Description:
Studies were conducted to investigate the effect of ozone in prolonging pentobarbital (PEN)-induced sleeping time (S.T.). Since ozone is a common air pollutant, an ozone-induced alteration of mechanisms of drug action could have public health implications. It was shown that a 5-hr exposure to 1960 micrograms ozone/cu. m. (1 ppm) caused an increased PEN-induced S.T. in female mice (three strains), rats, and hamsters. This response was not observed in male rats or in male mice even when the latter were exposed for 5 hr/day for 3 days. Male hamsters were affected, but less so than females. These data are interpreted as a systemic effect of ozone on mechanisms of the termination of action of pentobarbital.
