Management of Insomnia01:19

Management of Insomnia

778
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

476
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

4.7K
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...

Biological Clocks and Seasonal Responses

42.1K
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Sedatives and Hypnotics Drugs: Miscellaneous Agents01:17

Sedatives and Hypnotics Drugs: Miscellaneous Agents

849
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...

Area of Science:

  • Psychiatry
  • Chronobiology
  • Sleep Medicine

Background:

  • Mood disorders often present with significant challenges, including drug resistance.
  • Current treatments may have limited efficacy or undesirable side effects.
  • Chronobiological interventions offer novel therapeutic avenues.

Purpose of the Study:

  • To review the principles and latest findings in clinical chronobiology for mood disorders.
  • To highlight the efficacy and safety of chronobiological therapies.
  • To discuss their role as standalone or adjunctive treatments.

Main Methods:

  • Review of existing literature on chronobiological therapies.
  • Analysis of sleep-wake cycle manipulations (e.g., sleep deprivation, phase advance).
  • Examination of controlled light and darkness exposure protocols.

Main Results:

  • Chronobiological therapies demonstrate rapid and sustained antidepressant effects.
  • Efficacy is comparable to established psychiatric treatments.
  • These therapies can overcome drug resistance and address core depressive symptoms, including suicidality.
  • Side effects are typically marginal or absent.

Conclusions:

  • Chronobiological therapies are effective standalone or adjunctive treatments for mood disorders.
  • They offer a promising option for drug-resistant depression.
  • New protocols are being developed for diverse clinical settings.
