HPLC Method for Analysis of Acetaminophen and Oxycodone

11 Acetaminophen is a p-aminophenol derivative with analgesic and antipyretic activities. It has weak anti-inflammatory properties, may cause liver, blood cell, and kidney damage. It is a nonprescription medication for mild-to-moderate pain and fever. Oxycodone is semi-synthetic opioid type drug that is used to help relieve moderate to severe pain. Primesep 200, a reverse phase column, contains embedded acidic ionizable groups and can retain Acetaminophen and Oxycodone. The method is UV compatible and can be used as a general approach for analyzing similar compounds.
