Final answer:
Acetaminophen and ibuprofen are used under the Analgesia Medical Directive for pain and fever management. NSAIDs like ibuprofen reduce prostaglandin production, which leads to less inflammation and pain, while acetaminophen is preferred for patients unable to tolerate NSAIDs. Both have different mechanisms and safety profiles but are prevalent non-prescription pain medications.
Step-by-step explanation:
Under the Analgesia Medical Directive, both acetaminophen (known as paracetamol outside of the US) and nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen are common medications used to manage pain and reduce fever. NSAIDs like ibuprofen, aspirin, and naproxen act by inhibiting the production of prostaglandins through blocking the cyclooxygenase (COX) enzyme, thus reducing inflammation and pain. However, they are associated with potential side effects, including gastrointestinal, liver, or kidney damage with long-term use. Acetaminophen is an alternative to NSAIDs, particularly for those who cannot tolerate them, such as patients with peptic ulcer disease or those for whom the blood-thinning effects of aspirin are contraindicated. Acetaminophen primarily functions as an analgesic and antipyretic with a more favorable safety profile concerning gastric issues.
Over-the-counter (OTC) ibuprofen and naproxen are available in doses that are approximately half of the prescription versions, with ibuprofen being commonly sold in 200 mg tablets. While NSAIDs and acetaminophen have different mechanisms of action and safety profiles, they are both used as pain relievers and are critical components in managing pain without resorting to prescription opioids, which carry serious risks of addiction, abuse, and overdose.
