Triampyzine (INN ), also known as triampyzine sulfate (USAN ; developmental code name W-3976B) in the case of the sulfate salt, as (dimethylamino)trimethylpyrazine, or as 3,5,6-trimethylampyzine, is a drug described as an anticholinergic and antisecretory agent which was never marketed. [1] [2] [3] [4] [5] It was first described in the literature by 1966. [1] [6] The drug is the 3,5,6-trimethylated derivative of ampyzine (W-3580B), which is also a drug and is, conversely, described as a "central stimulant". [1] [5] [2]
