Boxed Warning
• Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs 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 [see Warnings and Precautions (5.1), Drug Interactions (7.1)]. • The use of benzodiazepines, including triazolam, exposes users to risks of abuse, misuse, and addiction, which can lead to overdose or death. Abuse and misuse of benzodiazepines commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with an increased frequency of serious adverse outcomes. Before prescribing triazolam and throughout treatment, assess each patient’s risk for abuse, misuse, and addiction [see Warnings and Precautions (5.2)]. • The continued use of benzodiazepines, including triazolam, may lead to clinically significant physical dependence. The risks of dependence and withdrawal increase with longer treatment duration and higher daily dose. Abrupt discontinuation or rapid dosage reduction of triazolam after continued use may precipitate acute withdrawal reactions, which can be life-threatening. To reduce the risk of withdrawal reactions, use a gradual taper to discontinue triazolam or reduce the dosage [see Dosage and Administration (2.3), Warnings and Precautions (5.3)].
Indications and Usage
Triazolam is indicated for the short-term treatment of insomnia (generally 7 to 10 days) in adults.
Contraindications
Triazolam is contraindicated in: •Patients with known hypersensitivity to triazolam, any of component of triazolam tablets, or other benzodiazepines. Reactions consistent with angioedema (involving the tongue, glottis, or larynx), dyspnea, and throat closing have been reported and may be fatal. •Concomitant administration of strong cytochrome P450 (CYP 3A) enzyme inhibitors (e.g., ketoconazole, itraconazole, nefazodone, lopinavir, ritonavir) [see Warnings and Precautions (5.8), Drug Interactions (7.1)].
Adverse Reactions
The following serious adverse reactions are discussed in greater detail in other sections: •Risks from Concomitant Use with Opioids [see Warnings and Precautions (5.1)] •Abuse, Misuse, and Addiction [see Warnings and Precautions (5.2)] •Dependence and Withdrawal Reactions [see Warnings and Precautions (5.3)] •Persistent or Worsening Insomnia [see Warnings and Precautions (5.4)] •“Sleep-driving” and Other Complex Behaviors [see Warnings and Precautions (5.5)] •Central Nervous System Manifestations [see Warnings and Precautions (5.6)] •Effects on Driving and Operating Heavy Machinery [see Warnings and Precautions (5.7)] •Patients with Depression [see Warnings and Precautions (5.9)] •Neonatal Sedation and Withdrawal Syndrome [see Warnings and Precautions (5.10)] •Compromised Respiratory Function [see Warnings and Precautions (5.11)]
Mechanism of Action
Triazolam is a benzodiazepine. Triazolam exerts its effect for the short-term treatment of insomnia through binding to the benzodiazepine site of the gamma-aminobutyric acid-A (GABAA) receptors in the brain and enhances GABA-mediated synaptic inhibition.
Overdosage
Overdosage of benzodiazepines is characterized by central nervous system depression ranging from drowsiness to coma. In mild to moderate cases, symptoms can include drowsiness, confusion, dysarthria, lethargy, hypnotic state, diminished reflexes, ataxia, and hypotonia. Rarely, paradoxical or disinhibitory reactions (including agitation, irritability, impulsivity, violent behavior, confusion, restlessness, excitement, and talkativeness) may occur. In severe overdosage cases, patients may develop respiratory depression and coma. Overdosage of benzodiazepines in combination with other CNS depressants (including alcohol and opioids) may be fatal [see Warnings and Precautions (5.2)]. Markedly abnormal (lowered or elevated) blood pressure, heart rate, or respiratory rate raise the concern that additional drugs and/or alcohol are involved in the overdosage. In managing benzodiazepine overdosage, employ general supportive measures, including intravenous fluids and airway management. Flumazenil, a specific benzodiazepine receptor antagonist indicated for the complete or partial reversal of the sedative effects of benzodiazepines in the management of benzodiazepine overdosage, can lead to withdrawal and adverse reactions, including seizures, particularly in the context of mixed overdosage with drugs that increase seizure risk (e.g., tricyclic and tetracyclic antidepressants) and in patients with long-term benzodiazepine use and physical dependency. The risk of withdrawal seizures with flumazenil use may be increased in patients with epilepsy. Flumazenil is contraindicated in patients who have received a benzodiazepine for control of a potentially life-threatening condition (e.g., status epilepticus). If the decision is made to use flumazenil, it should be used as an adjunct to, not as a substitute for, supportive management of benzodiazepine overdosage.
