Pain control by melatonin: Physiological and pharmacological effects

Area of Science:

• Neuroscience
• Pharmacology
• Endocrinology

Background:

• Pain and anxiety are common neurological responses with challenging clinical management.
• Conventional analgesics like morphine, NSAIDs, and acetaminophen have significant side effects.
• Melatonin, a pineal hormone, regulates circadian rhythms and possesses diverse pharmacological actions.

Purpose of the Study:

• To review the analgesic and anxiolytic potential of melatonin.
• To explore the mechanisms underlying melatonin's effects on pain and anxiety.
• To assess the clinical applicability of melatonin as an alternative therapeutic agent.

Main Methods:

• Review of scientific literature on melatonin's effects in pain and anxiety.
• Analysis of melatonin's receptor interactions (MT1/MT2, RZR/ROR).
• Examination of pathways involved in melatonin's analgesic action (e.g., endorphins, GABA, opioids, nitric oxide).

Main Results:

• Melatonin's effectiveness as an analgesic and anxiolytic agent demonstrated in animal models.
• Clinical studies indicate melatonin's efficacy in various pathological conditions and post-surgery.
• Melatonin acts via MT1/MT2 membrane and RZR/ROR nuclear receptors.

Conclusions:

• Melatonin exhibits significant analgesic and anxiolytic properties.
• Its ability to manage pain and anxiety offers a potential alternative to existing treatments.
• Melatonin's clinical application is supported by preclinical and clinical evidence.
