Mycophenolic Acid

Mycophenolic Acid Glucuronide

Clinical relevance

Mycophenolic acid (MPA) is used as an immunosuppressant agent to prevent organ transplant rejection. MPA selectively inhibits the synthesis of purines and specifically reduces the growth of B- and T-lymphocytes. Furthermore, MPA is also used to treat autoimmune diseases such as psoriasis, systemic lupus erythematosus or scleroderma.

Therapeutic monitoring of MPA in the blood is required to adjust individual concentrations within the therapeutic window and to attain a favourable ratio between therapeutic effects and side effects. Currently available drugs contain mycophenolate mofetil or mycophenolate sodium, which are both completely metabolised into the active metabolite MPA. For excretion, MPA is bound to glucuronic acid.

This parameter set allows the quantitative determination of mycophenolic acid and its metabolite mycophenolic acid glucuronide in human serum or plasma samples by LC-MS/MS (liquid chromatography mass spectrometry).
It is intended as a monitoring test for patients treated with mycophenolate mofetil or mycophenolate sodium as an aid to ensure drug levels are maintained within the therapeutic range.

 

MassTox® TDM Serie A

The Parameter Set is a part of the Series A modular system, which enables the analysis of all parameters without switching column or changing the mobile phases, thereby minimising required workload in the laboratory.
It consists of:
• MassTox® TDM Basic Kit A
• Specific MassTox® TDM Parameter Set (13 different parameter sets available)
• Analytical column MassTox® TDM MasterColumn® A
