Alpha-adrenoceptors and angiotensinogen gene expression in opossum kidney cells.

abstract：:The selective vasopressin V2-receptor antagonist tolvaptan is eliminated almost exclusively by non-renal mechanisms. As renal impairment can influence the pharmacokinetics of drugs even when eliminated by non-renal mechanisms, we evaluated the effect of renal insufficiency on the pharmacokinetics/pharmacodynamics of t...
