Description

Tramadol – Centrally Acting Opioid Analgesic (Rx, Controlled in Many Regions)

Tramadol is a centrally acting analgesic used to treat moderate to moderately severe pain. It has a dual mechanism of action:

• Weak μ-opioid receptor agonist
• Inhibits reuptake of serotonin and norepinephrine, enhancing pain control pathways

This combination provides effective pain relief with less potency than strong opioids, but it still carries risks such as dependence and side effects.
