Definition
Rofecoxib is a nonsteroidal anti-inflammatory drug (NSAID) that was used to treat arthritis, acute pain, and menstrual symptoms. It worked by blocking an enzyme called COX-2, which is involved in inflammation and pain. Think of it as a targeted pain reliever focusing specifically on the source of the inflammation. However, rofecoxib was withdrawn from the market due to concerns about increased risk of heart attacks and strokes. It's a classic example of how even helpful drugs can have serious side effects.
