Zylet (loteprednol etabonate and tobramycin ophthalmic suspension), is a sterile, multiple dose topical anti-inflammatory corticosteroid and antibiotic combination for ophthalmic use.
Zylet is indicated for steroid-responsive inflammatory ocular conditions for which a corticosteroid is indicated and where superficial bacterial ocular infection or a risk of bacterial ocular infection exists.
Ocular steroids are indicated in inflammatory conditions of the palpebral and bulbar conjunctiva, cornea and anterior segment of the globe such as allergic conjunctivitis, acne rosacea, superficial punctate keratitis, herpes zoster keratitis, iritis, cyclitis, and where the inherent risk of steroid use in certain infective conjunctivitides is accepted to obtain a diminution in edema and inflammation. They are also indicated in chronic anterior uveitis and corneal injury from chemical, radiation or thermal burns, or penetration of foreign bodies.
The use of a combination drug with an anti-infective component is indicated where the risk of superficial ocular infection is high or where there is an expectation that potentially dangerous numbers of bacteria will be present in the eye.
The particular anti-infective drug in this product (tobramycin) is active against the following common bacterial eye pathogens: Staphylococci, including S. aureus and S. epidermidis (coagulase-positive and coagulase-negative), including penicillin-resistant strains. Streptococci, including some of the Group A-beta-hemolytic species, some nonhemolytic species, and some Streptococcus pneumoniae. Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, Enterobacter aerogenes, Proteus mirabilis, Morganella morganii, most Proteus vulgaris strains , Haemophilus influenzae, and H. aegyptius, Moraxella lacunata, Acinetobacter calcoaceticus and some Neisseria species.

Clinical Trials Related to Zylet (Loteprednol / Tobramycin)
Efficacy of Zylet vs. Lotemax for the Treatment of Ocular Surface Inflammation/MGD/Blepharitis [Active, not recruiting]
This is a Phase IV, single site, randomized, double masked, parallel control clinical trial
of 60 subjects to investigate the variance of efficacy between Lotemax® and Zylet® for
treatment of ocular surface inflammation due to meibomian gland dysfunction (MGD). Efficacy
will be measured by in-vivo confocal microscopy, corneal fluorescein staining, grading of
meibomian gland dysfunction and validated ocular symptom assessment questionnaire.
Safety and Efficacy of Zylet vs Lotemax, Tobramycin and Vehicle in Pediatric Blepharoconjunctivitis [Completed]
The objective of this study is to evaluate the safety and effectiveness of Zylet in
comparison with Lotemax, Tobramycin and the vehicle of Zylet for the treatment of
blepharoconjunctivitis in pediatric subjects.
Ocular Tolerance and Intraocular Pressure (IOP) Effects of Zylet Versus Tobradex [Completed]
Phase IV, randomized, double-masked, parallel-group clinical trial comparing the ocular
tolerability and steroid-induced intraocular pressure (IOP) effects of Zylet wth that of
TobraDex in healthy volunteers, when either product was administered QID (at approximately
4-hour intervals) for 28 days.
