Dosage Forms

Excipient information presented when available (limited, particularly for generics); consult specific product labeling.

Tablet, Oral:

Halcion: 0.25 mg [scored]

Generic: 0.125 mg, 0.25 mg

Brand Names: U.S.

  • Halcion

Pharmacologic Category

  • Benzodiazepine

Pharmacology

Binds to stereospecific benzodiazepine receptors on the postsynaptic GABA neuron at several sites within the central nervous system, including the limbic system and reticular formation. Enhancement of the inhibitory effect of GABA on neuronal excitability results by increased neuronal membrane permeability to chloride ions. This shift in chloride ions results in hyperpolarization (a less excitable state) and stabilization. Benzodiazepine receptors and effects appear to be linked to the GABA-A receptors. Benzodiazepines do not bind to GABA-B receptors (Vinkers 2012).

Distribution

Vd: 0.6 to 1.7 L/kg (Pakes 1981)

Metabolism

Extensively hepatic; hydroxylation via CYP3A4 (initial step in metabolism) with subsequent glucuronide conjugation to 6 metabolites, including a short-acting active metabolite, alpha-hydroxytriazolam (Pakes, 1981)

Excretion

Urine (~80% as metabolites; small amounts as unchanged drug)

Onset of Action

Hypnotic: 15 to 30 minutes (Pakes 1981)

Time to Peak

Oral: Within 2 hours

Duration of Action

Hypnotic: 6 to 7 hours

Half-Life Elimination

1.5 to 5.5 hours

Protein Binding

89% (Pakes, 1981)

Special Populations: Elderly

Cmax and AUC are increased; clearance is decreased (Greenblatt 1991)

Use: Labeled Indications

Insomnia: Short-term (generally 7 to 10 days) treatment of insomnia.

Limitations of use: The US Department of Veterans Affairs/Department of Defense guidelines for the management of chronic insomnia disorder and obstructive sleep apnea suggest against use in chronic insomnia because the risks of chronic use outweigh the benefits (VA/DoD 2019).

Off Label Uses

Oral sedation prior to outpatient dental procedures

Data from a randomized, double-blind, placebo-controlled trial suggests the use of triazolam may be beneficial as oral sedation prior to outpatient dental procedures [Berthold 1997]. Clinical experience also suggests the utility of triazolam in this setting [Dionne 2006].

Contraindications

Dosing: Adult

Insomnia (short-term use): Usual dose: 0.25 mg at bedtime; 0.125 mg at bedtime may be sufficient in some patients, such as those with low body weight; maximum dose: 0.5 mg/day.

Dental preprocedure oral sedation (off-label use): 0.25 mg 1 hour before procedure; 0.125 mg used for elderly patients or patients sensitive to sedative effects (Dionne 2006).

Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.

Dosing: Geriatric

Elderly and/or debilitated patients: Insomnia (short-term use): Oral: Initial: 0.125 mg at bedtime; maximum dose: 0.25 mg/day.

Risks from concomitant use with opioids

Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation.

Warnings/Precautions

Concerns related to adverse effects:

• Amnesia: Benzodiazepines have been associated with anterograde amnesia (Nelson 1999). Traveler's amnesia (if taken to induce sleep while traveling) due to insufficient time for sleep prior to awakening and initiating activity has also been reported.

• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving).

• Hypersensitivity reactions: Reports of hypersensitivity reactions, including anaphylaxis and angioedema, have been reported with triazolam. Patients who develop angioedema should not be rechallenged with triazolam.

• Paradoxical reactions: Paradoxical reactions, including hyperactive or aggressive behavior, have been reported with benzodiazepines; risk may be increased in adolescent/pediatric patients, geriatric patients, or patients with a history of alcohol use disorder or psychiatric/personality disorders (Mancuso 2004).

• Sleep-related activities: Hazardous sleep-related activities such as sleep-driving, cooking and eating food, and making phone calls while asleep have been noted with benzodiazepines (Dolder 2008).

Disease-related concerns:

• Depression: Use caution in patients with depression, particularly if suicidal risk may be present. Minimize risks of overdose by prescribing the least amount of drug that is feasible in suicidal patients. Worsening of depressive symptoms has also been reported with use of benzodiazepines.

• Drug abuse: Use with caution in patients with a history of drug abuse or acute alcoholism; potential for drug dependency exists. Tolerance, psychological and physical dependence may occur with prolonged use.

• Hepatic impairment: Use with caution in patients with hepatic impairment; undergoes extensive hepatic metabolism.

• Renal impairment: Use with caution in patients with renal impairment.

• Respiratory disease: Use with caution in patients with respiratory compromise, COPD, or sleep apnea.

Concurrent drug therapy issues:

• Concomitant use with opioids: [US Boxed warning]: Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation.

Special populations:

• Debilitated patients: Use with caution in debilitated patients; potential for oversedation, impaired coordination, and dizziness with use.

• Elderly: Elderly patients experience greater sedation and increased psychomotor impairment (Greenblatt 1991). Elderly patients may be at an increased risk of death with use; risk has been found highest within the first 4 months of use in elderly dementia patients (Jennum 2015; Saarelainen 2018).

• Fall risk: Use with extreme caution in patients who are at risk of falls; benzodiazepines have been associated with falls and traumatic injury (Nelson 1999).

Other warnings/precautions:

• Appropriate use: Does not have analgesic, antidepressant, or antipsychotic properties. Should be used only after evaluation of potential causes of sleep disturbance. Failure of sleep disturbance to resolve after 7 to 10 days may indicate psychiatric or medical illness. Use for >21 days requires complete reevaluation of patient. A worsening of insomnia or the emergence of new abnormalities of thought or behavior may represent unrecognized psychiatric or medical illness and requires immediate and careful evaluation. Prescription should be written for a maximum of 7 to 10 days and should not be prescribed in quantities exceeding a 1-month supply. Use lowest effective dose; adverse reactions of triazolam are dose related.

• Tolerance: Triazolam is a short half-life benzodiazepine. Duration of action after a single dose is determined by redistribution rather than metabolism. Tolerance develops to the hypnotic effects (Vinkers 2012). Chronic use of this agent may increase the perioperative benzodiazepine dose needed to achieve desired effect.

• Withdrawal: A longer sleep-onset latency and increased awakenings during sleep may occur for 1 to 2 days following the discontinuation of GABA-mediated (GABAergic) medications. A more severe withdrawal syndrome may rarely occur following abrupt discontinuation or large decreases in dose after sustained use (>10 days), and is characterized by new-onset agitation, ataxia, depersonalization, dizziness, dysphoria, fatigue, headache, hypersensitivity to stimuli, irritability, muscle cramps or pain, nausea, sweating, twitching, vomiting, and weakness. This withdrawal syndrome generally resolves within weeks or upon re-initiation of the GABAergic medication. Intermittent dosing may reduce the risk of withdrawal symptoms (BAP [Wilson 2019]). Use caution when reducing dose or withdrawing therapy; decrease slowly and monitor for withdrawal symptoms.

Monitoring Parameters

Respiratory rate.

Pregnancy Considerations

A case report describes placental transfer of triazolam following a maternal overdose (Sakai 1996).

Teratogenic effects have been observed with some benzodiazepines; however, additional studies are needed. The incidence of premature birth and low birth weights may be increased following maternal use of benzodiazepines; hypoglycemia and respiratory problems in the neonate may occur following exposure late in pregnancy. Neonatal withdrawal symptoms may occur within days to weeks after birth and “floppy infant syndrome” (which also includes withdrawal symptoms) have been reported with some benzodiazepines (Bergman 1992; Iqbal 2002; Wikner 2007). Infants exposed to triazolam during pregnancy should be monitored for respiratory depression, sedation, withdrawal, or feeding problems.

Data collection to monitor pregnancy and infant outcomes following exposure to triazolam is ongoing. Health care providers are encouraged to enroll females exposed to triazolam during pregnancy in the National Pregnancy Registry for Other Psychiatric Medications (866-961-2388 or https://womensmentalhealth.org/research/pregnancyregistry/othermedications/).
