Immunosuppressants such as………….., prevent transplanted organs from being rejected in recipients.

Correct option is A

The correct answer is (a) Cyclosporine. Cyclosporine is an immunosuppressant drug that is used to prevent organ rejection in transplant patients. It works by inhibiting the activity of the immune system, which might otherwise recognize the transplanted organ as foreign and attack it.
Important Key Points:
· Cyclosporine is crucial in transplant medicine for preventing organ rejection.
· It inhibits T-lymphocytes, reducing the immune response against the transplanted organ.
· The drug is used for kidney, liver, heart, and other organ transplants.
· Cyclosporine must be taken for the lifetime of the transplanted organ to prevent rejection.
· Regular monitoring of drug levels is necessary to avoid side effects.
· Cyclosporine has revolutionized transplant success rates and patient outcomes.
Knowledge Booster:
· Calcitonin: A hormone involved in calcium regulation, not related to organ transplants.
· Thrombin: A protein involved in blood clotting, not used for immunosuppression.
· Aspirin: A common pain reliever and anti-inflammatory, not an immunosuppressant.
