Management of Insomnia01:19

Management of Insomnia

229
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...

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

41
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

Circadian Rhythms and Gene Regulation

4.0K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Mania and Antimanic Drugs: Overview

119
Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as...

Antidepressant Drugs: MAOIs and Other Agents

183
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...

Sedatives and Hypnotics Drugs: Miscellaneous Agents

144
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...

Summary

Chronotherapeutics, using light and sleep manipulation, offer a safe and effective non-drug treatment for mood disorders. These therapies show promise for treatment-resistant depression and may become first-line options.

Area of Science:

  • Psychiatry and Behavioral Science
  • Sleep Medicine
  • Chronobiology

Background:

  • Mood disorders are often linked to disruptions in sleep and circadian rhythms.
  • Chronotherapeutics emerged from research into these biological abnormalities.
  • Non-pharmacologic interventions are increasingly sought for mood disorders.

Purpose of the Study:

  • To review the development and application of chronotherapeutics.
  • To highlight the safety and efficacy of these non-drug interventions.
  • To explore the potential of chronotherapeutics in treating mood disorders, including treatment-resistant depression.

Main Methods:

  • Controlled exposure to environmental cues like light and darkness.
  • Sleep-wake manipulations, including partial/total sleep deprivation and sleep phase adjustment.
  • Light therapy approaches.

Main Results:

  • Chronotherapeutics demonstrate growing evidence of safety and efficacy in clinical practice.
  • These therapies effectively target core depressive symptoms, such as suicidality.
  • They offer a viable monotherapy or adjunctive treatment option.

Conclusions:

  • Chronotherapeutics represent a novel therapeutic strategy for mood disorders.
  • Their efficacy in treatment-resistant depression warrants further investigation.
  • These non-pharmacologic interventions may be considered for first-line treatment of mood disorders.
