Intraocular penetration of topically applied lincomycin hydrochloride in rabbits. 1979

J Kleinberg, and F J Dea, and J A Anderson, and I H Leopold

Ocular penetration of lincomycin hydrochloride in albino rabbits was determined by bioassay. On topical application, the frequency of multiple instillation of drops played an important role in producing therapeutic levels in the anterior chambers. Therapeutic levels were attained in the cornea, aqueous humor, and iris-ciliary body, with peak values occurring at 30 to 45 minutes. Varying the pH of the dosing solution did not change ocular absorption and distribution substantially. Removal of corneal epithelium, however, greatly enhanced absorption. Relative to clindamycin, lincomycin hydrochloride had longer onset of peak values and lower overall concentration in ocular tissues. Intravitreous injection of lincomycin hydrochloride produced therapeutic and steady levels of antibiotic in anterior chambers. Injection produced a concentration in aqueous humor twice that achievable topically. The major route of elimination from the posterior chamber was through retina-choroid.

D000287	Administration, Topical	The application of drug preparations to the surfaces of the body, especially the skin (ADMINISTRATION, CUTANEOUS) or mucous membranes. This method of treatment is used to avoid systemic side effects when high doses are required at a localized area or as an alternative systemic administration route, to avoid hepatic processing for example.
