Oxycodone 40mg

Oxycodone 40mg – IR & ER Formulas for Moderate to Severe Pain Relief

Oxycodone 40mg is a prescription-strength opioid analgesic used to manage moderate to severe chronic pain in patients who require continuous, long-term opioid therapy. It is available in both Immediate-Release (IR) and Extended-Release (ER) versions, offering versatile pain management tailored to individual medical needs.

Oxycodone works by binding to mu-opioid receptors in the central nervous system, modifying the brain’s perception and emotional response to pain. The 40mg dose is typically reserved for opioid-tolerant patients and should be used under professional supervision due to the high risk of dependence and overdose.

It is marketed under trusted brand names including OxyContin®, Oxynorm®, Longtec®, Xtampza ER®, and others — including formulations by Mundipharma in the UK.
