Взрослым и детям старше 10 лет — по 500 мг 3 раза в сутки; при тяжелом течении инфекции доза может быть повышена до 1000 мг 3 раза в сутки. Детям до 2 лет (в виде суспензии) — 20 мг/кг в сутки в 3 приема (по 1/4 ч.ложки), 2–5 лет — 125 мг (по 1/2 ч.ложки), 5–10 лет — 250 мг (по 1 ч.ложке или 1 капс.) 3 раза в день. При острой неосложненной гонорее — 3 г однократно.

Суспензию готовят путем добавления к сухому веществу кипяченой воды комнатной температуры до метки 100 мл и последующего взбалтывания.

В/м, в/в струйно и капельно. Для в/м введения раствор готовят ex tempore, добавляя к содержимому флакона (1 г) 3 мл воды для инъекций. Для в/в струйного введения дозу препарата (не более 2 г) растворяют в 10–20 мл 0,9% раствора натрия хлорида и вводят медленно в течение 3–5 мин. При разовой дозе, превышающей 2 г, препарат вводят в/в капельно.

Для в/в капельного введения разовую дозу (2–4 г) растворяют в 125–250 мл 0,9% раствора натрия хлорида или 5–10% раствора декстрозы (глюкозы) и вводят со скоростью 60–80 кап/мин (взрослым). При капельном введении детям в качестве растворителя используют 5% раствор декстрозы (глюкозы) (50–100 мл в зависимости от возраста) и вводят со скоростью 10 кап/мин. Раствор используют сразу после приготовления; недопустимо добавление к нему других лекарственных препаратов. Суточную дозу распределяют на 2–3 введения. Продолжительность в/в введения 5–7 дней, с последующим переходом, при необходимости, на в/м введение или прием препарата внутрь.

Длительность лечения зависит от формы и тяжести заболевания и составляет 5–14 дней и более.

Перед назначением следует определить чувствительность выделенного возбудителя.

Разовая доза для взрослых составляет 1–2 г, вводится каждые 8–12 ч (3–6 г/сут). Разовая доза для взрослых при в/м введении не должна превышать 1 г. Максимальная суточная доза для взрослых — 6 г.

Новорожденным, недоношенным и детям до 1 года препарат назначают в суточной дозе 100 мг/кг, детям остальных возрастных групп — 50 мг/кг. Разовая доза для детей при в/м введении — не выше 0,5 г.

При тяжелом течении инфекции указанные дозы для взрослых и детей могут быть увеличены в 1,5–2 раза. В этом случае препарат вводят в/в. Суточную дозу распределяют на 2–3 введения с интервалом 8–12 ч.

Для профилактики послеоперационных осложнений препарат вводят в/в за 30 мин или в/м за 1 ч до операции в дозе 0,5–1 г. Повторно в течение первых суток послеоперационного периода препарат применяют в той же дозе каждые 8–12 ч. При операциях на заведомо инфицированных областях продолжительность профилактического применения может быть увеличена до 3–5 дней.

При почечной недостаточности схемы лечения корректируют, уменьшая дозу или удлиняя интервал между введениями (24–48 ч). При Cl креатинина 10–30 мл/мин препарат вводят в суточной дозе 1 г, затем — по 0,5 г каждые 12 ч; при Cl креатинина менее 10 мл/мин — 1 г, затем по 0,5 г каждые 24 ч. У больных в состоянии анурии суточная доза не должна превышать 2 г.

< History of a severe immediate hypersensitivity reaction (e.g. anaphylaxis) to another beta-lactam agent (e.g. a cephalosporin, carbapenem or monobactam).

History of a severe immediate hypersensitivity reaction (e.g. anaphylaxis) to another beta-lactam agent (e.g. a cephalosporin, carbapenem or monobactam).

Hypersensitivity reactions

Before initiating therapy with Moxypen Forte, careful enquiry should be made concerning previous hypersensitivity reactions to penicillins, cephalosporins or other beta-lactam agents.

Serious and occasionally fatal hypersensitivity reactions (including anaphylactoid and severe cutaneous adverse reactions) have been reported in patients on penicillin therapy. These reactions are more likely to occur in individuals with a history of penicillin hypersensitivity and in atopic individuals. If an allergic reaction occurs, Moxypen Forte therapy must be discontinued and appropriate alternative therapy instituted.

Non-susceptible microorganisms

Moxypen Forte is not suitable for the treatment of some types of infection unless the pathogen is already documented and known to be susceptible or there is a very high likelihood that the pathogen would be suitable for treatment with Moxypen Forte. This particularly applies when considering the treatment of patients with urinary tract infections and severe infections of the ear, nose and throat.

Convulsions

Convulsions may occur in patients with impaired renal function or in those receiving high doses or in patients with predisposing factors (e.g. history of seizures, treated epilepsy or meningeal disorders.

Renal impairment

In patients with renal impairment the dose should be adjusted accordingly to the degree of impairment.

Skin reactions

The occurrence at the treatment initiation of a feverish generalised erythema associated with pustula may be a symptom of acute generalised exanthemous pustulosis. This reaction requires Moxypen Forte discontinuation and contra-indicates any subsequent administration.

Moxypen Forte should be avoided if infectious mononucleosis is suspected since the occurrence of a morbilliform rash has been associated with this condition following the use of Moxypen Forte.

Jarisch-Herxheimer reaction

The Jarisch-Herxheimer reaction has been seen following Moxypen Forte treatment of Lyme disease. It results directly from the bactericidal activity of Moxypen Forte on the causative bacteria of Lyme disease, the spirochaete Borrelia burgdorferi. Patients should be reassured that this is a common and usually self-limiting consequence of antibiotic treatment of Lyme disease.

Overgrowth of non-susceptible microorganisms

Prolonged use may also occasionally result in overgrowth of non-susceptible organisms.

Antibiotic-associated colitis has been reported with nearly all antibacterial agents and may range in severity from mild to life threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhoea during, or subsequent to, the administration of any antibiotics. Should antibiotic-associated colitis occur, Moxypen Forte should immediately be discontinued, a physician consulted and an appropriate therapy initiated. Anti-peristaltic medicinal products are contra-indicated in this situation.

Prolonged therapy

Periodic assessment of organ system functions; including renal, hepatic and haematopoietic function is advisable during prolonged therapy. Elevated liver enzymes and changes in blood counts have been reported.

Anticoagulants

Prolongation of prothrombin time has been reported rarely in patients receiving Moxypen Forte. Appropriate monitoring should be undertaken when anticoagulants are prescribed concomitantly. Adjustments in the dose of oral anticoagulants may be necessary to maintain the desired level of anticoagulation.

Crystalluria

In patients with reduced urine output, crystalluria has been observed very rarely, predominantly with parenteral therapy. During the administration of high doses of Moxypen Forte, it is advisable to maintain adequate fluid intake and urinary output in order to reduce the possibility of Moxypen Forte crystalluria. In patients with bladder catheters, a regular check of patency should be maintained.

Interference with diagnostic tests

Elevated serum and urinary levels of Moxypen Forte are likely to affect certain laboratory tests. Due to the high urinary concentrations of Moxypen Forte, false positive readings are common with chemical methods.

It is recommended that when testing for the presence of glucose in urine during Moxypen Forte treatment, enzymatic glucose oxidase methods should be used.

The presence of Moxypen Forte may distort assay results for oestriol in pregnant women.

Important Information about excipients

This medicinal product contains sucrose. Patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency should not take this medicine.

This medicinal product contains sodium benzoate (E211) which is a mild irritant to the eyes, skin and mucous membrane. May increase the risk of jaundice in new born babies.

Pharmacotherapeutic group: penicillins with extended spectrum; ATC code: J01CA04.

Mechanism of action

Moxypen Forte is a semisynthetic penicillin (beta-lactam antibiotic) that inhibits one or more enzymes (often referred to as penicillin-binding proteins, PBPs) in the biosynthetic pathway of bacterial peptidoglycan, which is an integral structural component of the bacterial cell wall. Inhibition of peptidoglycan synthesis leads to weakening of the cell wall, which is usually followed by cell lysis and death.

Moxypen Forte is susceptible to degradation by beta-lactamases produced by resistant bacteria and therefore the spectrum of activity of Moxypen Forte alone does not include organisms which produce these enzymes.

Pharmacokinetic/pharmacodynamic relationship

The time above the minimum inhibitory concentration (T>MIC) is considered to be the major determinant of efficacy for Moxypen Forte.

Mechanisms of resistance

The main mechanisms of resistance to Moxypen Forte are:

— Inactivation by bacterial beta-lactamases.

— Alteration of PBPs, which reduce the affinity of the antibacterial agent for the target.

Impermeability of bacteria or efflux pump mechanisms may cause or contribute to bacterial resistance, particularly in Gram-negative bacteria.

Breakpoints

MIC breakpoints for Moxypen Forte are those of the European Committee on Antimicrobial Susceptibility Testing (EUCAST) version 5.0.

The prevalence of resistance may vary geographically and with time for selected species, and local information on resistance is desirable, particularly when treating severe infections. As necessary, expert advice should be sought when the local prevalence of resistance is such that the utility of the agent in at least some types of infections is questionable.

Absorption

Moxypen Forte fully dissociates in aqueous solution at physiological pH. It is rapidly and well absorbed by the oral route of administration. Following oral administration, Moxypen Forte is approximately 70% bioavailable. The time to peak plasma concentration (T_max) is approximately one hour.

The pharmacokinetic results for a study, in which an Moxypen Forte dose of 250 mg three times daily was administered in the fasting state to groups of healthy volunteers are presented below.

In the range of 250 to 3000 mg the bioavailability is linear in proportion to dose (measured as C_max and AUC). The absorption in not influenced by simultaneous food intake.

Haemodialysis can be used for elimination of Moxypen Forte.

Distribution

About 18% of total plasma Moxypen Forte is bound to protein and the apparent volume of distribution is around 0.3 to 0.4 l/kg.

Following intravenous administration, Moxypen Forte has been found in gall bladder, abdominal tissue, skin, fat, muscle tissues, synovial and peritoneal fluids, bile and pus. Moxypen Forte does not adequately distribute into the cerebrospinal fluid.

From animal studies there is no evidence for significant tissue retention of drug-derived material. Moxypen Forte, like most penicillins, can be detected in breast milk.

Moxypen Forte has been shown to cross the placental barrier.

Biotransformation

Moxypen Forte is partly excreted in the urine as the inactive penicilloic acid in quantities equivalent to up to 10 to 25% of the initial dose.

Elimination

The major route of elimination for Moxypen Forte is via the kidney.

Moxypen Forte has a mean elimination half-life of approximately one hour and a mean total clearance of approximately 25 l/hour in healthy subjects. Approximately 60 to 70% of the Moxypen Forte is excreted unchanged in urine during the first 6 hours after administration of a single 250 mg or 500 mg dose of Moxypen Forte. Various studies have found the urinary excretion to be 50-85% for Moxypen Forte over a 24 hour period

Concomitant use of probenecid delays Moxypen Forte excretion.

Age

The elimination half-life of Moxypen Forte is similar for children aged around 3 months to 2 years and older children and adults. For very young children (including preterm newborns) in the first week of life the interval of administration should not exceed twice daily administration due to immaturity of the renal pathway of elimination. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

Gender

Following oral administration of Moxypen Forte to healthy males and female subjects, gender has no significant impact on the pharmacokinetics of Moxypen Forte.

Renal impairment

The total serum clearance of Moxypen Forte decreases proportionately with decreasing renal function.

Hepatic impairment

Hepatically impaired patients should be dosed with caution and hepatic function monitored at regular intervals.
