Final answer:
Cyclosporine is an immunosuppressant drug used for renal transplant and has possible side effects such as increased risk of infections, high blood pressure, kidney damage, and increased susceptibility to cancer.
Step-by-step explanation:
An immunosuppressant drug commonly used for renal transplant is cyclosporine. It works by inhibiting the production of interleukin, which is a cytokine messenger that increases expression in T cells. This suppression of the immune system helps prevent rejection of the transplanted kidney.
Some possible side effects of immunosuppressants like cyclosporine include increased risk of infections, high blood pressure, kidney damage, and an increased susceptibility to certain types of cancer.
