The Safety and Effectiveness of Valacyclovir HCl in the Treatment of Herpes Simplex or Varicella/Zoster Infections in HIV-1 Infected Children
0
Plain-language summary
To obtain tolerance, safety, and pharmacokinetic data for oral valacyclovir hydrochloride ( 256U87 ) in HIV-1 infected children with herpes simplex virus infections ( cold sores ) and/or varicella / zoster virus infections ( chicken pox / shingles ).
Varicella and zoster are common problems in HIV-infected children. It is believed that chronic oral therapy with acyclovir may result in subtherapeutic concentrations of acyclovir, resulting in resistance to that drug. Valacyclovir hydrochloride, which converts to acyclovir in the body, increases acyclovir bioavailability by 3-5 fold.
