  • 2.1 Adult Patients With Impaired Renal Function

  • KEPPRA XR dosing must be individualized according to the patient's renal function status. Recommended doses and adjustment for dose for adults are shown in Table 1. To use this dosing table, an estimate of the patient's creatinine clearance (CLcr) in mL/min is needed. CLcr in mL/min may be estimated from serum creatinine (mg/dL) determination using the following formula:

    [140-age (years)] x weight (kg) CLcr = ---------------------------------------------- x 1 0.85 72 x serum creatinine (mg/dL)1. For female patients

    Then CLcr is adjusted for body surface area (BSA) as follows:

    CLcr (mL/min) CLcr (mL/min/1.73m2) = ----------------------------- x 1.73 BSA subject (m2)
