At present, there is no drug marketed in the United States for the treatment of herpes simplex, except for idoxuridine for the treatment of herpetic keratitis. The recent enthusiasm for the use of heterocyclice fluorescent dyes in conjunction with exposure to light (photodynamic inactivation) has diminished, and the efficacy of all available topical measures is being questioned. Of the numerous antiviral drugs being investigated, the following seem to show promise: idoxuridine, adenin arabinoside, trifluorothymidine, phosphonoacetic acid, and ribavirin. There are no vaccines available. Measures to stimulate immune response concern the use of levamisole hydrochloride, Interferon, Inosiplex and Transfer factor. Only adenine arabinoside will be available in the near future, and then only to serious life threatening infections. The marketing of other medications is several years in the future.

In the rabbit 5% phosphonoacetic acid ointment suppressed herpetic keratitis as well as 0-5% idoxuridine ointment. After 5 days of treatment quantitative virus titres showed that phosphonoacetic acid was superior to idoxuridine in the inhibition of herpes virus replication. Phosphonoacetic acid was found to be nontoxic to the eye in both clinical and histopathological studies. Recent reports suggest that the mechanism of action of phosphonoacetic acid appears to be the blocking of the virus DNA polymerase, which is essential for the synthesis of herpes virus DNA.

Phosphonoacetic acid had a significant antiviral effect when applied topically, both in liquid and ointment preparations, on superficial herpetic keratitis in rabbits and was equally as effective as idoxuridine. It was also effective in the treatment of idoxuridine-resistant herpetic keratitis. Phosphonoacetic acid was not effective in the treatment of experimental herpetic iritis when applied topically but was significantly effective when administered intravenously and subconjunctivally. No significant local or systemic toxicity was encountered.
