Mechanism of Action

Pyrazinamide has bactericidal action against M. tuberculosis in acid environment present in macrophages and inflammed tissue. Together with rifampicin provides greatest sterilising action with reduction in relapse rate. Reduces tubular secretion of uric acid. Absorption: Readily absorbed from the GI tract (oral); peak plasma concentrations after 2 hr. Distribution: Body fluids and tissues (wide), CSF, enters breast milk. Metabolism: Hepatic; hydrolysed to pyrazinoic acid (active) then hydroxylated to 5-hydroxypyrazinoic acid (major excretory product). Excretion: Via urine by glomerular filtration (70% as metabolites, 4-14% as unchanged); 9-10 hr (elimination half-life), removed by dialysis.
