U.S., Sept. 10 -- ClinicalTrials.gov registry received information related to the study (NCT07810816) titled 'Prospective Pharmacogenetic Cohort Study of CYP2D6 Metabolizer Phenotype, Analgesic Failure, and Adverse Effects in Postoperative Patients Receiving Tramadol by Elastomeric Infusion Pump' on Sept. 03.

Brief Summary: This prospective pharmacogenetic cohort will enroll postoperative patients receiving a standardized tramadol-containing elastomeric analgesia pump. CYP2D6 genotype will be measured but will not determine treatment during the 72-hour study window. Participants with non-normal metabolizer phenotypes will be compared with normal metabolizers for analgesic treatment failure and adverse effects. Pain, rescue medication, pump...
