Which of the following medications helps relieve headaches and other minor aches?

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that is commonly used to relieve headaches, as well as other minor aches and pains. It works by inhibiting the production of certain chemicals in the body that contribute to inflammation and pain. This makes ibuprofen effective not only for headaches but also for muscle aches, toothaches, menstrual cramps, and other discomforts.

It is distinct from the other options, which have different purposes. Hydromorphone and meperidine are opioids, primarily used for managing moderate to severe pain, and are not typically indicated for minor aches due to their stronger effects and risk of dependency. Calcium channel blockers are primarily used to treat high blood pressure and certain heart conditions, and they do not serve the purpose of pain relief for headaches or minor aches. Thus, ibuprofen stands out as the appropriate choice for headache relief among the provided options.
