体内研究:
Capreomycin (1.4, 7.2, and 14.5 mg/kg for inhale; 20 mg/kg for i.m.; 4 weeks) decreases the wet lung weight and lowers bacterial burden in the lungs of infected guinea pigs.Animal Model:Male guinea pigs?[836 ± 162.3 g; infected via the respiratory route with nebulized suspensions 2 × 105 CFU/mL of Mycobacterium tuberculosis (strain H37Rv)]
Dosage:1.4, 7.2, and 14.5 mg/kg for inhale; 20 mg/kg for i.m.
Administration:Inhaling or i.m.; 4 weeks
Result:Significantly decreased the wet lung weight at 14.5 mg/kg, and smaller than receiving 1.4 mg/kg group and controls.Significantly lowered bacterial burden in the lungs (3.52 ± 0.20 CFU/mL; P < 0.05) at 14.5 mg/kg than controls (4.58 ± 0.20 CFU/mL) and at 1.4 and 7.2 mg/kg (4.02 ± 0.32 and 4.01 ± 0.29 CFU/mL, respectively).
