Study Notes
Definition of Insomnia
- Insomnia is characterized by subjective difficulty in sleep initiation, duration, consolidation, or quality despite adequate sleep opportunities, often leading to daytime impairment.
First-Line Therapies for Insomnia
- Nonpharmacologic treatments include methods like stimulus control, relaxation training, and sleep restriction.
Gender Differences in Insomnia
- Women exhibit a higher prevalence of insomnia, particularly during hormonal changes such as pregnancy (third trimester) and post-menopause.
Benzodiazepines Mechanism
- Benzodiazepines modulate GABA receptors, leading to hyperpolarization of neurons and decreased neuronal excitability, thereby promoting better sleep.
Role of GABA
- GABA functions as an inhibitory neurotransmitter in the central nervous system. It reduces neuronal excitability, facilitating a more restful sleep.
GABA and Amnesia
- GABA can cause retrograde amnesia, a condition where individuals cannot recall events from before a specific time, particularly concerning events prior to medication intake.
Dependence on Benzodiazepines
- Physical dependence on benzodiazepines is considered high, indicating potential risks with prolonged use.
Contraindications of Benzodiazepines
- Benzodiazepines are contraindicated during pregnancy and breastfeeding due to potential risks to the fetus and infant.
Z-Drugs
- Z-drugs, including zaleplon (Sonata), zolpidem (Ambien), and eszopiclone (Lunesta), are commonly prescribed non-benzodiazepine medications that enhance GABA effects to promote sleep.
Zolpidem
- Zolpidem is an imidazopyridine agent effective for treating circadian rhythm misalignment and high-altitude insomnia.
Eszopiclone
- Eszopiclone, a cyclopyrrolone drug, is suited for improving sleep maintenance due to its long half-life.
Zaleplon
- Zaleplon is a pyrazolopyrimidine drug noted for its extremely short half-life, primarily aiding in improving sleep latency rather than maintenance.
Role of Melatonin
- Melatonin regulates the sleep-wake cycle; disruption in its production or timing can lead to insomnia, particularly as melatonin levels decrease with age, contributing to sleep difficulties in older adults.
Ramelteon
- Ramelteon is a melatonin agonist approved for treating insomnia associated with sleep latency.
Doxepin
- Doxepin (Silenor) is the only tricyclic antidepressant FDA-approved for insomnia, showing improved sleep outcomes with minimal adverse effects compared to placebo.
Antihistamines for Pregnancy-Related Insomnia
- Diphenhydramine and Doxylamine are recommended for treating pregnancy-related insomnia, with Doxylamine being effective for nausea and considered safe during pregnancy.
Antipsychotics for Insomnia
- Olanzapine (Zyprexa), quetiapine (Seroquel), and risperidone (Risperdal) are antipsychotics used to treat insomnia, reserved for cases associated with bipolar disorder.
Suvorexant
- Suvorexant is the first orexin receptor antagonist approved for insomnia treatment, targeting the mechanisms of wakefulness.
Anti-Epileptic Drugs
- Gabapentin and Pregabalin have been identified as improving sleep, though their precise mechanisms remain unclear.
Main Treatment Approach for Insomnia
- Behavioral interventions are regarded as the primary treatment modality for insomnia, emphasizing nonpharmacologic strategies.
