Documented Uses

• A number of prescription loteprednol etabonate ophthalmic products are specifically indicated for the treatment of post-operative inflammation and pain following ocular surgery.
• Agents that are used to treat allergic reactions. Most of these drugs act by preventing the release of inflammatory mediators or inhibiting the actions of released mediators on their target cells. (From AMA Drug Evaluations Annual, 1994, p475)
• Corticosteroid Hormone Receptor Agonists [MoA]; Corticosteroid [EPC]
• Loteprednol etabonate (LE) demonstrates good ocular permeation properties as it is lipid soluble, allowing the agent to penetrate into cells with relative ease. Results from the ocular administration of loteprednol in normal, healthy volunteers have shown that there are low or undetectable concentrations of either unchanged material or its metabolite. Following twice-daily unilateral topical ocular dosing of LE for 14 days in healthy subjects, the plasma concentrations of loteprednol etabonate were below the limit
• Following systemic administration to rats, loteprednol etabonate is eliminated primarily via the biliary/faecal route, with most of the dose eliminated in the form of the metabolite, PJ-90.
• The only data available regarding the volume of distribution of loteprednol etabonate (LE) is the volume of distribution the agent demonstrated when administered to dogs - a value of 3.7 L/kg. It has been shown, however, that the topical ocular administration of LE distributes preferentially into the cellular components of blood.
