Suppressing Cyclooxygenase-2 prevents nonalcoholic steatohepatitis and inhibits apoptosis of hepatocytes that are involved in the Akt/p53 signal pathway

0 views | Jan 14 2017

Wu J, et al.'s findings suggested that suppressing COX-2 can improve steatohepatitis by inhibiting hepatocyte apoptosis in mice via regulating the Akt/p53 pathway. Celecoxib treatment may be a favorable treatment option for NASH. [Read the Full Post]

Solitary Inhibition of the Breast Cancer Resistance Protein Efflux Transporter Results in a Clinically Significant Drug-Drug Interaction with Rosuvastatin by Causing up to a 2-Fold Increase in Statin Exposure

1030 views | Jan 13 2017

Elsby R et al. found that solitary inhibition of the intestinal BCRP transporter can result in clinically significant DDIs with rosuvastatin, causing up to a maximum 2-fold increase in exposure, which may warrant statin dose adjustment in clinical practice. [Read the Full Post]
