A patient preference comparison of Azarga (brinzolamide/timolol fixed combination) vs Cosopt (dorzolamide/timolol fixed combination) in patients with open-angle glaucoma or ocular hypertension.

Purpose: To determine patient preference of and ocular discomfort with fixed combination brinzolamide/timolol compared with fixed combination dorzolamide/timolol.

Methods: In a prospective, double-masked, randomized, active-controlled, crossover, multicenter study, patients received 1 drop of brinzolamide/timolol and dorzolamide/timolol in both eyes on consecutive days in random order. Ocular discomfort was rated 1 minute after instillation of each medication, and preference was noted on Day 2.

Analgesic and anti-inflammatory effectiveness of nepafenac 0.1% for cataract surgery.

Background: To compare nepafenac 0.1% with placebo and ketorolac 0.5% for prevention and treatment of ocular pain and inflammation after cataract surgery.

Prophylactic effectiveness of tobramycin-dexamethasone eye drops compared with tobramycin/vehicle eye drops in controlling post-surgical inflammation in cataract patients : prospective, randomised, double-masked, two-arm, parallel-group, placebo-controlled, multicentre study.

Objective: To demonstrate the superiority of TobraDex((R)) (tobramycin 3 mg/mL, dexamethasone 1 mg/mL) eye drops over Tobrex((R)) (tobramycin 3 mg/mL)/vehicle (placebo) eye drops in the prophylaxis of inflammation after cataract surgery, and to provide additional safety data on TobraDex((R)).

Setting: Twenty-two ophthalmology clinics from Brazil, Belgium, Germany, Ireland, Portugal, Spain and Sweden.

Patients And Methods: Prospective, randomised, double-masked, two-arm, parallel-group, placebo-controlled, multicentre study in 417 patients undergoing extracapsular cataract extraction with intraocular lens implantation.

Comparison of topical tobramycin-dexamethasone with dexamethasone-neomycin-polymyxin and neomycin-polymyxin-gramicidin for control of inflammation after cataract surgery: results of a multicenter, prospective, three-arm, randomized, double-masked, controlled, parallel-group study.

Background: Intraocular inflammation is typically treated with a combination of anti-inflammatory and anti-infective drugs. Tobramycin-dexamethasone (TD) has not been associated with any serious adverse events, indicating good tolerability.

Objective: The aims of this study were the following: (1) to demonstrate noninferiority of TD compared with dexamethasone-neomycin-polymyxin (DNP) in terms of anti-inflammatory efficacy, (2) to compare the anti-inflammatory efficacy of TD and DNP with that of a "placebo" control (antibiotic without anti-inflammatory agent), and (3) to provide additional safety data on TD.

Tolerability and safety of 0.1% diclofenac plus 0.3% tobramycin fixed-dose ophthalmic solution: a randomized, comparative, controlled study in healthy volunteers.

The purpose of this double-blind, observer-masked, randomized, crossover trial was to compare the tolerability and safety of a fixed-dose ophthalmic solution of 0.3% tobramycin plus 0.1% diclofenac versus Tobrex (tobramycin sulfate ophth) and Voltaren (diclofenac sodium).

Gastric tone determines the sensitivity of the stomach to distention.

Background/aims: Whether meal-related symptoms such as postcibal epigastric fullness and discomfort are caused by hypotonic gastric expansion or gastric hypertension is unknown. This study investigated whether symptoms in healthy individuals in response to gastric distention are produced by gastric expansion or by an increase in intragastric pressure.

Methods: Increasing gastric distentions (for 5 minutes at 5-minute intervals) at fixed pressure levels (in 2-mm Hg increments) and at fixed volume levels (in 200-mL increments) were performed in 10 healthy subjects per group; perception was measured on a 0-6 scale.

Treatment of chronic nonbacterial conjunctivitis with a cyclo-oxygenase inhibitor or a corticosteroid. Pranoprofen Study Group.

A multicenter, double-masked, parallel-group clinical trial was carried out in 151 patients with moderate to severe chronic conjunctivitis. The study compared the antiinflammatory efficacy and safety of pranoprofen 0.1%, a new cyclo-oxygenase inhibitor, with fluorometholone 0.

Gastric emptying in marathon runners.

Radionuclide gastric emptying studies using 99m-Tc human serum albumin egg omelette have been carried out in 10 long distance runners at rest and during a 90 minute run at sustained speed. Resting values are compared with controls comprising 10 sedentary subjects. Runners show a significantly accelerated basal gastric emptying (runners t 1/2 = 67.

The use of gastric ultrasonography in the evaluation of a new antiflatulent preparation in human volunteers.

A method is described for inducing experimental aerogastria (flatulence) in human volunteers by the ingestion of "whipped" egg-white. Abdominal ultrasonography was used to measure the distension of the stomach and its interference with the visualization of organs such as gall bladder, pancreas and left kidney lying behind the stomach. A double-blind crossover comparison of Flatoril, a mixture of dimethicone (200 mg) and clebopride (0.

Gastric emptying of solid and liquid meals in healthy young subjects.

Gastric emptying was measured in 50 young healthy subjects by means of sequential scintigraphy with two radioactive markers. Gastric emptying of the solid component of the meal was slower than that of the liquid component, corresponding to a linear model (T 1/2, 112 min). Gastric emptying of the liquid component was different, following an exponential model, although only after 45 min (100% of the liquid marker retained in the stomach after 15 min, 56.
