pharmachologic effect

A broad-spectrum antimicrobial agent, a fluoroquinolone derivative.

Suppresses bacterial DNA gyrase (topoisomerases II and IV, responsible for the process of supercoiling of chromosomal DNA around nuclear RNA, which is necessary for reading genetic information), disrupts DNA synthesis, growth and division of bacteria; causes pronounced morphological changes (including the cell wall and membranes) and rapid death of the bacterial cell.

It has a bactericidal effect on gram-negative organisms during dormancy and division (because it affects not only DNA gyrase, but also causes lysis of the cell wall), on gram-positive microorganisms - only during the period of division.

Low toxicity for cells of a macroorganism is explained by the absence of DNA gyrase in them. While taking ciprofloxacin, there is no parallel development of resistance to other antibiotics that do not belong to the group of gyrase inhibitors, which makes it highly effective against bacteria that are resistant, for example, to aminoglycosides, penicillins, cephalosporins, tetracyclines and many other antibiotics.

Gram-negative aerobic bacteria are sensitive to ciprofloxacin: enterobacteria (Escherichia coli, Salmonella spp., Shigella spp., Citrobacter spp., Klebsiella spp., Enterobacter spp., Proteus mirabilis, Proteus alwards. , Morganella morganii, Vibrio spp., Yersinia spp.), Other gram-negative bacteria (Haemophilus spp., Pseudomonas aeruginosa, Moraxella catarrhalis, Aeromonas spp., Pasteurella multocida, Plesiomonas shigelloides, Campylobacter, jejunella spp.) pneumophila, Brucella spp., Chlamydia trachomatis, Listeria monocytogenes, Mycobacterium tuberculosis, Mycobacterium kansasii, Corynebacterium diphtheriae); gram-positive aerobic bacteria: Staphylococcus spp. (Staphylococcus aureus,Staphylococcus haemolyticus, Staphylococcus hominis, Staphylococcus saprophyticus), Streptococcus spp. (Streptococcus pyogenes, Streptococcus agalactiae).

Most methicillin-resistant staphylococci are also resistant to ciprofloxacin. The sensitivity of Streptococcus pneumoniae, Enterococcus faecalis, Mycobacterium avium (located intracellularly) is moderate (high concentrations are required to suppress them).

Resistant to the drug: Bacteroides fragilis, Pseudomonas cepacia, Pseudomonas maltophilia, Ureaplasma urealyticum, Clostridium difficile, Nocardia asteroides. Ineffective against Treponema pallidum.

Resistance develops extremely slowly, because on the one hand, after the action of ciprofloxacin, there are practically no persistent microorganisms, and on the other hand, bacterial cells do not have enzymes that inactivate it.

Pharmacokinetics

After oral administration, ciprofloxacin is rapidly absorbed mainly from the small intestine. Cmax in blood plasma is achieved after 1-2 hours. Bioavailability is about 70-80%. Plasma Cmax and AUC values ??increase in proportion to the dose.

After intravenous administration, Cmax) of ciprofloxacin is achieved at the end of the infusion. When administered intravenously, the pharmacokinetics of ciprofloxacin is linear in the dose range up to 400 mg. With the on / in the introduction 2-3 times / day, there was no accumulation of ciprofloxacin and its metabolites.

Plasma protein binding of ciprofloxacin is 20-30%; the active substance is present in blood plasma mainly in a non-ionized form. Ciprofloxacin is freely distributed in tissues and body fluids. Vd in the body is 2-3 l / kg. The concentration of ciprofloxacin in the tissues is significantly higher than the concentration in the blood serum. It is metabolized in the liver. Four metabolites of ciprofloxacin can be found in the blood in small concentrations: diethylcyprofloxacin (Ml), sulfocyprofloxacin (M2), oxocyprofloxacin (M3), formylcyprofloxacin (M4), three of which (Ml-M3) exhibit antibacterial activity in vitro, comparable to antibacterial activity acid. The in vitro antibacterial activity of the M4 metabolite, present in a smaller amount, is more consistent with the activity of norfloxacin.Ciprofloxacin is excreted mainly by the kidneys by glomerular filtration and tubular secretion; a small amount - through the digestive tract. Renal clearance is 0.18-0.3 l / h / kg, total clearance is 0.48-0.60 l / h / kg. Approximately 1% of the administered dose is excreted in the bile. In bile, ciprofloxacin is present in high concentrations. In patients with unchanged renal function, T1 / 2 is usually 3-5 hours. With impaired renal function, T1 / 2 increases.In patients with unchanged renal function, T1 / 2 is usually 3-5 hours. With impaired renal function, T1 / 2 increases.In patients with unchanged renal function, T1 / 2 is usually 3-5 hours. With impaired renal function, T1 / 2 increases.

In elderly patients, ciprofloxacin should be used in lower doses, depending on the severity of the disease and CC.

special instructions

When treating severe infections, staphylococcal infections and infections caused by anaerobic bacteria, ciprofloxacin should be used in combination with appropriate antibacterial agents.

Ciprofloxacin is not recommended for the treatment of Streptococcus pneumoniae infections due to its limited efficacy against the pathogen.

For genital infections suspected to be caused by fluoroquinolone-resistant strains of Neisseria gonorrhoeae, information on local resistance to ciprofloxacin should be considered and the susceptibility of the pathogen confirmed by laboratory tests.

Resistance to fluoroquinolones of Escherichia coli, the most common pathogenic microorganism causing urinary tract infections, varies by region of the Russian Federation. When prescribing, it is recommended to take into account the local prevalence of Escherichia coli resistance to fluoroquinolones.

Ciprofloxacin has an effect on the prolongation of the QT interval. Given that women have a longer average QT interval compared to men, they are more sensitive to drugs that cause QT interval prolongation. Elderly patients also have an increased sensitivity to the action of drugs that cause prolongation of the QT interval. Caution should be exercised when using ciprofloxacin in combination with drugs that prolong the QT interval (eg, class IA and III antiarrhythmics, tricyclic antidepressants, macrolides, and antipsychotics) or in patients at increased risk of QT interval prolongation or pirouette arrhythmias (eg, with congenital QT prolongation syndrome, corrected electrolyte imbalance,such as hypokalemia or hypomagnesemia, as well as with heart diseases such as heart failure, myocardial infarction, bradycardia).

Sometimes, after taking the first dose of ciprofloxacin, hypersensitivity reactions may develop, incl. allergic reactions. In rare cases, after the first use, anaphylactic reactions may occur, up to anaphylactic shock. In these cases, the use of ciprofloxacin should be stopped immediately and appropriate treatment carried out.

If severe and prolonged diarrhea occurs during or after treatment with ciprofloxacin, the diagnosis of pseudomembranous colitis should be excluded, which requires immediate discontinuation of the drug and the appointment of appropriate treatment (vancomycin orally at a dose of 250 mg 4 times / day). In this situation, the use of drugs that suppress intestinal motility is contraindicated.

With the use of ciprofloxacin, there have been cases of liver necrosis and life-threatening liver failure. If you have the following signs of liver disease, such as anorexia, jaundice, dark urine, itching, painful abdomen, ciprofloxacin should be discontinued. In patients taking ciprofloxacin and having had liver disease, there may be a temporary increase in the activity of hepatic transaminases and alkaline phosphatase or cholestatic jaundice.

Ciprofloxacin should be used with caution in patients with severe myasthenia gravis. possible exacerbation of symptoms.

At the first signs of tendinitis (painful swelling in the joint area, inflammation), the use of ciprofloxacin should be discontinued, physical activity should be excluded, because there is a risk of tendon rupture, and consult a doctor. When taking ciprofloxacin, there may be cases of tendonitis and tendon rupture (mainly the Achilles tendon), sometimes bilaterally, already within the first 48 hours after the start of therapy. Inflammation and rupture of the tendon may occur even several months after stopping ciprofloxacin treatment. Elderly patients, patients with renal insufficiency, patients after organ transplantation, while receiving treatment with corticosteroids, there is an increased risk of tendinopathy. Ciprofloxacin should be used with caution in patientswith a history of indications of tendon diseases associated with the intake of quinolones.

Ciprofloxacin, like other fluoroquinolones, can induce seizures and lower the seizure threshold. For patients with epilepsy and previous CNS diseases (for example, a decrease in the seizure threshold, a history of seizures, cerebrovascular accident, organic brain damage or stroke) due to the threat of CNS side reactions, ciprofloxacin should be used only in cases where when the expected clinical effect outweighs the possible risk of side effects. If seizures occur, the use of ciprofloxacin should be discontinued.

Mental reactions may occur even after the first use of fluoroquinolones, including ciprofloxacin. In rare cases, depression or psychotic reactions can progress to suicidal thoughts and suicidal attempts, incl. completed. In case of development of any side effects from the central nervous system, including mental disorders, it is necessary to immediately discontinue ciprofloxacin and begin appropriate therapy. In these cases, it is recommended to switch to therapy with an antibiotic other than fluoroquinolones, if possible.

Cases of sensory or sensorimotor polyneuropathy, hypoesthesia, dysesthesia, or weakness have been reported in patients taking fluoroquinolones, including ciprofloxacin. If symptoms such as pain, burning, tingling, numbness, weakness occur, patients should inform the doctor before continuing to use the drug.

When taking ciprofloxacin, a photosensitization reaction may occur, therefore patients should avoid contact with direct sunlight and UV light. Treatment should be discontinued if symptoms of photosensitivity are observed (for example, skin changes resemble sunburn).

Ciprofloxacin is known to be a moderate inhibitor of CYP1A2 isoenzymes. Care should be taken with the simultaneous use of ciprofloxacin and drugs metabolized by these enzymes, such as theophylline, methylxanthine, caffeine, duloxetine, ropinirole, clozapine, olanzapine, agomelatine. an increase in the concentration of these drugs in the blood serum, due to the inhibition of their metabolism by ciprofloxacin, can cause specific adverse reactions. The simultaneous use of ciprofloxacin and tizanidine is contraindicated.

In order to avoid the development of crystalluria, it is unacceptable to exceed the recommended daily dose; it is also necessary to have sufficient fluid intake and maintain an acidic urine reaction.

Under in vitro conditions, ciprofloxacin can interfere with the bacteriological study of Mycobacterium tuberculosis, inhibiting its growth, which can lead to false negative results when diagnosing this pathogen in patients taking ciprofloxacin.

As with other fluoroquinolones, the use of ciprofloxacin may change the concentration of glucose in the blood, including hypo- and hyperglycemia. Against the background of therapy with ciprofloxacin, dysglycemia may more often occur in elderly patients and patients with diabetes mellitus receiving concomitant therapy with oral hypoglycemic drugs (for example, sulfonylureas) or insulin. When using ciprofloxacin in such patients, the risk of developing hypoglycemia, up to hypoglycemic coma, increases. It is necessary to inform patients about the symptoms of hypoglycemia (confusion, dizziness, increased appetite, headache, nervousness, palpitations or increased heart rate, pallor of the skin, perspiration, trembling, weakness). If the patient develops hypoglycemia,it is necessary to immediately stop treatment with ciprofloxacin and initiate appropriate therapy. In these cases, it is recommended to switch to therapy with an antibiotic other than fluoroquinolones, if possible. When treating with ciprofloxacin in elderly patients, in patients with diabetes mellitus, careful monitoring of blood glucose concentration is recommended.

ѕо данным эпидемиологических исследований сообщалось о повышенном риске развити¤ аневризмы аорты и расслоени¤ аорты после приема фторхинолонов, особенно у пациентов пожилого возраста.

¬ св¤зи с этим фторхинолоны следует примен¤ть только после тщательной оценки соотношени¤ польза/риск и рассмотрени¤ других вариантов терапии у пациентов с аневризмой аорты в семейном анамнезе или у пациентов с диагностированной аневризмой аорты и/или расслоением аорты или при наличии других факторов риска или состо¤ний, предрасполагающих к развитию аневризме аорты или расслоени¤ аорты (например, синдром ћарфана, синдром Ёлерса-?анлоса сосудистого типа, артериит “ака¤су, гигантоклеточный артериит, болезнь Ѕехчета, артериальна¤ гипертензи¤, атеросклероз).

¬ случае внезапной боли в животе, груди или спине пациентам следует немедленно обратитьс¤ к врачу в отделение неотложной помощи.

¬ли¤ние на способность к управлению транспортными средствами и механизмами

‘торхинолоны, включа¤ ципрофлоксацин, могут нарушать способность пациентов управл¤ть автомобилем и заниматьс¤ другими потенциально опасными видами де¤тельности, требующими повышенного внимани¤ и быстроты психомоторных реакций, вследствие вли¤ни¤ на ?Ќ—.

Ћекарственное взаимодействие

—ледует соблюдать осторожность при одновременном применении ципрофлоксацина, как и других фторхинолонов, пациентам, получающим лекарственные препараты, вызывающие удлинение интервала QT (например, антиаритмические препараты класса I ј или класса III, трициклические антидепрессанты, макролиды, антипсихотические препараты).

ќдновременный прием ципрофлоксацина внутрь и катионсодержащих препаратов, минеральных добавок, содержащих кальций, магний, алюминий, железо, сукральфата, антацидов, полимерных фосфатных соединений (таких как севеламер, карбонат лантана) и препаратов с большой буферной емкостью (таких как таблетки диданозина), содержащих магний, алюминий или кальций, снижает всасывание ципрофлоксацина. ¬ таких случа¤х ципрофлоксацин следует принимать либо за 1-2 ч до, либо через 4 ч посл еприема этих препаратов.

Ёто ограничение не относитс¤ к лекарственным блокаторам гистминовых Ќ2-рецепторов.

ћетоклопрамид ускор¤ет всасывание ципрофлоксацина (при приеме внутрь), что приводит к более короткому времени достижени¤ Cmax ципрофлоксацина в плазме. ¬ли¤ни¤ на биодоступность ципрофлоксацина обнаружено не было.

ѕри одновременном применении ципрофлоксацина и омепразола, может отмечатьс¤ незначительное снижение Cmax в плазме и уменьшение AUC.

ќдновременное применение ципрофлоксацина и теофиллина может вызвать нежелательное повышение концентрации теофиллина в плазме крови и, соответственно, возникновение теофиллин-индуцированных неблагопри¤тных ¤влений; в очень редких случа¤х эти неблагопри¤тные ¤влени¤ могут быть угрожающими дл¤ жизни пациента. ?сли одновременное применение этих двух препаратов неизбежно, то рекомендуетс¤ проводить посто¤нный контроль концентрации теофиллина в плазме крови и, если необходимо, снизить дозу теофиллина.

ќдновременное применение ципрофлоксацина и кофеина или пентоксифиллина (окспентифиллин) может приводить к увеличению концентрации производных ксантина в сыворотке крови.

—очетание очень высоких доз хинолонов (ингибиторов ?Ќ -гиразы) и некоторых Ќѕ¬— (исключа¤ ацетилсалициловую кислоту) может провоцировать судороги.

ѕри одновременном применении ципрофлоксацина и препаратов, содержащих циклоспорин, наблюдалось кратковременное преход¤щее повышение концентрации креатинина в плазме крови. ¬ таких случа¤х необходимо 2 раза в неделю определ¤ть концентрацию креатинина в крови.

ѕри одновременном применении ципрофлоксацина и пероральных гипогликемических средств, главным образом, производных сульфонилмочевины (например, глибенкламида, глимепирида), развитие гипогликемии предположительно обусловлено усилением действи¤ пероральных гипогликемических средств (см. раздел Ђѕобочное действиеї).

ѕробенецид замедл¤ет скорость выведени¤ ципрофлоксацина почками. ќдновременное применение ципрофлоксацина и препаратов, содержащих пробенецид, приводит к повышению концентрации ципрофлоксацина в плазме крови.

ѕри одновременном применении ципрофлоксацина и фенитоина наблюдалось изменение (повышение или понижение) содержани¤ фенитоина в плазме крови. ¬о избежание ослаблени¤ противосудорожного эффекта фенитоина вследствие снижени¤ его концентрации, а также дл¤ предотвращени¤ нежелательных ¤влений, св¤занных с передозировкой фенитоином при прекращении приема ципрофлоксацина, рекомендуетс¤ осуществл¤ть контроль за терапией фенитоином у пациентов, принимающих оба препарата, включа¤ определение содержани¤ фенитоина в плазме крови в течение всего периода одновременного применени¤ обоих препаратов и непродолжительное врем¤ после завершени¤ комбинированной терапии.

ѕри одновременном применении метотрексата и ципрофлоксацина может замедл¤тьс¤ почечно-канальцевый транспорт метотрексата, что может сопровождатьс¤ повышением концентрации метотрексата в плазме крови. ѕри этом может увеличиватьс¤ веро¤тность развити¤ побочных эффектов метотрексата. ¬ св¤зи с этим за пациентами, получающими одновременную терапию метотрексатом и ципрофлоксацином, должно быть установлено тщательное наблюдение.

ѕри одновременном применении ципрофлоксацина и тизанидина наблюдалось увеличение концентрации тизанидина в сыворотке крови: увеличение —max в 7 раз (от 4 до 21 раза), увеличение AUC в 10 раз (от 6 до 24 раз). ”величение концентрации тизанидина в сыворотке крови может вызвать снижение ј? и сонливость. “аким образом, одновременное применение ципрофлоксацина и препаратов, содержащих тизанидин, противопоказано.

¬ ходе проведени¤ клинических исследований было показано, что одновременное применение дулоксетина и мощных ингибиторов изофермента CYP1ј2 (таких как флувоксамин), может привести к увеличению AUC и —mах дулоксетина. Ќесмотр¤ на отсутствие клинических данных о возможном взаимодействии с ципрофлоксацином, можно предвидеть веро¤тность подобного взаимодействи¤ при одновременном применении ципрофлоксацина и дулоксетина.

ќдновременное применение ропинирола и ципрофлоксацина, умеренного ингибитора изофермента CYP1ј2, приводит к увеличению —mах и AUC ропинирола на 60% и 84% соответственно. —ледует контролировать неблагопри¤тные эффекты ропинирола во врем¤ его совместного применени¤ с ципрофлоксацином и в течение короткого времени после завершени¤ комбинированной терапии.

¬ исследовании на здоровых добровольцах было установлено, что одновременное применение препаратов, содержащих лидокаин, и ципрофлоксацина, умеренного ингибитора изофермента CYP1ј2, приводит к снижению клиренса лидокаина на 22% при его в/в введении. Ќесмотр¤ на хорошую переносимость лидокаина при одновременном применении с ципрофлоксацином, возможно усиление побочных эффектов вследствие взаимодействи¤.

ѕри одновременном применении клозапина и ципрофлоксацина в дозе 250 мг в течение 7 дней, наблюдалось увеличение сывороточных концентраций клозапина и N-десметилклозапина на 29% и 31% соответственно. —ледует контролировать состо¤ние пациента и при необходимости проводить коррекцию режима дозировани¤ клозапина во врем¤ его совместного применени¤ с ципрофлоксацином и в течение короткого времени после завершени¤ комбинированной терапии.

ѕри одновременном применении у здоровых добровольцев ципрофлоксацина в дозе 500 мг и силденафила в дозе 50 мг, отмечалось увеличение —mах и AUC силденафила в 2 раза. ¬ св¤зи с этим применение данной комбинации возможно только после оценки соотношени¤ польза/риск.

ѕри одновременном приеме агомелатина и ципрофлоксацина можно ожидать аналогичных эффектов.

ѕри одновременном применении золпидема и ципрофлоксацина возможно повышение концентрации золпидема в плазме крови. ќдновременное применение препаратов, содержащих данные вещества, не рекомендуетс¤.

—овместное применение ципрофлоксацина и антагонистов витамина   (например, варфарина, аценокумарола, фенпрокумона) может приводить к усилению их антикоагул¤нтного действи¤. ¬еличина этого эффекта может измен¤тьс¤ в зависимости от сопутствующих инфекций, возраста и общего состо¤ни¤ пациента, поэтому сложно оценить вли¤ние ципрофлоксацина на увеличение ћЌќ. —ледует достаточно часто контролировать ћЌќ во врем¤ совместного применени¤ ципрофлоксацина и антагонистов витамина  , а также в течение короткого времени после завершени¤ комбинированной терапии.

Avoid the simultaneous use of ciprofloxacin and dairy products or beverages fortified with minerals (for example, milk, yogurt, calcium-fortified orange juice), as this may reduce the absorption of ciprofloxacin. However, calcium in other foods does not significantly affect the absorption of ciprofloxacin.
