Pharmacodynamics and pharmacokinetics
Benzylpenicillin is a biosynthetic antibiotic and belongs to the group of penicillins . The bactericidal effectiveness of the drug is manifested due to its ability to inhibit the synthesis of bacterial cell .
The effect of the drug is detrimental to gram-positive microorganisms: staphylococci , causative agents of diphtheria and anthrax , streptococci ; gram-negative bacteria: pathogens of gonorrhea and meningococcal infection ; spore-forming anaerobic rods; as well as spirochetes and actinomycetes .
Strains of staphylococci that produce penicillinase are not sensitive to the effects of benzylpenicillin .
When the drug is administered intramuscularly, TCmax in plasma is observed after 20-30 minutes. Binding to plasma proteins occurs by 60%. The antibiotic has good penetration into tissues, biological fluids and organs of the human body, with the exception of cerebrospinal fluid , prostate gland and eye tissues, and passes through the BBB . Excretion is carried out in unchanged form by the kidneys. T1/2 fluctuates between 30-60 minutes, with kidney pathologies it can increase to 4-10 hours or even more.
