Amitriptyline

Therapeutic drug monitoring of amitriptyline, a tricyclic antidepressant (TCA) commonly prescribed for depression, anxiety disorders, and neuropathic pain management, is essential due to its narrow therapeutic window, significant inter-patient pharmacokinetic variability, and potential for cardiac toxicity at elevated concentrations. UTAK quality control materials containing amitriptyline and its active metabolite nortriptyline are available in both serum and urine matrices, supporting immunoassay screening, HPLC, and LC-MS/MS confirmatory methods used in TDM and pain management laboratory testing workflows. Stock TCA panels and custom therapeutic drug monitoring solutions can incorporate additional tricyclic compounds such as desipramine, doxepin, imipramine, and clomipramine to meet your laboratory’s specific antidepressant testing requirements.
