As of my last knowledge update in January 2022. I don’t have specific information about a compound or substance named “NDTDI” in the context of ergoline. It’s possible that NDTDI is a term or abbreviation specific to a particular field or industry. And it might not be widely recognized or documented in the available information up to that point.

“Ergoline” generally refers to a chemical class of alkaloid compounds that contain a core structure based on ergotamine. Ergoline derivatives have been studied for their various pharmacological effects. Including interactions with serotonin and dopamine receptors.

If NDTDI is a compound or term that has emerged or gained significance after my last update. I recommend checking the latest scientific literature. Medical databases. Or consulting with a chemist, pharmacologist, or healthcare professional for the most current and accurate information.

If you have additional details or context about NDTDI that you’d like me to consider. Please provide more information. And I’ll do my best to assist you based on the information available up to my last update.
