Pharmacotherapeutic group Antimicrobial drugs for systemic use. Antibacterial drugs for systemic use. Second generation cephalosporins ATC code J01DC02

Pharmacological properties Pharmacokinetics Cefuroxime axetil is rapidly absorbed from the gastrointestinal tract and hydrolyzed by nonspecific esterases of the intestinal mucosa and blood to cefuroxime. Plasma protein binding is 50%. Cefuroxime is distributed in tissues and body fluids. When taking the drug after meals, the maximum plasma concentration for dosages of 125 mg, 250 mg and 500 mg is 2.1 mcg/ml, 4.1 mcg/ml, 7 mcg/ml, respectively. The maximum concentration is reached 3 hours after taking the drug. Therapeutic concentrations in the cerebrospinal fluid are achieved only with meningitis. Penetrates through the placenta and is excreted in breast milk. It is excreted unchanged in the urine. The half-life is approximately 1.2 hours. Pharmacodynamics Cefuroxime is a second-generation, broad-spectrum cephalosporin antibiotic. It has a bactericidal effect by inhibiting the synthesis of bacterial cell walls. Cefuroxime acetylates membrane-bound transpeptidases, thereby disrupting the peptido-glycan cross-linking necessary to ensure cell wall strength and rigidity. Cefuroxime is resistant to the action of many bacterial beta-lactamases, as a result of which it is active against most types of microorganisms resistant to penicillin and amoxicillin. Cefuroxime is active against the following microorganisms: Gram-negative bacteria: Escherichia coli, Haemophilus influenzae (including species that produce beta-lactamases), Haemophilus parainfluenzae, Klebsiellapneumoniae, Moraxella catarrhalis (including species that produce beta-lactamases), Neisseria gonorrhoeae (including species that produce beta -lactamases), Salmonella spp., Shigella spp., Proteus mirabilis, Enterobacter spp. Gram-positive bacteria: Staphylococcus aureus (including beta-lactamase producing species), Streptococcus pneumoniae, Streptococcus pyogenes. Certain species of enterococci, such as Enterococcus faecalis, are resistant to cefuroxime. Anaerobes: Peptococcus spp., Peptostreptococcus spp., Clostridium spp., Bacteroides spp., Fusobacterium spp.

Indications for use - acute bronchitis, exacerbation of chronic bronchitis, pneumonia - otitis, sinusitis, tonsillitis, pharyngitis - pyelonephritis, cystitis, urethritis - abdominal infections - gynecological infections - infections of bones and joints - infections of the skin and soft tissues.

Method of administration and dosage The recommended dose for adults and children over 12 years of age is 250 mg 2 times a day. For more severe infections or infections caused by less sensitive microorganisms, 500 mg 2 times a day is recommended. For uncomplicated urinary tract infections, the recommended dose is 250 mg once a day. If necessary, in some patients with urinary tract infections, the dosage can be increased to 250 mg 2 times a day. The maximum daily dose for adults is 6 g. Typically, the duration of treatment is 7 days (from 5 to 10 days). The course of treatment should be extended to 10 days in patients with infections caused by beta-hemolytic streptococcus to avoid the occurrence of acute rheumatic fever or acute glomerulonephritis. For patients with impaired renal function, the dosage regimen is set taking into account creatinine clearance values. For better absorption, the drug should be taken after meals. The tablets should be swallowed whole without chewing, so children under 12 years of age can use the drug in injection form.

Side effects Common (?1/100, <1/10) eosinophilia headache nausea, diarrhea short-term increase in the level of liver enzymes (ALT, AST, LDH) Uncommon (?1/1000, <1/100) vomiting eczema positive Coombs test result , thrombocytopenia, leukopenia (sometimes severe) Rarely (?1/10000, <1/1000) pseudomembranous colitis urticaria, itching Very rarely (<1/10000) hemolytic anemia drug fever, serum sickness, anaphylaxis, erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis jaundice (mainly cholestatic), hepatitis

Contraindications - hypersensitivity to cephalosporin antibiotics, penicillins, carbapinems - children under 12 years of age - first trimester of pregnancy

Drug interactions Megasef is not active in the gastrointestinal tract, has minimal impact on intestinal flora and vitamin K synthesis. When taken simultaneously, it enhances the anticoagulant effect of warfarin. When used simultaneously with loop diuretics, the risk of nephrotoxicity increases. Probenecid competes with Megasef for renal tubular secretion, which leads to increased plasma concentrations of cefuroxime. To determine plasma glucose levels in patients taking Megasef, it is recommended to use glucose oxidase or hexokinase methods. Megasef does not affect serum and urine creatinine levels.

Special instructions: Use with caution in case of severe renal dysfunction, or if there is a history of colitis. In patients with hypersensitivity to penicillins, allergic reactions to cephalosporin antibiotics are possible. If a severe allergic reaction to Megasef occurs, it is necessary to discontinue the drug and prescribe appropriate treatment; in especially severe cases, there may be a need for resuscitation measures. Long-term use of the drug, like other broad-spectrum antibiotics, can lead to increased proliferation of microorganisms insensitive to the drug (for example, Candida, Enterococci, Clostridium difficile), and therefore it may be necessary to discontinue the drug. When using broad-spectrum antibiotics, the development of pseudomembranous colitis is possible; this must be kept in mind when patients experience diarrhea during or after antibacterial therapy. During treatment, a positive direct Coombs reaction and a false positive urine reaction to glucose are possible.

Pregnancy and lactation period Use in the second and third trimesters of pregnancy, as well as during lactation, is possible in cases where the expected benefit of therapy for the mother outweighs the potential risk to the fetus. Features of the effect of the drug on the ability to drive a vehicle or potentially dangerous mechanisms. Not installed.

Newborns are prescribed 30-100 mg/kg per day in 2-3 administrations. Pneumonia . For pneumonia, it is recommended to administer the drug 1.5 g or 2 times a day (intramuscularly or intravenously) for 48-72 hours. In the future, it is possible to use the tablet form of MEGASEF® Gonorrhea. For gonorrhea, the drug is prescribed in a dose of 1.5 g once in the form of 1 injection or in the form of 2 injections of 750 mg. Meningitis. For meningitis, adults are prescribed 3 g intravenously 3 times a day. Children over 3 months are prescribed intravenously 150-250 mg/kg per day in 3-4 injections. Newborns are prescribed the drug intravenously at a dose of 100 mg/kg per day. To prevent infectious complications during abdominal, pelvic and orthopedic operations, the drug is administered intravenously in a dose of 1.5 g simultaneously with induction of anesthesia. If necessary, additional injections of the drug intramuscularly at a dose of 750 mg are possible after 8 and 16 hours. For operations on the heart, lungs, esophagus and blood vessels, 1.5 g of the drug is administered intravenously with induction of anesthesia, then 750 mg is administered 3 times a day over the next 24 -48 hours. Renal failure. If renal function is impaired, a reduced dose should be used. The dosage should be determined by the degree of renal impairment and the sensitivity of the microorganism. Dosage of MEGACEF® for injection in adults with impaired renal function: Creatinine clearance (ml/min) Dose (mg) Frequency > 20,750 – 1500 Every 8 hours 10 – 20,750 Every 12 hours Patients with renal failure on continuous hemodialysis using arterial -venous shunt or high-flow hemofiltration in intensive care units, MEGASEF®. prescribed in a dose of 750 g 2 times a day. For patients undergoing low-rate hemofiltration, doses recommended for renal impairment are prescribed. Rules for preparing solutions for parenteral administration For intramuscular or intravenous injections, add water for injection (according to the table), shake gently until a suspension is formed. For IM administration: Dose Amount of water for injection 750 mg 3 ml For IV administration: Dose Amount of water for injection 750 mg 6 ml Jet IV administration - slowly over 3-5 minutes. For continuous intravenous infusion, MEGASEF® solution can be added to the following infusion solutions: sodium chloride solution 0.9%, dextrose solution 5% and 10%.

Side effects: - thrombophlebitis (with intravenous administration), pain at the injection site (with intramuscular administration) - nausea, vomiting, diarrhea - transient increase in the activity of liver transaminases, cholestatic jaundice, hepatitis, pseudomembranous colitis - skin rash, itching, eosinophilia, Quincke's edema , erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, fever, anaphylaxis - leukopenia, neutropenia, thrombocytopenia, hemolytic anemia, hypoprothrombinemia (with long-term use in high doses) - interstitial nephritis, candidiasis - hearing impairment Contraindications: - hypersensitivity to cefuroxime and other cephalosporins - pregnancy and lactation - bleeding and diseases of the gastrointestinal tract Drug interactions: It is recommended to use the glucose oxidase or hexokinase method when determining plasma glucose levels in patients receiving cefuroxime. False-positive reactions for the presence of glucose in urine may occur in tests with copper reduction (Benedict, Fehling, Clinitest). Enzyme tests should be used to determine glycosuria. However, it does not cause false-positive results like some other cephalosporins. A positive direct Coombs reaction is also possible. Cefuroxime, by suppressing the intestinal flora, prevents the synthesis of vitamin K. Therefore, when used simultaneously with drugs that reduce platelet aggregation (non-steroidal anti-inflammatory drugs, salicylates, sulfinpyrazone), the risk of bleeding increases. For the same reason, when used simultaneously with anticoagulants, an increase in the anticoagulant effect is observed. When used simultaneously with loop diuretics, the risk of nephrotoxicity increases. Coadministration of probenecid with cefuroxime slows tubular secretion, increases peak serum concentrations by approximately 40%, and increases the half-life by approximately 30%. Special instructions: In patients with hypersensitivity to penicillins, allergic reactions to cephalosporin antibiotics are possible; In such patients, cephalosporins should be prescribed with caution. Large doses of cephalosporins should be prescribed with caution in cases of severe renal impairment, as well as in patients receiving concomitant treatment with strong diuretics such as furosemide and aminoglycosides. Patients with diseases of the gastrointestinal tract (especially colitis) should use with caution. If an allergic reaction occurs, you must stop taking the drug.
