What are some novel or emerging uses and areas of research for atropine beyond its classical applications?

I'm interested in pharmacological repurposing. Beyond its use in bradycardia, anesthesia, and ophthalmology, is atropine being studied for novel indications like myopia control, neurodegenerative diseases, or as an adjunct in cancer therapy? What does the latest preclinical or clinical research suggest?

The most impactful novel use is low-dose atropine (0.01%) for slowing childhood myopia progression, now a well-supported clinical protocol. Beyond this, exciting research frontiers include its potential neuroprotective effects in conditions like Parkinson's disease, mediated through modulation of neuroinflammation. Preclinical studies are investigating its role as an adjunct in cancer therapy to mitigate certain side effects or influence tumor microenvironments. I've also seen research into its use for sialorrhea (excessive drooling) in neurological disorders. These avenues exploit atropine's antimuscarinic properties in new physiological contexts, demonstrating how classic agents can find renewed life through targeted, low-dose applications.
