A pharmaceutical composition, preferably ophthalmic solution or ophthalmic suspension, useful for treating animals of the mammalian species, including humans, to reduce or maintain intraocular pressure in the eye contains as its pharmacologically active ingredient one or more compounds of the formula ##STR1## where X is O, 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 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,首选为眼科溶液或眼科悬浮液,用于治疗哺乳动物物种,包括人类,以减少或维持眼内压力,其药理活性成分为公式##STR1## 中的一种或多种化合物,其中X为O,S或NH;n为0、1或2的整数;当n为0时,R.sub.1为1至6个碳原子的低碳基,R.sub.2为H或1至6个碳原子的低碳基;当n为1或2时,R.sub.1和R.sub.2为亚甲基(CH.sub.2),或亚甲基上取代有R.sub.5基团的亚甲基,其中R.sub.5为1至6个碳原子的低碳基;R.sub.3和R.sub.4独立地为H或1至6个碳原子的低碳基;R.sub.6为H或1至6个碳原子的低碳基。
