Streptomycin is an antibiotic that belongs to the aminoglycoside class. It was first discovered in 1943 and is primarily used to treat infections caused by certain bacteria, particularly Mycobacterium tuberculosis, the bacterium responsible for tuberculosis. Streptomycin works by inhibiting bacterial protein synthesis, effectively stopping the growth of the bacteria. This medication is usually administered through injection and can be used in combination with other antibiotics for more effective treatment. While it is effective, Streptomycin can have side effects, including potential damage to the kidneys and hearing loss, so monitoring during treatment is essential.
