The active substances of the drug are procaine benzylpenicillin and benzathine benzylpenicillin, which belong to the beta-lactam antibiotics, penicillin group, and dihydrostreptomycin sulfate, which belongs to the antibacterial bactericidal agents of the aminoglycoside group.
Procaine benzylpenicillin shows bactericidal effect mainly on Gram-positive bacteria. The action of the substance is based on inhibition of the activity of enzymes of peptidoglycan synthesis, which leads to cessation of bacterial growth, and also activates enzymes that hydrolyze peptidoglycan, which weakens the covalent bonds of the cell wall. Bacterial cells stop dividing, enlarge, swell and disintegrate with the formation of small particles. The peculiarities of benzylpenicillin procaine are slow absorption and prolonged action when administered.
Benzathine benzylpenicillin is a beta-lactam antibiotic of the type G prolonged-acting penicillin group. It acts bactericidally on sensitive microorganisms by inhibiting synthesis of cell wall mucopeptides. It is active against Gram-positive microorganisms: Staphylococcus spp. (penicillinase-unforming, Streptococcus spp, including Streptococcus pneumoniae and Streptococcus pyogenes A, Corynebacterium diphtheriae, Erysipelothrix rhusiopathiae, anaerobic spore-forming bacilli: Bacillus anthracis, Clostridium spp., Actinomyces israelli; gram-negative microorganisms: Neisseria gonorrhoeae, Neisseria meningitidis, Treponema spp.
Penicillins are highly active against Gram-positive microorganisms (Staphylococcus spp., Streptococcus spp., Corynebacterium diphtheriae and others). The mechanism of action is based on disruption of synthesis of mucopeptide peptidoglycan, which leads to inhibition of synthesis of the cell wall of the microorganism, suppression of growth and reproduction of bacteria.
Dihydrostreptomycin is an aminoglycoside antibiotic that acts bactericidally on Gram-negative and Gram-positive microorganisms (Pasteurella spp., Salmonella spp., E.coli, Klebsiella spp., Hemophilus spp., Brucella spp., Shigella spp., Mycobacterium spp.). The antibacterial effect is based on the binding of the streptomycin molecule to the ribosomal 30 S subunit of the microbial cell, which leads to the formation of inferior proteins, stopping the growth and development of the bacteria. Unlike benzylpenicillin procaine, dihydrostreptomycin sulfate acts on microorganisms in both the reproduction and quiescent stages.
After intramuscular administration, penicillins and dihydrostreptomycin are widely distributed throughout all body tissues. High concentrations are detected in the kidneys, liver, muscles and lungs.
When parenteral administration, penicillin is absorbed slowly, so its peak serum concentration is observed after 3-4 hours.
Dihydrostreptomycin is well absorbed from the injection site. It penetrates well into milk.
The peak concentration of dihydrostreptomycin is seen after 30-90 minutes, and it persists in the body at therapeutic concentration for at least 24 hours. Penicillin and dihydrostreptomycin are eliminated from the body mainly with the urine.
