What Is Oxycodone?

Oxycodone is a semi-synthetic opioid analgesic derived from thebaine. It binds to mu, kappa and delta opioid receptors in the brain and spinal cord, reducing the perception of pain and producing a sense of wellbeing.

What Is OxyContin?

OxyContin is the extended-release (ER) formulation of oxycodone. Its patented matrix delivers oxycodone over a 12-hour period, making it suitable for around-the-clock management of moderate to severe chronic pain in opioid-tolerant patients.
