It was 130C / 260F that is considerably higher than the inside of a car.
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 assume that's 140 Fahrenheit. The testing in question was conducted at 140 Celsius (which is quite a bit warmer...).
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.
The article is highly misleading. in the heating test, they heated the drug to 130 C, far beyond the temperature you'll find in a car. The gastric simulation with nitrites seems legit though.
