Kanamycin (Injection)

Kanamycin, known in the marketplace as Kantrex, is injected into patients who have bacterial infections in order to kill the bacteria and stop the growth of new infections.


Kanamycin is considered to be an aminoglycoside antibiotic type of medication. It kills bacteria and fights infections as well as preventing new growth. Kanamycin is typically used for a short period of time, an average of seven days but no more than 10 days total. Kanamycin does not treat viral infections, but is an effective treatment for severe infections such as tuberculosis. It is also effective on E.coli infections, as well as different species of bacteria.

Kanamycin works by forming a bond with a portion of the bacteria that is in control of using proteins to further the growth of the organism. By binding with this part of the bacteria, Kanamycin stops it from synthesizing these proteins and cutting off a major supply useful to its growth. By cutting off the growth of the bacteria, it soon dies without producing more and the infection is healed by the body.

Kanamycin, an aminoglycoside antibiotic type of medication, is injected by doctors into patients who have been diagnosed with bacterial infections such as tuberculosis. This medication effectively binds to a cellular structure in the bacteria, preventing it from growing and eventually causing it to die. When the bacterium is eradicated from the body, it can begin to heal from the damage it has caused.

Patients typically experience an improvement in their symptoms within 24 to 48 hours and should seek alternate treatment if they do not see any signs of improvement after 3 to 5 days. Patients are injected into a vein or muscle and will receive a dosage amount calculated on their body mass.
