Cytochrome P450 (CYP) induction by a new chemical entity results in the increased amount and activity of relevant drug-metabolizing CYPs, which may lead to increase the metabolism of co-medicated drugs, or the metabolism of itself (autoinduction). That will reduce plasma levels, resulting in a decrease in efficacy. siadh scholarly articles
