I can see people keeping some Zantac in their car and that gets quite hot (140+) in the summer.
I don’t think the penalty for not storing your medicine quite right should be ingesting a carcinogen.

Still, this suggests that ranitidine may not be stable and its breakdown products may be risky. If mixing it with nitrite produces NDMA under condition found in the stomach that is another risk case. I wonder if there is any breakdown over time just sitting on the shelf?
I also think it's unlikely that those people who are keeping their meds in their car are also keeping their meds dissolved in a solution with high levels of nitrite.
