Plasma levels of metyrapone were measured in rats standardized in an alternating 12-hr-light and 12-hr-dark regimen, every 4 hr over a 24-hr period. The results indicate a circadian periodicity with a half-life at 22.00 hr (10 p.m.) which was approximately 2.5-fold longer than that observed at 10.00 hr (10 a.m.).
