Which drug class is primarily used to relieve pain?

The primary drug class used to relieve pain is analgesics. Analgesics are specifically designed to alleviate discomfort and pain through various mechanisms in the body. They can range from over-the-counter medications, such as acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs), to stronger prescription options like opioids. Because their main function is to address pain, they are essential in both acute and chronic pain management.

In contrast, the other drug classes have different primary purposes. Antacids are used to neutralize stomach acid and relieve symptoms of indigestion or heartburn. Antidepressants are primarily prescribed to treat mood disorders, such as depression and anxiety, with effects that might indirectly improve quality of life but are not focused on pain relief. Antihistamines are mainly used to treat allergic reactions by blocking histamine receptors, thus helping to alleviate symptoms like runny nose or hives. Each of these classes serves distinct therapeutic purposes, while analgesicsare directly aimed at managing pain.
