Pharmacological action

Combination drug whose action caused by components that are part of it.

Ornidazole is Antiprotozoal and antibacterial agent, a derivative of 5-nitroimidazole. The mechanism of action consists in biochemical restoration of 5-nitro group of Ornidazole intracellular transport proteins anaerobic bacteria and protozoa. Restored 5-nitro group of Ornidazole interacts with DNA cells of microorganisms by inhibiting the synthesis of their nucleic acids, leading to death of bacteria.

Active against Trichomonas vaginalis, Giardia lamblia, Entamoeba histolytica, as well as anaerobes Bacteroides spp. (including Bacteroides fragilis, Bacteroides distasonis, Bacteroides ovatus, Bacteroides thetaiotaomicron, Bacteroides vulgatus), Fusobacterium spp., Clostridium spp. To Ornidazole is not sensitive aerobic microorganisms.

Ofloxacin is an antimicrobial agent broad spectrum of action of the fluoroquinolone group, which acts on the bacterial enzyme DNA girazu providing sverzellati and thus the stability of the DNA of bacteria (destabilization of the DNA strands leads to their death). Has a bactericidal effect.

Antimicrobial spectrum includes gram-positive aerobes:Staphylococcus aureus (methicillin sensitive), Staphylococcus epidermidis (methicillin sensitive), Staphylococcus saprophyticus, Streptococcus pneumoniae (penicillin sensitive), Streptococcus pyogenes.

Gram-negative aerobes: Acinetobacter calcoaceticus, Bordetella pertussis, Citrobacter freundii, Citrobacter koseri, Enterobacter aerogenes, Enterobacter cloacae, Escherichia coli, Haemophilus ducreyi, Haemophilus influenzae, Klebsiella oxytoca, Moraxella catarrhalis, Morganella morganii, Klebsiella pneumoniae, Neisseria gonorrhoeae, Proteus mirabilis, Proteus vulgaris, Providencia rettgeri, Providencia stuartii, Pseudomonas aeruginosa (quickly develop resistance), Serratia marcescens.

Anaerobes: Clostridium perfringens.

Other: Chlamydia trachomatis, Chlamydia pneumoniae, Gardnerella vaginalis, Legionella pneumophila, Mycoplasma hominis, Mycoplasma pneumoniae, Ureaplasma urealyticum.

In most cases insensitive: Nocardia asteroides, anaerobic bacteria (including Bacteroides spp. Peptococcus spp., Peptostreptococcus spp., Eubacterium spp., Fusobacterium spp., Clostridium difficile), Enterococcus spp., most Streptococcus spp. no effect on Treponema pallidum.

Pharmacokinetics

Suction:

Like ofloxacin and Ornidazole are well absorbed from the gastrointestinal tract after oral administration. Bioavailability is 90% (Ornidazole) - 95% (ofloxacin). Connection with plasma proteins - 13% (Ornidazole) - 25% (ofloxacin). Dmah - 1-2 h, Ornidazole - 3 hours.

Distribution:

Ofloxacin: the apparent volume of distribution - 100 l. Distribution: cells (leukocytes, alveolar macrophages), skin, soft tissue, bone, abdominal organs and pelvis, respiratory system, urine, saliva, bile, prostate secretion, it permeates through the GEB, the placental barrier, is secreted with breast milk. Penetrates into the cerebrospinal fluid - 14-60%.

Ornidazole: penetrates into most tissues, passes through GEB and placenta, enters breast milk.

Metabolism and excretion:

Ofloxacin: it is metabolized in the liver (about 5%) with the formation of N-oxaloplatin and dimetilsiloksana. T1/2 - 4.5-7 h (independent of dose). Excreted by the kidneys - 75-90% (unchanged), 4% - in the bile. Extrarenal clearance of less than 20%. After a single application at a dose of 200 mg in the urine is detected for 20 to 24 h. In renal/hepatic insufficiency, the excretion may slow down. Not koumouliruet. During hemodialysis is removed 10-30% of the drug.

Ornidazole: it is metabolized in the liver by hydroxylation, oxidation and glukuronirovania. T1/2 is 12-14 hours Excreted as metabolites (60-70%) and unchanged (4%) kidney and intestine (20-25%), accumulates.

Dosage

Inside, 1 hour before meals or 2 hours after a meal, squeezed enough water. You should not crush, chew or break the tablet.

The recommended dose of 1 tablet 2 times a day for 7-10 days.

The dosing regimen in CKD (calculation of dose ofloxacin): KK 50-20 ml/min - 200 mg 1 time every 24 hours, when KK less 20 ml/min with hemodialysis, peritoneal dialysis - 200 mg 1 time every 48 hours.

When liver failure maximum daily dose - 2 tablets (400 mg of ofloxacin).

Overdose

Symptoms: dizziness, confusion, lethargy, disorientation, drowsiness, vomiting, epileptiform convulsions, depression, peripheral neuritis.

Treatment: gastric lavage, symptomatic treatment (diazepam - if spasms).

Drug interactions

Ofloxacin:

Decreases the clearance of theophylline by 25% (while the application should reduce the dose of theophylline).

Increases concentration glibenklamida plasma. Increases serum concentration of cyclosporine.

Zimetidin, furosemide, methotrexate and drugs (drugs) block tubular secretion, increase the concentration of ofloxacin in blood plasma. The simultaneous administration with indirect anticoagulants (coumarin derivatives including warfarin), it is necessary to control blood coagulation system. In appointing non-steroidal anti-inflammatory drugs, derivatives of nitroimidazole and methylxanthines increases the risk of neurotoxic effects, including seizures.

When concomitant administration with corticosteroids increases the risk of tendon rupture, especially in elderly people.

In the appointment with the PM, alkalizing the urine (carbonic anhydrase inhibitors, citrates, sodium bicarbonate), increasing the risk of crystalluria and nephrotoxic effects. While the appointment of hypoglycemic agents is possible both Hypo-and hyperglycemia, therefore it is necessary to control the concentration of glucose in the blood plasma.

While the use of drugs, lengthening of Q-T interval antiarrhythmic IA and III class, tricyclic and tetracyclic antidepressants, neuroleptics, macrolides, anti-fungal, some antihistamines, including astemizole, terfenadine, ebastine) may prolongation of the interval Q-T. foods, the antacids containing ions of aluminium, calcium, magnesium or iron salts reduce the absorption of ofloxacin, forming insoluble complexes (the time interval between administration of these drugs should be at least 2 hours).

Ornidazole:

Enhances the effect of indirect anticoagulants of kumarinovy number, prolongs the muscle relaxant effect of vecuronium bromide.

Compatible with ethanol (not inhibits acetyldihydrocodeinone) unlike other imidazole derivatives (metronidazole).
