Abstrakt: The disposition and metabolism of a 5-nitroimidazole compound (SC 28538) was investigated in the rat, beagle dog and rhesus monkey. The absorption of [14C]-SC 28538 was rapid and essentially complete after oral dosage in male animals, and also after intravaginal dosage in the female rat. Peak plasma levels of radioactivity occurred within 2 h of dosage. In the rat and dog the radioactivity was excreted predominantly in the faeces (greater than 60%) but in the monkey more than 60% was excreted in the urine. In both the male and pregnant female rat radioactivity was concentrated in the gastro-intestinal tract, liver and harderian gland and the concentrations of radioactivity in other tissues was generally lower than in plasma. Radioactivity was cleared more rapidly from plasma than from the majority of tissues. SC 28538 was extensively metabolised to form glucuronide and amino acid conjugates. The half-life of SC 28538 was of the order of 1 h in the dog and 3.7 h in the monkey.
