The invention relates to the use of derivatives of F-type prostaglandins as ocular hypotensives. The PGF derivatives used in accordance with the invention are represented by the following formula I:
1
wherein wavy line attachments indicate either the alpha (&agr;) or beta (&bgr;) configuration; dashed bonds represent a double bond, or a single bond, R is a substituted heteroaryl radical, R
1
is hydrogen or a lower alkyl radical having up to six carbon atoms, X is selected from the group consisting of —OR
1
, —N(R
1
)
2
, R
1
is hydrogen or a lower alkyl radical having up to six carbon atoms, X is selected from the group consisting of —OR
1
, —N(R
1
)
2
and —N(R
5
)SO
2
R
6
, wherein R
5
represents hydrogen or CH
2
OR
6
and R
6
represents hydrogen or a lower alkyl radical having up to six carbon atoms and halogen substituted derivatives of said lower alkyl radical, e.g. a fluoro substituted lower alkyl radical; Y is ═O or represents 2 hydrogen radicals. Certain of the compounds represented by Formula I comprise another aspect of the present invention.
