Tiberal, 500 mg 10 pcs

Pharmacodynamics

Antiprotozoal, antibacterial.

Active against: Trichomonas vaginalis. Entamoeba histolytica. Giardia lamblia (Giardia intenstinalis). Some anaerobic bacteria (Bacteroides spp., Clostridium spp., Fusobacterium spp.) and anaerobic cocci.

Pharmacokinetics

Intake

After oral administration, Ornidazole is rapidly absorbed in the gastrointestinal tract. On average, absorption is 90%. Maximum plasma concentrations are reached within 3 hours.

Distribution

The binding of Ornidazole to proteins is about 13%. The active substance penetrates into the cerebrospinal fluid, other body fluids and tissues. Plasma concentrations of Ornidazole are in the range of 6-36 mg/l, which is the level considered optimal for various indications for the use of the drug. After multiple doses of 500 mg or 1000 mg in healthy volunteers every 12 hours, the cumulation factor is 1.5-2.5.

Metabolism

Ornidazole is metabolized in the liver to form mainly 2-hydroxymethyl – and α-hydroxymethylmetabolites. Both metabolites are less active against Trichomonas vaginalis and anaerobic bacteria than unchanged Ornidazole.

The elimination half-life is about 13 hours. After a single dose, 85% of the dose is excreted within the first 5 days, mainly as metabolites. About 4% of the dose taken is excreted unchanged through the kidneys.

Indications

Lung inflammation (pneumonia), Skin infections

• Trichomoniasis (urogenital infections in women and men caused by Trichomonas vaginalis);
• Giardiasis;
• Prevention of anaerobic infections during colorectal surgery and gynecological interventions.

Interaction

Ornidazole does not inhibit aldehyde dehydrogenase and therefore is not incompatible with alcohol.

Ornidazole, however, potentiates the effect of oral coumarin anticoagulants, which requires appropriate adjustment of their dose.

Ornidazole prolongs the myorelaxant effect of vecuronium bromide.

Special Instructions

.

Overdose

Symptoms: side effects develop, but in a more pronounced form.
