Effects of anesthetics on diphenylhydantoin metabolism in the rat: possible inhibition by diethyl ether.


The effects of diethyl ether and urethane on the elimination of diphenylhydantoin (DPH) in the rat were compared. The apparent half-life of DPH following a dose of 10 mg/kg, iv, under continuous ether anesthesia was 284 +/- 47 min, while the half-life under urethane anesthesia was 25.5 +/- 6.3 min. The latter was in agreement with the literature value for… (More)
