Final answer:
Diclofenac is classified as an NSAID, a type of drug that reduces pain, decreases fever, and lessens inflammation by inhibiting the synthesis of prostaglandins.
Step-by-step explanation:
Diclofenac belongs to the class of drugs known as NSAIDs (Nonsteroidal anti-inflammatory drugs). The term 'nonsteroidal' is used to differentiate these medications from steroids, which also have anti-inflammatory properties but come with a wide array of other effects. NSAIDs, including aspirin, ibuprofen, and naproxen, are commonly used to reduce pain, decrease fever, prevent blood clots, and in higher doses, decrease inflammation. They achieve this by inhibiting the synthesis of prostaglandins, which are compounds that play a key role in causing inflammation and pain in the body. It's important to note that, while effective, NSAIDs can have side effects such as an increased risk of gastrointestinal ulcers and bleeds, heart attack, and kidney disease, especially with long-term use.
