ABSTRACT:
Improved anesthesia methods comprising pretreating a patient to be anesthetized with a benzopyran of formula I ##STR1## wherein, in the C ring, X is NR.sub.1, S, CH.sub.2 or ##STR2## R.sub.1 is hydrogen, loweralkyl, loweralkenyl, loweralkynyl, loweralkanoyl, cycloalkyloweralkyl, cycloalkylloweralkanoyl, cycloalkyl, haloloweralkyl, haloloweralkenyl, phenylloweralkyl, phenyloweralkenyl or phenyloweralkylnyl; m is an integer from 0 to 3, n is an integer from 0 to 3 and n + m = 2 or 3; or the C ring is quinuclidine ring ##STR3## R.sub.2 is loweralkyl; R.sub.3 is hydrogen or ##STR4## wherein Y is a straight or branched chain alkylene group having from one to eight carbon atoms, a is an integer from 1 to 4, b is an integer from 1 to 4, Z is CH.sub.2, O, S or NR.sub.6, R.sub.6 being hydrogen or loweralkyl, with the limitation that when Z is O, S or NR.sub.5, the sum of a and b is 3 or 4, and R.sub.5 is hydrogen or loweralkyl; R.sub.4 is C.sub.1 -C.sub.20 straight or branched chain alkyl, cycloalkyl, or ##STR5## wherein Y is a straight or branched chain alkylene group having from one to ten carbon atoms, and each R.sub.7, R.sub.8 and R.sub.9 are the same or different members of the group consisting of hydrogen, halo, trifluoromethyl or loweralkyl; and the pharmaceutically acceptable salts thereof, with the limitation that when X is ##STR6## m = 2 and n = 2, R.sub.3 cannot be hydrogen.
