Ethambutol
Ethambutol is a bacteriostatic agent indicated alongside medications such as [isoniazid], [rifampin], and [pyrazinamide] in the treatment of pulmonary tuberculosis. Ethambutol was first described in the literature in 1961. It was developed out of a need for therapies active against isoniazid resistant strains of Mycobacterium tuberculosis.  Ethambutol was granted FDA approval on 6 November 1967.
