New thiatriazine derivatives of the general formula
are described as well as a process for their manufacture. The new compounds exhibit histamine H-2 antagonist activity and may be used to inhibit gastric acid secretion and to treat gastric and peptic ulcers.
Salts of 3-amino-5-[2-[ (2-guanidino-4-thiazolyl) -methylthio] ethylamino] -4-methyl-1,2,4,6-thiatriazine-1, 1-dioxide with various acids are prepared in crystalline form. The salts contain varying amounts of crystal water or crystal solvent.
