Correction to “Complete Substrate Inhibition of Cytochrome P450 2C8 by AZD9496, an Oral Selective Estrogen Receptor Degrader” ================================================================================================================================= In the above article [Bapiro TE, Sykes A, Martin S, Davies M, Yates JWT, Hoch M, Rollison HE, and Jones B (2018) *Drug Metab and Dispos* **46** (9):[1268-1276](http://dmd.aspetjournals.org/lookup/volpage/46/1268); DOI: [https://doi.org/10.1124/dmd.118.081539](https://doi.org/10.1124/dmd.118.081539)], there is an error in equation 1 and 3 where [S]in the numerator from both equations was erroneously left out and not caught during the proofing process. The correct forms in GraphPad Prism have been used to fit the data and the mistake is only in the transcribing in the paper. The corrected equations 1 and 3 are provided below. The authors regret this error and apologize for any inconvenience this may have caused. Equation 1![Formula][1] Equation 3![Formula][2] * Copyright © 2019 by The American Society for Pharmacology and Experimental Therapeutics [1]: /embed/graphic-1.gif [2]: /embed/graphic-2.gif
