Abstract
An analgesic composition comprising an analgesically effective amount of at least one 6,7-benzomorphan derivative of the formula: ##SPC1## Wherein R is a hydrogen atom, a hydroxyl group, a C.sup.1 - C.sup.3 alkoxy group or a C.sup.1 - C.sup.8 alkanoyloxy group; R.sub.1 is a hydrogen atom, a C.sup.1 - C.sup.5 alkyl group, a phenyl group, a halophenyl group, an alkylphenyl group wherein the alkyl moiety has 1 to 3 carbon atoms, an alkoxyphenyl group wherein the alkoxy moiety has 1 to 3 carbon atoms, a trifluoromethylphenyl group, an alkylthiophenyl group wherein the alkylthio moiety has 1 to 3 carbon atoms or a group of the formula (C.sub.m H.sub.2m.sub.-p.sub.+1) - (R.sub.9).sub.p wherein m is an integer of 1 - 6, p is an integer of 1 - 2 and R.sub.9 is a C.sup.1 - C.sup.3 alkoxy group; R.sub. 2 is a hydrogen atom or a C.sup.1 - C.sup.3 alkyl group; R.sub.3 is a hydrogen atom, a C.sup.1 - C.sup.3 alkyl group, a phenyl group or an alkoxyphenyl group wherein the alkoxy moiety has 1 to 3 carbon atoms; R.sub.4 is a hydrogen atom or a hydroxyl group, or R.sub.3 and R.sub.4 may form a C.sup.1 - C.sup.3 alkylidene group or a carbonyl group together with a carbon atom to which these substituents are bonded; R.sub.5 is a hydrogen atom or C.sup.1 - C.sup.3 alkyl group; R.sub.6 is a hydrogen atom or a methyl group; R.sub.7 and R.sub.8 are independently a hydrogen atom or a C.sup.1 - C.sup.2 alkyl group; and n is an integer of 0 - 2; or an acid addition salt thereof, and a pharmaceutically acceptable carrier or diluent, is disclosed.
