PURPOSE: The primary objective of this study was to determine the intraocular pressure- (IOP) lowering efficacy over two consecutive 24-h periods of travoprost 0.004% ophthalmic solution (Travatan) compared to latanoprost 0.005% (Xalatan) dosed once daily in patients with primary open-angle glaucoma or ocular hypertension. METHODS: This was a double-masked trial conducted at the Hospital Clínico San Carlos, Madrid, Spain. The primary objective of this study was to determine the IOP lowering efficacy of travoprost and latanoprost. During the eligibility visit, patients' IOP was measured throughout two consecutive 24-h periods every 4 h. Patients were then randomized to travoprost or latanoprost (one drop at 8 p.m. daily for 2 weeks). Sixty-two patients were randomized (travoprost n = 32; latanoprost n = 30). IOP was measured at week 2 every 4 h throughout two 24-h periods. All measurements were taken in both supine and sitting positions with the aid of Perkins applanation tonometry. Limitations of the study include a small sample size (due to the difficulty in recruiting patients in a study of this type) which enrolled only Caucasian patients and a short study duration. However, with 25 subjects per group, there was at least 90% power to detect a mean IOP change from baseline of 2.9 mmHg and 80% power to detect a difference of 2.5 mmHg between treatments. RESULTS: Patients on travoprost therapy showed lower mean IOP levels than those on latanoprost. This difference was statistically significant (p < 0.05) at 12, 16, 20, 24, 36, 40, and 48 h after the last dose for the supine position. The mean IOPs in the supine position throughout the first and the second 24-h period of the week 2 visit as well as for the 48-h visit were statistically lower (p < 0.05) for the travoprost group. Adverse events were mild and included hyperemia and corneal staining. Travoprost and latanoprost were both well tolerated. CONCLUSION: Mean IOP values were significantly lower for patients on travoprost for the majority of time points in the supine position. 相似文献

SUMMARYObjective: To evaluate the efficacy of travoprost 0.004% monotherapy in patients unsuccessfully treated with latanoprost monotherapy.Research design and methods: Open-label, non-comparative study conducted at US academic and private practice clinics in adult patients with ocular hypertension or primary open-angle glaucoma who required a change in therapy (due to either inadequate efficacy or safety issues) as judged by the investigator. Intraocular pressure (IOP) was measured at entry and 30?days later.Main outcome measures: Mean change in intra-ocular pressure (mm Hg).Results: Reported here are 488 per-protocol patients from 330 centers who were using latanoprost monotherapy prior to study entry, and who received travoprost monotherapy during the study. Patients had a mean age of 69?years, were approximately two-thirds Caucasian, 60% female, predominantly brown or blue eyes, and 91% were diagnosed as having primary open-angle glaucoma. The mean days in treatment were 31.9 ± 6.4. Mean IOP at study entry was 21.2?mm Hg. Following travoprost monotherapy, this was reduced by a mean of 3.2?mm Hg to 18?mm Hg (?p < 0.0001, paired t-test). There were 21 adverse events reported in the intent-to-treat (ITT) population for an incidence of 3.5%. There were some limitations to the current study including: no washout period, no control therapy, single IOP determinations at the beginning and the end of the study; patient compliance with the initial therapy was not measured, and the study was not masked. This study reflects a real-life situation of what a clinician can expect when he changes a patient from latanoprost monotherapy to travoprost monotherapy.Conclusion: This study showed that travoprost provided a statistically and clinically significant reduction (?p < 0.0001) in IOP of 3.2?mm Hg for patients who had not been successfully treated with latanoprost monotherapy. The results of this trial demonstrate the potential benefit of using travoprost as a replacement therapy in order to ensure adequate IOP control. 相似文献

ABSTRACTObjective: The objective of this review was to evaluate different measures of efficacy of the intraocular pressure (IOP) lowering lipid class agents bimatoprost, latanoprost and travoprost in the treatment of primary open angle glaucoma. Study arms of timolol in trials including the above mentioned lipid class drugs were also included.Methods: MEDLINE and EMBASE were searched for randomized clinical trials including one or more of the lipid class drugs bimatoprost, latanoprost and travoprost. The study results were pooled, and the simple, weighted IOP-lowering efficacy was compared among the lipid class drugs and timolol, where data were available. Efficacy parameters were reviewed, including mean reduction of IOP and percentage of patients achieving different levels of IOP.Results: 161 articles were identified of which 42 were included in the analysis. A total of 9295 patients participated in the included trials. Based on all studies, timolol on average had a weighted mean IOP reduction of 22.2%, while latanoprost, travoprost and bimatoprost had a weighted mean IOP reduction of 26.7%, 28.7% and 30.3%, respectively. Analysis of target achievement to various IOP levels shows that bimatoprost seems more efficacious than latanoprost. The direct comparisons (head-to-head studies) also show that bimatoprost is the most efficacious treatment, however it is not conclusive whether latanoprost or travoprost is better in reducing IOP.Conclusions: This review shows that bimatoprost seems to be the most efficacious treatment in lowering IOP. Head-to-head studies confirm this. 相似文献

ABSTRACTObjective: To compare the IOP-lowering efficacy of a.m.-dosed travoprost and latanoprost at 24-h post-dose.Research design and methods: Open-angle glaucoma patients not naïve to prostaglandin therapy and currently controlled on p.m.-dosed (2100) latanoprost (n?=?21) or travoprost (n?=?30) had baseline IOPs measured at 0900. In a randomized, single-masked, crossover design, patients received travoprost (Travatan) or latanoprost (Xalatan) at 0900 for 4?weeks, then were crossed over to receive the second prostaglandin for another 4?weeks. Treatment IOP was measured at 0900 prior to morning dose at both 4 and 8?week visits. Patient dosing preference (a.m./p.m.) was surveyed on exit.Main outcome measure: Intraocular pressure (IOP). Results: The mean IOP in the first period when all patients were dosed in the evening was assessed 12?h after dosing at 09:00 and it was similar in the two treatment groups (mean?±?standard deviation: 17.9?±?2.7?mmHg for travoprost versus 17.7?±?2.5?mmHg for latanoprost, p?=?0.812). In the a.m.-dosing crossover comparison, the 24-h post-dose IOP was significantly lower (?p?<?0.001) on travoprost (16.9?±?3.1?mmHg) compared to latanoprost (18.6?±?3.3?mmHg). In the exit survey, 51% of patients preferred a.m.-dosing.Conclusions: a.m.-dosed travoprost is superior to a.m.-dosed latanoprost by 1.7?mmHg at 24-h post-dose. 相似文献

Abstract
Objective:
Tafluprost, the first preservative-free prostaglandin analogue for topical ophthalmic use to lower IOP, was introduced in Germany in 2008. After the approval for ophthalmic use, an open-label, multicentre, observational study was conducted between October 2008 and April 2009. Major objectives of this study were to evaluate the real world efficacy, local tolerability and safety of this first in class preservative-free prostaglandin preparation in patients with ocular hypertension and glaucoma. 相似文献7.

SUMMARYPurpose: To compare the efficacy and safety of the concomitant administration of travoprost 0.004% once daily and brinzolamide 0.1% twice daily with those of a fixed combination of latanoprost 0.005%/timolol 0.5% once daily.Research, design and methods: Forty-four patients with primary open-angle glaucoma or ocular hypertension with elevated IOP insufficiently responsive to monotherapy were randomly assigned to one of the two treatment groups: concomitant administration of travoprost 0.004% once daily and brinzolamide 0.1% twice daily (TB group: 22 patients) or latanoprost 0.005% plus timolol 0.5% once daily (LT group: 22 patients). Visits were undertaken at screening (current ocular hypotensive therapy was discontinued), baseline (randomization), and after 2 weeks, 1 month, 2 months and 3 months of therapy.Main outcome measures: IOP was determined at 9 a.m., 12 p.m. and 4 p.m. at each study visit, and diurnal IOP was calculated as the mean of these recordings. Adverse events were recorded at each visit.Results: IOP at the baseline visit was similar in both groups. Overall mean IOP was significantly lower in the TB as compared to the LT group after 1?month, 2?month and 3?month follow-up; only 9 a.m. measurements were significantly different, reaching a maximum difference (16.9 ± 0.9?mmHg vs 18.4 ± 1.8?mmHg, p < 0.001) at the 3?month check. The percentage of responders (IOP decrease ≥ 30%) was higher in the TB group. Both treatments were well tolerated and there were no cases of withdrawal from treatment.Conclusions: Travoprost 0.004% and brinzolamide 0.1% concomitant therapy showed a greater efficacy than the fixed latanoprost 0.005%/timolol 0.5% combination in terms of absolute IOP decreases. Travoprost/brinzolamide therapy also offered the advantages of a greater percentage of responders. 相似文献

ABSTRACTPurpose: The purpose of this study was to compare travoprost (TRAV; travoprost 0.004%) and the fixed-combination of dorzolamide/timolol (DTFC; dorzolamide 2.0%/timolol maleate 0.5%) ophthalmic solutions for reducing intraocular pressure (IOP) in patients with primary open-angle glaucoma (OAG) or ocular hypertension (OHT).Methods: This was a randomized single masked, study with parallel controls. The TRAV group (n = 29) dosed once daily at 9:00 PM while the DTFC group (n = 27) dosed twice daily at 9:00 AM and 9:00 PM. IOP was measured at baseline, and following 3 weeks and 6 weeks of treatment at 8:00 AM, 12:00 PM, 4:00 PM, and 8:00 PM.Results: Mean average IOP reductions from baseline during the course of the day were 7.5 (32.7%) and 7.1 (30.7%)?mmHg for TRAV and 4.8 (23.1%) and 4.5 (21.7%)?mmHg for DTFC at 3 weeks and 6 weeks, respectively. The greater IOP reduction for patients receiving TRAV was statistically significant at both the 3 and 6 week visits when averaged across all four time points (?p < 0.01). The two products were well-tolerated over the course of the 6 week study. Some factors such as taste perversion were reported more often in the DTFC group.Conclusions: Travoprost monotherapy provided better efficacy in terms of IOP reduction and per-centage of IOP reduction compared to dorzolamide 2.0%/timolol maleate 0.5% fixed combination. 相似文献

ABSTRACTObjective: To compare the intraocular pressurelowering efficacy and safety of topical bimatoprost 0.03% with that of travoprost 0.004% for the reatment of black patients with open-angle glaucoma (OAG) and ocular hypertension (OHT).Research design and methods: Multicenter, prospective, randomized, investigator-masked trial of 94 black patients previously diagnosed with OAG or OHT. All patients completed washout of ocular hypotensive medications before study participation. Patients were assigned to either once-daily bimatoprost 0.03% or once-daily travoprost 0.004% for 3 months.Main outcome measures: The primary outcome measures were mean intraocular pressure (IOP), mean change from baseline IOP, and percentage of patients who reached a target IOP reduction. Secondary measures included ophthalmologic examination and adverse events.Results: Both bimatoprost and travoprost significantly lowered IOP at all study visits (?p < 0.001). Bimatoprost provided mean IOP reductions from baseline that ranged from 6.8?mmHg to 7.8?mmHg (27% to 31%). Travoprost provided mean IOP reductions from baseline that ranged from 6.2?mmHg to 6.9?mmHg (25% to 28%). By month 3, 85% of participants in the bimatoprost group had a mean IOP reduction of at least 20%, compared with 68% of those in the travoprost group. Furthermore, 31.9% of those in the bimatoprost group had a mean IOP reduction of more than 40% at month 3 compared with 20.9% of those in the travoprost group. There were no significant differences in biomicroscopy, ophthalmoscopy, or visual acuity. Ocular redness was the most commonly reported adverse event in both treatment groups. No serious adverse events were reported.Conclusions: Bimatoprost and travoprost each effectively lowered IOP in this population of black patients. More patients achieved clinically relevant IOP reductions with bimatoprost. 相似文献

ABSTRACTObjective: To evaluate the 24-hour efficacy and tolerability of 2% dorzolamide/0.5% timolol fixed combination (DTFC) solution in open-angle glaucoma and ocular hypertension.Research design and methods: Randomized, parallel, doublemasked, multicenter study. Patients with insufficiently controlled intraocular pressure (IOP≥22 mmHg) were randomized to DTFC (N=117) or timolol (N=115). IOP was measured at baseline, 6 weeks, and 8 weeks, with measurements taken at 6 p.m., 8 p.m., 10 p.m., 2 a.m., 6 a.m., 8 a.m., 10 a.m., and 2 p.m.Main outcome measures: Statistically significant change in IOP from untreated baseline for DTFC at all hours at week 8. Secondary outcome measures included: IOP-lowering at week 6 at all individual time points, change from baseline to 8 weeks in mean daytime IOP (average of 8 a.m., 10 a.m., 2 p.m., 6 p.m., and 8 p.m. IOPs) and night-time IOP (10 p.m., 2 a.m., 6 a.m.), and comparison of DTFC with timolol after 8 weeks.Results: Patients receiving DTFC had a statistically significant and clinically relevant reduction in IOP at week 8 compared with baseline at all eight time points (p<0.001). Significant IOP reductions were also seen at all time points at week 6 (p<0.001). DTFC significantly lowered mean daytime IOP and night-time IOP (p<0.001 for both). Timolol alone also significantly reduced IOP from baseline at 8 weeks for all diurnal time points, and mean daytime and night-time IOP (p<0.001 for all). Compared with timolol alone, there were significantly greater reductions with DTFC at 10 a.m. (p=0.003) and 2 p.m. (p=0.016), and for mean daytime IOP (p=0.025) at 8 weeks. Significant between-treatment differences were not observed at other time points. Both treatments were well-tolerated, with no differences observed in the safety profiles between the treatment groups.Conclusions: Both DTFC and timolol provided significant IOP reduction over the entire 24-hour measurement period. timolol during the daytime, but not at night. Although this study was not designed or powered to compare DTFC and timolol, DTFC exhibited greater IOP-lowering than timolol during the daytime, but not at night.Trial registration: ClinicalTrials.gov identifier: NCT00108017. 相似文献

ABSTRACTObjective: To evaluate the efficacy and tolerability of brimonidine purite 0.1% in comparison to brinzolamide 1% when used as adjunctive therapy to latanoprost 0.005% in patients with glaucoma or ocular hypertension.Methods: Randomized, single-center, investigator-masked, parallel-group clinical study. Patients with IOP?≥?18?mmHg while on once-daily latanoprost were randomized to adjunctive treatment with brimonidine purite TID (n?=?20) or brinzolamide TID (n?=?20) for 3 months. Intraocular pressure (IOP) was measured at 8 a.m., 10 a.m., and 4 p.m. at latanoprost-treated baseline and after 1 and 3 months of latanoprost and adjunctive therapy. A patient questionnaire was administered to evaluate the tolerability of eye drop instillation.Results: Baseline mean diurnal IOP (± standard deviation, mmHg) on latanoprost was comparable between groups (brimonidine purite: 19.6?±?2.94; brinzolamide: 19.8?±?3.25; p = 0.846). Mean diurnal IOP at Month 3 was 16.3?±?2.63?mmHg with brimonidine purite and 17.8?±?2.19?mmHg with brinzolamide (?p = 0.028). Adjunctive use of brimonidine purite provided greater IOP lowering than brinzolamide at 10 a.m. (?p < 0.001) and 4 p.m. (?p = 0.050) and equivalent IOP lowering to brinzolamide at 8 a.m. (?p = 0.716). Blurred vision at Month 1 and bitter taste at Months 1 and 3 were more common upon instillation of brinzolamide eye drops.Conclusion: Brimonidine purite 0.1% provided significantly lower IOP compared with brinzolamide 1% when used as adjunctive therapy to latanoprost. Both adjunctive therapies were well tolerated. Limitations of this study include the use of a single site and the sample size. Additional studies are needed to further evaluate these drugs as adjunctive therapy to prostaglandin analogs. 相似文献

ABSTRACTObjective: To investigate the influence of switching to travoprost on intraocular pressure (IOP) of chronic open-angle glaucoma (COAG) patients.Research design and methods: Multicentre, open-label, non-comparative, 12‐week, phase IV study conducted at 10 academic and hospital centres in Hungary. Patients’ compliance to use of the pre-study medication was confirmed at a visit 10 days before the baseline measurements, and compliance was monitored throughout the study period.Results: Of the 203 COAG patients three (1.48%) ceased travoprost medication due to ocular hyperaemia, and one subject was lost from follow-up. Self-reported compliance was optimal except for two patients. For the per-protocol analysis 197 patients were evaluable. IOP of the 37 per-protocol patients receiving additional travoprost medication decreased from 23.1 ± 3.2?mmHg (mean ± SD) to 17.3 ± 2.6?mmHg at week 12 (?p < 0.001). Switching the 121 per-protocol patients from latanoprost to travoprost IOP decrease from 20.8 ± 3.5?mmHg to 17.7 ± 2.4?mmHg (?p < 0.001). IOP of the 11 patients switched from topical non-selective beta-blockers to travoprost decreased from 20.1 ± 2.1?mmHg to 15.7 ± 1.5?mmHg (?p < 0.001). For the whole per-protocol population (n = 197) IOP decreased from 21.0 ± 3.4?mmHg to 17.4 ± 2.4?mmHg (?p < 0.001). Defining responders as having an IOP decrease > 2.0?mmHg or ≥ 5?mmHg at week 12, the responder rate was respectively 62.9% or 31% for the total study population; 86.5% or 54.1% when travoprost was added to the established therapy; 54.5% or 24.0% if latanoprost was switched to travoprost; and 90.9% or 36.4% for those who switched from beta-blockers.Conclusion: Travoprost provided a clinically and statistically significant IOP decrease in uncontrolled COAG patients whose self-reported compliance to their previous topical medication was optimal. Our results suggest that the IOP reduction found after switching to travoprost is not explainable by improved compliance due to the clinical study situation. 相似文献

ABSTRACTObjective: To investigate if combined intraocular pressure (IOP)-lowering medication with travoprost/timolol fixed combination and a carbonic anhydrase inhibitor, brinzolamide, is superior to both travoprost monotherapy and travoprost/timolol fixed-combination therapy in primary open-angle glaucoma and ocular hypertension.Methods: Following a 4-week wash-out period and using 4-week long treatment periods, 20 primary open-angle glaucoma or ocular hypertension patients were treated with evening travoprost 0.004?%?, then switched to evening travoprost 0.004?%?/timolol 0.5?%?fixed combination, and finally the treatment was combined with adjunctive twice-daily brinzolamide 1?%?ophthalmic suspension. Both eyes were treated, but only one eye per patient (the eye with the higher mean diurnal IOP at baseline), was evaluated. IOP was measured at 8 a.m., 12 noon and 4 p.m. at baseline and at the end of each treatment period.Results: Mean diurnal IOP (mean (SD)) at baseline was 28.5 (7.3) mmHg which decreased to 22.3 (6.3) mmHg on travoprost, 19.2 (3.4) mmHg on travoprost/timolol fixed combination and 17.3 (3.4) mmHg when the brinzolamide was added to the travoprost/timolol combination (ANOVA, contrast test, p?<?0.003 for all comparisons). The individual time point IOP values showed similar and significant stepwise differences.Conclusion: Adjunctive brinzolamide medication provided further IOP decrease in patients receiving evening-dosed travoprost/timolol fixed combination. The travoprost/timolol fixed combination was significantly more effective in IOP reduction than travoprost monotherapy, which by itself induced a significant IOP decrease compared to the untreated baseline value. The results of this open label study suggest that combined therapy with travoprost/timolol fixed combination and brinzolamide is clinically useful for IOP-lowering in primary open-angle glaucoma and ocular hypertension. 相似文献

ABSTRACTObjective: The objective of this cost-effectiveness analysis is to evaluate cost-effectiveness ratios of the intraocular pressure (IOP)-lowering agents bimatoprost, latanoprost and timolol in five major European countries: France, Germany, Italy, Spain and the UK.Methods: The cost-effectiveness analysis is based on achievement of IOP targets between 13 and 18?mm Hg. Thus, the cost-effectiveness ratios express the costs of having one patient successfully achieving IOP target. The perspective of the analysis is that of the health care sector payer, including costs of medicine and costs of ophthalmologist visits. The time frame is first year of glaucoma treatment. Four treatment strategies are analysed: Timolol as first line with add-on latanoprost or bimatoprost if IOP targets are not met, and latanoprost and bimatoprost as first line with add-on timolol.Results: In the UK, Spain, Italy and Germany the timolol first with add-on of bimatoprost is the least expensive treatment. This strategy dominates both strategies involving latanoprost (as add-on to timolol or as first line) in these four countries. The incremental cost-effectiveness ratio of bimatoprost first-line therapy versus timolol with add-on bimatoprost varies from each country and target (from £305 to €43 720 per patient). In France the timolol first line and latanoprost add-on is not dominated and is the cheapest alternative. The incremental cost-effectiveness ratio of timolol with add-on bimatoprost versus add-on latanoprost lies between £71 and €355 per patient depending on target (18 and 13?mm Hg, respectively).Conclusion: First-line treatment of latanoprost is dominated in all countries. In four out of five countries the timolol first-line therapy with add-on latanoprost is also dominated. Based on this pharmacoeconomic analysis, the most costeffective strategy seems to be timolol first line with add-on bimatoprost if target is not met after 3 months. 相似文献

ABSTRACTIntroduction: The only evidence-based mechanism for prevention and treatment of glaucomatous optic neuropathy is decreasing the intraocular pressure (IOP). Prescribing multiple ocular hypotensive agents, such as the combination of carteolol and latanoprost, may synergistically improve IOP; however, doing so may increase the complexity of a medication regimen, in turn, impairing patient adherence. Fixed-combination glaucoma medications offer convenience and effectiveness. New to this class of glaucoma medication is fixed combination carteolol-latanoprost (FCCL).Area covered: This review intends to give the reader a better understanding of the efficacy of the combination of carteolol and latanoprost separately, and where FCCL fits into the vast medical arsenal of IOP drops. Furthermore, it outlines the particular pharmacologic mechanisms targeted, the pharmacokinetics, effectiveness, the advantages of fixed-combination administration, and tolerability.Expert opinion: The combination of carteolol and latanoprost, separately or in a fixed-combination, is more effective than either drug alone. Given the early stage in development of FCCL, it has yet to be determined how FCCL compares to other fixed-combination medications. However, pending further approval, fixed-combination carteolol-latanoprost may represent a reasonable alternative for a patient whose IOP is inadequately controlled on a prostaglandin analog alone and for whom a simplified combination is preferred. 相似文献

ABSTRACTObjective:?To assess the effects of dorzolamide/timolol fixed combination (DTFC) and latanoprost 0.005% on the retrobulbar haemodynamics and intraocular pressure (IOP) of open-angle glaucoma patients.Methods:?22 consecutive subjects with newly diagnosed, open-angle glaucoma were included in this prospective, examiner masked, randomized, crossover study. The patients were randomized into two different arms. Peak systolic velocity (PSV), end-diastolic velocity (EDV), Pourcelot's resistance index (RI) and intraocular pressure (IOP) were determined at baseline and after 1 month of medical treatment with DTFC or latanoprost 0.005% in both groups. A 4‐week washout period, without medical treatment, between study arms was carried out. Primary efficacy variables were the PSV, EDV and RI in the ophthalmic artery (OA) and short posterior ciliary artery (SPCA) and intraocular pressure (IOP). Inter- and intra-group comparisons were performed with a one-way ANOVA test and two-tailed paired Student's t-test respectively.Results:?Intraocular pressure (IOP) and colour Doppler imaging (CDI) measurements were similar at baseline. Compared to baseline and washout measurements, only the fixed combination dorzolamide/timolol significantly increased the EDV in the OA and in the SPCA, p = 0.00012 and p = 0.00012, respectively and decreased the resistance index in the ophthalmic and short posterior ciliary arteries, p = 0.00011 and p = 0.00031, respectively. There were no statistically significant differences in the IOP lowering effect of either treatment.Conclusion:?Over a treatment period of 1 month, only the fixed combination dorzolamide/timolol seems to have a vascular effect on retrobulbar vessels. Further research is necessary to confirm these results. 相似文献
