Following the iv administration of [14C]DMP.lactate (2.5 mg/kg), plasma concentrations of DMP declined in a biexponential manner and were measurable to 48 hr. The terminal elimination half-life was 37.7 hr. The mean AUC0-infinity of DMP was 1.58 micrograms.hr/ml. The volume of distribution was 89 liters/kg and the body clearance was 27 ml/min/kg. The disposition of total radioactivity was similar to that of DMP. Approximately 14% of the dose was eliminated in urine as DMP or total radioactivity. Renal clearance was 10% of the body clearance. Following the po administration of [14C]DMP.lactate (14 mg/kg) the mean Cmax of total radioactivity and DMP was 0.20 and 0.17 micrograms/ml, respectively. The respective mean AUC0-T was 0.37 and 0.21 micrograms.hr/ml. The mean oral bioavailability based on DMP plasma concentrations was 2.4%. The mean Cmax of DMP following a 100 mg/kg po dose of DMP.lactate was 14 micrograms/ml and the AUC0-T was 1.87 micrograms.ml/hr; the bioavailability was 3.2%. Approximately 1% of the orally administered dose was eliminated in urine as DMP.
