Triazolam is a hypnotic with a short mean plasma half-life reported to be in the range of 1.5 to 5.5
hours. In normal subjects treated for seven days with four times the recommended dosage, there was
no evidence of altered systemic bioavailability, rate of elimination, or accumulation. Peak plasma levels
are reached within 2 hours following oral administration. Following recommended doses of triazolam,
triazolam peak plasma levels in the range of 1 to 6 ng/mL are seen. The plasma levels
achieved are proportional to the dose given.
Triazolam and its metabolites, principally as conjugated glucuronides which are presumably inactive,
are excreted primarily in the urine. Only small amounts of unmetabolized triazolam appear in the
urine. The two primary metabolites accounted for 79.9% of urinary excretion. Urinary excretion appeared
to be biphasic in its time course.
.....In sleep laboratory studies, triazolam significantly decreased sleep latency, increased the duration of
sleep and decreased the number of nocturnal awakenings. After two weeks of consecutive nightly
administration, the drug’s effect on total wake time is decreased, and the values recorded in the last
third of the night approach baseline levels. On the first and/or second night after drug discontinuance
(first or second post-drug night), total time asleep, percentage of time spent sleeping, and rapidity of
falling asleep frequently were significantly less than on baseline (predrug) nights. This effect is often called “rebound” insomnia.
