[The latest developments in glaucoma therapy using fixed combination products].
Modern fixed-combination products simplify medication dose regimen without sacrificing their effectiveness.Potential benefits of the therapy with fixed-combination products are enhanced tolerability increased convenience,better compliance,cost and time economy and removal of the wash out effect. Regarding intraocular pressure lowering effect, fixed-combination agents are superior to monotherapy with the two medication components, with the exception of Duotrav that is not superior to travoprost action.Fixed-combination products are noninferior to concomitant administration of the two components of medication (nonfixed-combination agents) relative to their ocular hypotensive efficacy with the exception of Ganfort that is however inferior to concurrent administration of both the bimatoprost and timolol.

Fixed Combination of Travoprost and Timolol Maleate Reduces Intraocular Pressure in Japanese Patients with Primary Open-Angle Glaucoma or Ocular Hypertension: A Prospective Multicenter Open-Label Study.
The efficacy of lowering intraocular pressure (IOP) and safety of switching to travoprost/timolol fixed combination ophthalmic solution (Duotrav(®), Alcon Laboratories, Inc., Fort Worth, TX, USA) in patients with primary open-angle glaucoma, normal tension glaucoma or ocular hypertension undergoing prostaglandin analog (PGA) monotherapy was investigated.. Patients treated with travoprost, latanoprost, tafluprost, or bimatoprost for ≥3 months and requiring additional medication were switched to Duotrav without washout. Baseline IOP was calculated from measurements at two visits during PGA monotherapy. IOP reductions at 4, 8, and 12 weeks after switching to Duotrav and adverse events were assessed.. Of 162 patients enrolled, 157 patients (96.9%) with ≥4 weeks of follow-up after switching to Duotrav were analyzed. The mean IOP decreased significantly (baseline = 16.3 ± 3.1 mmHg; 4 weeks = 14.6 ± 3.1 mmHg, 8 weeks = 14.7 ± 3.3 mmHg, 12 weeks = 14.6 ± 3.2 mmHg; all P < 0.0001). When study eyes were divided into three groups according to baseline IOP (≥19 mmHg: 33 eyes, 21.0%; ≥15 to <19 mmHg: 78 eyes, 49.7%; <15 mmHg: 46 eyes, 29.3%), all groups showed significant IOP reductions (P = 0.0324 ~ P < 0.0001) after switching to Duotrav. Twenty-seven of 166 patients (16.3%) in the safety analysis experienced adverse events and 26/166 patients (15.7%) experienced adverse events, for which a relationship to Duotrav could not be ruled out. Adverse events in five patients led to treatment discontinuation (eye pruritus; eye irritation; increased blood pressure and rash; increased blurred vision; deepening of the eyelid sulcus and blepharoptosis). Twelve weeks after treatment switching, eyelash changes, blepharal pigmentation and deepening of the eyelid sulcus occurred in 42 (26.8%), 29 (18.5%), and 13 (8.3%) cases, respectively, among 157 patients with follow-up. There was no significant worsening from baseline for superficial punctate keratopathy (SPK) or conjunctival hyperemia after switching (SPK score: baseline = 0.58 ± 1.31; 12 weeks = 0.92 ± 1.76, P = 0.1819; conjunctival hyperemia score: baseline = 0.41 ± 0.64; 12 weeks = 0.49 ± 0.63, P = 0.3774).. Our findings confirm that switching to Duotrav(®) in PGA monotherapy patients shows IOP-lowering effect with minimal safety concerns.. Japan Association of Health Service and Alcon Japan. Ltd..

The transcorneal penetration of commercial ophthalmic formulations containing timolol maleate in rabbit eyes.
We investigated the transcorneal penetration of commercial ophthalmic formulations containing timolol maleate in rabbit eyes.. One drop (30 μL) of each ophthalmic solution (Xalacom(®), DuoTrav(®), Cosopt(®), and Timoptol(®)) was administered to the conjunctival sac of the rabbits' eyes and the timolol maleate aqueous humor concentration was measured by high-performance liquid chromatography 15, 60, 120, and 240 min after the completion of administration. The effect of timolol ophthalmic solution pH (5.7-6.8) on ocular penetration was also examined.. The concentration [Cmax (μg/mL)] of timolol maleate, found in each of the 4 ophthalmic solutions, penetrated to the aqueous humor was as follows: DuoTrav>Cosopt>Timoptol>Xalacom. The concentration of timolol maleate penetrated to the aqueous humor was highest with solutions in the vicinity of pH 6.8.. The concentration of timolol maleate penetrated to the aqueous humor was highest in DuoTrav followed by Cosopt, Timoptol, and Xalacom, and the pH and Benzalkonium chloride (BAK) concentration of the ophthalmic solution were believed to be factors that influenced this phenomena.
