Streptomycin has a wide spectrum of action, affecting not only gram-positive, but also gram-negative microorganisms. It suppresses the activity of Mycobacterium tuberculosis, pathogens of tularemia, brucellosis.
The mechanism of the antimicrobial action of streptomycin, like other aminoglycosides, is based on the inhibition of protein synthesis by ribosomes in a microbial cell. Streptomycin is poorly absorbed from the gastrointestinal tract and poorly penetrates through the mucous membranes, therefore, when administered in the form of an aerosol, it suppresses the infection only locally, in the lumen of the bronchi and alveoli. To obtain a resorptive effect, streptomycin is administered intramuscularly. In this case, it is well reabsorbed, active plasma concentrations last up to 24 hours, so the drug can be prescribed 1-2 times a day. In plasma, about 30% of streptomycin is protein bound.
The drug is evenly and quickly distributed in the body. With repeated injections, sufficiently high concentrations of the drug are created in the pleural fluid, but it penetrates poorly through the blood-brain barrier.

Streptomycin and other aminoglycosides can cause severe complications: balance and hearing impairment (ototoxic effect), which in 8% of cases can lead to deafness.
The simultaneous appointment of streptomycin and other aminoglycosides is unacceptable due to a sharp increase in the toxic effect. Streptomycin crosses the placenta, so its introduction at the end of pregnancy can disrupt the development of the organ of hearing and lead to the birth of a deaf child.
Nephrotoxicity is manifested by a negative damaging effect on the renal tubules. The frequency of kidney damage in the treatment of aminoglycosides reaches 17%. The drugs are administered intramuscularly and into body cavities (pleural, abdominal, etc.).
