    PHARMACOLOGY

    Pharmacotherapeutic Group: Antibiotic, antiprotozoal agent

    Pharmacodynamic properties: Metronidazole exerts antimicrobial effects in an anaerobic environment. The 5 nitro group undergoes reductive transformation to an active intermediate which then exerts an inhibitory effect against DNA. The reduced metabolite also causes a loss of the helical structure of DNA with subsequent DNA strand breakage.

    Pharmacokinetic properties:

    Absorption:Readily absorbed from the GI tract (oral), absorption delayed by the food. Time to peak plasma concentration:1-2 hr (oral). Bioavailability: 80%

    Distribution: Widely distributed in most body tissues and fluids. Crosses the placenta and enters breast milk. Plasma protein binding: <20%

    Metabolism: Undergoes hepatic metabolism by side chain oxidation and glucoronide formation.

    Excretion: Via urine (as metabolites) and faeces (small amounts). Elimiantion half-life: 8 hr

     INDICATIONS
