From the USDA's website:

"It is assumed that it is considered a general antibiotic."

I said the same thing when I saw the comment in the article, then I figured I'd go looking.

LOL! You beat me to it!

Tennessee,

Read it again, in context. I think they were talking about a regulatory classification, as relates to vetrinary use. Could even be a misprint. Either way it makes no sense. (Sorry, I haven't the means to cut and paste a PDF file)

The same document you quoted notes in more than one place that atropine is an "AntiCHOLINERGIC" (emphasis mine).

Atropine is indeed an anticholinergic drug, and is in fact related to belladonna, which is used in eye drops to dialate the pupil. It can also be inhaled as a bronchodialator.

I am not a Dr, nor do I play one on TV. From everything I read, including the source you provided, it sure doesn't look to me that atropine is an antibiotic. Perhaps there is a pharmacist lurking about who can provide a final say?

Cheers!

Nik
