What is first-line insomnia therapy?

1. Cognitive-behavioral therapy for insomnia (CBT-I)

2. Pharmacotherapy – wisely applied

#1: Do incorporate cognitive and behavioral strategies into your practice

When a patient fails first-line insomnia therapy

Cognitive-Behavioral Therapy for Insomnia (CBT-I)• Evidence-based

– Traditional CBT-I• 6 to 8 individual or group sessions with certified therapist, typically

manualized• Multimodal intervention

– Sleep hygiene education– Cognitive strategies– Sleep restriction– Stimulus control– Relaxation– Paradoxical intention

• Durable improvements in sleep onset and maintenance• Limited availability of providers in many areas

van Straten A, et al. Sleep Med Rev. 2018;38:3-16.

Alternate Cognitive and Behavioral Approaches• Evidence-based

– Brief Behavioral Treatment of Insomnia (BBTI)• 4-session manualized treatment approach

–2 face-to-face–2 by telephone

• Non-psychologist health professional• Performed in general medical settings• Behavioral guidelines targeting homeostatic and circadian

drives• Improvement in sleep onset and maintenance

Gunn HE, et al. Sleep Med Clin. 2019;14(2):235-243.

Alternate Cognitive and Behavioral Approaches (cont’d)

• Available strategies– Online CBT-I– Telephone CBT-I– CBT-I apps– Self-help CBT-I books– Smartphone apps with education and guidelines– Monitoring apps with providing feedback and recommendations

#2: Don’t fail to do a detailed insomnia history

Key Insomnia History Assessments• Primary insomnia complaint

– Nighttime symptoms– Daytime/evening symptoms

• Course of sleep disturbance• Sleep-wake schedule• Additional sleep-related symptoms• Medication and substance use

American Psychiatric Association. Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Arlington, VA: American Psychiatric Association Publishing; 2013. Schutte-Rodin S, et al. J Clin Sleep Med. 2008;4(5):487-504. Morin CM, et al. Lancet. 2012;379(9821):1129-1141.

#3: Do have patients maintain sleep diaries or sleep logs

Helpful for initial diagnosisImportant for differential diagnosis

Useful for monitoring treatment efficacyNew options: Online, apps, and trackers (wearables, nearables)

#4: Don’t fail to consider sleep-disordered breathing in patients complaining of insomnia

Obstructive sleep apneaCentral sleep apnea

Sleep-related hypoventilation

STOP-BANG OSA Screen

OSA = obstructive sleep apnea.Nagappa M, et al. PLoS One. 2015;10(12):e0143697.

Have you been told that you snore?

Are you tired during the day?

Do you know if you stop breathing or has anyone witnessed you stop breathing while you are asleep?

Do you have high blood pressure or on medication to control high blood pressure?

Y/NAnswering Yes to ≥ 2 indicates risk for OSA

STOP-BANG OSA Screen (cont’d)

Nagappa M, et al. PLoS One. 2015;10(12):e0143697.

Is you body mass index greater than 28?

Are you 50 years old or older?

Are you a male with a neckcircumference > 17 inches, or a female with a neck circumference > 16 inches?

Are you a male?

Y/NThe more Yes answers, the greater the OSA severity

#5: Don’t assume that more is better whenprescribing sedating medications

2001 mgChiaro G, et al. J Clin Sleep Med. 2018;14(7):1257-1259.

#6: Do think carefully about prescribing trazodone

Trazodone: Highlights of Prescribing Information• Indications and Usage: “a selective serotonin reuptake inhibitor

indicated for the treatment of major depressive disorder (MDD)”• Dosage and Administration

– Maximum dose: 400 mg/day in divided doses– Should be taken shortly after a meal– When discontinued, gradual doses reduction is recommended

US Food and Drug Administration. Drugs@FDA: FDA Approved Drug Products. www.accessdata.fda.gov/scripts/cder/daf/.

Trazodone: Pharmacology• Pharmacodynamics

– 5-HT2A antagonist (Ki = 35.6 nM)– 5-HT2B antagonist (Ki = 78.4 nM)– 5-HT2C antagonist (Ki = 224 nM)– Serotonin reuptake inhibition (Ki = 367 nM)– α1A antagonist (Ki = 153 nM)– α2C antagonist (Ki = 155 nM)– 5-HT1A partial agonist (Ki = 118 nM)

• Pharmacokinetics– Peak plasma level (empty stomach) approximately 1 hour– Elimination half-life: Biphasic 10–12 hours– Active metabolite (CYP3A4): m-chlorophenylpiperazine (mCPP)

US Food and Drug Administration. Drugs@FDA: FDA Approved Drug Products. www.accessdata.fda.gov/scripts/cder/daf/.Bryant SG, et al. Clin Pharm. 1982;1(5):406-417.

Trazodone: Highlights of Prescribing InformationWarnings and Precautions

• Suicidal thoughts and behaviors• Serotonin syndrome• Cardiac arrhythmias: Increases the QT interval• Orthostatic hypotension and syncope• Increased risk of bleeding• Priapism (including clitoral priapism*)• Activation of mania or hypomania• Potential for cognitive and motor impairment• Angle-closure glaucoma• Hyponatremia

US Food and Drug Administration. Drugs@FDA: FDA Approved Drug Products. www.accessdata.fda.gov/scripts/cder/daf/.*Battaglia C, et al. J Sex Med. 2009;6(10):2896-900. Medina CA. Obstet Gynecol. 2002;100(5 Pt 2):1089-1091.

Trazodone: Potential Drug Interactions• Central nervous system depressants• Strong CYP3A4 inhibitors

– Consider trazodone dose reduction– Examples: itraconazole, ketoconazole, clarithromycin, and indinavir

• Strong CYP3A4 inducers– Consider trazodone dose increase– Examples: rifampin, carbamazepine, phenytoin, St. John’s wort

• QT interval prolongation: Avoid in combination with drugs known to prolong the QTc– Class 1A antiarrhythmics: quinidine, procainamide, disopyramide– Class 3 antiarrhythmics: amiodarone, sotalol– Antipsychotics: ziprasidone, chlorpromazine, thioridazine– Antibiotics: gatifloxacin

“mCPP has psychostimulant, anxiety-provoking and hallucinogenic effects.”

“Among patients with psychiatric disorders a greater degree of anxiety, euphoria, perceptual changes, and hostility were observed compared

with healthy control subjects…”

Bossong MG, et al. J Psychopharmacol. 2010;24(9):1395-1401.

High and clinically significant daytime m-CPP levels (about 100 ng/ml or a tenth of plasma trazodone levels) continue to be documented in normal humans taking a common trazodone dose for sleep, 150 mg once at

bedtime (Mercolini et al. 2008). This is comparable to levels attained when anxiety or panic attacks are provoked by i.v. m-CPP in studies with normal human volunteers (Van Veen et al. 2007).

Kast RE. World J Biol Psychiatry. 2009;10(4 Pt 2):682-685.

New use of low-dose trazodone was no safer with regard to a risk of a fall-related injury than new use of benzodiazepines.

Bronskill SE, et al. J Am Geriatr Soc. 2018;66(10):1963-1971.

differential diagnosis

Insomnia Disorder Differential Diagnosis• Normal variant – short sleeper• Chronic volitional sleep restriction• Sleep-disruptive environmental

circumstances• Comorbid psychiatric disorders (eg,

mood and anxiety)• Substance/medication-induced

sleep disorder, insomnia type• Circadian rhythm sleep-wake

disorders, especially– Delayed sleep phase– Advanced sleep phase

• Breathing-related sleep disorders– OSA– Central sleep apnea– “Complex insomnia”

• Parasomnias– REM-related disorders

• Nightmares• REM sleep behavior disorder

– Non-REM arousal disorders• Sleep terrors• Confusional arousals

• RLSREM = rapid eye movement; RLS = restless legs syndrome.International Classification of Sleep Disorders. Third Edition. Darien, IL: American Academy of Sleep Medicine; 2014. American Psychiatric Association. Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Arlington, VA: American Psychiatric Association Publishing; 2013.

Restless Legs Syndrome• Key characteristics

– Uncomfortable and unpleasant urge to move the legs• Starts or worsens during rest or inactivity• Relieved by movement• Worse or occurs only during the evening or nighttime

– At least 3×/week for at least 3 months– Significant distress or impairment– Not attributable to another mental disorder, medical condition, behavioral

condition, substance, or medication (akathisia!)• Common associated features

– Periodic leg movements in sleep – up to 90% of those diagnosed with RLS –significance depends on sleep study rate associated with arousals

– Insomnia– Daytime sleepiness
