Study summary

The purpose of this study is to evaluate the penetration of levofloxacin and dexamethasone 21-phosphate into the aqueous humour after ocular administration in combination or as single active ingredients.

Read the detailed description

In most cases, postoperative care after cataract surgery consists of antiinflammatory and antibacterial drug therapy. The use of an ophthalmic solution containing the combination of a steroid and an antibiotic is routinely used in clinical practice; however, treatment duration could favour the emergence of antibiotic resistance. The study treatment associating a broad-spectrum antibiotic with a highly effective corticosteroid that can be used for a short period of time (one week) is therefore of considerable interest.

The aim of this study is to measure the concentrations of levofloxacin and dexamethasone in the aqueous humour after topical application of the combined ophthalmic solution and its single components.
