Which statement best differentiates Aspirin from other anti-inflammatory drugs?

• A. They are nonsteroidal anti-inflammatories that inhibit prostaglandin synthesis.
• B. They are antibiotics with no anti-inflammatory effect.
• C. They are steroids ending in -one and will NOT inhibit Prostaglandin Synthesis.
• D. They all increase prostaglandin synthesis.

Answer: (C)

Aspirin’s distinguishing feature is that it belongs to the nonsteroidal anti-inflammatory drug (NSAID) class and, unlike many other drugs in this group, it irreversibly acetylates the COX enzymes in platelets. This means it permanently disables platelet COX-1, leading to a lasting reduction in thromboxane A2 and a persistent antiplatelet effect that lasts for the life of the platelet (about a week). Other NSAIDs also inhibit cyclooxygenase to reduce prostaglandin synthesis, but they do so reversibly and their effects wane as the drug is cleared. Steroids (corticosteroids) are a different drug class with a distinct mechanism: they work by blocking phospholipase A2 and altering gene expression, not by irreversible COX inhibition. So the key idea is that aspirin is an NSAID with an irreversible COX inhibition effect on platelets, setting it apart from steroids and from reversible NSAID effects.
