Tapentadol is a prescription pain medication used to treat moderate to severe acute pain. It works by affecting how the brain perceives pain, combining opioid receptor activity with inhibition of norepinephrine reuptake. Tapentadol provides effective pain relief with a lower risk of gastrointestinal side effects compared to traditional opioids. It is often prescribed for conditions like post-surgical pain or chronic pain that requires strong treatment. Like other opioids, it should be used under medical supervision to avoid potential misuse or dependence.
