MIC: 5-15 μg/mL (mycobacterium)

In Vitro Methdilazine (0-20 μg/mL approximately, 18 h) inhibits kinds of mycobacterium with MIC values ranging from 5 μg/mL to 15 μg/mL[1]. Cell Proliferation Assay[1] Cell Line: mycobacterium: M. smegmatis 798/1546, M.,fortuitum 1529, M. scrofulaceum 1323, M. gordonae 1324, M. rnarinum 50, M.,flavescens 1541, M. terrae 1450, M. tuberculosis, H37Ra 16, H37Rv 16, K1, K2, ICRC bacillus,'Skinsnes' bacillus. Concentration: 0-20 μg/mL approximately Incubation Time: 18 h Result: Inhibited mycobacterium with MIC values ranging from 5 μg/mL to 15 μg/mL.
In Vivo Methdilazine (Intraperitoneal injection, 10 μg/gm body wt/day, 6 weeks) is antagonistic to mycobacteria in H37Rv infected mice[1]. Methdilazine (Oral administration, 10 mg/kg per day, 28 days) improves survival of Mycobacterium Tuberculosis (Mtb) H37Rv infected mice[2]. Animal Model: H37Rv infected mice[1] Dosage: 10 μg/gm body wt/day, 6 weeks Administration: Intraperitoneal injection Result: Displayed an anti-mycobacterial activity to mycobacteria. Animal Model: Mycobacterium Tuberculosis (Mtb) H37Rv infected Swiss albino male mice[2] Dosage: 10 mg/kg per day for 28 days Administration: Oral administration Result: Increased surviving time to 28 days with no sign of disease, showed 71.42% survival.
