The short answer is "I don't know"
I do know that I tend to have more faith in Merck or Eli Lilly or Pfizer than a small unkown company on the far side of the globe - Large major pharmaceutical firms have more to lose aka reputation and resources at risk - than a small easily bankrupted firm in Nowherestan with unavailable records or no records at all.
There are many German, English, French, and Japanese firms that are highly regarded, but much of the generic firms are less well known. Some are excellent, but as we found with the losartan, et al incident, some certainly are not. Generally Sandoz and Novartis are well regarded, but they apparently bought damaged merchandise to use in their final fabrication of drugs and didn't verify its safety before using it. They trusted the firms they bought from apparently.
I was in Sam's Wholesale recently and I needed some Aleeve - Na naproxen , cheap relatively safe at over the counter doses in most healthy folks - and a product of Bayer, a reputable German firm. I found two different sets of bottles for sale - one with a red top that was labeled Made in India, and one with a yellow top labeled made in China. No other information about the manufacturer could be found on the bottles. I could find no bottles labeled made in Germany or UK or USA. Which would you buy, or would you buy none? I KNOW that both countries have the ability to reliably manufacture very safe drugs - but at what price?
You can buy Na Naproxifen in large quantities on alibaba which I ran across the other day - but would you want to for human consumption? Without a lot more information at the very least.
I don't generally buy the very cheapest foods that I can find since I intend to eat them. Pharmaceutical chemicals are the same. The funny thing, of course, is that large numbers of folks buy elicit drugs without any idea of their provenance other than they bought it from their "dealer" who they apparently trust a great deal.
I think about this every time I shop for dog food too - remember the melamine contamination of dog food from China? Even dog food is sourced from many various spots around the world these days.,
Properly made pharmaceutical drugs should be able to show their provenance of agents used at each step in manufacture - that does cost significantly more, of course.
Do you believe your pharmacy benefits manager takes this in to account for its recommendations?
