... Triazolam /is/ indicated for the short-term treatment of insomnia characterized by difficulty in falling asleep, frequent nocturnal awakenings, and/or early morning awakenings. ... Failure of insomnia to remit after 7 to 10 days of treatment may indicate the presence of a primary psychiatric or medical illness. Worsening of insomnia or the emergence of new abnormalities of thinking or behavior may be the consequence of an unrecognized psychiatric or physical disorder. /Included in US product labeling/

In patients who have received prolonged triazolam therapy, abrupt discontinuance of the drug should be avoided since manifestations of withdrawal can be precipitated. While the risk and severity of withdrawal manifestations are increased as the duration and dose increase, such manifestations are increased as the duration and dose increase, such manifestations can occur at usual doses given for relatively short periods (e.g., 1-2 weeks) and occasionally between nightly doses. Therefore, if the drug is to be discontinued in any patient receiving more than the lowest dose for longer than a few weeks, it si recommended that dosage be tapered gradually. Gradual tapering is particularly important in patients with a seizure history. There also is evidence that abrupt discontinuance of triazolam after relatively short periods of therapy (e.g., 1 week) can result in rebound insomnia, which generally persists for one to two nights. Therefore, some clinicians suggest that gradual dosage reduction (e.g., over several nights) also be considered when discontinuing short-term triazolam therapy, since the development of rebound insomnia can perpetuate continued use of hypnotics in patients with insomnia.

For the short-term treatment of insomnia.
A short-acting benzodiazepine used as a hypnotic agent in the treatment of insomnia. Some countries temporarily withdrew triazolam from the market because of concerns about adverse reactions, mostly psychological, associated with higher dose ranges. Its use at lower doses with appropriate care and labeling has been reaffirmed by the FDA and most other countries. Triazolam has a shorter half-life than chlordiazepoxide, flurazepam, and prazepam and does not generate active metabolites.
Anti-Anxiety Agents
Agents that alleviate ANXIETY, tension, and ANXIETY DISORDERS, promote sedation, and have a calming effect without affecting clarity of consciousness or neurologic conditions. ADRENERGIC BETA-ANTAGONISTS are commonly used in the symptomatic treatment of anxiety but are not included here. (See all compounds classified as Anti-Anxiety Agents.)
GABA Modulators
Substances that do not act as agonists or antagonists but do affect the GAMMA-AMINOBUTYRIC ACID receptor-ionophore complex. GABA-A receptors (RECEPTORS, GABA-A) appear to have at least three allosteric sites at which modulators act: a site at which BENZODIAZEPINES act by increasing the opening frequency of GAMMA-AMINOBUTYRIC ACID-activated chloride channels; a site at which BARBITURATES act to prolong the duration of channel opening; and a site at which some steroids may act. GENERAL ANESTHETICS probably act at least partly by potentiating GABAergic responses, but they are not included here. (See all compounds classified as GABA Modulators.)
Adjuvants, Anesthesia
Agents that are administered in association with anesthetics to increase effectiveness, improve delivery, or decrease required dosage. (See all compounds classified as Adjuvants, Anesthesia.)

Absorption
Bioavailability is 44% (oral) and 53% (sublingual).
Route of Elimination
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.
Plasma half-life, elimination coefficient, concentration, and apparent volume of distribution were calculated at steady state and mean values were 53 hr, 0.0147/hr, 884 ng/mL, & 1.13 l/kg /respectively/.

Triazolam is rapidly and nearly completely absorbed from the GI tract. It has a biphasic half-life with a reported mean apparent half-life of 3.4 hr for the initial phase and 7.8 hr for the terminal phase. It is reported to be extensively bound to plasma proteins. It is excreted in the urine in the form of its metabolites with only small amounts appearing unchanged.

Benzodiazepines bind nonspecifically to bezodiazepine receptors BNZ1, which mediates sleep, and BNZ2, which affects affects muscle relaxation, anticonvulsant activity, motor coordination, and memory. As benzodiazepine receptors are thought to be coupled to gamma-aminobutyric acid-A (GABAA) receptors, this enhances the effects of GABA by increasing GABA affinity for the GABA receptor. Binding of GABA to the site opens the chloride channel, resulting in a hyperpolarized cell membrane that prevents further excitation of the cell.
In animals, benzodiazepines protect against seizures induced by electrical stimulation and by pentylenetetrazol; benzodiazepines appear to act, at least partly, by augmenting presynaptic inhibition. The drugs suppress the spread of seizure activity but do not abolish the abnormal discharge from a focus in experimental models of epilepsy. In usual doses, benzodiazepines appear to have very little effect on the autonomic nervous system, respiration, or the cardiovascular system. /Benzodiazepines/

... /Benzodiazepines/ appear to act at the limbic, thalamic, and hypothalamic levels of the CNS, producing anxiolytic, sedative, hypnotic, skeletal muscle relaxant, and anticonvulsant effects. The effects of benzodiazepines may be mediated through the inhibitory neurotransmitter gamma-aminobutyric acid. Benzodiazepines are capable of producing all levels of CNS depression from mild sedation to hypnosis to coma. /Benzodiazepines/

Anxiolytic and possibly paradoxical CNS stimulatory effects of benzodiazepines are postulated to result from release of previously suppressed responses (disinhibition). After usual doses of benzodiazepines for several days, the drugs cause a moderate decrease in rapid eye movement (REM) sleep. REM rebound does not occur when the drugs are withdrawn. Stage 3 and 4 sleep are markedly reduced by usual doses of the drugs; the clinical importance of these sleep stage alterations has not been established. /Benzodiazepines/

Benzodiazepines appear to produce skeletal muscle relaxation predominantly by inhibiting spinal polysynaptic afferent pathways, but the drugs may also inhibit monosynaptic afferent pathways. The drugs may inhibit monosynaptic and polysynaptic reflexes by acting as inhibitory neuronal transmitters or by blocking exitatory synaptic transmission. The drugs may also directly depress motor nerve and muscle function. /Benzodiazepines/
