Which of the following is known as acetylsalicylic acid and is used as an analgesic?

Aspirin is known as acetylsalicylic acid, a medication that is widely used for its analgesic and anti-inflammatory properties. It works by inhibiting enzymes in the body that contribute to inflammation, pain, and fever, making it effective for alleviating mild to moderate pain. Aspirin also has antipyretic (fever-reducing) and anti-inflammatory effects, which further emphasize its role in pain management.

The name "acetylsalicylic acid" refers to its chemical structure, where an acetyl group is combined with salicylic acid. This combination not only enhances its effectiveness but also reduces gastrointestinal irritation compared to salicylic acid alone. Moreover, aspirin is commonly used in low doses for its antiplatelet properties, helping to reduce the risk of heart attacks and strokes.

Other medications listed, such as ibuprofen, acetaminophen, and naproxen, have different chemical structures and mechanisms of action. For instance, ibuprofen and naproxen are nonsteroidal anti-inflammatory drugs (NSAIDs), while acetaminophen is primarily an analgesic and antipyretic but lacks significant anti-inflammatory properties. Each of these alternatives has its indications and side effects, but only aspirin is specifically known
