Abstract It had been shown that 3 to 5 hr exposures to ambient concentrations of ozone (O3) increase pentobarbital-induced sleeping time in female mice, hamsters, and rats without decreasing heptatic cytochrome P-450 levels or selected mixed function oxidases. To elucidate potential mechanisms involved, clearance of pentobarbital from the blood of O3-exposed mice was examined. Pentobarbital clearance followed first-order kinetics with a one-compartment model. Mice exposed to 1960 micrograms per cu. m. (1ppm) for 5 hr had a 71% increase in the plasma half-life of pentobarbital. It therefore appears possible that pentobarbital-induced sleeping time is increased due to a decrease in hepatic metabolism of pentobarbital.
