Cathodal (-) iontophoresis of 9-beta-D-arabinofuranosyl-adenine 5'-monophosphate (vidarabine monophosphate; Ara-AMP) was performed once daily for 3 days for the treatment of experimental herpes simplex virus type 1 (HSV-1) keratitis in rabbit eyes, and the therapeutic efficacy was compared with that of topical treatment of Ara-AMP and idoxuridine (IDU) administered five times daily for 4 days. With the treatment initiated 24 hr after viral inoculation, Ara-AMP cathodal iontophoresis resulted in significant suppression of epithelial and anterior segment disease processes. Topical IDU (0.5%) or Ara-AMP (10%) also significantly improved the disease process when compared to the placebo-treated group; however, iontophoresis of Ara-AMP resulted in a more marked improvement. Slit-lamp examination indicated that iontophoresis did not cause any observable pathologic changes in corneal epithelium, stroma, conjunctiva, or iris of rabbit eyes. This experiment suggests that iontophoresis of Ara-AMP is a safe and effective approach for preventing the development of herpes simplex keratitis in rabbits.

Adenine arabinoside monophosphate (Ara-AMP) demonstrated antiviral activity equivalent to adenine arabinoside (Ara-A) against herpesvirus Types 1 and 2 in tissue culture. Against established herpes virus Type 1 epithelial keratitis in rabbits, Ara-AMP 2 per cent was comparable in efficacy to Ara-A 3 per cent, and Ara-AMP 20 per cent was superior to Ara-A 3 per cent. These results are especially significant in that Ara-A's high solubility will permit (1) more concentrated formulations to be presented topically and (2) adequate absorption by parenteral routes with smaller fluid loads than required for Ara-A.
