Published in August 2007. At the other extreme, ultrarapid metabolisers metabolise the drug rapidly, resulting in a lack of therapeutic response in these individuals. As a result, the higher plasma concentration of nortriptyline in intermediate metabolisersincreases the risk of potential side effects. Therefore, potential changes in drug concentration may cause treatment failure. The human body contains P450 enzymes to process medications. Note: The IC50 values of several OCT2 inhibitors measured using 1-methyl-4-phenylpyridinium (MPP+) as a substrate were larger than those measured using metformin or creatinine as substrate.
