Ophthalmic ointments.

Abstract

The use of ointments as an ocular drug vehicle adds an important dimension to topical therapy. Ointments are well tolerated, fairly safe, and provide an excellent means for enhanced ocular contact time. In the case of certain antibiotics, this improved contact time yields increased ocular drug levels. However, experimental data indicate that corticosteroid ointments do not penetrate into the eye as well as do suspension preparations. This may relate to the binding of the drug to the ointment base and also to the particular steroid compound. Like other ophthalmic preparations, ointments may become contaminated. Ophthalmic ointments should not be instilled into eyes with open wounds. Instillation of ointments into postoperative eyes where wound closure is secure appears to be safe and effective.
