Intraocular penetration of new antiviral agent, hydroxyacyclovir (BW-B759U).
9-[(2-hydroxyl-1-(hydroxymethyl)ethoxy]methyl)guanine (hydroxyacyclovir) is a nucleoside analogue with a high degree of efficacy against herpes simplex virus types 1 and 2 and cytomegalovirus (CMV). This antiviral agent demonstrates a low toxicity towards uninfected cells. Intraocular levels in rabbits were evaluated following subconjunctival, intravenous, intravitreal and topical administration. Retinal toxicity studies were performed. Hydroxyacyclovir may have applications in the treatment of deep herpetic infections, CMV retinitis, and acute retinal necrosis.
