A review of topical and intralesional cidofovir.
Cidofovir is a potent nucleoside analog antiviral drug approved for the treatment of cytomegalovirus (CMV) retinitis in patients with the Acquired Immune Deficiency Syndrome (AIDS). It is currently available only for intravenous infusion. Several small studies and case reports describe the successful use of cidofovir applied either topically or by intralesional injection in several virally induced cutaneous diseases. Available information demonstrates that cidofovir is a potent antiviral agent with activity against several DNA viruses that cause cutaneous disease when applied topically or administered by intralesional injection. No significant systemic side effects have been noted, although application site reactions are common and can occasionally be severe. The effective use of topical and intralesional cidofovir for the treatment of diseases of the skin caused by DNA viruses has been demonstrated in animals and a limited number of patients including those infected with human immunodeficiency virus (HIV). This article reviews the pharmacology of cidofovir and the utility of topical and intralesional cidofovir for the treatment of viral infections caused by human papillomavirus, herpesviruses (including acyclovir resistant strains), Kaposi's sarcoma-associated herpesvirus, molluscum contagiosum and monkeypox.
