Dosage Adjustments in Adult Patients with Renal Impairment

KEPPRA XR dosing must be individualized according to the patient's renal function status. Recommended dosage adjustments for adults are shown in Table 1. In order to calculate the dose recommended for patients with renal impairment, creatinine clearance adjusted for body surface area must be calculated. To do this, an estimate of the patient's creatinine clearance (CLcr) in mL/min must first be calculated using the following formula:

CLcr=	[140-age (years)] × weight (kg) --------------------------------------	(× 0.85 for female patients)
	72 × serum creatinine (mg/dL)

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

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

Table 1: Dosage Adjustment Regimen for Adult Patients with Renal Impairment
Group	Creatinine Clearance (mL/min/1.73m2)	Dosage (mg)	Frequency
Normal	> 80	1000 to 3000	Every 24 hours
Mild	50 – 80	1000 to 2000	Every 24 hours
Moderate	30 – 50	500 to 1500	Every 24 hours
Severe	< 30	500 to 1000	Every 24 hours
