Which drug class is used to prevent immune reactions after organ transplantation?

• A. Immunosuppressant
• B. Lipid-Lowering Agent
• C. Platelet Inhibitor
• D. Thyroid Hormone

Answer: (A)

Preventing immune reactions against a transplanted organ requires dampening the body's immune response. The drug class that does this is immunosuppressants, which suppress or modulate T-cell activation and proliferation and often reduce inflammatory signaling. By lowering the immune system’s attack on the graft, these drugs help the transplanted organ survive longer. The other options don't fit this purpose: lipid-lowering agents target cholesterol, platelet inhibitors reduce clotting, and thyroid hormone replaces missing thyroid hormone. So immunosuppressants are the appropriate choice to prevent immune reactions after transplantation.
