A method of achieving a muscle-relaxing effect in a patient comprises administering to a patient in which a muscle relaxing effect is desired an amount effective to achieve a muscle-relaxing effect of a compound of the formula ##STR1## wherein R is H, or C.sub.1-7 straight or branched chain alkyl; R.sub.1 is H, C.sub.1-7 straight or branched chain alkyl, allyl or phenyl; R.sub.2 is phenyl, phenyl monosubstituted with F, Cl, C.sub.1-4 straight or branched chain alkyl or phenyl disubstituted in the 2- and 4-positions with Cl or C.sub.1-4 straight or branched chain alkyl; and R.sub.3 is H or C.sub.1-4 straight or branched chain alkyl, with the proviso that when R.sub.3 is straight or branched chain alkyl, R.sub.2 is unsubstituted phenyl; or a pharmaceutically acceptable acid addition salt thereof.
在患者中实现肌肉松弛效果的方法包括向需要肌肉松弛效果的患者施用一定量的化合物,以实现肌肉松弛效果,该化合物的结构式为##STR1##其中R为H,或C.sub.1-7直链或支链烷基;R.sub.1为H,C.sub.1-7直链或支链烷基,烯丙基或苯基;R.sub.2为苯基,苯基单取代为F、Cl、C.sub.1-4直链或支链烷基或苯基二取代在2-和4-位为Cl或C.sub.1-4直链或支链烷基;以及R.sub.3为H或C.sub.1-4直链或支链烷基,但当R.sub.3为直链或支链烷基时,R.sub.2为未取代的苯基;或其药学上可接受的酸盐。
