This invention provides methods for the treatment or prevention of sleep apnea in a mammal which comprise administering to a mammal in need thereof an effective amount of a compound of formula (I) where R.sup.1 and R.sup.2 are independently selected from the group consisting of hydrogen, methyl, methoxy, chloro, and trifluoromethyl, with the proviso that no more than one of R.sup.1 and R.sup.2 can be hydrogen; and Y is (a), (b), (c), (d), (e), (f), N-R.sup.a, or CH-NR.sup.b R.sub.c, where R.sup.a, R.sup.b, and R.sup.c are independently selected from the group consisting of hydrogen and C.sub.1 -C.sub.6 alkyl; or a pharmaceutically acceptable salt or solvate thereof.
本发明提供了用于哺乳动物的睡眠呼吸暂停的治疗或预防方法,包括向需要该治疗的哺乳动物施用式(I)化合物的有效量,其中R.sup.1和R.sup.2分别选择自氢、甲基、甲氧基、
氯或三
氟甲基的群组,但R.sup.1和R.sup.2中最多只能有一个为氢;而Y是(a)、(b)、(c)、(d)、(e)、(f)、N-R.sup.a或CH-NR.sup.b R.sub.c,其中R.sup.a、R.sup.b和R.sup.c分别选择自氢和C.sub.1-C.sub.6烷基的群组;或其药学上可接受的盐或溶剂。
