Spectrum of susceptibility

Capreomycin is most commonly used to treat '' Mycobacterium tuberculosis'' infections. ''Mycobacterium tuberculosis'' growth has been found to be inhibited at a concentration of 2.5 μg/mL.https://www.toku-e.com/Assets/MIC/Capreomycin%20sulfate.pdf

Side effects

High incidence: hematuria, urine output or urinary frequency significantly increased or decreased, loss of appetite or extreme thirst (hypokalemia, renal toxicity). Less incidence: hearing loss, tinnitus, gait instability, dizziness, dyspnea, lethargy, extreme weakness (neuromuscular blockade, renal toxicity, hypokalemia), nausea or vomiting. Significant renal toxicity: blood creatinine increase, blood urea nitrogen increase, poor creatinine clearance, proteinuria (need routine blood monitoring of renal functions and urine analysis) during usage of this medication. Damaging to the 8th cranial nerve . There can be vestibular dysfunction, such as some minor hearing loss after using the medication for 2 to 4 months. A certain block effect of neuromuscular. Can cause allergic reactions: rash, drug fever, facial flushing or pale, asthma, palpitations, sense of suppression in the chest, abdominal pain, anaphylactic shock.

Interactions

Combined with an aminoglycoside, it can increase the possibility of ototoxicity, nephrotoxicity and neuromuscular blockage, result in some hearing loss or can continue to deafness. It could be a temporary symptom, but often be permanent. Neuromuscular blockade can lead to skeletal muscle weakness and respiratory depression or paralysis (apnea). Using anti-cholinesterase or calcium salts may release this block. Combined with amphotericin B, vancomycin, bacitracin, paromomycin, cyclosporine, kanamycin, cisplatin, bumetanide, etoric acid, furosemide: Would Increase the possibility of ototoxicity and nephrotoxicity. Combined with antihistamines, buclizine, cyclizine, meclizine, phenothiazines, thioketones, trimethamine, and capreomycin: can ameliorate the symptoms of tinnitus, dizziness or vertigo and other ototoxic symptoms. Combined with anti-neuromuscular block drugs: can antagonize the effect of the anti-neuromuscular block drugs on the skeletal muscle (so need to adjust the dose of the drugs for anti-muscle weakness. Combined with ethyl sulfide isoniazid: may increase the side effects. Combined with methoxyflurane or polymyxin injection: may increase renal toxicity or neuromuscular blockade effect. Combined with opioid: The effect of central respiratory inhibition may increase, lead to prolonged respiratory inhibition or respiratory paralysis (apnea).

History

Capreomycin, an antiphlogistic antibiotic which was produced in the United States in 1960, and be applied in clinic in 1968. In 1979, capreomycin was used in the area of antituberculosis by inhibiting the growth of mycobacterium tuberculosis.
