Adverse effects of substances can be classified into the following groups: We list the most important adverse effects. Many drug interactions are a result of inhibition or induction of cytochrome P450 enzymes (CYP450). This video demonstrates how to use the SOCRATES acronym when taking a history of pain or other symptoms. What induces CYP450? 65 CYP1A is induced by polycyclic hydrocarbons and other compounds such as benzo ( a )pyrene, -naphthoflavone and 2,3,7,8-tetrachlorodibenzo- p -dioxin (TCDD).
