Triazolam

Triazolam is indicated for the short-term treatment of insomnia (generally 7 to 10 days) in adults. Triazolam is a benzodiazepine indicated for the short-term treatment of insomnia (generally 7 to 10 days) in adults.

• Tablets: 0.125 mg white, imprinted with "G3717"
• Tablets: 0.25 mg powder blue, scored, imprinted with "G3718"
• Tablets: 0.125 mg ( 3 )
• Scored tablets: 0.25 mg ( 3 )

Triazolam is contraindicated in:

• Patients with known hypersensitivity to triazolam, any of component of triazolam, 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) ].
• Known hypersensitivity to triazolam or other benzodiazepines ( 4 )
• Concomitant use with medications that significantly impair the oxidative metabolism mediated by cytochrome P450 3A (CYP 3A) including ketoconazole, itraconazole, nefazodone, and several human immunodeficiency virus (HIV) protease inhibitors ( 4 , 5.8 , 17 )

• Persistent or Worsening Insomnia : Since sleep disturbances may be the presenting manifestation of a physical and/or psychiatric disorder, symptomatic treatment of insomnia should be initiated only after a careful evaluation of the patient. The failure of insomnia to remit after 7 to 10 days of treatment may indicate the presence of a primary psychiatric and/or medical illness that should be evaluated. ( 5.4 )
• "Sleep-driving" and Other Complex Behaviors : Complex behaviors such as "sleep-driving" have been reported. The use of alcohol and other central nervous system (CNS) depressants with sedative-hypnotics appears to increase the risk, as well as doses exceeding the maximum recommended dose. ( 5.5 )
• CNS Manifestations : An increase in daytime anxiety, abnormal thinking, and behavioral changes have been reported. Emergence of any new behavioral changes require careful and immediate evaluation. ( 5.6 )
• Effects on Driving and Operating Heavy Machinery : Patients receiving triazolam should be cautioned against driving or operating heavy machinery, as well as avoiding concomitant use with alcohol and other CNS depressant drugs. ( 5.7 )
• Patients with Depression : Caution should be exercised in patients with signs or symptoms of depression that could be intensified by hypnotic drugs. Prescribe the least number of tablets feasible to avoid intentional overdose. ( 5.9 )
• Neonatal Sedation and Withdrawal Syndrome : Triazolam use during pregnancy can result in neonatal sedation and/or neonatal withdrawal. ( 5.10 , 8.1 )

5.1 Risks From Concomitant Use With Opioids Concomitant use of benzodiazepines, including triazolam, and opioids may result in profound sedation, respiratory depression, coma, and death. Because of these risks, reserve concomitant prescribing of these drugs in patients for whom alternative treatment options are inadequate. Observational studies have demonstrated that concomitant use of opioid analgesics and benzodiazepines increases the risk of drug-related mortality compared to use of opioids alone. If a decision is made to prescribe triazolam concomitantly with opioids, prescribe the lowest effective dosages and minimum durations of concomitant use, and follow patients closely for signs and symptoms of respiratory depression and sedation. In patients already receiving an opioid analgesic, prescribe a lower initial dose of triazolam than indicated in the absence of an opioid and titrate based on clinical response. If an opioid is initiated in a patient already taking triazolam, prescribe a lower initial dose of the opioid and titrate based upon clinical response. Advise both patients and caregivers about the risks of respiratory depression and sedation when triazolam is used with opioids. Advise patients not to drive or operate heavy machinery until the effects of concomitant use with the opioid have been determined [see Drug Interactions (7.1) ] .

5.2 Abuse, Misuse, and Addiction The use of benzodiazepines, including triazolam, exposes users to the risks of abuse, misuse, and addiction, which can lead to overdose or death. Abuse and misuse of benzodiazepines often (but not always) involve the use of doses greater than the maximum recommended dosage and commonly involve concomitant use of other medications, alcohol, and/or illicit substances, which is associated with an increased frequency of serious adverse outcomes, including respiratory depression, overdose, or death [see Drug Abuse and Dependence (9.2) ] . Before prescribing triazolam and throughout treatment, assess each patient's risk for abuse, misuse, and addiction (e.g., using a standardized screening tool). Use of triazolam, particularly in patients at elevated risk, necessitates counseling about the risks and proper use of triazolam along with monitoring for signs and symptoms of abuse, misuse, and addiction. Prescribe the lowest effective dosage; avoid or minimize concomitant use of CNS depressants and other substances associated with abuse, misuse, and addiction (e.g., opioid analgesics, stimulants); and advise patients on the proper disposal of unused drug. If a substance use disorder is suspected, evaluate the patient and institute (or refer them for) early treatment, as appropriate.

5.3 Dependence and Withdrawal Reactions To reduce the risk of withdrawal reactions, use a gradual taper to discontinue triazolam or reduce the dosage (a patient-specific plan should be used to taper the dose) [see Dosage and Administration (2.3) ] . Patients at an increased risk of withdrawal adverse reactions after benzodiazepine discontinuation or rapid dosage reduction include those who take higher dosages, and those who have had longer durations of use. Acute Withdrawal Reactions The continued use of benzodiazepines, including triazolam, may lead to clinically significant physical dependence. Abrupt discontinuation or rapid dosage reduction of triazolam after continued use, or administration of flumazenil (a benzodiazepine antagonist) may precipitate acute withdrawal reactions, which can be life-threatening (e.g., seizures) [see Drug Abuse and Dependence (9.3) ] . Protracted Withdrawal Syndrome In some cases, benzodiazepine users have developed a protracted withdrawal syndrome with withdrawal symptoms lasting weeks to more than 12 months [see Drug Abuse and Dependence (9.3) ] .

5.4 Persistent or Worsening Insomnia Since sleep disturbances may be the presenting manifestation of a physical and/or psychiatric disorder, symptomatic treatment of insomnia should be initiated only after a careful evaluation of the patient. The failure of insomnia to remit after 7 to 10 days of treatment may indicate the presence of a primary psychiatric and/or medical illness that should be evaluated. Worsening of insomnia or the emergence of new thinking or behavior abnormalities may be the consequence of an unrecognized psychiatric or physical disorder. Such findings have emerged during the course of treatment with sedative-hypnotic drugs. 5.5 "Sleep-driving" and Other Complex Behaviors Complex behaviors such as "sleep-driving" (i.e., driving while not fully awake after ingestion of a sedative-hypnotic, with amnesia for the event) have been reported with triazolam use. These events can occur in sedative-hypnotic-naïve as well as in sedative-hypnotic-experienced persons. Although behaviors such as sleep-driving may occur with sedative-hypnotics alone at recommended dosages, the use of alcohol and other central nervous system (CNS) depressants with sedative-hypnotics appears to increase the risk of such behaviors, as does the use of sedative-hypnotics at doses exceeding the maximum recommended dose. Due to the risk to the patient and the community, discontinuation of sedative-hypnotics should be strongly considered for patients who report a "sleep-driving" episode. Other complex behaviors (e.g., preparing and eating food, making phone calls, or having sex) have been reported in patients who are not fully awake after taking a sedative-hypnotic, including triazolam. As with sleep-driving, patients usually do not remember these events.

5.6 Central Nervous System Manifestations An increase in daytime anxiety has been reported for triazolam after as few as 10 days of continuous use. In some patients this may be a manifestation of interdose withdrawal. If increased daytime anxiety is observed during treatment, discontinuation of treatment may be advisable. A variety of abnormal thinking and behavior changes have been reported to occur in association with the use of benzodiazepine hypnotics including triazolam. Some of these changes may be characterized by decreased inhibition, e.g., aggressiveness and extroversion that seem excessive, similar to that seen with alcohol and other CNS depressants (e.g., sedative/hypnotics). Other kinds of behavioral changes have also been reported, for example, bizarre behavior, agitation, hallucinations, depersonalization. […]

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The incidences cited below are estimates of clinical reactions among 1003 subjects who participated in the short term (duration of 1 to 42 days) placebo-controlled clinical trials of triazolam. Adverse reactions leading to discontinuation in two multi-dose placebo controlled clinical trials include coordination disorders, drowsiness, grogginess, somnolence, depression, restlessness, dizziness, lightheadedness, headache, nausea, visual disturbance, nervousness, abdominal distress, bladder trouble, aching limbs, backache, and blepharitis.

• Use with Opioids : Increase the risk of respiratory depression ( 7.1 )
• Use with Other CNS Depressants : Produces additive CNS depressant effects ( 7.1 )
• Use with CYP 3A4 Inhibitors : Increased risk of adverse reactions ( 4 , 5.8 , 7.1 )

7.1 Drugs Having Clinically Important Interactions With Triazolam Table 2 includes clinically significant drug interactions with triazolam [see Clinical Pharmacology (12.3) ] . Table 2: Clinically Important Drug Interactions with Triazolam Opioids Clinical implication The concomitant use of benzodiazepines and opioids increases the risk of respiratory depression because of actions at different receptor sites in the CNS that control respiration. Benzodiazepines interact at GABA A sites and opioids interact primarily at mu receptors. When benzodiazepines and opioids are combined, the potential for benzodiazepines to significantly worsen opioid-related respiratory depression exists. Prevention or management Limit dosage and duration of concomitant use of triazolam and opioids, and monitor patients closely for respiratory depression and sedation [see Warnings and Precautions (5.1) ] . CNS Depressants Clinical implication Triazolam produces additive CNS depressant effects when co-administered with other CNS depressants. Prevention or management Limit dosage and duration of triazolam during concomitant use with CNS depressants. Strong Inhibitors of CYP 3A Clinical implication Concomitant use of triazolam with strong CYP3A inhibitors has a profound effect on the clearance of triazolam, resulting in increased concentrations of triazolam and increased risk of adverse reactions [see Clinical Pharmacology (12.3) ]. Prevention or management Do not administer triazolam with a strong CYP3A4 inhibitor [see Contraindications (4) , Warnings and Precautions (5.8) ]. Moderate and Weak Inhibitors of CYP 3A Clinical implication Concomitant use of triazolam with moderate or weak inhibitors of CYP3A inhibitors may increase the concentrations of triazolam, resulting in increased risk of adverse reactions [see Clinical Pharmacology (12.3) ]. Prevention or management Use with caution and consider appropriate dose reduction of triazolam when coadministered with moderate and weak CYP3A inhibitors [see Warnings and Precautions (5.8) ]. Strong Inducers of CYP 3A Clinical implication Coadministration of triazolam with strong inducers of CYP3A4 can significantly decrease the plasma concentration of triazolam and may decrease effectiveness of triazolam. Prevention or management Caution is recommended during coadministration of triazolam with strong inducers of CYP3A4. Interactions Based on Experience with Other Benzodiazepines or in vitro Studies with Triazolam Clinical implication Available data from clinical studies of benzodiazepines other than triazolam, from in vitro studies with triazolam, or from in vitro studies with benzodiazepines other than triazolam suggest a possible drug interaction with triazolam [see Clinical Pharmacology (12.3) ]. Prevention or management Caution is recommended during coadministration of triazolam with any of these drugs. [see Warnings and Precautions (5.8) ].

Lactation : A lactating woman may pump and discard breast milk during treatment and for 28 hours after triazolam administration. ( 8.2 )

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to psychiatric medications, including triazolam, during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Psychiatric Medications at 1-866-961-2388 or visiting online at https://womensmentalhealth.org/pregnancyregistry/ . Risk Summary Neonates born to mothers using benzodiazepines late in pregnancy have been reported to experience symptoms of sedation and/or neonatal withdrawal [see Warnings and Precautions (5.10) and Clinical Considerations ] . Available data from published observational studies of pregnant women exposed to benzodiazepines do not report a clear association with benzodiazepines and major birth defects ( see Data ). The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Benzodiazepines cross the placenta and may produce respiratory depression, hypotonia, and sedation in neonates. Monitor neonates exposed to triazolam during pregnancy or labor for signs of sedation, respiratory depression, hypotonia, and feeding problems. Monitor neonates exposed to triazolam during pregnancy for signs of withdrawal. Manage these neonates accordingly [see Warnings and Precautions (5.10) ]. Data Human Data Published data from observational studies on the use of benzodiazepines during pregnancy do not report a clear association with benzodiazepines and major birth defects. Although early studies reported an increased risk of congenital malformations with diazepam and chlordiazepoxide, there was no consistent pattern noted. In addition, the majority of more recent case-control and cohort studies of benzodiazepine use during pregnancy, which were adjusted for confounding exposures to alcohol, tobacco and other medications, have not confirmed these findings. Animal Data Oral administration of triazolam to pregnant rats and rabbits during the period of organogenesis caused skeletal developmental changes (variations and malformations) at maternally toxic doses in rats and at doses in rats and rabbits which are approximately equal to or greater than 200 times the maximum recommended human dose (MRHD) of 0.5 mg/day based on mg/m 2 body surface area. Oral administration of triazolam to male and female rats before mating, and continuing during gestation and lactation did not result in embryotoxicity at doses up to approximately 100 times the MRHD based on mg/m 2 body surface area, but did cause an increase in the number of stillbirths and postnatal pup mortalities at doses greater than or equal to approximately 40 times the MRHD based mg/m 2 body surface area. 14 C-triazolam was administered orally to pregnant mice. Drug-related material appeared uniformly distributed in the fetus with 14 C concentrations approximately the same as in the brain of the mother.

8.2 Lactation Risk Summary There are reports of sedation, poor feeding and poor weight gain in infants exposed to benzodiazepines through breast milk. There are no data on the presence of triazolam in human milk or the effects on milk production. Triazolam and its metabolites are present in the milk of lactating rats ( see Data ). When a drug is present in animal milk, it is likely that the drug will be present in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for triazolam and any potential adverse effects on the breastfed infant from triazolam or from the underlying maternal condition. Clinical Considerations Infants exposed to triazolam through breast milk should be monitored for sedation, poor feeding and poor weight gain. A lactating woman may consider interrupting breastfeeding and pumping and discarding breast milk during treatment and for 28 hours (approximately 5 elimination half-lives) after triazolam administration in order to minimize drug exposure to a breast fed infant. Data Both triazolam and triazolam metabolites were detected in milk of rats. Lactating rats were orally administered 0.3 mg/kg 14 C-triazolam; drug and metabolite levels were determined in milk collected at 6 and 24 hours after administration.

8.4 Pediatric Use Safety and effectiveness of triazolam have not been established in pediatric patients.

8.5 Geriatric Use Elderly patients exhibit higher plasma triazolam concentrations due to reduced clearance as compared with younger subjects at the same dose. Because elderly patients are especially susceptible to dose related adverse reactions and to minimize oversedation, the smallest effective dose should be used [see Dosage and Administration (2.2) , Clinical Pharmacology (12.3) ] .

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 (GABA A ) receptors in the brain and enhances GABA-mediated synaptic inhibition.
