Summary
Melatonin, a key sleep hormone, has limitations as a drug. New melatonin receptor agonists show promise for treating sleep, neuropsychiatric, and metabolic disorders.
Area of Science:
- Chronobiology
- Neuropharmacology
- Endocrinology
Background:
- Melatonin (N-acetyl-5-methoxytryptamine) regulates circadian rhythms and sleep-wake cycles.
- It possesses cyto/neuroprotective, immune modulatory, and metabolic functions.
- Melatonin's therapeutic use is limited by its short half-life and poor bioavailability.
Purpose of the Study:
- To review recent advances in the development of investigational melatonergic drugs.
- To highlight novel agents targeting melatonin receptors for therapeutic applications.
Main Methods:
- Review of preclinical studies on animal models.
- Analysis of structurally diverse melatonergic receptor agonists (indolic and nonindolic).
Main Results:
- Melatonin receptor agonists demonstrate potential in preclinical models.
- These agonists are being developed for various conditions, including sleep disturbances and CNS pathologies.
Conclusions:
- Investigational melatonergic drugs offer therapeutic potential beyond native melatonin.
- Selective agonists represent a promising avenue for treating circadian rhythm, neuropsychiatric, and metabolic disorders.

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...

01:19Management of Insomnia
765
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...

1.2K
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...

01:23Sedatives and Hypnotics: Overview
2.2K
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...

1.4K
Benzodiazepines have both sedative and hypnotic properties. They include compounds such as diazepam (Valium) and alprazolam (Xanax). Structurally, their cores are similar, consisting of the fusion of a benzene ring and a diazepine ring, but they share a common mechanism of action in the central nervous system (CNS).
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...

Antidepressant drugs are a class of medications primarily used for treating various mood disorders, including major depression, anxiety disorders, and other related conditions. These medicines work by modulating the neurotransmitter balance within the brain, alleviating depressive symptoms. Antidepressants can be broadly categorized into several groups according to their mechanism of action and chemical structure: Selective Serotonin Reuptake Inhibitors (SSRIs), Serotonin-Norepinephrine...
