ACTION
Isoniazid may be bacteriostatic or bactericidal in action, depending
on the concentration of the
drug attained at the site of infection and the susceptibility of the
infecting organism. The exact
mechanism of action of isoniazid has not been fully elucidated, but
several mechanisms including
interference with metabolism of bacterial proteins, nucleic acids,
carbohydrates, and lipids have
been proposed. One of the principal actions of the drug appears to be
inhibition of mycolic acid
synthesis in susceptible bacteria which results in loss of
acid-fastness and disruption of the
bacterial cell wall. Isoniazid is active against susceptible bacteria
only when they are undergoing
cell division. Susceptible bacteria may undergo 1 or 2 divisions
before multiplication is arrested.
SPECTRUM
Isoniazid is a highly specific agent and is active only against
organisms of the genus
Mycobacterium. Isoniazid is active _in vitro_ and _in vivo_ against M.
tuberculosis, M. bovis, and
some strains of M. kansasii. _In vitro_, the minimum inhibitory
concentration (MIC) for most
susceptible mycobacteria is 0.02-0.2 mcg/mL in Lowenstein-Jensen
media.
CLINICAL PHARMACOLOGY
ABSORPTION
Isoniazid is readily absorbed from the GI tract. When given with food,
the extent of absorption
and peak plasma concentrations of the drug may be reduced. Following
oral application of the
drug, peak plasma concentrations are attained within 1-2 hours. Plasma
concentrations of the
drug in rapid isoniazid inactivators are 20-50 % of those in slow
isoniazid inactivators.
