Individuals with low expression of CYP2D6 are designated as poor metabolizers while individuals with high expression of CYP2D6 are designated as fast metabolizers. This information is important for healthcare professionals to know as it determines the dose of opioids a patient will need in order to achieve the desired analgesic effect.
People who have less CYP2D6 expression are identified as slow metabolizers, while those with more expression are labeled as rapid metabolizers. Understanding these distinctions helps healthcare professionals determine the appropriate opioid dose to achieve pain relief effectively.
