Over 80% of kidney transplantations utilize antibody induction therapy to prevent early rejection. Patients seeking information on **what drug is used to prevent transplant rejection** can benefit from understanding the range of immunosuppressive medications available. These life-saving therapies are essential for the long-term success of organ transplantation.

With over 42,000 organ transplants in the U.S. in 2022, preventing rejection is critical [1.7.1]. So, **which hormone prevents graft rejection?** The primary answer lies in a class of potent, immune-suppressing hormones known as **glucocorticoids**, and their synthetic versions, corticosteroids [1.2.1, 1.2.2].

Approximately 10-20% of kidney transplant recipients experience acute rejection in the first year. Knowing which of the following is used as first line treatment for a severe cellular rejection episode is critical for managing this immune response and protecting the transplanted organ.

According to the American Kidney Fund, most organ transplant recipients must take anti-rejection drugs for the rest of their lives. These life-saving medications prevent the body's immune system from attacking and destroying the new organ, a process known as rejection. This lifelong commitment, however, involves managing complex medication regimens and balancing the benefits of a new organ against the long-term side effects of chronic immunosuppression.

Macrolide immunosuppressants are a class of compounds first developed from soil fungi that possess potent immunosuppressive properties. Understanding what is a macrolide immunosuppressant is crucial for grasping their role in modern medicine, particularly in preventing organ rejection and treating autoimmune diseases like atopic dermatitis.

Initially discovered from a soil fungus (*Streptomyces tsukubaensis*) in Japan, tacrolimus is a powerful immunosuppressive agent. When asking, 'What class of drug is tacrolimus?', the primary answer is a calcineurin inhibitor, a class of medications that significantly reduces the immune system's activity.

The success of modern organ transplantation relies heavily on immunosuppressive medications, with current one-year graft survival rates often exceeding 90% in many centers. To ensure a transplanted organ is not rejected, it is crucial to understand what drugs are used for transplant rejection and how these complex medication protocols manage the body's immune system.

Over 80% of kidney transplant recipients are prescribed tacrolimus upon discharge. Yet, the question remains: why is tacrolimus bad? While it is an essential and powerful immunosuppressant, the drug has a narrow therapeutic index and is associated with significant potential toxicities.
