"Jan. 4, 2013 -- A new study from Australia may offer a new way of identifying people at risk of glaucoma years before vision loss happens.
Glaucoma is a leading cause of blindness. But because vision damage often occurs gradually, mos"...
PROPINE® (dipivefrin HCI ophthalmic solution, USP) is indicated as initial therapy for the control of intraocular pressure in chronic open-angle glaucoma. Patients responding inadequately to other antiglaucoma therapy may respond to addition of PROPINE® (dipivefrin) .
In controlled and open-label studies of glaucoma, PROPINE® (dipivefrin) ophthalmic solution demonstrated a statistically significant intraocular pressure-lowering effect. Patients using PROPINE® (dipivefrin) twice daily in studies with mean durations of 76-146 days experienced mean pressure reductions ranging from 20-24%.
Therapeutic response to PROPINE® (dipivefrin) ophthalmic solution twice daily is somewhat less than 2% epinephrine twice daily. Controlled studies showed statistically significant differences in lowering of intraocular pressure between PROPINE® (dipivefrin) and 2% epinephrine. In controlled studies in patients with a history of epinephrine intolerance, only 3% of patients treated with PROPINE® (dipivefrin) ophthalmic solution exhibited intolerance, while 55% of those treated with epinephrine again developed intolerance.
Therapeutic response to PROPINE® (dipivefrin) twice daily therapy is comparable to 2% pilocarpine 4 times daily. In controlled clinical studies comparing PROPINE® (dipivefrin) ophthalmic solution and 2% pilocarpine, there were no statistically significant differences in the maintenance of IOP levels for the two medications. PROPINE® (dipivefrin) does not produce miosis or accommodative spasm which cholinergic agents are known to produce. Night blindness often associated with miotic agents is not present with PROPINE® (dipivefrin) therapy. Patients with cataracts avoid the inability to see around lenticular opacities caused by constricted pupil.
DOSAGE AND ADMINISTRATION
Initial Glaucoma Therapy
The usual dosage of PROPINE® (dipivefrin) is one drop in the eye(s) every 12 hours.
Replacement with PROPINE® (dipivefrin) ophthalmic solution
When patients are being transferred to PROPINE® (dipivefrin) from antiglaucoma agents other than epinephrine, on the first day continue the previous medication and add one drop of PROPINE® (dipivefrin) ophthalmic solution in each eye every 12 hours. On the following day, discontinue the previously used antiglaucoma agent and continue with PROPINE® (dipivefrin) .
In transferring patients from conventional epinephrine therapy to PROPINE® (dipivefrin) ophthalmic solution, simply discontinue the epinephrine medication and institute the PROPINE® (dipivefrin) regimen.
Addition of PROPINE® (dipivefrin) ophthalmic solution
When patients on other antiglaucoma agents require additional therapy, add one drop of PROPINE® (dipivefrin) every 12 hours.
For difficult to control patients, the addition of PROPINE® (dipivefrin) ophthalmic solution to other agents such as pilocarpine, carbachol, echothiophate iodide or acetazolamide has been shown to be effective.
