It has a wide spectrum of action, which includes various aerobic and anaerobic gram-positive and gram-negative microorganisms, including Pseudomonas aeruginosa. Resistant to beta-lactamases of both gram-positive and gram-negative microorganisms. It is highly active against Streptococcus pneumoniae, Streptococcus pyogenes, Streptococcus agalactiae, Haemophilus influenzae, Haemophilus parainfluenzae, Moraxella catarrhalis (including strains producing beta-lactamases), Escherichia coli, Proteusella gibelis bacteria, oxytoca, Pasteurella multocida, Providencia spp., Salmonella spp., Shigella spp., Citrobacter spp. (including Citrobacter diversus), Serratia marcescens.

Pharmacokinetics
When administered, bioavailability is 40-50%. Food increases the maximum absorption time by 0.8 hours. TCmax - 2-6 hours for tablets and suspension 400 mg / 5 ml and 2-5 hours for suspension 200 mg / 5 ml. Cmax after oral administration of 100, 200 and 400 mg - 1-1.3, 2-3 and 3.5-4.4 μg / ml, respectively. After taking the suspension, Cmax is 25-50% higher (due to the difference in bioavailability, it is not recommended to replace the suspension with tablets Bexacim treatment of otitis media). Cmax in the urine after administration in doses of information, 200 and 400 mg - 73, 107 and 164 μg / ml, respectively. High concentrations of the drug Bexacim for a long time in blood serum, bile, and urine. T1 / 2 - 3-4 hours, with renal failure - 6.4-11.5 hours. Distribution volume - 0.11 l / kg. Communication with plasma proteins - 65-70%. It is excreted by the kidneys unchanged - 50%, with bile - 10%.

With uncomplicated gonorrhea of the urethra and cervix - 400 mg once.
In case of impaired renal function, the dose is set depending on the level of QC in serum: with QC of 21-60 ml / min or in patients on hemodialysis, the daily dose should be reduced by 25%; with CC of 20 ml / min or less, or in patients undergoing peritoneal dialysis, the daily dose should be reduced by 2 times. Method of suspension: turn the bottle over and shake the powder. Add 40 ml of chilled boiled water in 2 stages and shake until a homogeneous suspension is formed.

special instructions
Patients with a history of allergic reactions to penicillins may be hypersensitive to cephalosporin antibiotics. During treatment, a false positive direct Coombs reaction and a false positive urine reaction to ketonuria, glucose are possible.
In some diseases, antibiotics cannot be avoided. But only those drugs that are active against the microorganisms that caused it can cope with the disease.
