NCT00669799 ↗	Topical Antibiotic Use In Chronic Rhinosinusitis A Double-Blinded, Randomized, Placebo Controlled Study	Withdrawn	University of South Florida	N/A	2008-03-01	Chronic rhinosinusitis is a pervasive and costly disease. Recent estimates describe over 20 million Americans suffering from this diagnosis at a cost of over $4.3 billion per year. Primary intervention consists of oral antibiotics and nasal steroid sprays. A role for antifungal irrigation has also been proposed. Topical antibiotics are used by some physicians, but there are few reports in the published literature describing their use and establishing or refuting their efficacy. Sykes in 1986 performed a randomized, prospective, double-blinded study with 50 patients using topical nasal sprays with dexamethasone, tramazoline, and neomycin; dexamethasone and tramazoline without antimicrobial; and placebo. Both of the treatment groups showed improvement over placebo, but in those groups there was no significant difference in response rates between those patients receiving neomycin and those who did not. There were no adverse events reported. In the same year, Cuenant et al. reported success with neomycin-tixocortol irrigations in the treatment of chronic rhinosinusitis. Scheinberg and Otsuji and Vaughn and Carvalho describe their use of various nebulized antimicrobials (including aminoglycosides) in patients with recurrent sinusitis. Both are uncontrolled, retrospective studies showing improvement in symptom scores. Neither study reported any major side effects. Leonard and Bolger describe a case report and review their success with the use of topical Ceftazidime in 50 patients. Only one patient reported stinging sensation during administration. They reported no problems with antibiotic resistance. Studies by Davidson et al. , and Moss and King describe the use of topical antibiotics for sinusitis in patients with cystic fibrosis. They report improvement in sinusitis symptoms and reduction of need for revision sinus surgery in patients treated with surgery followed by topical intranasal tobramycin. They report no significant side effects. Dudley described the use of topical gentamicin in a case report of a patient with atrophic rhinitis. The patient had resolution of her complaints without any adverse symptoms. He also describes a study by Thornell showing success with streptomycin nasal sprays and reports work by Rubinstein demonstrating safe administration of gentamicin into the nose without absorption by the nasal mucosa. On balance, the literature describes topical antibiotics as a safe, but variably efficacious treatment for chronic rhinosinusitis. There is a paucity of prospective, randomized, blinded, and controlled studies. The purpose of this protocol is to describe a scientifically rigorous study of the use of broad spectrum antibiotic nasal sprays for chronic sinusitis. The patient population for this study will consist of patients who have a history of multiple sinus infections each year that require treatment with antibiotics. The patients in this study will have had recurrent infections despite prior medical and surgical intervention. They will fulfill the criteria for chronic rhinosinusitis without nasal polyposis. Treatment will include conventional treatment with oral antibiotics and a topical nasal steroid. In addition, patients will be randomized to receive either topical antibiotics or a vehicle placebo. The study will follow patients for a three month period. Patients will be monitored for improvement in radiographic findings and quality of life when compared to a randomized and double-blinded placebo group. The patient population identified for inclusion in this study will also be evaluated for allergy and humoral and innate immunodeficiency. Nasal lavage will be obtained from the study population and pre and post-treatment comparisons will be performed.
NCT00695435 ↗	Tobramycin Tear Concentrations	Completed	Alcon Research	Phase 1	2008-06-01	To evaluate the Tobramycin tear concentration values of TOBRADEX® Ophthalmic Suspension, Tobramycin 0.3% / Dexamethasone 0.05% Ophthalmic Suspension versus TOBREX® Ophthalmic Solution in normal volunteers.
NCT00992355 ↗	Tobramycin-Dexamethasone Versus Tobramycin-Dexamethasone Plus Ketorolac After Phacoemulsification Surgery	Completed	Veroia General Hospital	N/A	2009-01-01	This randomized controlled trial compares two regimens of topical therapy: - tobramycin 0.3% - dexamethasone 0.1% (TobraDex®, Alcon), one drop four times/day - combination of tobramycin 0.3% - dexamethasone 0.1% (TobraDex®, Alcon), one drop four times/day, plus Ketorolac tromethamine 0.5% (Acular®, Allergan), one drop three times/day. The topical treatment is administered for 28 days after phacoemulsification. Patients are independently assessed by two ophthalmologists. On day 28, patients are evaluated for - corneal edema - conjunctival redness - anterior chamber reaction. Moreover, the cases necessitating continuation of treatment are compared in the two groups on day 28 and 42.
NCT01028027 ↗	Loteprednol and Tobramycin Versus Tobramycin and Dexamethasone, in the Treatment of Blepharokeratoconjunctivitis	Completed	Bausch & Lomb Incorporated	Phase 3	2009-10-01	This study is to evaluate the safety and efficacy of loteprednol etabonate [LE] and tobramycin ophthalmic suspension versus tobramycin and dexamethasone ophthalmic suspension in the treatment of ocular inflammation associated with blepharokeratoconjunctivitis (BKC).

Tobramycin and Dexamethasone: Clinical Trials, Market Analysis, and Projections

Introduction to Tobramycin and Dexamethasone

Tobramycin and dexamethasone are commonly combined in ophthalmic formulations to treat bacterial eye infections and associated inflammation. This combination has been extensively studied and is widely used in clinical practice.

Clinical Efficacy and Safety

Clinical Trials Overview

A key clinical trial comparing the efficacy and safety of tobramycin/dexamethasone (TobraDex ST) with azithromycin in treating moderate to severe blepharitis/blepharoconjunctivitis highlighted the superior performance of the tobramycin/dexamethasone combination. This multicenter, randomized, investigator-masked study involved 122 adult subjects and demonstrated that the tobramycin/dexamethasone group had a statistically significant lower mean global score for signs and symptoms at Day 8 compared to the azithromycin group[1].

Treatment Outcomes

The combination of tobramycin and dexamethasone has been shown to provide faster inflammation relief and more effective treatment of bacterial conjunctivitis and blepharitis. Tobramycin acts by depleting the bacterial membrane and inhibiting protein synthesis, while dexamethasone suppresses inflammatory responses, providing symptomatic relief from redness, irritation, and itching[3].

Safety Profile

No serious adverse events were reported in the clinical trial comparing tobramycin/dexamethasone with azithromycin, indicating a safe profile for this combination[1].
