The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Varicella and zoster are common problems in HIV-infected children. Listing a study does not mean it has been evaluated by the U. It is believed that chronic oral therapy with acyclovir may result in subtherapeutic concentrations of acyclovir, resulting in resistance to that drug. 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 ). Valacyclovir hydrochloride, which converts to acyclovir in the body, increases acyclovir bioavailability by 3-5 fold. Varicella and zoster are common problems in HIV-infected children.

Valaciclovir, also spelled valacyclovir, is an antiviral drug used in the management of herpes simplex, herpes zoster (shingles), and herpes B. It is a prodrug, which is converted to aciclovir in a persons body. Common adverse drug reactions (≥1% of patients) associated with valaciclovir therapy are the same as for aciclovir, its active metabolite, and include: nausea, vomiting, diarrhea and headache. Infrequent adverse effects (0.1–1% of patients) include: agitation, vertigo, confusion, dizziness, edema, arthralgia, sore throat, constipation, abdominal pain, rash, weakness and/or renal impairment. Rare adverse effects ( Valaciclovir belongs to a family of molecules first described and patented by Paolo Cornaglia Ferraris in 1982 (patents EP0077460 A2, CA1258149A1, DE3273785D1, EP0077460A3, EP0077460B1, US4567182). Valaciclovir is a prodrug, an esterified version of aciclovir that has greater oral bioavailability (about 55%) than aciclovir (10–20%). It is converted by esterases to the active drug aciclovir, as well as the amino acid valine, via hepatic first-pass metabolism. Valacyclovir dose for cold sores Valtrex liver Is metoprolol a diuretic Valacyclovir is the hydrochloride salt of the L-valyl ester of the antiviral drug acyclovir. Orally administered, valacyclovir is rapidly converted to acyclovir which. Each blue, coated, capsule-shaped tablet, debossed with "VC" followed by "500" on one side and nothing on the other side, contains valacyclovir HCl equivalent. Valacyclovir hydrochloride C13H21ClN6O4 CID 135398741 - structure, chemical names, physical and chemical properties, classification, patents, literature. Valacyclovir belongs to the class of medications known as antivirals. It is used to treat a viral infection affecting the skin known as shingles (herpes zoster). It is also used to treat cold sores, and to treat and prevent recurrences of genital herpes. It works by interfering with the way the virus reproduces. Valacyclovir works by stopping the virus from multiplying and spreading to nearby healthy cells. It does not cure shingles, cold sores, or genital herpes, but it does help the sores to heal more quickly, and it relieves pain and discomfort. When used to prevent recurrences of herpes, it also reduces the risk of transmission (spreading) of the infection to others. Presented in part at The American College of Obstetrics and Gynecology 45th Annual Clinical Meeting, Las Vegas, Nevada, 1997, where it received second place prize for papers on current clinical and basic investigation. Objective: To document the frequency of genital herpes recurrences in men and women with histories of recurrent genital herpes during 1 year of continuous, suppressive therapy with valacyclovir hydrochloride (HCl). Methods: In an open-label clinical trial conducted at 11 centers, 127 subjects (46 women and 81 men) with histories of recurrent genital herpes (at least 6 recurrences per year) were treated with valacyclovir HCl (500 mg once daily), and their clinical status was followed up for 1 year. Genital herpes recurrences were documented in diaries, and quarterly clinic visits were made for evaluating lesion recurrences and drug safety. In cases of recurrence, subjects self-treated with valacyclovir HCl 500 mg twice daily for 5 days, then resumed once-daily treatment. Results: After the first 3 months of suppressive therapy, 81% of subjects were free of recurrence. Recurrence-free rates remained undiminished during the second, third, and fourth quarters (84%, 84%, and 91%, respectively) and were similar for men and women.
