Triampyzine
Triampyzine, also known as triampyzine sulfate in the case of the sulfate salt, as trimethylpyrazine, or as 3,5,6-trimethylampyzine, is a drug described as an anticholinergic and antisecretory agent which was never marketed. It was first described in the literature by 1966. The drug is the 3,5,6-trimethylated derivative of ampyzine, which is also a drug and is, conversely, described as a "central stimulant".
