Is Melatonin Anticholinergic? Exploring the Effects and Safety of Melatonin

Melatonin is a hormone naturally produced by the pineal gland in the brain. It plays a crucial role in regulating the sleep-wake cycle and is often used as a sleep aid. However, there have been concerns about the potential anticholinergic effects of melatonin.

What are Anticholinergic Effects?

Anticholinergic effects refer to the inhibition of the neurotransmitter acetylcholine in the central and peripheral nervous systems. These effects can impact various bodily functions, including cognition, memory, and muscle control.

The Relationship Between Melatonin and Anticholinergic Effects

While melatonin is not classified as an anticholinergic drug, some studies suggest that it may have mild anticholinergic properties. However, the extent and clinical significance of these effects are still under investigation.

Studies on Melatonin's Anticholinergic Effects

A study published in the Journal of Clinical Psychopharmacology found that melatonin administration in healthy volunteers resulted in minor cognitive impairments, potentially indicating anticholinergic activity.
Another study published in the Journal of Clinical Psychopharmacology examined the effects of melatonin on cognitive function in elderly individuals. The results showed no significant cognitive impairments.
