Thymine arabinoside (Ara-T) topical and iontophoretic application for herpes simplex virus type 1 and type 2 skin infections in hairless mice. 1984

J M Hill, and C A Wiggins, and B S Kwon, and G A Gentry, and L P Gangarosa

The antiviral agent thymine arabinoside (9-beta-D-arabinofuranosyl thymine, Ara-T) was applied topically and by anodal (+) iontophoresis in a NaCl solution to Herpes simplex virus type 1 (HSV-1), and Herpes simplex virus type 2 (HSV-2) skin infections in hairless mice. The chemotherapeutic efficacy of Ara-T was evaluated employing the parameters of mean lesion score, number of mice with signs of neurological involvement (paralysis), mortality and mean survival time. Anodal (+) iontophoresis of 0.4% Ara-T in a 0.1 M NaCl solution significantly suppressed HSV-1 skin infection, but the infection was not altered by topical application of 3% Ara-T. HSV-2 infection was refractory to both topical and iontophoretic application of Ara-T. This is the first report of the in vivo efficacy of Ara-T for HSV-1 skin infections.

UI	MeSH Term	Description	Entries
D007478	Iontophoresis	Therapeutic introduction of ions of soluble salts into tissues by means of electric current. In medical literature it is commonly used to indicate the process of increasing the penetration of drugs into surface tissues by the application of electric current. It has nothing to do with ION EXCHANGE; AIR IONIZATION nor PHONOPHORESIS, none of which requires current.	Iontophoreses

D006561	Herpes Simplex	A group of acute infections caused by herpes simplex virus type 1 or type 2 that is characterized by the development of one or more small fluid-filled vesicles with a raised erythematous base on the skin or mucous membrane. It occurs as a primary infection or recurs due to a reactivation of a latent infection. (Dorland, 27th ed.)	Herpes Simplex Virus Infection
D000287	Administration, Topical	The application of drug preparations to the surfaces of the body, especially the skin (ADMINISTRATION, CUTANEOUS) or mucous membranes. This method of treatment is used to avoid systemic side effects when high doses are required at a localized area or as an alternative systemic administration route, to avoid hepatic processing for example.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000998	Antiviral Agents	Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly.
