Pharmacology Made Easy: The Immune System Questions and Answers | Latest Version | 2025/2026 | Correct & Verified What is the primary action of corticosteroids in managing immune system disorders? They suppress inflammation and modulate the immune response. How do antihistamines help in allergic reactions? They block histamine receptors to reduce symptoms such as itching, swelling, and sneezing. What should be monitored in a patient receiving long-term corticosteroid therapy? Blood sugar levels, as corticosteroids can increase blood glucose. Why are vaccines important in the prevention of infectious diseases? They stimulate the immune system to produce antibodies without causing the disease. What is the role of immunosuppressive drugs in organ transplantation? To prevent the immune system from rejecting the transplanted organ by suppressing immune activity. 2 What is the primary side effect of methotrexate when used as an immunosuppressant? Bone marrow suppression, which can lead to anemia, leukopenia, and thrombocytopenia. Why is it important for patients on immunosuppressants to avoid infection? Because immunosuppressants lower the body’s ability to fight infections, making patients more susceptible to illnesses. What is the action of monoclonal antibodies in treating autoimmune diseases? They target specific molecules involved in the immune response, helping to reduce inflammation and tissue damage. What is the primary function of the immune system? To protect the body from harmful pathogens, such as bacteria, viruses, and fungi. What is the mechanism of action of antiretroviral drugs in the treatment of HIV? They inhibit the replication of the HIV virus by targeting different stages of the virus’s life cycle. 3 Why are live vaccines not recommended for immunocompromised individuals?

Rash, itching, swelling, and difficulty breathing are common symptoms of an allergic reaction. Why should a patient on corticosteroids avoid sudden discontinuation of the drug? Sudden discontinuation can lead to adrenal insufficiency, as the body’s own production of corticosteroids may be suppressed. What is the role of interferons in the treatment of viral infections? They boost the immune response by enhancing the ability of immune cells to fight off viral infections. 4 How does the use of nonsteroidal anti-inflammatory drugs (NSAIDs) affect the immune system? NSAIDs inhibit the production of prostaglandins, which reduces inflammation and pain but may also impair immune function. What is a possible side effect of long-term use of immunosuppressants? Increased risk of infections and certain cancers due to reduced immune surveillance. What is the mechanism of action of biologic drugs in autoimmune conditions? Biologic drugs target specific components of the immune system to reduce inflammation and prevent tissue damage. Why are people with autoimmune diseases
