Dose response of topical pilocarpine-epinephrine combinations in normotensive and glaucomatous Beagles.
Dose responses to single-dose loadings with a placebo (0.50% methylcellulose) and 1%, 2%, 3%, 4%, and 6% pilocarpine combined with 1% epinephrine were determined in normotensive and glaucomatous Beagle dogs. All combinations of pilocarpine and 1% epinephrine significantly (P less than 0.007) reduced pupil size and intraocular pressure in the normotensive and glaucomatous-treated eyes at most measurement times, as compared with base-line (predrug) values, untreated fellow eyes, and placebo-treated eyes. There were no significant (P less than 0.11 or greater) contralateral effects on pupil size and intraocular pressure by unilateral pilocarpine-epinephrine instillations as compared with base-line values or placebo-treated eyes.
