Aspadol 100mg is an opioid analgesic containing tapentadol, used to treat moderate to severe pain. It works through a dual mechanism, acting as both an opioid receptor agonist and a norepinephrine reuptake inhibitor, providing effective pain relief. It is commonly prescribed for conditions such as postoperative pain, acute injuries, and chronic pain like osteoarthritis. While effective, Aspadol 100mg should be used with caution due to potential side effects such as drowsiness, nausea, and the risk of dependency. Always follow the prescribed dosage and consult a healthcare provider for guidance.
