... The disposition of [2-(14)C]-2-methylimidazole (2-MI) has been investigated following po administration of either 5, 50, or 150 mg/kg to male F344 rats. Excretion data indicated that absorption of 2-MI was both rapid and proportional to dose in the range studied. Approximately 90% of the total dose was eliminated in urine within 24 hr. Most of the remaining 14C was excreted in feces and as expired 14CO2. Excretion data were similar following iv administration of 5 mg/kg. Little or no enterohepatic circulation of compound occurred, since biliary excretion of 2-MI-derived 14C was negligible. Approximately 70% of the 14C excreted in urine, following all dosing, consisted of parent compound. High-performance liquid chromatography (HPLC) chromatograms for all treatment groups were similar, indicating that metabolism of 2-MI in rats was not affected by dose or route of administration.

The toxicokinetics of 2-methylimidazole (2-MI) were studied in male and female Fischer 344 rats after a single iv dose of 10 mg/kg or gavage dose of 25, 50, or 100 mg/kg. The 2-MI was formulated in 0.05 M phosphate-buffered saline (pH 7.4). The iv profiles could be best described by a two-compartment model with first-order elimination. The terminal elimination half-life, volume of distribution at steady state, and clearance values were 0.78 and 0.85/hr, 1.5 and 1.9 L, and 4.97 and 12.0 L/hr/kg for males and females, respectively. After a gavage dose, the plasma concentration time profiles could be best described by a one-compartment model, no lag phase, and first-order absorption and elimination. The peak 2-MI plasma concentrations increased proportionately with dose and were reached within 35 to 50 min (T(max)) for all groups. The estimated half-life value for 2-MI was about 1 hr for the iv group and the male 25-, 50-, or 100-mg/kg groups and female 25-mg/kg groups. Clearance increased for the male 100- and female 50- and 100- mg/kg groups. For a given dose group, clearance was also two to three times greater for female rats when compared to male rats. Absolute bioavailability for 2-MI was estimated to approach 97%. The results of this study indicated that 2-MI was (1) rapidly and completely absorbed, (2) quickly eliminated, (3) cleared differently for females than for males, (4) affected somewhat by dose for females, and (5) unlikely to undergo tissue accumulation following repeated exposure.
