Abstract

Novel 5-(3-alkyl-5-tert.butyl-4-hydroxyphenyl)-2-amino-6H-1,3,4-thiadiazines of the general formula I ##STR1## in which R.sup.1 =C.sub.1 -C.sub.4 -alkyl, PA0 R.sup.2 =H or C.sub.1 -C.sub.3 -alkyl PA0 R.sup.3 and R.sup.4 =independently of one another, optionally substituted and optionally O- or S-interrupted alkyl, alkenyl or alkynyl groups, it being possible for one of the two radicals to also be H, PA0 or R.sup.3 +R.sup.4 together with the nitrogen atom to which they are bound, may denote an optionally substituted 4- to 7-membered ring which optionally contains a further heteroatom (O, S or N), and the physiologically acceptable acid-addition salts thereof. The compounds are primarily suitable for prevention and treatment of inflammatory--in particular inflammatory rheumatic--disorders and/or pain.
