For the record, the original blog post gives the official position on Nitro meds. The What Can I Bring page gives a result that Nitro is allowed in checked and Carryon bags. Any time that is not followed, absent any indications that the medication has been altered to present a possible threat, is wrong. It has been stated here and at the Blog - repeatedly. If someone tells you that nitro meds are not allowed, they are wrong. Just like if this scenario played out like the OP says, and these items were not allowed into the sterile area in the absence of some alteration that presents a possible threat, would be wrong.
