Electric Literature of 125995-03-1, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 125995-03-1, Name is Atorvastatin lactone, molecular formula is C33H33FN2O4. In a Article£¬once mentioned of 125995-03-1
The drug?drug interaction profile of atorvastatin confirms that disposition is determined by cytochrome P450 (CYP) 3A4 and organic anion transporting polypeptides (OATPs). Drugs that affect gastric emptying, including dulaglutide, also affect atorvastatin pharmacokinetics (PK). Atorvastatin is a carboxylic acid that exists in equilibrium with a lactone form in vivo. The purpose of this work was to assess gastric acid?mediated lactone equilibration of atorvastatin and incorporate this into a physiologically-based PK (PBPK) model to describe atorvastatin acid, lactone, and their major metabolites. In vitro acid-to-lactone conversion was assessed in simulated gastric fluid and included in the model. The PBPK model was verified with in vivo data including CYP3A4 and OATP inhibition studies. Altering the gastric acid?lactone equilibrium reproduced the change in atorvastatin PK observed with dulaglutide. The model emphasizes the need to include gastric acid?lactone conversion and all major atorvastatin-related species for the prediction of atorvastatin PK.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 125995-03-1 is helpful to your research., Electric Literature of 125995-03-1
