A pharmaceutical composition, useful for treating animals of the mammalian species, including humans, to treat diseases and conditions which normally respond to treatment with alpha.sub.2 adrenergic agents, contains as its active alpha.sub.2 adrenergic agent ingredient one or more compounds of the formula ##STR1## where X is 0, S or NH; n is an integer with the values of 0, 1 or 2; when n is 0 then R.sub.1 is lower alkyl having 1 to 6 carbon atoms and R.sub.2 is H or lower alkyl having 1 to 6 carbon atoms; when n is 1 or 2, then R.sub.1 and R.sub.2 both are methylene (CH.sub.2), or methylene substituted with an R.sub.5 group where R.sub.5 is lower alkyl of 1 to 6 carbons; R.sub.3 and R.sub.4 independently are H or lower alkyl having 1 to 6 carbons; R.sub.6 is H or lower alkyl of 1 to 6 carbons.
一种制药组合物,用于治疗哺乳动物,包括人类,以治疗通常对α.sub.2肾上腺素能受体激动剂治疗有反应的疾病和症状,其活性α.sub.2肾上腺素能受体激动剂成分为下列化合物之一或多个:其中X为0、S或NH;n是一个整数,取值为0、1或2;当n为0时,R.sub.1为具有1至6个碳原子的低碳烷基,R.sub.2为H或具有1至6个碳原子的低碳烷基;当n为1或2时,R.sub.1和R.sub.2均为亚甲基(CH.sub.2),或者亚甲基上取代有一个R.sub.5基团,其中R.sub.5为1至6个碳原子的低碳烷基;R.sub.3和R.sub.4独立地为H或具有1至6个碳原子的低碳烷基;R.sub.6为H或具有1至6个碳原子的低碳烷基。
