Capreomycin is an injectable broad spectrum antibiotic used in the therapy of drug resistant tuberculosis as a second line agent, always in combination with other antituberculosis drugs. Capreomycin has not been linked to cases of clinically apparent liver disease.


Capreomycin (kap" ree oh mye' sin) is a cyclic peptide antibiotic that was initially isolated from the bacterium, Streptomyces capreolus. Capreomycin is believed to act by binding to bacterial ribosomes and inhibiting protein synthesis. Capreomycin is similar to viomycin and is considered bacterostatic rather than bacterocidal. While structurally different, capreomycin has similar antibacterial activity and side effects to the aminoglycosides (streptomycin, kanamycin, amikacin). Capreomycin is currently used only as a secondary agent in the treatment of active tuberculosis, always in combination with other antituberculosis agents such as isoniazid, ethambutol, pyrazinamide and/or rifampin (but not streptomycin or the aminoglycosides) and usually for multidrug resistant mycobacterial infections. Capreomycin was approved for use in the United States in 1973, but is currently rarely used, streptomycin or a modern aminoglycoside being used in its place. Capreomycin is available in vials for intramuscular or intravenous injection under the trade name of Capastat. The typical dose is 15 mg/kg/day (maximum of 1 gram per day) intramuscularly for 2 to 4 months and it is always given in combination with other antituberculosis agents. The dose must be modified based upon renal function. Side effects resemble those of the aminoglycosides and include tinnitus, hearing loss, proteinuria and renal dysfunction, and local injection reactions.

Guidelines and detailed discussion of therapy of tuberculosis is available at the Centers for Disease Control and Prevention website:


Intramuscular therapy with capreomycin has not been definitely linked to liver injury, either in the form of asymptomatic elevations in serum enzymes or of clinically apparent liver injury. However, the agent is rarely used and is always used in combination with other antituberculosis medications, many of which are well known to cause liver injury. Nevertheless, in the few studies done, capreomycin has not been associated with an increase in the rate of serum enzyme elevations or in episodes of acute liver injury above or beyond what was reported in the comparator arm.

Likelihood score: E (unlikely cause of clinically apparent liver injury).

Mechanism of Injury

Capreomycin is excreted largely unchanged in the urine. Its lack of hepatic metabolism and known renal toxicity (which is dose-limiting) may account for its lack of hepatotoxicity. The majority of toxicities of capreomycin resemble those of streptomycin and the aminoglycosides and include oto- and nephrotoxicity.

[First line medications used in the therapy of tuberculosis in the US include ethambutol, isoniazid, pyrazinamide, rifabutin, rifampin, and rifapentine. Second line medications include streptomycin, capreomycin, cycloserine, ethionamide, fluoroquinolones such as levofloxacin and moxifloxacin, aminoglycosides such as amikacin, and para-aminosalicylic acid (PAS).]
