tafluprost and Low-Tension-Glaucoma

A prospective study was performed to compare the ocular pulse amplitude (OPA)-lowering effects of tafluprost and latanoprost, used in the treatment of glaucoma, using dynamic contour tonometry.. The study population consisted of patients with normal-tension glaucoma (NTG) (n = 27) or primary open-angle glaucoma (POAG) (n = 14) treated with tafluprost and latanoprost. All patients were newly diagnosed with NTG and POAG and had undergone no previous treatment. Intraocular pressure (IOP) was measured by Goldmann applanation tonometry (GAT), OPA was measured by dynamic contour tonometry, and corrected OPA (cOPA) was calculated before and after 1 week, 1-3 months of treatment.. Initial IOP and OPA were 17.12 ± 3.75, 2.30 ± 0.56 mmHg and 17.53 ± 2.87, 2.65 ± 0.94 mmHg in the tafluprost and latanoprost groups, respectively. After 3 months of treatment, IOP and OPA were 13.00 ± 2.04 mmHg (24.1%) and 1.51 ± 0.30 mmHg (34.3%), respectively, in the tafluprost group. These values were 15.40 ± 2.32 mmHg (12.2%) and 2.08 ± 0.83 mmHg (21.5%), respectively, in the latanoprost group. Therefore, tafluprost significantly reduced IOP (P = 0.01), but OPA-lowering effects did not differ significantly between the 2 groups (P = 0.17). However, the cOPA-lowering effect of tafluprost (1.27 mmHg, 55.2%) was significantly greater than that of latanoprost (0.84 mmHg, 31.7%) after 3 months of treatment (P < 0.001).. Tafluprost and latanoprost, used to treat glaucoma, have marked OPA-lowering effects as well as IOP-lowering effects. Moreover, tafluprost has a greater effect than latanoprost. Therefore, it can be used for patients in need of IOP reduction and at risk of glaucoma progression.

To compare the 24-h changes of intraocular pressure (IOP) and mean ocular perfusion pressure (MOPP) obtained with tafluprost versus travoprost in patients with normal-tension glaucoma (NTG).. This study is a randomized crossover study of 50 patients newly diagnosed with NTG who received either tafluprost or travoprost given once at 9 PM for 2 months, after which they were crossed over to the other medication for another 2 months. IOP and blood pressure were measured for 24 h before starting the treatment and after finishing the first and second treatment periods.. Forty-one patients completed the study. The mean (±standard deviation) 24-h IOP was 16.8±2.0 mmHg at baseline, 14.4±2.2 mmHg on tafluprost, and 13.6±1.8 mmHg on travoprost. Both prostaglandin monotherapies significantly reduced mean 24-h IOP as compared with baseline (P<0.001, P<0.001, respectively), and travoprost demonstrated a lower mean 24-h IOP than tafluprost (P=0.044). Both treatments significantly reduced the IOP from baseline at every point over 24 h. At 3 individual time points, travoprost provided a lower IOP than tafluprost: at 4 PM (13.8±2.7 vs. 14.8±2.6 mmHg, P=0.041), at 6 PM (13.5±2.5 vs. 14.4±2.5 mmHg, P=0.006), and at 8 PM (13.3±2.5 vs. 14.5±2.4 mmHg, P=0.029). Both tafluprost and travoprost significantly increased the 24-h MOPP (P=0.008, P=0.002, respectively), and travoprost demonstrated a greater 24-h MOPP than tafluprost (P=0.027).. Both tafluprost and travoprost were effective in lowering IOP and increasing MOPP throughout 24 h in NTG. However, travoprost reduced IOP greater than tafluprost in the late afternoon and evening.

To compare the efficacy and safety of 0.0015% tafluprost ophthalmic solution (Tafluprost) with Placebo ophthalmic solution (Placebo) in normal tension glaucoma (NTG).. Total of 94 patients enrolled in a randomized, double-blind, parallel-group and multicenter study.. Patients with NTG were randomly assigned to either Tafluprost or Placebo. Both ophthalmic solutions were instilled once a day in the morning for 4 weeks.. Mean intraocular pressure (IOP) changes from baseline were -4.0 +/- 1.7 mmHg in Tafluprost administered patients and -1.4 +/- 1.8 mmHg in Placebo administered patients at 4 weeks, with a statistically significant difference (p<0.001). IOP change at 4 weeks, % IOP reduction at 2 and 4 weeks were also significantly greater in Tafluprost than in Placebo. A total of 51.0% in Tafluprost treated group and 8.9% in Placebo treated group reported adverse drug reactions.. These results indicate that Tafluprost is clinically useful in the treatment of NTG.

The aim of this study was to investigate the long-term intraocular pressure (IOP)-lowering effect and safety of tafluprost, a prostaglandin analogue, in actual clinical practice and to determine persistency of tafluprost as an indicator of its benefit-risk balance.. This was a large-scale, post-marketing, multicenter, non-interventional, open-label, long-term study. Patients with glaucoma or ocular hypertension who initiated tafluprost treatment were registered and prospectively observed over a 2-year period in the real-world setting in Japan. Long-term IOP and safety data were collected.. Of the 4502 patients registered from 553 medical institutions, 4265 patients were analyzed. The majority of patients had normal-tension glaucoma (44.4%) and primary open-angle glaucoma (37.8%), and patients with ocular hypertension constituted 7.0%. Treatment patterns with tafluprost during the study period were as follows: naïve monotherapy (48.1%), switching monotherapy (18.4%), and concomitant therapy (33.5%). In all patients analyzed, mean IOP was significantly reduced from 18.6 ± 5.9 mmHg (month 0) to 15 mmHg or below throughout the 2-year observation period after initiation of tafluprost. Significant IOP-lowering effects were shown in various treatment patterns and disease types. Adverse reactions were observed in 795 patients (18.64%). Major adverse reactions included eyelid pigmentation, ocular hyperemia, eyelash changes, eyelid hypertrichosis, and iris hyperpigmentation. Kaplan-Meier curves showed that 84.6% and 76.1% of patients were persistent on tafluprost for 1 and 2 years, respectively, when discontinuation due to insufficient efficacy or adverse events was defined as a treatment failure event. Furthermore, among treatment-naïve patients (n = 2304), the persistency rates on tafluprost monotherapy were 77.0% for 1 year and 67.0% for 2 years.. Tafluprost showed significant long-term IOP-lowering effects regardless of treatment patterns or diagnosis, with minimum safety concerns in the actual clinical practice. The observed treatment persistence suggests that tafluprost can be used long term owing to its benefit-risk profile.. Santen Pharmaceutical Co., Ltd., Osaka, Japan.

To compare the ocular pulse amplitude (OPA) lowering effects of preservative-free tafluprost and dorzolamide-timolol fixed combination (DTFC) using dynamic contour tonometry.. In total, 66 eyes of 66 patients with normal tension glaucoma (NTG) (n = 34) or primary open angle glaucoma (POAG) (n = 32) were included. Patients were divided into two groups: the preservative-free tafluprost-treated group (n = 33) and the preservative-free DTFC-treated group (n = 33). Intraocular pressure (IOP) was measured using Goldmann applanation tonometry (GAT). OPA was measured using dynamic contour tonometry; corrected OPA (cOPA) was calculated at baseline and at 1 week and 1, 3, and 6 months after treatment.. After 6 months of treatment, tafluprost significantly reduced IOP (P < 0.001). The OPA lowering effects differed significantly between the two treatment groups (P = 0.003). The cOPA-lowering effect of tafluprost (1.09 mmHg) was significantly greater than that of DTFC (0.36 mmHg) after 6 months of treatment (P = 0.01).. Tafluprost and DTFC glaucoma treatments provided marked OPA and IOP lowering effects. Tafluprost had a greater effect than DTFC; thus, this drug is recommended for patients at risk of glaucoma progression, due to the high OPA caused by large fluctuations in IOP.

Deepening of the upper eyelid sulcus (DUES), one symptom of prostaglandin-associated periorbitopathy, was recently found to be an additional side effect of prostaglandin-related ophthalmic solutions. Here, we prospectively investigated the incidence and factors associated with DUES in Japanese open-angle glaucoma patients initially treated with benzalkonium chloride (BAK)-preserved tafluprost (TAF).. In this open-label prospective study instilling TAF in one eye, mean deviation (MD) and intraocular pressure (IOP) were measured, and facial photographs and subjective reports of DUES were obtained at intervals over 6 months. Three ophthalmologists independently assessed the photographs of DUES and reached consensus. Relationships between demographic and ocular/systemic factors (age, sex, MD, refraction and IOP reduction) and DUES occurrence were evaluated.. Forty-three eyes of 43 glaucoma patients (24 men and 19 women) were evaluated. Mean IOP before treatment was 16.6 ± 2.7 and after treatment, 14.1 ± 2.3 mmHg (P < 0.001). The objective rate of DUES was 9 % (4/43) at 2 months, 14 % (6/43) at 4 months and 14 % (6/43) at 6 months. During this period, only one patient self-reported an occurrence of DUES. No significant association was found between DUES occurrence and any of the demographic, ocular, or systemic factors.. Physicians should inform patients about DUES as a minor side effect when prescribing TAF for IOP control.

To evaluate the intraocular pressure (IOP)-reducing effects and safety of 0.0015% tafluprost ophthalmic solution (tafluprost) in normal-tension glaucoma (NTG) patients with an IOP of 16 mmHg or less.. NTG patients with a baseline IOP of 16 mmHg or less were enrolled for a one-eye study in which tafluprost was applied once daily for 12 weeks. The presence of adverse drug reactions and the cumulative incidence of adverse events were also investigated.. Among the 44 enrolled patients, 41/44 (93.2%) eyes completed the study. The baseline IOP was 13.2 ± 1.3 mmHg in the study eyes and 13.0 ± 1.3 mmHg in the fellow eyes, which was not statistically significant (P = 0.9173, Student's t test). The values obtained for IOP in the study eyes versus fellow eyes were 10.2 ± 1.6 versus 12.1 ± 1.5 mmHg at week 12. The IOP difference between the study eyes and the fellow eyes was statistically significant (P < 0.0001, Student's t test). The cumulative incidence of adverse events was 58.5% by week 12. Ocular itching was the most frequently observed adverse event (29.3%). All adverse events were clinically tolerable.. Tafluprost induced significant IOP reductions in NTG patients with a baseline IOP of 16 mmHg or less without raising any safety concerns.
