[12-13], [40], [42]

Author (year) Study type Objective Animal model (age) Antigen strain Drug name (dosage) Duration of treatment Results  
Parihar et al. (2014) In vivo To investigate M. TB infection in a statin-treated experimental mice model C57BL/6 mice (8-12 weeks) Low-dose aerosol-based M. TB H37Rv Simvastatin or rosuvastatin (20 mg/kg/every other day) Six weeks Statins decreased bacilli burden (up to 10-fold) in the infected mice organs along with reduced histopathology
Lobato et al. (2014) In vivo Evaluation of the ability of atorvastatin to potentiate RIF’s anti-bacterial effect BALB/c mice-Shepard’s model 1 × 10live M. leprae in 10 μL inoculated in each hind footpad Atorvastatin (80 mg/kg/day) alone or in combination with RIF (1mg/Kg/week) Five months Atorvastatin synergized RIF’s anti-bacterial effect where none of the treatment strategies increased muscle damage or induced hepatotoxicity
Dutta et al. (2016) In vivo To investigate whether the addition of simvastatin to the first-line regimen (INH/RIF/PZA) shortens the duration of curative TB treatment BALB/c mice (4-6 weeks) Aerosol-based M. TB CDC1551 (3.7 log10) RIF (10 mg/kg), INH (10 mg/Kg) and PZA (25 mg/kg), plus simvastatin (25 mg/kg) Eight weeks (five days/week) The combination therapy with simvastatin reinforced mycobacterial killing and reduced the relapse rates when mice were treated for 2.5 and 3.5 months
Dutta et al. (2019) In vivo To determine anti-TB activity of statins in mice Female C3HeB/FeJ mice (5-6 weeks) Aerosol-based M. TB H37Rv (∼102 CFU/mouse lung) Simvastatin (90 mg/kg), pravastatin (50, 90 mg/kg) or fluvastatin (15 mg/kg) with INH (10 mg/kg), RIF (10 mg/kg), PZA (150 mg/kg) and EMB (100 mg/kg) Eight weeks (five days/week) Statin adjunctive therapy in mice had significantly reduced lung bacillary burdens
