Opioid Agonists

Opioid agonists are medications that activate certain receptors in the brain called opioid receptors, which naturally respond to pain and feelings of pleasure. These drugs are used to relieve severe pain, such as after surgery or in cancer care. They work by blocking pain signals, providing relief, and often producing feelings of euphoria. While effective for pain management, they can also cause side effects like drowsiness, dependence, and addiction if not carefully controlled. Examples include medications like morphine, oxycodone, and fentanyl, used under medical supervision to ensure safe and effective treatment.
