Ocular effects of two different prostaglandin F2 alpha esters. A doublemasked cross-over study on normotensive eyes.

Ocular hypotensive effects and side effects of two different topically applied prostaglandin (PG) esters were evaluated in a double masked study in 12 healthy males. Three doses of 15-propionat-PGF2 alpha-isopropylester (15-prop-PGF2 alpha-IE), two doses of PGF2 alpha-isopropylester (PGF2 alpha-IE), and placebo were compared. At equipotent doses 15-prop-PGF2 alpha-IE caused similar ocular side effects as PGF2 alpha-IE. It is concluded that both PGF2 alpha-IE and 15-prop-PGF2 alpha-IE reduce the IOP in normal eyes, but the use of a diester such as 15-prop-PGF2 alpha-IE does not provide a better separation between effect on IOP and side effects than PGF2 alpha-IE.
