There are a few other drugs that have had NMDA in them. I’m not sure this is something specific to Indian drug makers.

I don’t know but last year there was a widespread shortage of the angiotensin receptor blocker (ARB) drugs used for high blood pressure. The shortage was caused by contamination problems in the Indian manufacturing locations to which much production was moved by the pharmaceutical industry. That affected me and my doctor had to move me to a different drug. The common factor to these contamination problems was Indian (and some Chinese) manufacturing facilities.
