FDA Extends Expiration Dates for Certain Meridian Autoinjectors: Updated July 2017

The FDA is alerting health care providers and emergency responders that certain lots of AtroPen (atropine), CANA (diazepam), morphine sulfate, and pralidoxime chloride autoinjectors manufactured by Meridian Medical Technologies can be used beyond the labeled expiration date, which should help mitigate potential shortages of these drugs. To ensure patient safety, products should be stored under the manufacturer’s labeled storage conditions.

ALERT: US Boxed Warning
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 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.

Abuse, misuse, and addiction:

The use of benzodiazepines, including diazepam, 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 diazepam and throughout treatment, assess each patient's risk for abuse, misuse, and addiction.

Dependence and withdrawal reactions:

Oral: The continued use of benzodiazepines, including diazepam, 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 diazepam 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 diazepam or reduce the dosage.

Injection, nasal spray, rectal gel: The continued use of benzodiazepines, including diazepam, may lead to clinically significant physical dependence. The risks of dependence and withdrawal increase with longer treatment duration and higher daily dose. Although diazepam is indicated only for intermittent use, if used more frequently than recommended, abrupt discontinuation or rapid dosage reduction may precipitate acute withdrawal reactions, which can be life-threatening. For patients using diazepam more frequently than recommended, to reduce the risk of withdrawal reactions, use a gradual taper to discontinue diazepam.

Dosing: Hepatic Impairment: Pediatric

There are no dosage adjustments provided in the manufacturer's labeling; use with caution. The oral tablets are contraindicated in severe hepatic impairment.

Dosing: Adult

(For additional information see "Diazepam: Drug information")

Dosage guidance:

Safety: Reduce dose or avoid use in patients receiving opioids or with significant chronic disease (eg, respiratory compromise). Avoid use in patients with a history of substance use, misuse of medications, or depression, except for acute or emergency situations (eg, status epilepticus) (Ref).

Anxiety

Anxiety:

Anxiety, acute/severe (monotherapy or adjunctive therapy):

IM, IV, Oral: 2 to 10 mg every 3 to 6 hours as needed up to 40 mg/day; adjust dose based on response and tolerability (Ref).

Anxiety disorders (monotherapy or adjunctive therapy) (alternative agent):

Note: Generally used short term for symptom relief until preferred therapy (eg, serotonin reuptake inhibitor) is effective (eg, 4 to 6 weeks, followed by tapering). Long-term, low-dose (eg, 2.5 mg/day) therapy may be considered in select patients only when other treatments are ineffective or poorly tolerated (Ref). Use with caution in patients with posttraumatic stress disorder; benzodiazepines may worsen symptoms (Ref).

Initial: Oral: 2 to 5 mg once or twice daily; increase gradually based on response and tolerability up to 40 mg/day in 2 to 4 divided doses (Ref).

Procedural anxiety (premedication):

IV: 2 to 10 mg or 0.03 to 0.1 mg/kg once (maximum single dose: 10 mg) 5 to 15 minutes prior to procedure; if needed due to incomplete response and/or duration of procedure, may repeat the dose (usually 50% of the initial dose) after 5 to 30 minutes (Ref). Note: In obese patients, non-weight-based dosing is preferred (Ref).

Oral (off-label): 2 to 10 mg once 30 to 60 minutes prior to procedure; if needed due to incomplete response, may repeat the dose (usually 50% of the initial dose) after 30 to 60 minutes (Ref).

Hydroxychloroquine/chloroquine toxicity

Hydroxychloroquine/chloroquine toxicity (severe):

Note: Use is recommended in patients with severe toxicity (eg, hypotension, QTc prolongation, hypokalemia) in combination with other supportive measures (eg, mechanical ventilation, epinephrine, cardiovascular monitoring) (Ref).

IV: 2 mg/kg once administered over 30 minutes, followed by 1 to 2 mg/kg/day for 2 to 4 days (Ref).

Intoxication

Intoxication (cocaine, methamphetamine, and other sympathomimetics) (off-label use): Based on limited data.

IV: 2 to 10 mg every 3 to 10 minutes as needed for agitation, sedation, seizures, hypertension, and tachycardia until desired symptom control achieved; doses up to 20 mg may be considered in severe agitation based on response and tolerability. Large, cumulative doses may be required for some patients; monitor for respiratory depression and hypotension. Note : If IV access is not possible, consider IM administration; however, IM diazepam time to peak drug levels is slower than IM midazolam (Ref).

Muscle spasm, spasticity, and/or rigidity

Muscle spasm, spasticity, and/or rigidity (alternative agent):

Oral: Initial: 2 mg twice daily or 5 mg at bedtime; increase gradually based on response and tolerability, up to 40 to 60 mg/day in 3 to 4 divided doses (Ref).

Neuroleptic malignant syndrome

Neuroleptic malignant syndrome (adjunctive therapy) (off-label use):

Note: Following withdrawal of causative agent while continuing supportive care, use for moderate to severe muscle rigidity with elevated creatine kinase. May also use for any patient experiencing agitation (Ref).

IV: 10 mg every 8 hours until symptom resolution (Ref).

Seizures

Seizures:

Note: If IV access is not available, IM diazepam is not recommended due to erratic absorption and slow time to peak drug levels (IM midazolam is recommended) (Ref).

Acute active seizures (non-status epilepticus):

Intranasal: 0.2 mg/kg as a single dose; may repeat once based on response and tolerability after ≥4 hours. Maximum dose: Two doses per episode. Do not use for more than 1 episode every 5 days or more than 5 episodes per month.

The following table (derived from manufacturer labeling) provides acceptable weight ranges for each dose, such that patients will receive between 90% and 180% of the calculated recommended dose.

Rectal gel (generally for use in prehospital setting): 0.2 mg/kg (round dose up to the nearest 2.5 mg increment; maximum dose: 20 mg) or 10 to 20 mg as a single dose (Ref). Maximum duration: 5 episodes/month and 1 episode every 5 days (Ref).

Status epilepticus (alternative agent):

IV: 5 to 10 mg as a single dose given at a maximum infusion rate of 5 mg/minute; may repeat dose in 3 to 5 minutes if seizures continue; a nonbenzodiazepine antiseizure agent should follow to prevent seizure recurrence, even if seizures have ceased (Ref).

Rectal gel (generally for use in prehospital setting) (off-label): 0.2 to 0.5 mg/kg (round dose up to the nearest 2.5 mg increment; maximum dose: 20 mg) as a single dose (Ref).

Serotonin syndrome

Serotonin syndrome (serotonin toxicity) (off-label use):

IV: 5 to 10 mg every 8 to 10 minutes until symptoms resolve (Ref).

Substance withdrawal

Substance withdrawal:

Alcohol withdrawal syndrome:

Note: Withdrawal will progress at different rates in some patients; flexibility in dosing and duration is warranted (Ref). Regimens vary and depend on withdrawal history, degree of current withdrawal symptoms, blood alcohol concentration, and whether the patient is treated inpatient or in the ambulatory setting. Many facilities only treat alcohol withdrawal in the ambulatory setting if Clinical Institute Withdrawal Assessment for Alcohol, revised scale (CIWA-Ar) score is ≤15 (mild to moderate alcohol withdrawal) and there is no history of withdrawal seizures or delirium tremens (Ref). Some experts recommend avoiding IM administration due to variable absorption (Ref). The following are two suggested regimens.

Symptom-triggered regimen:

Note: Some experts recommend inpatient treatment and symptom-triggered dosing for patients with CIWA-Ar >15 (moderate to severe alcohol withdrawal) (Ref).

IV, Oral: 5 to 10 mg as needed per institution-specific protocol until appropriate sedation achieved; dose and frequency determined by withdrawal symptom severity using a validated severity assessment scale, such as the CIWA-Ar (Ref).

Fixed-dose regimen :

Note: Some experts recommend fixed-dose regimens for patients with CIWA-Ar ≤15 (mild to moderate alcohol withdrawal) (Holt 2023). In addition to scheduled doses shown in the example regimen below, provide up to 5 additional as-needed 10 mg doses to be used over the 4-day treatment period for symptom-triggered dosing (Holt 2023).

Day 1: Oral, IV: 10 mg every 6 hours (Holt 2023; WFSBP [Soyka 2017]).

Day 2: Oral, IV: 10 mg every 8 hours (Holt 2023; WFSBP [Soyka 2017]).

Day 3: Oral, IV: 10 mg every 12 hours (Holt 2023; WFSBP [Soyka 2017]).

Day 4: Oral, IV: 10 mg at bedtime, then discontinue diazepam (Holt 2023; WFSBP [Soyka 2017]).

Opioid withdrawal (autonomic instability and agitation) (alternative agent) (adjunctive therapy) (off-label use): Based on limited data.

IV: 10 to 20 mg every 5 to 10 minutes until hemodynamically stable and adequate sedation achieved (Ref).

Vertigo, acute episodes

Vertigo, acute episodes (alternative agent) (off-label use):

Note: Reserve use for symptomatic relief of episodes lasting several hours to days (maximum duration: 3 days); chronic use may impede adaptation and recovery (Ref).

IV, Oral: 1 to 5 mg every 12 hours as needed for up to 48 to 72 hours (Ref).

Discontinuation of therapy: Unless safety concerns require a more rapid withdrawal, gradually taper to detect reemerging symptoms and minimize rebound and withdrawal symptoms in patients receiving therapy ≥4 weeks or as appropriate based on patient-specific factors (Ref).

Low or moderate dose, no concerns for benzodiazepine use disorder: Taper total daily dose by 20% to 25% every week based on response and tolerability (taper increments will be limited by available dosage forms) (Ref).

Extended or high-dose therapy, or suspected benzodiazepine use disorder: Taper total daily dose by approximately 25% every 1 to 2 weeks based on response, tolerability, and individual patient factors (taper increments will be limited by available dosage forms) (Ref). Reduce dose more rapidly in the beginning, and slow the dose reduction as the taper progresses because earlier stages of withdrawal are easier to tolerate (Ref). The optimal duration and taper increment will vary; up to 6 months may be necessary for some patients on higher doses, and a taper rate of 50% every week may be tolerated in some patients (Ref).

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

Dosing: Kidney Impairment: Adult

The renal dosing recommendations are based upon the best available evidence and clinical expertise. Senior Editorial Team: Bruce Mueller, PharmD, FCCP, FASN, FNKF; Jason A. Roberts, PhD, BPharm (Hons), B App Sc, FSHP, FISAC; Michael Heung, MD, MS.

Note: An increased incidence of CNS-related adverse effects has been reported in patients with hypoalbuminemia (which is frequently observed in patients with end-stage kidney disease or critical illness) (Ref).

Altered kidney function: No dosage adjustment necessary for any degree of kidney impairment; use with caution, especially with prolonged courses (Ref).

Hemodialysis, intermittent (thrice weekly): Unlikely to be significantly dialyzable (highly protein bound, large Vd): No supplemental dose or dosage adjustment necessary; use with caution, especially with prolonged courses (Ref).

Peritoneal dialysis: Unlikely to be significantly dialyzable (highly protein bound, large Vd): No dosage adjustment necessary; use with caution, especially with prolonged courses (Ref).

CRRT: No dosage adjustment necessary; use with caution, especially with prolonged courses (Ref).

PIRRT (eg, sustained, low-efficiency diafiltration): No dosage adjustment necessary; use with caution, especially with prolonged courses (Ref).

Dosing: Hepatic Impairment: Adult

There are no dosage adjustments provided in the manufacturer's labeling; use with caution because distribution and half-life may increase, and clearance may decrease significantly. The oral tablets are contraindicated in severe hepatic impairment.

Warnings/Precautions

Concerns related to adverse effects:

• Anterograde amnesia: Benzodiazepines have been associated with anterograde amnesia (Nelson 1999).

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

• Paradoxical reactions: Paradoxical reactions, including hyperactive or aggressive behavior, have been reported with benzodiazepines; risk may be increased in adolescent/pediatric, 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).

• Suicidal ideation: Intranasal: Pooled analysis of trials involving various antiseizure medications (regardless of indication) showed an increased risk of suicidal thoughts/behavior (incidence rate: 0.43% of treated patients compared to 0.24% of patients receiving placebo); risk observed as early as 1 week after initiation and continued through duration of trials (most trials ≤24 weeks). Monitor all patients for notable changes in behavior that might indicate suicidal thoughts or depression; notify health care provider immediately if symptoms occur.

Disease-related concerns:

• Convulsive disorders: When used as an adjunct in treating convulsive disorders, an increase in frequency/severity of tonic-clonic seizures may occur and require dose adjustment of antiseizure medication. Abrupt withdrawal may result in a temporary increase in the frequency and/or severity of seizures.

• Depression: Avoid use in patients with depression because of concerns about worsening mood symptoms, particularly if suicidal risk may be present, except for acute or emergency situations (eg, acute agitation, status epilepticus) (Craske 2022).

• Glaucoma: May be used in patients with open-angle glaucoma who are receiving appropriate therapy; contraindicated in acute narrow-angle glaucoma and untreated open-angle glaucoma.

• Hepatic impairment: Use with caution in patients with hepatic impairment. Oral tablet is contraindicated in patients with severe hepatic impairment.

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

• Respiratory disease: Reduce dose or avoid use in patients with respiratory disease, including chronic obstructive pulmonary disease or sleep apnea. Benzodiazepines may cause significant respiratory depression. Oral tablet is contraindicated in patients with severe respiratory impairment or sleep apnea syndrome.

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, and 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; active metabolites with extended half-lives may lead to delayed accumulation and adverse effects; limit dose to smallest effective amount and increase gradually and as tolerated to avoid adverse reactions.

• Older adult patients: Use with caution; active metabolites with extended half-lives may lead to delayed accumulation and adverse effects; limit dose to smallest effective amount and increase gradually and as tolerated to avoid adverse reactions. Older adults may be at an increased risk of death with use; risk has been found highest within the first 4 months of use in older adult 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).

• Obese patients: Use benzodiazepines with caution in obese patients; may have prolonged action when discontinued.

• Psychotic patients: Use of diazepam is not recommended in place of appropriate therapy.

Dosage form specific issues:

• Benzyl alcohol and derivatives: Some dosage forms may contain benzyl alcohol and/or sodium benzoate/benzoic acid; benzoic acid (benzoate) is a metabolite of benzyl alcohol; large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity ("gasping syndrome") in neonates; the "gasping syndrome" consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension, and cardiovascular collapse (AAP ["Inactive" 1997]; CDC 1982); some data suggest that benzoate displaces bilirubin from protein binding sites (Ahlfors 2001); avoid or use dosage forms containing benzyl alcohol and/or benzyl alcohol derivative with caution in neonates. See manufacturer's labeling.

• Parenteral: Vesicant; ensure proper needle or catheter placement prior to and during administration; avoid extravasation. Acute hypotension, muscle weakness, apnea, and/or cardiac arrest have occurred with parenteral administration. Acute effects may be more prevalent in patients receiving concurrent barbiturates, opioids, or ethanol. Appropriate resuscitative equipment and qualified personnel should be available during administration and monitoring. Avoid use of the injection in patients in shock, coma, or in acute ethanol intoxication with depression of vital signs. Intra-arterial injection should be avoided. Tonic status epilepticus has been precipitated in patients treated with diazepam IV for absence status or absence variant status.

• Propylene glycol: Some dosage forms may contain propylene glycol; large amounts are potentially toxic and have been associated with hyperosmolality, lactic acidosis, seizures, and respiratory depression; use caution (AAP ["Inactive" 1997]; Wilson 2000; Wilson 2005; Zar 2007).

• Rectal gel: Administration of rectal gel should only be performed by individuals trained to recognize characteristic seizure activity for which the product is indicated, and capable of monitoring response to determine need for additional medical intervention. Not recommended for chronic, daily use. Use with caution in patients with neurologic damage.

Other warnings/precautions:

• Abuse, misuse, and substance use disorder: [US Boxed Warning]: The use of benzodiazepines, including diazepam, 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. Assess each patient's risk for abuse, misuse, and addiction prior to and throughout treatment; counsel patients at increased risk on proper use and monitoring for signs and symptoms of abuse, misuse, and substance use disorder. Institute early treatment or refer patients in whom substance use disorder is suspected. Limit dosages and durations to the minimum required.

• Appropriate use: Does not have analgesic, antidepressant, or antipsychotic properties.

• Dependence and withdrawal reactions: [US Boxed Warning]: The continued use of benzodiazepines, including diazepam, 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 diazepam 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 diazepam or reduce the dosage. Some patients may develop a protracted withdrawal syndrome lasting >12 months; may be difficult to differentiate withdrawal symptoms from reemergence or continuation of symptoms for which benzodiazepines were prescribed. Flumazenil may cause withdrawal in patients receiving long-term benzodiazepine therapy.

• Tolerance: Diazepam is a long half-life benzodiazepine. Duration of action after a single dose is determined by redistribution rather than metabolism. Tolerance develops to the sedative, hypnotic, and antiseizure effects. It does not develop to the anxiolytic or skeletal muscle relaxing effects (Vinkers 2012). Chronic use of this agent may increase the perioperative benzodiazepine dose needed to achieve desired effect.

Warnings: Additional Pediatric Considerations

Neonates and young infants have decreased metabolism of diazepam and desmethyldiazepam (active metabolite), both can accumulate with repeated use and cause increased toxicity.

Some dosage forms may contain propylene glycol; in neonates, large amounts of propylene glycol delivered orally, intravenously (eg, >3,000 mg/day), or topically have been associated with potentially fatal toxicities which can include metabolic acidosis, seizures, renal failure, and CNS depression; toxicities have also been reported in children and adults including hyperosmolality, lactic acidosis, seizures, and respiratory depression; use caution (AAP 1997; Shehab 2009). Diazepam Intensol Oral Solution (Concentration) contains 19% alcohol.

Medication Safety Issues
Sound-alike/look-alike issues:

DiazePAM may be confused with diazoxide, dilTIAZem, Ditropan, LORazepam

Valium may be confused with Valcyte

Older Adult: High-Risk Medication:

Beers Criteria: Diazepam is identified in the Beers Criteria as a potentially inappropriate medication to be avoided in patients 65 years and older due to risk of abuse, misuse, physical dependence, and addiction. In addition, older adults have an increased risk of impaired cognition, delirium, falls, fractures, and motor vehicle accidents with benzodiazepine use, and slower metabolism of long-acting benzodiazepines (eg, diazepam). However, benzodiazepines may be appropriate in the elderly when used for seizure disorders, rapid eye movement sleep behavior disorder, benzodiazepine or ethanol withdrawal, severe generalized anxiety disorder, or periprocedural anesthesia (Beers Criteria [AGS 2023]).

Metabolism/Transport Effects

Substrate of CYP1A2 (minor), CYP2B6 (minor), CYP2C19 (major), CYP2C9 (minor), CYP3A4 (major); Note: Assignment of Major/Minor substrate status based on clinically relevant drug interaction potential

Reproductive Considerations

Evaluate pregnancy status prior to use. Pregnancy testing is recommended before treating acute alcohol withdrawal symptoms (ASAM 2020).

Therapy for anxiety should be individualized (BAP [McAllister-Williams 2017]); avoid the use of benzodiazepines for the treatment of anxiety disorders in patients planning to become pregnant (Larsen 2015).

Pregnancy Considerations

Diazepam and its metabolites (N-desmethyldiazepam, temazepam, and oxazepam) cross the placenta (Kanto 1982; McElhatton 1994).

In-utero exposure to benzodiazepines has the potential to cause harm to the fetus. Teratogenic effects have been observed in some studies; however, a clear association has not been reported and additional data are needed (Bellantuono 2013; Freeman 2018; Grigoriadis 2019; Noh 2022; Szpunar 2022; Tinker 2019; Wikner 2007). Exposure to a benzodiazepine late in pregnancy may cause neonatal sedation (hypotonia, lethargy, respiratory depression) and/or symptoms of neonatal withdrawal (feeding difficulties, hyperreflexia, inconsolable crying, irritability, restlessness, tremors). Data related to long-term effects on neurodevelopment are inconclusive (Chen 2022; Radojčić 2017; Sundbakk 2022; Wang 2022). Newborns exposed to diazepam in utero should be monitored for feeding problems, respiratory depression, sedation, and withdrawal.

Treatment for alcohol withdrawal may be considered for pregnant patients with at least moderate symptoms (CIWA-Ar scores ≥10) (ASAM 2020). The short-term use of a long-acting benzodiazepine may be used in pregnant patients requiring treatment of acute alcohol withdrawal symptoms (WHO 2014); however, the use of shorter-acting benzodiazepines is preferred in patients at risk for preterm delivery or when treatment is needed during the third trimester (ASAM 2020). Although recommendations vary by guideline, the use of diazepam may be considered when treating pregnant patients (BAP [McAllister-Williams 2017]; SOGC [Graves 2020]; WFSBP/IAWMH [Thibaut 2019]). Monitor newborns for fetal alcohol spectrum disorders in addition to benzodiazepine intoxication (ASAM 2020).

Therapy for anxiety during pregnancy should be individualized. Untreated or inadequately treated psychiatric illness may lead to poor adherence to prenatal care and adverse pregnancy outcomes (ACOG 2008). Benzodiazepines are not preferred when pharmacologic treatment for anxiety disorders is needed during pregnancy (BAP [McAllister-Williams 2017]; Larsen 2015); however, if a benzodiazepine is needed, diazepam may be considered for the treatment of anxiety in pregnant patients (based on the trimester of exposure). If possible, avoid scheduled doses of benzodiazepines in the month prior to delivery to reduce the risk of withdrawal symptoms in the newborn (Larsen 2015).

When treating pregnant patients for seizure disorders, monotherapy with the lowest effective dose and avoidance of medications known to have a high incidence of teratogenic effects is recommended (Harden 2009; Wlodarczyk 2012).

Data collection to monitor pregnancy and infant outcomes following exposure to diazepam is ongoing. Health care providers are encouraged to enroll patients exposed to diazepam during pregnancy in the National Pregnancy Registry for Psychiatric Medications (866-961-2388) or the North American Antiepileptic Drug (NAAED) Pregnancy Registry (888-233-2334).

Monitoring Parameters

Heart rate, respiratory rate, blood pressure, mental status; with long-term therapy: Liver enzymes, CBC

Mechanism of Action

Long-acting benzodiazepine. Binds to stereospecific benzodiazepine receptors on the postsynaptic GABA neuron at several sites within the central nervous system, including the limbic system, 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.

Pharmacokinetics (Adult Data Unless Noted)

Onset of action:

Sedation: Pediatric patients: IV: 4 to 5 minutes (Krauss 2006).

Status epilepticus: IV: 1 to 3 minutes; Rectal: 2 to 10 minutes.

Duration of action:

Classified as a long-acting benzodiazepine; classification based on benzodiazepines with half-life >40 hours (Griffin 2013).

Indication-specific durations:

Sedation: Pediatric patients: IV: 60 to 120 minutes (Krauss 2006).

Absorption:

Oral: Well absorbed (>90%); delayed and decreased when administered with a moderate fat meal.

Rectal: Well absorbed.

Distribution: Vd:

Intranasal: 0.8 to 1 L/kg.

IV: 1.2 L/kg (range: 0.6 to 2 L/kg) (Greenblatt 1989a).

Oral: 1.1 L/kg (range: 0.6 to 1.8 L/kg (Greenblatt 1989b).

Rectal: 1 L/kg.

Protein binding:

Intranasal: 95% to 98%.

Oral: Neonates: 84% to 86% (Milsap 1994; Morselli 1980); Adults: 98%.

Rectal: 95% to 98%.

Metabolism: Hepatic; diazepam is N-demethylated by CYP3A4 and 2C19 to the active metabolite N-desmethyldiazepam, and is hydroxylated by CYP3A4 to the active metabolite temazepam. N-desmethyldiazepam and temazepam are both further metabolized to oxazepam. Temazepam and oxazepam are largely eliminated by glucuronidation.

Bioavailability:

IM: >90% (Lamson 2011).

Intranasal: 97%.

Oral: >90%.

Rectal: 90%.

Half-life elimination: Note: Diazepam accumulates upon multiple dosing and the terminal elimination half-life is slightly prolonged.

IM:

Premature neonates (GA: 28 to 34 weeks): 54 hours.

Infants: ~30 hours (Morselli 1973).

Children 3 to 8 years: 18 hours (Morselli 1973).

Adults: Parent: ~60 to 72 hours; Desmethyldiazepam: ~152 to 174 hours (Lamson 2011).

Intranasal: ~49 hours.

IV: Parent: 33 to 45 hours; Desmethyldiazepam: 87 hours (Cloyd 1998; Greenblatt 1989a).

Oral: Parent: 44 to 48 hours; Desmethyldiazepam: 100 hours (Greenblatt 1989b).

Rectal: Parent: 45 to 46 hours; Desmethyldiazepam: 71 to 99 hours (Cloyd 1998).

Time to peak:

IM: Median: 1 hour (range: 0.25 to 2 hours) (Lamson 2011).

Intranasal: ~1.5 hours.

IV: ~1 minute (Cloyd 1998).

Oral: 15 minutes to 2.5 hours (1.25 hours when fasting; 2.5 hours with food) (Greenblatt 1989b).

Rectal: 1.5 hours.

Excretion: Urine (predominantly as glucuronide conjugates).

Pharmacokinetics: Additional Considerations (Adult Data Unless Noted)

Hepatic function impairment: In mild and moderate cirrhosis, the average half-life increases 2- to 5-fold, with individual half-lives over 500 hours reported. There is also an increase in volume of distribution, and average clearance decreases by almost half. Half-life is also prolonged with hepatic fibrosis to 90 hours (range: 66 to 104 hours), with chronic active hepatitis to 60 hours (range: 26 to 76 hours), and with acute viral hepatitis to 74 hours (range: 49 to 129 hours). In chronic active hepatitis, clearance is decreased by almost half.

Older adult: The half-life is increased by approximately 1 hour for each year of age beginning with a half-life of 20 hours at 20 years of age, as the volume of distribution is increased, and clearance is decreased. Consequently, there may be lower peak concentrations, higher trough concentration with multiple doses, and it may take longer to reach steady state.
