ABSTRACT:
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.
