The objective of this study was to examine urinary excretion profiles of two major triazolam metabolites, alpha-hydroxytriazolam (alpha-OHTRZ) and 4-hydroxytriazolam (4-OHTRZ) in humans. Urine samples were collected from three healthy male volunteers who had been previously administered single 0.25- and...
