Summary
This study presents an algorithm for managing insomnia secondary to psychiatric disorders. Evidence-based psychopharmacology is recommended over solely treating insomnia as a symptom.
Area of Science:
- Psychiatry
- Sleep Medicine
- Pharmacology
Background:
- Insomnia is a common symptom associated with various medical and psychiatric conditions.
- While treatments for primary insomnia are established, evidence for treating secondary insomnia is less recognized.
- Secondary insomnia often accompanies psychiatric disorders, necessitating specific management strategies.
Purpose of the Study:
- To provide an evidence-based algorithm for the psychopharmacological management of insomnia secondary to common psychiatric disorders.
- To guide clinicians in selecting appropriate treatments for complex insomnia cases.
- To highlight the importance of addressing the underlying psychiatric condition in treating insomnia.
Main Methods:
- Development of a new algorithm by the Psychopharmacology Algorithm Project at Harvard South Shore Program.
- Review of existing algorithms for psychiatric disorders and relevant controlled trials, reviews, and meta-analyses.
- Focus on insomnia secondary to or accompanying major depressive disorder, generalized anxiety disorder, post-traumatic stress disorder, and bipolar mania.
Main Results:
- A comprehensive biopsychosocial evaluation is the crucial first step in managing insomnia.
- Specific pharmacologic recommendations include eszopiclone and trazodone for major depressive disorder, eszopiclone and zolpidem for generalized anxiety disorder, prazosin for PTSD, and second-generation antipsychotics for bipolar mania.
- Non-pharmacological treatments are recommended for conditioned insomnia, and priority is given to the condition causing greater disability when multiple disorders are present.
Conclusions:
- Insomnia is frequently multifactorial, often linked to underlying psychiatric conditions.
- Evidence-supported psychopharmacology offers effective approaches for insomnia secondary to psychiatric disorders.
- Treating the underlying psychiatric disorder is essential for effectively managing secondary insomnia.

01:19Management of Insomnia
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...
01:17Sedatives and Hypnotics Drugs: Miscellaneous Agents
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

01:27Insomnia
Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.

01:23Antidepressant Drugs: MAOIs and Other Agents
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...
01:26Psychosis: Goals of Pharmacotherapy
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation. For...
01:23Sedatives and Hypnotics: Overview
Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
