Description

Piromelatine is an investigational therapy being developed by Neurim Pharmaceuticals to manage sleeping difficulties. The compound is now being studied for its potential to improve cognitive function and slow the progression of Alzheimer’s disease by promoting better sleep. It acts primarily as an agonist of MT1/MT2/MT3 melatonin receptors and serotonin 5-HT1A and 5-HT1D receptors, but reportedly also is a low-affinity antagonist of 5-HT2B, P2X3, and TRPV1 receptors. Piromelatine may benefit control of circadian rhythm, metabolism, cognition and mood. Preclinical studies have reported cognitive improvement in rats that received hippocampal Aβ42 injections to simulate Alzheimer’s disease. There are also reports on painkilling and hypnotic effects in a mouse model of neuropathic pain, as well as blood pressure lowering in rats. Piromelatine is in phase II clinical trial for the treatment of Alzheimer's disease, Insomnia, Ocular hypertension and Open-angle glaucoma.
