Ethambutol interferes with RNA synthesis, causing suppression of Mycobacteria multiplication. It also has bacteriostatic action against M tuberculosis by acting on rapidly growing pathogens in cavity walls and is also effective in slow-growing pathogens. Has some action against atypical opportunistic Mycobacteria e.g. M kansasii, M avium complex (MAC). Absorption: 80% is absorbed from the GI tract (oral). Distribution: Lungs, kidneys, erythrocytes, CSF (in meningitis); crosses the placenta and enters breast milk.
