Pancef, 100 mg/5 ml 32 g

Pantsef is a broad-spectrum antibacterial (bactericidal).

Pharmacodynamics

Cefixime is an oral cephalosporin antibiotic of III generation with pronounced antibacterial activity against most Gram-positive and Gram-negative microorganisms.

The mechanism of action is caused by inhibition of the synthesis of the cell membrane of the pathogen. It is resistant to beta-lactamases of both Gram-positive and Gram-negative microorganisms.

Highly active against Streptococcus pneumoniae, Streptococcus pyogenes, Streptococcus agalactiae, Haemophilus influenzae, Haemophilus parainfluenzae, Moraxella catarrhalis (including strains producing beta-lactamases). beta-lactamase-producing strains), Escherichia coli, Proteus mirabilis, Proteus vulgaris, Neisseria gonorrhoeae, Klebsiella pneumoniae, Klebsiella oxytoca, Pasteurella multocida, Providencia spp, Salmonella spp., Shigella spp., Citrobacter spp. (including Citrobacter diversus), Serratia marcescens.

Pseudomonas spp., Acinetobacter spp., some strains of Streptococcus, Enterococcus spp. (methicillin-resistant strains), Listeria monocytogenes, Bacteroides fragilis, most strains of Staphylococcus, Enterobacter and Clostridium are resistant to cefixime.

Pharmacokinetics

Absorption. After oral administration, cefixime absorption is 40-50% regardless of ingestion; however, serum C_max has been noted to be reached faster by 0.8 h when the drug is taken with food. When the drug is taken in tablet form at a dose of 400 mg, C_max in plasma is 3.5 µg/ml. T_max is 2-6 hours.

After taking the suspension, C_max (compared to tablets) is 25-50% higher. T_max is 2-6 h for 400 mg/5 ml suspension and 2-5 h for 200 mg/5 ml suspension. T_max in plasma is also 2-6 h.

Distribution. Binding to plasma proteins is 50-60%. V_d is 0.6-1.1 l/kg. High concentrations of the drug remain in serum, bile, urine for a long time.

Metabolism. There are no data on cefixime metabolites.

Elimation. Cefixime is excreted mainly by the kidneys by glomerular filtration in unchanged form – 50%, with bile – 10%.

T_1/2 in healthy volunteers averages 3-4 h, in some cases up to 9 h. Long T_1/2 makes single dosing possible.

In impaired renal function, in creatinine Cl 20-40 ml/min T_1/2 increases and averages 6.4 h, in creatinine Cl 5-20 ml/min T_1/2 is 11.5 h.

Indications

Infectious and inflammatory diseases caused by microorganisms sensitive to cefixime:

upper respiratory tract infections (tonsillitis, pharyngitis, sinusitis);
otitis media;
lower respiratory tract infections (bronchitis, tracheobronchitis);
urinary tract infections;
uncomplicated gonorrhea (urethra and cervix).

Pharmacological effect

Pancef is a broad-spectrum antibacterial (bactericidal).

Pharmacodynamics

Cefixime is a third-generation cephalosporin antibiotic for oral administration with pronounced antibacterial activity against most gram-positive and gram-negative microorganisms.

The mechanism of action is due to inhibition of the synthesis of the pathogen’s cell membrane. Resistant to beta-lactamases of both gram-positive and gram-negative microorganisms.

Highly active against Streptococcus pneumoniae, Streptococcus pyogenes, Streptococcus agalactiae, Haemophilus influenzae, Haemophilus parainfluenzae, Moraxella catarrhalis (including strains producing beta-lactamases), Escherichia coli, Proteus mirabilis, Proteus vulgaris, Neisseria gonorrhoeae, Klebsiella pneumoniae, Klebsiella oxytoca, Pasteurella multocida, Providencia spp., Salmonella spp., Shigella spp., Citrobacter spp. (including Citrobacter diversus), Serratia marcescens.

Pseudomonas spp., Acinetobacter spp., some strains of Streptococcus, Enterococcus spp. (methicillin-resistant strains), Listeria monocytogenes, Bacteroides fragilis, most strains of Staphylococcus, Enterobacter and Clostridium are resistant to cefixime.

Pharmacokinetics

Suction. After oral administration, the absorption of cefixime is 40–50%, regardless of food intake; however, it was noted that Cmax in the blood serum is achieved faster by 0.8 hours when taking the drug with food. When taking the drug in tablet form at a dose of 400 mg, Cmax in plasma is 3.5 mcg/ml. Tmax – 2–6 hours.

After taking the suspension, Cmax (compared to tablets) is 25–50% higher. Tmax – 2–6 hours for a suspension of 400 mg/5 ml and 2–5 hours for a suspension of 200 mg/5 ml. Tmax in blood plasma is also 2–6 hours.

Distribution. Plasma protein binding is 50–60%. Vd is 0.6–1.1 l/kg. High concentrations of the drug remain for a long time in blood serum, bile, and urine.

Metabolism. There is no data on the metabolites of cefixime.

Excretion. Cefixime is excreted mainly by the kidneys by glomerular filtration in unchanged form – 50%, with bile – 10%.

T1/2 in healthy volunteers averages 3–4 hours, in some cases up to 9 hours. Long T1/2 makes single dosing possible.

If renal function is impaired, with a creatinine Cl of 20–40 ml/min, T1/2 increases and averages 6.4 hours; with a creatinine Cl of 5–20 ml/min, T1/2 is 11.5 hours.

Special instructions

Patients with a history of allergic reactions to penicillins may have increased sensitivity to cephalosporin antibiotics. If an allergic reaction occurs, you must stop using the drug and, if necessary, take appropriate measures.

As with the use of other antibacterial drugs, long-term use of cefixime may disrupt the normal intestinal microflora, which can lead to the growth of Clostridium difficile, causing severe diarrhea and pseudomembranous colitis.

During treatment, a false-positive direct Coombs reaction and a false-positive urine reaction to glucose and ketonuria are possible.

Active ingredient

With caution: old age, renal failure, colitis (history).

Side Effects

Allergic reactions: urticaria, skin flushing, skin itching, itching in the genital area, eosinophilia, fever, exudative erythema multiforme (including Stevens-Johnson syndrome), toxic epidermal necrolysis (Lyell’s syndrome).

From the nervous system: headache, dizziness, tinnitus.

From the hematopoietic organs: pancytopenia, leukopenia, neutropenia, agranulocytosis, thrombocytopenia, aplastic anemia, hemolytic anemia, bleeding.

Laboratory indicators: increased activity of liver transaminases and alkaline phosphatase, hyperbilirubinemia, increased urea nitrogen, hypercreatininemia, increased PT.

Other: candidiasis, development of hypovitaminosis B, shortness of breath.

Interaction

Blockers of tubular secretion (allopurinol, diuretics, etc.) delay the excretion of cefixime by the kidneys, which can lead to increased toxicity.

Cefixime reduces the prothrombin index and enhances the effect of indirect anticoagulants.

Antacids containing magnesium or aluminum hydroxide slow down the absorption of the drug. With the simultaneous use of cefixime and carbamazepine, the concentration of the latter increases.

Overdose

Symptoms: increased manifestations of the described side effects.

Treatment: gastric lavage, symptomatic and supportive therapy.

Hemodialysis and peritoneal dialysis are ineffective.
