INSTRUCTION FOR THE SPECIALIST.
Description of the drug approved by the manufacturer for the printed edition of 2011.
Combined anti-tuberculosis drug.
Antimicrobial bactericide of broad spectrum of action from the group of fluoroquinolones. Affects the bacterial enzyme DNA-gyrase, which provides supercoiling, forms a complex with its tetramer (subunit of gyrase A2B2) and disrupts transcription and replication of DNA, leads to the death of the microbial cell.
Beta-lactamases, produced by pathogens, do not affect the activity of lomefloxacin. Highly active against Gram-negative aerobic microorganisms: Neisseria gonorrhoeae, Neisseria meningitidis, Escherichia coli, Citrobacter diversus, Klebsiella pneumoniae, Enterobacter cloacae, Proteus vulgaris, Salmonella spp, Shigella spp., Moraxella catarrhalis, Morganella morganii, Haemophilus influenzae and parainfluenzae, Legionella pneumophila , Pseudomonas aeruginosa. Moderately sensitive to the drug Staphylococcus aureus, Staphylococcus epidermidis, Serratia liguifaciens imarcescens, Pseudomonas aeruginosa, Mycobacterium tuberculosis, Chlamydia trachomatis, Hafnia alvei, Citrobacter freundii, Aeromonas hydrophila, Proteus mirabilis and Proteus stuartii, Providencia rettgeri and Providencia alcalifaciens, Klebsiella oxytoca, Klebsiella ozaenae , Enterobacter aerogenes, Enterobacter agglomerans. Resistant to the preparation Streptococcus spp ,, Pseudomonas cepacia, Ureaplasma urealyticum, Treponema pallidum, Mycoplasma hominis and anaerobic bacteria. It acts both on the extracellular and intracellular located Mycobacterium tuberculosis, shortens the time of their isolation from the body, provides a faster resorption of infiltrates. Most microorganisms act at low concentrations (the concentration necessary to control the growth of 90% of strains, usually not more than 1 Ојg / ml). Resistance is rare.
Pyrazinamide has a bactericidal action at acidic pH values. Well penetrates into the tuberculosis foci. Its activity is high in caseous-necrotic processes, caseous lymphadenitis, tuberculomas. It is subjected to enzymatic conversion into the active form - pyrazinic acid. At acidic pH values, the minimum inhibitory concentration of pyrazinamide in vitro is 20 mg / l. On non-tuberculosis pathogens does not work.
It blocks the synthesis of mycolic acids, which are an important structural component of the Mycobacterium tuberculosis cell wall, a nicotinic acid antagonist. In high concentrations acts bactericidal, disrupting the synthesis of the protein of the microbial cell. It is also effective against mycobacteria, resistant to anti-tuberculosis drugs of the first series. Affects both extracellular and intracellularly located mycobacteria. It is not very active against mycobacteria of bovine tuberculosis, atypical mycobacteria and acid-resistant saprophytes (the minimum suppressing concentration is 20-30 Ојg / ml). The pathogenic nonspecific flora does not work. Penetrates into cells, in particular macrophages. Has a bactericidal effect in an acidic environment. The development of resistance of mycobacterium tuberculosis to protionamide with monotherapy develops rapidly (after 2 months in 32%, 4 months - in 82%). With combined therapy, resistance can develop by 6 months (up to 15% ) .
Bacteriostatic drug, effective against typical and atypical mycobacteria tuberculosis. The mechanism of action of the drug is associated with a violation of the synthesis of RNA in bacterial cells, it suppresses the synthesis of the cell wall, blocking the inclusion of mycolic acids in it. Etambutol is active against rapidly and slowly growing atypical mycobacteria. The minimum inhibitory concentration of ethambutol is - 0.78-2.0 mg / l. Ethambutol does not act on nontuberculous pathogenic microorganisms.
Vitamin product. Participates in the metabolism. It is necessary for the normal functioning of the central and peripheral nervous system. With tuberculosis infection, there is a deficiency of pyridoxine. With the simultaneous administration of pyridoxine inwards with lomefloxacin, pyrazinamide and ethambutol, no interaction of these drugs is observed at the pharmacokinetic and microbiological levels. Reduces the neurotoxicity of anti-tuberculosis drugs.
Active components that are part of Proteb-5, do not affect the rate of absorption of Lomefloxacin from the gastrointestinal tract. Bioavailability of Lomefloxacin is more than 90%. The drug after intake is rapidly absorbed from the gastrointestinal tract. Cmax is 5.1 mg / l, the time to reach is 1-1.5 hours. It circulates for a long time in the body: the half-life is 8-9 hours. The connection with blood proteins is insignificant - 10%. Well penetrates into various organs and tissues, where concentrations are created, 9-13 times higher than serum. In small amounts, biotransformation is carried out in the liver with the formation of 5 metabolites, which have little antimicrobial activity. In 80% is excreted by the kidneys, in 20% - with feces, then with saliva. Hepatic failure does not affect the biotransformation of lomefloxacin.
Quickly and completely absorbed in the gastrointestinal tract. The connection with plasma proteins is 10-20%. TC max - 1-2 h. It penetrates well into tissues and organs.
Metabolised in the liver, where an active metabolite, pyrazinic acid, is first formed, which is then converted into an inactive metabolite, 5-hydroxypyrazinic acid. T 1/2- 8-9 hours.
It is excreted by the kidneys: in unmodified form - 3%, in the form of pyrazinic acid - 33%, in the form of other metabolites - Z6%. Removed during hemodialysis.
Absorption in the gastrointestinal tract is rapid. TC max - 2-3 hours. Easily penetrates into healthy and pathologically altered tissues (tubercular foci, caverns in the lungs, serous and purulent pleural effusion, cerebrospinal fluid with meningitis).
Metabolised in the liver (one of the metabolites - sulfoxide, has tuberculostatic activity). It is excreted by the kidneys and with bile (15-20% unchanged).
Absorption is high; bioavailability is 75-80%. After oral administration of a dose of 25 mg of TC max - 2-4 hours, C max of the drug in the blood - 1-5 Ојg / ml.Connection with plasma proteins - 20-30%.
It penetrates well into tissues and organs, as well as into biological fluids, with the exception of ascitic and pleural (in cerebrospinal fluid only with meningitis). The greatest concentrations are created in the kidneys, lungs, saliva, urine. Penetrates into breast milk. Do not pass through the intact blood-brain barrier.
Partially metabolized in the liver (15%) with the formation of inactive metabolites, T 1/2 - 3-4 hours ; when renal dysfunction is 8 hours. It is excreted by the kidneys - 80-90% (50% in unchanged form, 15% in the form of inactive metabolites) and with fecal masses - 10-20% (unchanged). It is excreted in hemodialysis and peritoneal dialysis.
Absorbed rapidly throughout the small intestine, a larger amount is absorbed in the jejunum. Metabolised in the liver with the formation of pharmacologically active metabolites (pyridoxal phosphate and pyridoxamine phosphate). Pyridoxal phosphate with plasma proteins binds to 90%. It penetrates well into all tissues; accumulates mainly in the liver, less - in the muscles and central nervous system. Penetrates through the placenta, is secreted with breast milk. The half-life is 15-20 days. It is excreted by the kidneys.

Lomefloxacin together with isoniazid, ethambutol and, especially, pyrazinamide, significantly increases antimicrobial activity against sensitive and especially resistant mycobacteria tuberculosis. The combined use of the drug with probenecid slows the management of lomefloxacin; with rifampicin leads to a decrease in antimicrobial activity of this combination against mycobacterium tuberculosis due to the antagonism existing between lomefloxacin and rifampicin at the microbial level. Sucralfate and antacid agents containing magnesium or aluminum ions form chelate-forming complexes with lomefloxacin. The interval between admission should be at least 2 hours before or after taking Lomefloxacin.
Prothionamide in combination with lomefloxacin significantly increases antimicrobial activity against mycobacteria tuberculosis. Antacids reduce the absorption of protionamide. Reduces the effectiveness of antihypertensive drugs.
Pyrazinamide increases the concentration of isoniazid in the serum, slowing its excretion. When taking rifampicin together with pyrazinamide, the risk of developing hepatotoxic reactions increases.
Aluminum hydroxide reduces the absorption of ethambutol. The administration of ethambutol with aminoglycosides, imipenem, carbamazepine, lithium salts, quinine increases the risk of neurotoxic action of the drug, and also enhances the antimicrobial activity of other antituberculous drugs.
Pyridoxine weakens the action of levodopa when combined.
Reduces the risk of toxic effects of antituberculosis drugs on the central and peripheral nervous system. Pyridoxine does not affect the antimicrobial activity of the preparations that make up Protub-5.
