Comparison of travoprost 0.0015% and 0.004% with timolol 0.5% in patients with elevated intraocular pressure: a 6-month, masked, multicenter trial

OBJECTIVE: To compare the safety and intraocular pressure (IOP)-lowering efficacy of once-daily travoprost (0.0015% and 0.004%) to twice-daily timolol 0.5%. DESIGN: Prospective, 6-month, randomized, controlled, multicenter, double-masked, phase III study. PARTICIPANTS: Six hundred five patients with open-angle glaucoma or ocular hypertension. METHODS: Patients with an 8 AM IOP between 24 to 36 mmHg in at least one eye (the same eye) at two eligibility visits received either travoprost 0.0015%, travoprost 0.004% (dosed every day), or timolol 0.5% (dosed twice daily). MAIN OUTCOME MEASURES: Mean IOP at 8 AM, 10 AM, and 4 PM in the patient's eye with the higher baseline IOP. RESULTS: The mean IOP was significantly lower for both concentrations of travoprost compared with timolol. Travoprost was statistically superior to timolol at 9 of 13 visits, with differences in IOP reductions ranging from 0.9 to 1.8 mmHg (0.0015%) and 10 of 13 visits with differences in IOP reductions from 0.9 to 2.4 mmHg (0.004%). Mean IOP changes from baseline ranged from -6.0 to -7.5 mmHg (0.0015%), -6.5 to -8.0 mmHg (0.004%), and -5.2 to -7.0 mmHg for timolol. Hyperemia was experienced at rates of 29.2% (59 of 202) for travoprost 0.0015%, 42.8% (86 of 201) for travoprost 0.004%, and 8.9% (18 of 202) for timolol. Iris pigmentation changes were observed in 1.0% (2 of 200) of patients receiving travoprost 0.004% with no changes noted in the travoprost 0.0015% group or the timolol group. A decrease in pulse and systolic blood pressure was observed in the timolol group. There were no other clinically relevant or statistically significant changes from baseline in ocular signs or laboratory values, and no serious, related, unexpected adverse events were reported for any group. CONCLUSIONS: Travoprost (0.0015% and 0.004%), dosed once daily in the evening, is statistically superior or equal to timolol 0.5% dosed twice daily at all treatment visits during this 6-month study. IOP reductions of up to 2.0 mmHg greater than timolol were found in the travoprost 0.004% pooled data group. Travoprost is safe and well tolerated in patients with open-angle glaucoma or ocular hypertension.     

Efficacy and safety of a fixed combination of travoprost 0.004%/timolol 0.5% ophthalmic solution once daily for open-angle glaucoma or ocular hypertension

PURPOSE: To compare the efficacy of a fixed combination of travoprost 0.004%/timolol 0.5% every day in the morning with a concomitant regimen of timolol 0.5% every day in the morning, plus travoprost 0.004% every day in the evening; and timolol 0.5% twice daily on the intraocular pressure (IOP) of subjects with open-angle glaucoma or ocular hypertension over 3 months. DESIGN: Prospective, randomized, double-masked, parallel-group, active-controlled, multicenter trial. METHODS: Patients comprised adult subjects (n = 403) of either gender with open-angle glaucoma or ocular hypertension in at least one eye. To qualify, the IOP had to be between 22 to 36 mm Hg in the same eye at two consecutive eligibility visits. The primary outcome variable was IOP measured with a Goldmann applanation tonometer. RESULTS: Mean IOP ranged from 16.2 to 17.4 mm Hg with the combination travoprost/timolol compared with 15.4 to 16.8 mm Hg in the concomitant travoprost + timolol group, from baselines of 23.1 to 25.6 mm Hg and 22.9 to 25.0 mm Hg, respectively. The fixed combination of travoprost/timolol significantly lowered IOP by 7 to 9 mm, similar to the IOP reductions observed with concomitant therapy. The most frequent ocular adverse event was hyperemia that occurred in 14.3% and 23.4% of subjects treated with travoprost/timolol combination and concomitant travoprost + timolol, respectively. CONCLUSIONS: Travoprost/timolol combination produces greater IOP reductions than the positive control, timolol 0.5%, and reductions that were similar to concomitant travoprost + timolol. This study demonstrates that the fixed combination of travoprost/timolol produces significant and clinically relevant reductions of IOP in a once-daily dosing regimen.     

A three-month, multicenter, double-masked study of the safety and efficacy of travoprost 0.004%/timolol 0.5% ophthalmic solution compared to travoprost 0.004% ophthalmic solution and timolol 0.5% dosed concomitantly in subjects with open angle glaucoma or ocular hypertension

PURPOSE: The primary objective of this study was to compare the intraocular pressure (IOP)-lowering efficacy of travoprost 0.004%/timolol 0.5% fixed combination to the concomitant administration of travoprost 0.004% (TRAVATAN) and timolol 0.5% in subjects with open angle glaucoma or ocular hypertension. METHODS: This was a randomized, multicenter, double-masked, active-controlled, parallel group study. Three hundred sixteen patients with open angle glaucoma or ocular hypertension were randomly assigned to travoprost 0.004%/timolol 0.5% ophthalmic solution fixed combination once daily in the morning or concomitant administration of timolol 0.5% once daily in the morning and travoprost 0.004% ophthalmic solution once daily in the evening. The efficacy and safety of the fixed combination were compared with concomitant therapy over three months. The primary efficacy outcome measure was mean intraocular pressure. RESULTS: Both travoprost 0.004%/timolol 0.5% fixed combination and the concomitant administration of travoprost 0.004% and timolol 0.5% produced statistically significant reductions from baseline in IOP, with mean IOP ranging from 15.2 to 16.5 mm Hg in the patients using travoprost 0.004%/timolol 0.5% fixed combination compared with 14.7 to 16.1 mm Hg in the concomitant group. The upper 95.1% confidence limit for the differences in mean IOP (fixed combination minus concomitant) was < or =1.5 mm Hg at 7 of 9 visits, including all three 8 AM time points, 24-hours post-dose. Mean IOP reductions from baseline ranged from 7.4 to 9.4 mm Hg in the fixed combination group compared with 8.4 to 9.4 mm Hg with concomitant therapy. Safety analysis demonstrated equivalent safety between the two treatment groups. CONCLUSIONS: A fixed combination of travoprost 0.004% and timolol 0.5% produced clinically relevant IOP reductions in patients with open angle glaucoma or ocular hypertension that were comparable to concomitant therapy with its components. Safety and tolerability of the fixed combination were also equivalent to concomitant therapy. Travoprost 0.004%/timolol 0.5% fixed combination offers IOP reduction equivalent to concomitant therapy, with potential benefits that include convenience (fewer bottles and drops per day), improved compliance, cost savings (based on fewer co-payments), and elimination of potential washout effects.     

Different Effects of Topical Prazosin and Pilocarpine on Uveoscleral Outflow in Rabbit Eyes

Purpose:To investigate the effects of topical prazosin and pilocarpine on uveoscleral outflow(Fu) in rabbits.Methods:Sixteen rabbits were randomly divided into the control group (5 rabbits, only topical application of normal saline in the fight eye of each rabbit), Prazosin (PZ) treated group (6 rabbits, only 0.1％ Prazosin eyedrop 0.1％ in the right eye of each one) and Pilocarpine (PC) treated group (5 rabbits, 1％ Pilocarpine eye drop in each fight eye). Intraocular pressure (IOP) of bilateral eyes of each rabbit was measured before and 1h after topical application of the eye drop. And the bilateral eyes were perfused with Fluorescein-isothiocyanate bovine serum albumin (FITC-BSA) as the tracer into the anterior chamber of each rabbit for 30 min at 90 min after topical treatment. Then the rabbits were killed for Fu measurement.Results:IOP of PZ-treated eyes decreased [(0.71±0.07)kPa] in 1 hour after PZ application. IOP of PC-treated eyes decreased [(0.70±0.08)kPa] in 1 hour after PC application. Th     

Additivity of pilocarpine to bimatoprost in ocular hypertension and early glaucoma

PURPOSE: To determine if the intraocular pressure (IOP) effect of pilocarpine at various concentrations is additive to that of bimatoprost and to assess the tolerability of this combination. METHODS: This was a randomized, prospective trial of patients with IOP > 21 mm Hg following appropriate medication washout. For all visits IOP was measured at 9:00 AM and 11:00 AM. Following baseline visit (#1), bimatoprost 0.03% was instilled qhs OU through visit 6. Following visits 2, 3, and 4 pilocarpine (2%, 4%, 6%) was instilled qid in one randomly selected eye. Pilocarpine was discontinued after visit 5 and bimatoprost after visit 6. Two-tailed, paired t test was used to compare treated and contralateral eyes for their IOP, IOP change, percentage IOP change from baseline, and to compare IOP in the same eye at 9:00 AM and 11:00 AM (before and after pilocarpine administration). IOPs using bimatoprost alone or in combination with various pilocarpine concentrations were compared using single variant Analysis of Variance (ANOVA). RESULTS: Seventeen patients were enrolled and 13 patients completed the study. Bimatoprost reduced IOP 28.7% to 30.5% (P < 0.0001) from baseline to visit 2. IOPs in eyes treated with bimatoprost alone or with bimatoprost and various pilocarpine concentrations were similar (P > 0.81, ANOVA). The IOP (P > 0.17) and percentage IOP change from baseline (P > 0.10) was similar in treated and contralateral eyes with all three strengths of pilocarpine. IOP values at 9:00 AM and 11:00 AM, before and after pilocarpine administration, were similar (P > 0.22). CONCLUSION: Bimatoprost alone reduces IOP substantially. Pilocarpine added to bimatoprost at concentrations of 2%, 4%, or 6% was neither additive nor antagonistic to the ocular hypotensive efficacy of bimatoprost.     

An experimental study of the ocular hypotensive action of dopaminergic antagonists

The ocular hypotensive action of a group of dopaminergic antagonists was observed in the low intraocular pressure model of albino rabbits infused with 20% NaCl. It was found that haloperidol lowered IOP significantly in both eyes, though the drug was administered in one eye. Compared with timolol and pilocarpine, the strength in lowering IOP was in the order haloperidol greater than timolol greater than pilocarpine. Haloperidol did not affect the pupil. It may be a promising antiglaucoma agent.     

Effects of travoprost on aqueous humor dynamics in patients with elevated intraocular pressure

PURPOSE: To determine the mechanism by which travoprost 0.004% reduces intraocular pressure (IOP) in patients with ocular hypertension or primary open angle glaucoma. DESIGN: This is a randomized, double-masked, placebo-controlled, single center study of 26 patients scheduled for 3 visits (baseline, day 15, and days 17 to 18) following screening. METHODS: After appropriate washout of all ocular medications, baseline IOPs were taken and travoprost 0.004% was administered once-daily in the evening for 17 consecutive doses to 1 eye and its vehicle to the fellow eye in a randomized, masked fashion. On day 15, beginning 12 hours after the 14th consecutive dose, IOP was measured by pneumatonometry, aqueous flow and outflow facility by fluorophotometry, and episcleral venous pressure by venomanometry. Uveoscleral outflow was determined by mathematical calculation. Two days later, the last drop of drug/vehicle was given at 2000 hours. Fluorophotometry and tonometry measurements were repeated between 2200 and 0600 hours. Treated eyes were compared with contralateral control eyes or baseline measurements, and daytime measurements were compared with nighttime measurements using paired t tests. RESULTS: Travoprost-treated eyes showed a significant (P<0.001) decrease in daytime IOP compared with baseline (26%) or to vehicle-treated eyes (22%), and an increase in daytime outflow facility (P=0.001; 64%). The increase in uveoscleral outflow was not statistically significant. At night, the IOPs of travoprost-treated eyes remained 21% to 24% below baseline daytime values. Seated and supine IOPs in control eyes were significantly (P<0.04) lower at 2200 hours than 1700 hours (P<0.04). Supine IOPs were higher than seated IOPs in both control and treated eyes (P<0.001). Aqueous flow was significantly (P<0.001) reduced at night in both travoprost (30%) and vehicle-treated (25%) eyes when compared with daytime values. No other comparisons were statistically significant. CONCLUSIONS: Travoprost seems to lower IOP by increasing trabecular outflow facility. An effect on uveoscleral outflow cannot be ruled out.     

The effect on diurnal intraocular pressure of the fixed combination of latanoprost 0.005% and timolol 0.5% in patients with ocular hypertension

PURPOSE: To measure the effect on intraocular pressure (IOP) after single-dose administration of the fixed combination of latanoprost 0.005% and timolol 0.5%. METHODS: A randomized, double-masked placebo-controlled parallel-group study was carried out. Twenty patients with ocular hypertension received the fixed combination of latanoprost+timolol, while 10 received placebo eyedrops. On baseline day no eyedrops were given, but IOP was measured repeatedly between 8.00 a.m. and 8.00 p.m. On Day 7 the eyedrops were given at 8.00 a.m., and IOP measured as on baseline day. On Day 8 and Day 9, IOP was again measured at 8.00 a.m. RESULTS: There was no difference in IOP in the placebo group. In the latanoprost+timolol group maximal IOP reduction (12.4+/-2.8 mmHg; mean+/-standard deviation) occurred 6.4 hours after drug administration (5.2--7.7 hours; 95% confidence interval [CI]). The mean IOP reduction after 24 hours was 9.8 mmHg (7.4--12.2 mmHg; 95% CI; p<0.001), and after 48 hours 5.7 mmHg (3.4--8.1 mmHg; 95% CI; p<0.001). CONCLUSIONS: The fixed combination of latanoprost+timolol statistically significantly reduced IOP after single-dose administration. The maximal effect was noted after about 6 hours, and the IOP reduction was still pronounced after 48 hours.     

Silicone punctal plugs as an adjunctive therapy for open‐angle glaucoma and ocular hypertension

Background: Primary open‐angle glaucoma is a progressive optic neuropathy that can cause an irreversible loss of vision. A reduction in intraocular pressure (IOP) is beneficial in slowing or halting its progression. Once‐per‐day monotherapy glaucoma medications, such as prostaglandin analogues, are effective in lowering IOP while maintaining patients' adherence. Achieving the desired target IOP often requires multiple medications. The present study evaluates punctal occlusion of both the inferior and superior puncta as an adjunctive therapy to travoprost ophthalmic solution 0.004% for patients with primary open‐angle glaucoma or ocular hypertension in order to reduce IOP. Methods: Thirteen patients who were using travoprost 0.004% ophthalmic solution for the treatment of open‐angle glaucoma or ocular hypertension received silicone punctal plugs in the superior and inferior puncta of one eye. After one month, the IOP was remeasured. The percentage change of the IOP from the baseline was analysed by using a paired sample t‐test. Results: The mean baseline IOP was 19.82 ± 1.19 mmHg in the test eyes and 18.32 ± 1.11 mmHg in the control eyes. The mean IOP at the one‐month visit was 18.23 ± 1.17 mmHg in the test eyes and 18.45 ± 1.04 mmHg in the control eyes. The test eyes demonstrated a decrease in IOP of 1.59 (± 0.95) mmHg from the baseline, or a 6.82 per cent decrease in the IOP from the baseline. The control eyes had an increase in IOP of 0.14 ± 0.77 mmHg from the baseline, or a 1.91 per cent increase in the IOP. The relative difference in the IOP between the test eyes and the control eyes at the one‐month visit was 1.73 mmHg, or 8.74 per cent. Conclusion: Based on the results of this study, punctal occlusion offers a statistically and clinically significant decrease in IOP when it is used as an adjunctive therapy to travoprost 0.004% for patients who are suffering from open‐angle glaucoma or ocular hypertension.
