Immunosuppressant Medications Overview for PTCB Exam Prep
Master immunosuppressant drug classes, key brand/generic names, and safety considerations tested on the PTCB certification exam.
Understanding Immunosuppressants for the PTCB Exam
Immunosuppressant medications are critical in transplant medicine, autoimmune disease management, and oncology. Pharmacy technicians must recognize these drugs, their brand names, and key handling requirements. Review this topic and more in our PTCB exam prep resources.
Major Immunosuppressant Classes
Calcineurin Inhibitors
Cyclosporine (Sandimmune, Neoral) and tacrolimus (Prograf) prevent T-cell activation. Both require therapeutic drug monitoring due to narrow therapeutic indices. Tacrolimus is the most widely used agent in solid organ transplantation.
Antimetabolites
Mycophenolate mofetil (CellCept) and azathioprine (Imuran) inhibit lymphocyte proliferation. Mycophenolate is a hazardous drug requiring safe handling precautions during dispensing.
mTOR Inhibitors
Sirolimus (Rapamune) and everolimus (Zortress) block the mTOR pathway. These are sometimes used as alternatives to calcineurin inhibitors to reduce nephrotoxicity.
Key Safety Considerations
- Many immunosuppressants are hazardous drugs requiring gloves during handling
- Grapefruit juice interacts with cyclosporine and tacrolimus by inhibiting CYP3A4
- Patients on immunosuppressants should avoid live vaccines
- Trough levels must be drawn at consistent times before the next dose
Storage and Dispensing
Cyclosporine oral solution should not be stored in the refrigerator after opening. Tacrolimus capsules should be dispensed in the original packaging to protect from moisture.
