This study evaluates the carvedilol-lercanidipine drug interaction, and the influence of chronic kidney disease (CKD) on both drugs. Patients with high blood pressure (8 with normal renal function {[}control] and 8 with CKD with estimated glomerular filtration rate categories of G3b to G5 {[}12-38 mL/min/1.73 m(2)]) were included and prescribed 3 different treatment regimens, a single oral dose of racemic carvedilol 25 mg (CAR), a single oral dose of racemic lercanidipine 20 mg (LER), and single oral doses of CAR plus LER. Blood samples were collected and variations in heart rate were assessed (using isometric exercise with handgrip) for up to 32 hours. Lercanidipine pharmacokinetics were not enantioselective, and were not affected by carvedilol and CKD. Carvedilol pharmacokinetics (data presented as median) were enantioselective with higher plasma exposure of (R)-(+)-carvedilol in both control (103.5 vs 46.0 ng center dot h/mL) and CKD (190.6 vs 98.9 ng center dot h/mL) groups. Lercanidipine increased the area under the plasma concentration-time curve of only (R)-(+)-carvedilol in the CKD group (190.6 vs 242.2 ng center dot h/mL) but not in the control group (103.5 vs 98.7 ng center dot h/mL). CKD increased plasma exposure (46.0 vs 98.9 ng center dot h/mL) and effect-compartment exposure (5.5 vs 20.9 ng center dot h/mL) to (S)-(-)-carvedilol, resulting in higher beta-adrenergic inhibition (10.0 vs 6.1 bpm). Therefore, carvedilol dose titration in CKD patients with estimated glomerular filtration rate categories of G3b to G5 should be initiated, with no more than half the dose used for patients with normal renal function.
