Xoviral

• Acute herpetic keratitis (dendritic ulcers)

Ganciclovir is a guanosine derivative that, upon phosphorylation, inhibits DNA replication by herpes simplex viruses (HSV). Ganciclovir is transformed by viral and cellular thymidine kinases (TK) to ganciclovir triphosphate, which acts as an antiviral agent by inhibiting the synthesis of viral DNA in two ways: competitive inhibition of viral DNA-polymerase and direct incorporation into viral primer strand DNA, resulting in DNA chain termination and prevention of DNA replication.

Adult Dose:

• Ganciclovir eye gel 0.15%: 1 drop in the affected eye 5 times per day (approximately every 3 hours while awake) until the corneal ulcer heals.
• Then 1 drop 3 times per day for 7 days.

* Use as directed by the registered physician
