What are the treatment options for insomnia, including sleeping pills like zolpidem (non-benzodiazepine hypnotic) and eszopiclone?

Treatment Options for Insomnia

Cognitive Behavioral Therapy for Insomnia (CBT-I) should be considered the first-line treatment for adults with chronic insomnia disorder, with pharmacological therapy reserved as second-line treatment only when CBT-I alone is unsuccessful. 1, 2

First-Line Treatment: Non-Pharmacological Approaches

• CBT-I has demonstrated superior long-term efficacy compared to pharmacological options and carries minimal risk of adverse effects 1
• CBT-I components include cognitive therapy, behavioral interventions (such as sleep restriction and stimulus control), and educational interventions 1, 2
• Other effective behavioral interventions include multicomponent behavioral therapy, stimulus control, relaxation strategies, and sleep restriction therapy 2
• Although sleep hygiene alone is insufficient for treating chronic insomnia, it should be used in combination with other therapies 2, 3
• Physical activity may improve sleep quality and should be considered as part of a comprehensive treatment plan 2

Second-Line Treatment: Pharmacological Options

When CBT-I is insufficient alone, pharmacological options can be considered in the following sequence:

1. Non-Benzodiazepine Receptor Agonists (First Choice)

• Short-to-intermediate acting agents like zolpidem, eszopiclone, and zaleplon are recommended as first-line pharmacological treatments 2
• Eszopiclone is FDA-approved for decreasing sleep latency and improving sleep maintenance for up to 6 months 4
• Zolpidem is indicated for the short-term treatment of insomnia characterized by difficulties with sleep initiation 5
• These medications should be used at the lowest effective dose for the shortest duration possible (ideally ≤4-5 weeks) 1, 4

2. Melatonin Receptor Agonists

• Ramelteon can be considered as an alternative first-line agent, particularly for sleep onset insomnia 2, 1
• It has lower abuse potential compared to other sleep medications, making it suitable for patients with substance use history 1

3. Sedating Antidepressants

• Low-dose doxepin, trazodone, mirtazapine, and amitriptyline may be considered when first-line treatments fail or when comorbid depression exists 2, 1
• These should be used at lower than antidepressant doses when targeting insomnia symptoms 6

Medication Selection Considerations

• Choice of specific medication should be directed by symptom pattern, treatment goals, past responses, patient preference, comorbidities, and potential side effects 2
• For sleep onset insomnia: Consider zaleplon (shortest-acting) or zolpidem 2, 7
• For sleep maintenance insomnia: Consider eszopiclone or extended-release zolpidem 2, 4
• For elderly patients: Use reduced doses (e.g., 5mg zolpidem instead of 10mg) due to increased sensitivity to side effects 6, 7

Safety Considerations and Adverse Effects

• Non-benzodiazepine hypnotics may cause serious side effects including:

  • Complex sleep behaviors (sleep-walking, sleep-driving, sleep-eating) 4, 7
  • Morning impairment of driving and cognitive function 4, 8
  • Increased risk of falls and fractures, particularly in the elderly 7
  • Potential for dependence and withdrawal symptoms 9

• Zolpidem has been associated with:

  • Increased risk of falls (OR 4.28) 7
  • Higher risk of hip fractures (RR 1.92) 7
  • CNS-related adverse events like confusion and dizziness 7

• Eszopiclone and zopiclone commonly cause bitter aftertaste but may have fewer cognitive effects than benzodiazepines 8, 10

Treatment Algorithm

1. Start with CBT-I as first-line treatment 1, 2
2. If CBT-I alone is insufficient after 4-6 weeks:
   • Add a non-benzodiazepine receptor agonist (zolpidem, eszopiclone, zaleplon) 2
   • Use at lowest effective dose for shortest duration (≤4-5 weeks) 1
3. If first-line medication is ineffective:
   • Try an alternative non-benzodiazepine agent or ramelteon 2
4. If still ineffective:
   • Consider low-dose sedating antidepressants 2, 1
5. Continue to incorporate behavioral techniques even when using medications 1
6. Monitor regularly for treatment response, adverse effects, and potential misuse 2

Special Populations

• Elderly patients: Use reduced doses of medications; consider ramelteon due to lower fall risk 6, 7
• Patients with substance use history: Consider ramelteon due to lower abuse potential 1
• Cancer survivors: CBT-I has shown particular efficacy in this population 2
