Bnon-narcotic analgesic and antipyretic acting as an enzyme inhibitor
Cantibiotic acting as an enzyme activator
Dantacid acting as a receptor antagonist

The acetyl derivative of salicylic acid is aspirin, a non-narcotic analgesic and antipyretic. It blocks the enzyme that makes prostaglandins, so it is an enzyme inhibitor. It is not narcotic, not an antibiotic and not an antacid.
