UDP-Glucuronosyltransferase (UGT) Polymorphisms Affect Atorvastatin Lactonization In Vitro and In Vivo
30 Sept 2009
Abstract excerpt
The response to statins shows large interpatient variability. Atorvastatin delta-lactone is pharmacologically inactive but has been associated with toxicity. We investigated the role of UDP-glucuronosyltransferases (UGTs) in atorvastatin lactonization. In human liver microsomes, lactonization was correlated with UGT1A3 (r(s) = 0.61, P < 0.0001) but not with UGT1A1. Surprisingly, lactone formation was...
