pharmachologic effect

Antimicrobial agent from the group of fluoroquinolones, acts bactericidal. Shows activity against a wide range of gram-positive and gram-negative microorganisms, anaerobic, acid-fast and atypical bacteria: Mycoplasma spp., Chlamydia spp., Legionella spp. Effective against bacterial strains resistant to beta-lactams and macrolides. It is active against most strains of microorganisms: gram-positive - Staphylococcus aureus (including strains insensitive to methicillin), Streptococcus pneumoniae (including strains resistant to penicillin and macrolides), Streptococcus pyogenes (group A); gram-negative - Haemophilus influenzae (including both ?-lactamase-producing and non-?-lactamase-producing strains), Haemophilus parainfluenzae, Klebsiella pneumoniae, Moraxella catarrhalis (including both producing,strains not producing ?-lactamase), Escherichia coli, Enterobacter cloacae; atypical - Chlamydia pneumoniae, Mycoplasma pneumoniae. According to in vitro studies, although the microorganisms listed below are sensitive to moxifloxacin, nevertheless, its safety and efficacy in the treatment of infections has not been established. Gram-positive microorganisms: Streptococcus milleri, Streptococcus mitior, Streptococcus agalactiae, Streptococcus dysgalactiae, Staphylococcus cohnii, Staphylococcus epidermidis (including strains susceptible to methicillin), Staphylococcus hemolyticus. Gram-negative microorganisms: Bordetella pertussis, Klebsiella oxytoca, Enterobacter aerogenes, Enterobacter agglomerans, Enterobacter intermedius,Enterobacter sakazaki, Proteus mirabilis, Proteus vulgaris, Morganella morganii, Providencia rettgeri, Providencia stuartii.

Blocks topoisomerases II and IV, enzymes that control the topological properties of DNA, and are involved in DNA replication, repair and transcription. The action of moxifloxacin depends on its concentration in blood and tissues. The minimum bactericidal concentrations are almost indistinguishable from the minimum inhibitory concentrations.

The mechanisms of development of resistance, inactivating penicillins, cephalosporins, aminoglycosides, macrolides and tetracyclines, do not affect the antibacterial activity of moxifloxacin. There is no cross-resistance between moxifloxacin and these drugs. No plasmid-mediated mechanism of resistance development was observed. The overall incidence of resistance is low. In vitro studies have shown that resistance to moxifloxacin develops slowly as a result of a series of successive mutations. With repeated exposure to microorganisms with subminimal inhibitory concentrations of moxifloxacin, the MIC values ??only slightly increase. Cross-resistance is observed between drugs from the fluoroquinolone group. However, some gram-positive and anaerobic microorganisms resistant to other fluoroquinolones,sensitive to moxifloxacin.

Pharmacokinetics

After oral administration, moxifloxacin is absorbed quickly and almost completely. The absolute bioavailability is about 91%. The pharmacokinetics of moxifloxacin when taken in a dose of 50 to 1200 mg once, as well as 600 mg / day for 10 days, is linear. After a single dose of moxifloxacin at a dose of 400 mg, Cmax in the blood is reached within 0.5-4 hours and is 3.1 mg / l. After oral administration of moxifloxacin at a dose of 400 mg 1 time / day, Cssmax and Cssmin are 3.2 mg / l and 0.6 mg / l, respectively.

special instructions

In some cases, after the first moxifloxacin, hypersensitivity and allergic reactions may develop, and the doctor should be immediately informed about this. Very rarely, even after the first use, anaphylactic reactions can progress to life-threatening anaphylactic shock. In these cases, treatment with moxifloxacin should be discontinued and the necessary therapeutic measures (including anti-shock) should be started immediately.

With caution in women and elderly patients. Because women have a longer QT interval compared to men, they may be more sensitive to drugs that prolong the QT interval. Elderly patients are also more susceptible to drugs that affect the QT interval.

The degree of lengthening of the QT interval may increase with increasing concentration of moxifloxacin, therefore, the recommended dose should not be exceeded. Prolongation of the QT interval is associated with an increased risk of ventricular arrhythmias, including polymorphic ventricular tachycardia.

The patient should be informed that in the event of symptoms of liver failure, symptoms of skin or mucous membrane lesions, symptoms of neuropathy (pain, burning, tingling, numbness or weakness), it is necessary to consult a doctor before continuing treatment with pmoxifloxacin.

The use of broad-spectrum antibacterial drugs, including moxifloxacin, is associated with the risk of developing pseudomembranous colitis. Drugs that inhibit intestinal motility are contraindicated in the development of severe diarrhea.

Against the background of quinolone therapy, incl. moxifloxacin, tendinitis and tendon rupture may develop, especially in the elderly and patients receiving GCS. Cases are described that occurred within a few months after the completion of treatment. At the first symptoms of pain or inflammation at the site of injury, the use of moxifloxacin should be discontinued and the affected limb should be relieved.

During the treatment period, exposure to direct sunlight and UV radiation should be avoided.

Moxifloxacin is not recommended for the treatment of methicillin-resistant strains of Staphylococcus aureus (MRSA). Suspected or confirmed MRSA infections should be treated with appropriate antibacterial drugs.

The ability of moxifloxacin to inhibit the growth of mycobacteria may cause in vitro interaction of moxifloxacin with a test for Mycobacterium spp., Leading to false negative results when analyzing samples from patients receiving moxifloxacin.

Mental reactions may occur even after the first administration of fluoroquinolones, including moxifloxacin. In very rare cases, depression or psychotic reactions progress to suicidal thoughts and self-harming behaviors, including suicidal attempts. If such reactions develop in patients, moxifloxacin should be discontinued and the necessary measures taken. Caution should be exercised when using moxifloxacin in patients with a history of psychosis and / or psychiatric illness.

Due to the widespread and increasing incidence of infections caused by fluoroquinolone-resistant Neisseria gonorrhoeae, moxifloxacin monotherapy should not be used in the treatment of patients with pelvic inflammatory disease, unless the presence of fluoroquinolone-resistant N. gonorrhoeae is excluded. If it is not possible to exclude the presence of fluoroquinolone-resistant N. gonorrhoeae, it is necessary to consider supplementing empiric therapy with moxifloxacin with an appropriate antibiotic that is active against N. gonorrhoeae (eg, cephalosporin).

During therapy with moxifloxacin, dysglycemia occurred mainly in elderly patients with diabetes mellitus receiving concomitant therapy with oral hypoglycemic drugs (for example, sulfonylureas) or insulin. When carrying out treatment in patients with diabetes mellitus, careful monitoring of blood glucose concentration is recommended.

Influence on the ability to drive vehicles and mechanisms

Fluoroquinolones, including moxifloxacin, can interfere with the ability of patients to drive and engage in other potentially hazardous activities that require increased attention and speed of psychomotor reactions due to the effect on the central nervous system and visual impairment.

Drug interactions

Consideration should be given to the possible additive effect of lengthening the QT interval of moxifloxacin and other drugs that affect the prolongation of the QT interval. Due to the combined use of moxifloxacin and drugs that affect the prolongation of the QT interval, the risk of developing ventricular arrhythmias, including polymorphic ventricular tachycardia of the 'pirouette' type, increases. The combined use of moxifloxacin with the following drugs that affect the prolongation of the QT interval is contraindicated: class IA antiarrhythmic drugs (including quinidine, hydroquinidine, disopyramide); class III antiarrhythmic drugs (including amiodarone, sotalol, dofetilide, ibutilide); antipsychotics (including phenothiazine, pimozide, sertindole, haloperidol, sultopride); tricyclic antidepressants; antimicrobial drugs (sparfloxacin, IV erythromycin, pentamidine,antimalarial drugs, especially halofantrine); antihistamines (terfenadine, astemizole, mizolastine); others (cisapride, vincamine IV, bepridil, diphemanil).

With the simultaneous ingestion of antacids, multivitamins and minerals, moxifloxacin absorption may be impaired due to the formation of chelate complexes with polyvalent cations contained in these preparations. As a result, the concentration of moxifloxacin in the blood plasma can be significantly lower than the therapeutic one. In this regard, antacids, antiretrovirals (for example, didanosine) and other drugs containing magnesium, aluminum, sucralfate, iron, zinc should be taken at least 4 hours before or 4 hours after oral administration of moxifloxacin.

In patients who received anticoagulants in combination with antibiotics, incl. with moxifloxacin, there have been cases of an increase in the anticoagulant activity of anticoagulant drugs. Risk factors are the presence of an infectious disease (and a concomitant inflammatory process), the age and general condition of the patient. Despite the fact that the interaction between moxifloxacin and warfarin is not detected, in patients receiving combined treatment with these drugs, it is necessary to monitor the INR and, if necessary, adjust the dose of indirect anticoagulants.

Moxifloxacin and digoxin do not significantly affect the pharmacokinetic parameters of each other. With repeated administration of moxifloxacin, the Cmax of digoxin increased by approximately 30%. In this case, the value of AUC and Cmin of digoxin does not change.

With the simultaneous use of activated carbon and moxifloxacin orally at a dose of 400 mg, the systemic bioavailability of the drug decreases by more than 80% as a result of slowing down its absorption. In case of an overdose, the use of activated carbon at an early stage of absorption prevents a further increase in systemic exposure.
