Pharmacokinetics of pregabalin in subjects with various degrees of renal function.

The objectives of this study were to determine the single-dose pharmacokinetics of pregabalin in subjects with various degrees of renal function, determine the relationship between pregabalin clearance and estimated creatinine clearance (CLcr), and measure the effect of hemodialysis on plasma levels of pregabalin. Results form the basis of recommended pregabalin dosing regimens in patients with decreased renal function. Thirty-eight subjects were enrolled to ensure a wide range of renal function (CLcr < 30 mL/min, n = 8; 30-50, n = 5; 50-80, n = 7; and > 80, n = 6).
