Management of Insomnia01:19

Management of Insomnia

332
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

148
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...

Sedatives and Hypnotics Drugs: Miscellaneous Agents

262
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...

Circadian Rhythms and Gene Regulation02:19

Circadian Rhythms and Gene Regulation

4.2K
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...

Understanding Sleep01:11

Understanding Sleep

707
Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...

Insomnia01:27

Insomnia

142
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.
Multiple factors contribute...

Area of Science:

  • Pharmacology
  • Sleep Medicine
  • Chronobiology

Background:

  • Exogenous melatonin (exo-MEL) use for sleep is inconsistent.
  • Understanding exo-MEL's sleep-promoting effects requires systematic review.

Approach:

  • Comprehensive literature review of exo-MEL's chronobiotic and sleep properties.
  • Analysis of pharmacological mechanisms and clinical outcomes.
  • Focus on administration timing and dosage.

Key Points:

  • exo-MEL's effects vary across healthy subjects, circadian rhythm sleep disorders, and primary insomnia.
  • Administration timing and dosage significantly influence exo-MEL's efficacy.
  • Interpreting exo-MEL effects requires considering endogenous melatonin dynamics.

Conclusions:

  • Personalized application of exo-MEL in clinical practice needs further consideration.
  • Evidence supports exo-MEL's role in specific sleep conditions when appropriately timed.
  • Further research should clarify optimal exo-MEL protocols for diverse patient populations.
