Oral drug effective for treatment of CMV retinitis
NUTLEY, N.J. An oral treatment for cytomegalovirus retinitis is as effective as the standard intravenous treatment, according to a study published in The New England Journal of Medicine.
Availability of an oral agent for treatment of the opportunistic infection may offer patients more convenience and avoid the problems and costs associated with IV administration frequent hospitalization and a chronic indwelling catheter according to the drugs manufacturer, based here.
Researchers compared Valcyte tablets (valganciclovir, Roche) to intravenous Cytovene (ganciclovir, Roche) as induction therapy for newly-diagnosed cytomegalovirus (CMV) retinitis in 160 patients with AIDS. Patients were randomized to either oral valganciclovir or IV ganciclovir.
During the first 4 weeks, 64 of 71 patients on valganciclovir did not experience progression of CMV retinitis as measured by retinal photography. In the ganciclovir group, 63 of 70 patients did not experience any CMV retinitis progression.
Common adverse events included diarrhea, which occurred in 19% of the valganciclovir group and 10% of the ganciclovir group. The frequency and severity of adverse events were similar in the two groups.
