I've replaced the deadlink with a ref from Univ. of Maryland. --Hordaland (talk) 02:29, 27 January 2016 (UTC)[reply]

Availability in Eastern Europe

Although I cannot quote any reliable sources, Melatonin tablets are freely sold across most of Eastern Europe. There is also an sublingual composition marketed as Somni-X. It is a fast onset spray, applied under the tongue. --lasombra bg (talk) 21:45, 16 September 2016 (UTC)[reply]

Melatonin should be described as a neurotransmitter

That Melatonin acts as a neurotransmitter is implicit on this page in that it's part of the "neurotransmitters" series, and also that the *effects* of Melatonin receptors being engaged is described in the "Functions" section, however it is never clearly stated. See: Serotonin page functions section. --Whilom Chime (talk) 17:09, 4 December 2016 (UTC)[reply]

It is actually a hormone, not a neurotransmitter that has effects on more distant cells, not just adjacent cells connected by synapses. I have edited the lead so that it now stated that it is a hormone in the lead sentence. Boghog (talk) 18:54, 4 December 2016 (UTC)[reply]

Apologies, I certainly didn't mean to imply that it isn't a hormone, but that like norepinephrine it is both. I'm definitely not an expert, but I'm assuming its activity with Melatonin receptors in the suprachiasmatic nuclei of the hypothalamus means that it is also a neurotransmitter. I'm quite willing to be educated that it is not, but if that's the case it should be removed from the neurotransmitter page and the neurotransmitter list.--Whilom Chime (talk) 20:14, 4 December 2016 (UTC)[reply]

No problem. I am not an expert either. The sources that I have read invariably describe melatonin as a (neuro)hormone that is synthesized in the pineal gland. For melatonin to be classified as a neurotransmitter, it would also need to be released from presynaptic neurons and I can find no support for that in the literature. Hence as you suggest, I think melatonin should be removed from the {{Neurotransmitters}} navbox and neurotransmitter article. Boghog (talk) 06:12, 5 December 2016 (UTC)[reply]

Review article saying that melatonin is effective for treating primary insomnia

Here's the article: https://www.ncbi.nlm.nih.gov/pubmed/28648359 I don't want to edit the part of the article which says that there's not enough evidence for this myself owing to my very limited knowledge of such subjects, but perhaps that should be done if that review article is right.

medical uses and side effects categories overlap

There are quite a few side effects listed under medical uses. Perhaps these categories should simoly be combined into "Medical uses and side effects". Dig _deeper ^talk 04:11, 1 March 2018 (UTC)[reply]
