Claim 1
Independent Claim
122 words
A .Iadd.pharmaceutical composition having analgesic and muscle relaxant activity, in dosage unit form, comprising a solid pharmaceutical carrier and from about 25 mg. to about 350 mg. of a .Iaddend.chemical compound of the class consisting of a free base and its nontoxic, pharmaceutically acceptable acid addition salts, the free base having the formula: ##SPC6## in which: R is a member selected from the group consisting of halogen having an atomic weight of less than 80 and trifluoromethyl, said member being in a position β to the hetero ring; R 1 is a member selected from the group consisting of hydrogen, lower alkyl and phenyl; and R 2 and R 3 are members selected from the group consisting of hydrogen and lower alkyl.
