Therapy/Class: Antibiotic + Corticosteroid
Mechanism of Action:
Loteprednol Etabonate: A retrometabolic, ester-based ‘soft’ corticosteroid structurally designed to provide potent localized immunosuppressive and anti-inflammatory effects, followed by predictable, rapid de-esterification into inactive carboxylic acid metabolites. This mechanism dramatically mitigates the propensity for steroid-induced intraocular pressure (IOP) elevation.
Tobramycin: A water-soluble aminoglycoside that irreversibly binds to the 30S subunit of the bacterial ribosome, inducing mRNA misreading. It exhibits excellent bactericidal activity, specifically functioning as a critical clinical tool against severe Gram-negative bacilli keratitis and conjunctivitis.
