, bioavailability is 80%. Metabolised in the liver. C max after a single oral intake of 2 g is achieved after 4 hours. It is excreted by the kidneys: within 72 hours - 16% of the accepted dose. Isolated with breast milk, penetrates the placental barrier.
INDICATIONS
Trichomonas urethritis and vaginitis, intestinal amebiasis, amebiasis of the liver, giardiasis.
DOSING MODE
For oral administration for adults, the dose is 2 g / day, for children - 30 mg / kg / day in one or more doses. The course of treatment is from 1 to 5 days.
SIDE EFFECT
Often: dyspeptic symptoms (including nausea, pain in the stomach), metallic taste in the mouth, glossitis, stomatitis, moderate reversible leukopenia, urticaria.
Rarely: dizziness, impaired coordination, ataxia, paresthesia, polyneuropathy.
CONTRAINDICATIONS
Organic diseases of the central nervous system, pathological changes in the pattern of peripheral blood (including in the anamnesis), pregnancy, lactation (breastfeeding), hypersensitivity to imidazole derivatives.
PREGNANCY AND LACTATION
Seknidazole is contraindicated in pregnancy and lactation (breastfeeding).
Penetrates through the placental barrier. Clinical data on safety of use in pregnancy are absent. In experimental studies, no teratogenic effect of secnidazole was detected.
Seknidazole is excreted in breast milk, so if it is necessary to use during lactation it is necessary to stop breastfeeding.
APPLICATION FOR CHILDREN
The application is possible according to the dosing regimen.
SPECIAL INSTRUCTIONS
During the treatment period, you should avoid drinking alcohol.
DRUG INTERACTION
When concomitant use of secnidazole with anticoagulants (coumarin or indanedione derivatives), the effect of the latter can be strengthened, therefore, prothrombin time should be monitored periodically and, if necessary, adjusted doses of anticoagulants.
With the simultaneous use of secnidazole with disulfiram, it is possible to develop paranoia and psychosis; with ethanol - it is possible to develop effects similar to the action of disulfiram (abdominal cramps, nausea, vomiting, headache, sudden rush of blood to the face).
It is not recommended to combine with nondepolarizing muscle relaxants (vecuronium bromide).
With simultaneous reception with lithium preparations, secnidazole increases its concentration in plasma.
When combined with amoxicillin, Helicobacter pylori activity increases (amoxicillin suppresses the development of resistance).
