Ocular reaction to timolol maleate.
A patient prescribed timolol maleate for the control of hypertension developed dryness of the eyes. The symptoms improved on withdrawal of the drug. Vigilance for such adverse reactions must be observed in the use of any beta-adrenoreceptor blocking agent.
متن کاملPlasma levels and systemic safety of 0.1% unpreserved timolol maleate gel, 0.5% timolol aqueous solution and 0.5% timolol maleate gel.
PURPOSE To compare systemic absorption of three formulations of timolol eye drops: 0.1% timolol maleate gel, 0.5% timolol aqueous solution, and 0.5% timolol maleate gel. METHODS This was a double cross-over phase I study. Cross-over 1: two weeks of 0.1% timolol gel once daily, followed by a 3-week wash-out period and then two weeks of 0.5% timolol aqueous solution twice a day (group 1) or the...
متن کاملIn vitro and in vivo evaluation of Pluronic F127-based ocular delivery system for timolol maleate.
The purpose of this study was to develop Pluronic F127 (PF127) based formulations of timolol maleate (TM) aimed at enhancing its ocular bioavailability. The effect of isotonicity agents and PF127 concentrations on the rheological properties of the prepared formulations was examined. In an attempt to reduce the concentration of PF127 without compromising the in situ gelling capabilities, various...
متن کاملProducing Gelatin Nanoparticles as Delivery System for Bovine Serum Albumin
Background: Progress in the field of biology and biochemistry has led to the discovery of numerous bioactive peptides and proteins in the last few decades. Delivery of therapeutic proteins/peptides has received a considerable amount of attention in recent years. Methods: In this study, a two-step desolvation method was used to produce biodegradable hydrophilic gelatin nanoparticles (GNP) as a d...
متن کاملSafety and efficacy of switching from dorzolamide 1.0%/timolol maleate 0.5% eye drops to brinzolamide 1.0%/timolol maleate 0.5% eye drops
PURPOSE To evaluate the safety and efficacy of switching from dorzolamide 1.0%/timolol maleate 0.5% fixed-combination (DTFC) eye drops to brinzolamide 1.0%/timolol maleate 0.5% fixed-combination (BTFC) eye drops in patients with primary open-angle glaucoma or ocular hypertension. METHODS A total of 35 eyes of 35 patients with primary open-angle glaucoma or ocular hypertension using DTFC eye d...
