Assay Method for the Analgesic Nucynta

Tapentadol can be a problematic compound for HPLC analysis due to the Amine functional group. Tertiary amines are often particularly difficult to obtain a good peak shape using Reversed Phase methods. Peak tailing has been reported in several published papers in the literature.

With this Method, a sharp Peak is obtained due to the unique retention mode.

Sample Preparation: 75mg strength Nucynta® tablet was ground and weighed in a 25mL volumetric flask. A portion of 50:50 Solvent A / Solvent B diluent was added and the flask was sonicated 10 minutes. It was then diluted to mark and filtered with a 0.45µm Nylon Syringe Filter (MicroSolv Tech Corp.). The filtrate was diluted 1:5 for HPLC injections.
t0: 0.9 minutes

Note: Tapentadol is an analgesic compound used to treat moderate to severe pain. Its efficacy is due to two modes of action: one is an agonist of the µ-opioid receptor and another as a norepinephrine reuptake inhibitor.
