  • Title: Treatment of primary acute genital herpes in guinea pigs by intraperitoneal administration of fluoropyrimidines.
    Author: Mayo DR, Hsiung GD.
    Journal: Antimicrob Agents Chemother; 1984 Sep; 26(3):354-7. PubMed ID: 6239591.
    Abstract:
    FIAC [1-(2'-deoxy-2'-fluoro-beta-D-arabinofuranosyl)-5-iodocytosine], FIAU [1-(2'-deoxy-2'-fluoro-beta-D-arabinofuranosyl)-5-iodouracil], and FMAU [1-(2'-deoxy-2'-fluoro-beta-D-arabinofuranosyl)-5-methyluracil] were evaluated for their efficacies in the treatment of genital infections with herpes simplex virus type 2 in guinea pigs. Intraperitoneal administration of these drugs in daily doses of 100 mg/kg of body weight initiated 24 h after virus inoculation and repeated 2 successive days thereafter inhibited development of genital lesions and reduced shedding of virus without evoking untoward reactions. In a comparative study with this 3-day dosage schedule, the efficacy of daily doses of 50 mg of FMAU per kg was greater than that of the same doses of FIAC and FIAU, in that order; all these were more effective than daily doses of 50, 100, or 200 mg of acyclovir or of 500 mg of phosphonoformic acid per kg. These differences in efficacy were enhanced when treatment was delayed for 2 to 3 days after inoculation.
