Study summary

Limited data are available on valaciclovir use in children and valaciclovir is not currently approved for use in pediatrics. The marketed formulation of valaciclovir is not ideal for use in pre-adolescent patients who may have trouble swallowing solid oral dosage forms. An extemporaneous suspension formulation of valaciclovir has been developed to expedite the provision of benefits to children similar to those from administration of valaciclovir solid formulations in adults.

Interventions

  • DrugValaciclovir

    Valaciclovir will be administered as an extemporaneously prepared suspension formulation. Valaciclovir oral suspension will be prepared by crushing marketed Valtrex Caplets 500 milligram (mg) and suspending the resultant powder in Suspension Structured Vehicle USNF with dose strength of 25 milligram per milliliter (mg/mL) or 50 mg/mL.

What researchers measure

Primary outcomes

  1. Plasma acyclovir and valaciclovir concentrations pre-dose (within 15 minutes of dose administration) and at 0.5, 1, 2, 4 and 6 hours following administration of the valaciclovir oral suspension dose.

    Time frame: 0.5, 1, 2, 4 and 6 hours
