Why does the Wiki recommend this? Is it correct?

[Yagami]

"While the PPH still incorrectly recommends using H2 receptor antagonists, such as cimetidine and ranitidine, simply not using them will result in a more peaceful death, owing to formation of nitric oxide, a vasodilator..."

Regarding SN method

 

[Wrennie]

This is interesting. Mind if I ask where you got this information from? I thought that the usage of H2 Receptor Antagonists were supposed to prevent the conversion of Nitrite into NitrAte by the stomach after ingestion.

Edit: Title mentions wiki as source. Still curious to know how they reached that conclusion.
