Aqueous humour penetration of moxifloxocin and gatifloxacin eye drops in different dosing regimens before phacoemulsification surgery. [2011.09]
AIM: To compare the aqueous humour penetration of moxifloxacin 0.5% and gatifloxacin 0.3% eye drops administered in two different dosing regimens during phacoemulsification surgery... CONCLUSION: Moxifloxacin, given in the same dosage, penetrated the aqueous humour better then gatifloxacin during cataract surgery. The penetration of both antibiotics increased significantly when the dosage of the agent was doubled.
Human aqueous humor concentrations of besifloxacin, moxifloxacin, and gatifloxacin after topical ocular application. [2011.06]
PURPOSE: To determine the concentrations of besifloxacin, moxifloxacin, and gatifloxacin in human aqueous humor after topical instillation of commercially available besifloxacin ophthalmic suspension 0.6%, moxifloxacin ophthalmic solution 0.5%, and gatifloxacin ophthalmic solution 0.3%, and to assess these concentrations relative to the minimum inhibitory concentration for 90% of strains (MIC(90)) for each drug against bacterial pathogens identified in recent cases of postoperative endophthalmitis. SETTING: Six clinical sites, United States. DESIGN: Randomized open-label controlled clinical trial... CONCLUSIONS: Based on the aqueous humor drug concentrations measured in this study, it is unlikely that any of the fluoroquinolones tested would be therapeutically effective in the aqueous humor against the most frequently identified drug-resistant staphylococcal isolates from recent cases of postoperative endophthalmitis.

A prospective randomized evaluation of topical gatifloxacin on conjunctival flora in patients undergoing intravitreal injections. [2009.08]
PURPOSE: We sought to assess the efficacy of 3-day topical gatifloxacin use in combination with povidone-iodine (PVI) versus PVI alone in eliminating conjunctival bacterial flora in patients scheduled to undergo intravitreal (IVT) injection. DESIGN: Prospective, randomized single-blind clinical trial. PARTICIPANTS: We included 129 patients scheduled to undergo 273 IVT injections at California Vitreoretinal Center at Stanford University... CONCLUSIONS: Although 3-day topical gatifloxacin use is effective in reducing the frequency of conjunctival bacterial growth relative to untreated eyes, antibiotic use confers no additional benefit in combination with PVI than eyes receiving PVI alone. This supports that topical PVI is an effective preinjection monotherapy for infection prophylaxis in the setting of IVT injections.
Aqueous humor penetration of gatifloxacin and moxifloxacin eyedrops given in different concentrations in a wick before cataract surgery. [2008.05]
PURPOSE: To determine whether the penetration into the aqueous humor of gatifloxacin (Zymar) and moxifloxacin (Vigamox) eyedrops was affected by altering their concentrations in the dilating mixture in which the wick used to dilate the pupil before cataract surgery was soaked. SETTING: Pasqua Hospital, Regina, Saskatchewan, Canada... CONCLUSIONS: Moxifloxacin penetrated the aqueous humor better than gatifloxacin when given in a wick soaked in the dilating mixture before cataract surgery. Only the penetration of moxifloxacin increased significantly when the volume of the antibiotic in the dilating mixture was doubled. In both groups, only moxifloxacin reached and exceeded the minimum inhibitory concentration levels for the most common ocular pathogens causing endophthalmitis.
Ocular Penetration and Pharmacokinetics of Topical Gatifloxacin 0.3% and Moxifloxacin 0.5% Ophthalmic Solutions After Keratoplasty. [2008.04]
PURPOSE:: To compare the corneal and aqueous penetration and pharmacokinetics of gatifloxacin 0.3% and moxifloxacin 0.5% ophthalmic solutions and their effect on corneal reepithelialization after penetrating keratoplasty... CONCLUSIONS:: Topical preoperative moxifloxacin 0.5% achieved greater corneal and aqueous penetration than did gatifloxacin 0.3%. The clinical significance of this difference is not known. Postoperative use of these agents had similar effects on corneal reepithelialization.
Clinical Trials Related to Zymaxid (Gatifloxacin Ophthalmic)
Effect of Moxifloxacin Versus Gatifloxacin on Corneal Epithelium Following Pterygium Excision [Not yet recruiting]
The purpose of this study is to determine whether there is a difference in corneal
epithelial healing rate and/or toxicity following pterygium excision, between eyes treated
post-operatively by moxifloxacin(VIGAMOX)versus gatifloxacin (ZYMAR).
Gatifloxacin Versus Ceftriaxone in the Treatment of Enteric Fever [Recruiting]
The investigators aim to compare two antibiotic treatments for enteric (typhoid) fever.
Three hundred patients at Patan Hospital will be enrolled in the study. Patients will be
assigned to one of the two treatments by chance and followed for 6 months. The two
treatment groups will be compared to see which treatment is more likely to make the patient
Prospective Randomized Comparison of Zymar(Gatifloxacin) and Vigamox (Moxifloxacin) in Killing Conjunctival Bacterial Flora Following a One-Hour Application [Recruiting]
Topical ophthalmic antibiotics are common prescribed just prior to eye surgery to lower the
risk of infection. Previous studies have suggested that antibiotics containing a
preservative (Zymar) kill bacteria much quicker than those without a preservative (Vigamox).
The purpose of this research is to compare how quickly to the two commonly prescribed
antibiotics eliminate bacteria from the eye surface.
Besifloxacin Ophthalmic Suspension Verses Gatifloxacin Ophthalmic Solution in Neonates With Bacterial Conjunctivitis [Recruiting]
The objective of this study is to evaluate the safety and efficacy of Besivance
(besifloxacin 0. 6%) ophthalmic suspension compared to gatifloxacin 0. 3% ophthalmic solution
when administered three times daily (TID) for seven days to neonatal subjects who are 31
days or younger on the day of randomization (Visit 1).
