uf-021 and dorzolamide

Despite treatment, glaucoma patients may still suffer vision loss because of inadequate control of intraocular pressure or late presentation. This article reviews the latest evidence supporting a reappraisal of first-line treatment in the management of glaucoma, including a review of latanoprost, recently approved for first-line treatment of glaucoma and ocular hypertension.

To compare the efficacy and safety of timolol 0.5%/dorzolamide 2% fixed combination vs timolol maleate 0.5% and unoprostone 0.15% given twice daily.. Prospective multicenter, randomized, double-masked, crossover comparison study.. Primary open-angle glaucoma or ocular hypertension patients were randomly assigned to one of the treatment groups for a 6-week treatment period and then crossed over to the opposite treatment. Diurnal curve testing was performed at 8:00 AM, 10:00 AM, 4:00 PM, 6:00 PM, and 8:00 PM at baseline and the end of each treatment period. The run-in medicine was timolol twice daily for 28 days.. Thirty-two patients completed this trial. The baseline trough pressure was 24.3 +/- 3.0 mm Hg, and the diurnal curve was 23.4 +/- 3.2 mm Hg. For the fixed combination the treatment trough pressure was 20.8 +/- 4.1 mm Hg and the diurnal curve was 19.6 +/- 3.6 mm Hg, whereas timolol and unoprostone concomitant therapy showed a treatment trough pressure of 20.1 +/- 4.5 mm Hg and a diurnal pressure of 19.8 +/- 4.1 mm Hg. There was no significant difference between treatment groups at any time point, for the diurnal curve, or in the extended reduction from baseline. There was no difference between treatment groups regarding ocular and systemic unsolicited or solicited adverse events. Burning, stinging, and conjunctival hyperemia were the adverse events most noted. There were no serious adverse events during this trial.. This study suggests that both timolol/dorzolamide 2% fixed combination and concomitant timolol maleate 0.5% and unoprostone 0.15% therapy provide similar efficacy and safety throughout the daytime diurnal curve.

To compare the safety and efficacy of unoprostone, brimonidine, and dorzolamide as adjunctive therapy to timolol in patients with primary open angle glaucoma or ocular hypertension.. This was a randomised, double masked, parallel group, multicentre (14) study. After using timolol maleate 0.5% monotherapy twice a day for 2 weeks, patients (n = 146) with an early morning intraocular pressure (IOP) between 22 and 28 mm Hg, inclusively, received unoprostone isopropyl 0.15% (n = 50), brimonidine tartrate 0.2% (n = 48), or dorzolamide hydrochloride 2.0% (n = 48) twice daily as adjunctive therapy to timolol maleate 0.5% for another 12 weeks. Safety was based on comprehensive ophthalmic examinations, adverse events, and vital signs. Efficacy was based on mean change from baseline in the 8 hour diurnal IOP at week 12. Baseline was defined as values obtained after 2 weeks of timolol monotherapy.. Each drug was safe and well tolerated. Burning/stinging was the most common treatment emergent adverse event. No clinically relevant changes from baseline were observed for any ophthalmic examination or vital signs. At week 12, each adjunctive therapy produced statistically significant (p<0.001) reductions from timolol treated baseline in the mean 8 hour diurnal IOP (-2.7 mm Hg, unoprostone; -2.8 mm Hg, brimonidine; -3.1 mm Hg, dorzolamide). The extent of IOP reduction did not differ significantly between unoprostone and either brimonidine (p = 0.154) or dorzolamide (p = 0.101).. Unoprostone was safe and well tolerated and provided a clinically and statistically significant additional reduction in IOP when added to stable monotherapy with timolol. Furthermore, unoprostone was not significantly different from brimonidine and dorzolamide as adjunctive therapy to timolol.

To investigate the clinical characteristics of docosanoid derivative, isopropyl unoprostone in the treatment of primary open angle glaucoma (POAG).. In 17 patients (22 eyes) with POAG we analysed prospectively the effect of Rescula upon intraocular pressure, aqueous flare, pupil size, ocular signs and symptoms. Patients were followed up every 2 weeks for at least 8 weeks with complete ocular examination. Concomitant topical therapeutics were used in the study: 0.5% Timolol--group I (16 eyes), and 0.5% Timolol + 2% Dorzolamide--group II (6 eyes).. Mean (+/- SD) pretreatment pressure was 24.7 +/- 4.3 mm Hg in group I and it was reduced by 3.7 mm Hg (13.5%) (p < 0.05) at the end of the follow up. In group I Rescula was very effective (delta T% > 25%) in 6/16 eyes (37.5%) and it was ineffective (delta T% < 10%) in the same number of eyes. In group II pretreatment pressure was 24.8 +/- 2.6 mm Hg and it was reduced by 2.6 mm Hg (10.6%) (p = 0.1). Rescula induced no elevation of the aqueous flare during the treatment. No effect on pupil size was observed, either. Eye stinging/conjunctival hyperaemia was noted in 2/17 patients and punctate epitheliopathy in 1 patient (5.9%) that caused discontinuation of drops.. Unoprostone produced significant additive effect to Timolol. Thus, it may be a valuable option for adjunctive therapy. However, interindividual differences need to be considered, as in some patients the response was insignificant.

To evaluate the ocular factors contributing to keratoepitheliopathy in glaucoma patients treated with or without anti-glaucomatous eyedrops, and the influences of each anti-glaucomatous eyedrop to keratoepitheliopathy.. The presence and severity of keratoepitheliopathy was investigated in 193 eyes of 110 glaucoma patients. The ocular factors examined were the status of the lipid layer of the tear fluid as assessed by a specular reflection video-recording system, tear volume assessed by Schirmer's test, and tear film stability assessed by tear break-up time. The influences of combined anti-glaucomatous eyedrops and each anti-glaucomatous eyedrops to keratoepitheliopathy were investigated.. The overall occurrence of superficial punctate keratitis was 29.0%. Superficial punctate keratitis was more frequently observed in patients who used more than two anti-glaucomatous eyedrops (35.9%) than in those who used without (19.7%) and one (30.9%). Results of Schirmer's test and break-up time were worse in patients who used combined medication. The occurrence of superficial punctate keratitis in patients who used timolol (46.2%) was significantly more frequent than in those who used carteolol (4.2%). Severity of superficial punctate keratitis and break-up time in patients who used timolol were significantly worse than in those who used carteolol. There were no differences of keratoepitheliopathy and ocular factors between patients who used latanoprost and unoprostone.. The usage of multiple anti-glaucomatous eyedrops induces keratoepitheliopathy by reducing the tear volume and the tear film stability. Carteolol may be used more safely for corneal epithelium.
