In our inaugural episode of Eight Drugs a Week we are very lucky to be joined by two former IATDMCT Presidents, Loralie Langman and Pierre Marquet. Both are very well known for their work with immunosuppressant drugs, particularly in the context of transplantation.   In this episode we talk about: Planning the ideal immunosuppressant monitoring program in solid organ transplant recipients Why France is ahead of the curve in immunosuppressant TDM Why a particular mycophenolate TDM RCT is the ‘poster study’ for TCI in the TCI vs TDM debate Lessons learned in microsampling using DBS and VAMs for immunosuppressant monitoring   Eight Drugs a Week is supported by the International Association of Therapeutic Drug Monitoring and Clinical Toxicology (IATDMCT).
