Which drug class is commonly used to prevent organ transplant rejection?

• A. Immunosuppressant
• B. Lipid-Lowering Agent
• C. Smoking Deterrent
• D. Ophthalmic Anti-Infective

Answer: (A)

Preventing organ transplant rejection relies on dampening the immune system’s response to the new organ. The body tends to see a transplanted organ as foreign, and T cells can attack it. Immunosuppressants slow or block this immune reaction, often using a combination of drugs that target different parts of the immune response. This approach helps the graft survive by reducing acute rejection while allowing some immune activity to protect against infections. Examples include drugs that inhibit T-cell activation, limit lymphocyte proliferation, or modulate immune signaling, often used together for better protection. The other options address different problems: lipid-lowering agents reduce cholesterol, not immune rejection; smoking deterrents help people quit smoking; ophthalmic anti-infectives treat eye infections.
