What is the recommended expiration of sublingual nitroglycerin after opening? I was told the bottle should be discarded after every use which I have never heard of before. I have only seen discard 6mo after opening at the earliest and have also read that with new formulations nitro is stable for the entire expiration date after opening?
Does anyone have any sources to support either positions?
