What is Xtampza ER?

Xtampza ER is A strong prescription pain medicine that contains an opioid (narcotic) that is used to manage pain severe enough to require daily, around-the-clock, long-term treatment with an opioid, when other pain treatments such as non-opioid pain medicines or immediate-release opioid medicines do not treat your pain well enough or you cannot tolerate them.

It is a long-acting (extended-release) opioid pain medicine that can put you at risk for overdose and death. Even if you take your dose correctly as prescribed by your healthcare provider, you are at risk for opioid addiction, abuse, and misuse that can lead to death.

It is not for use to treat pain that is not around-the-clock.


XTAMPZA ER (oxycodone) extended-release capsules are an opioid agonist for oral use. The capsules contain microspheres formulated with oxycodone base and are supplied in strengths of 9 mg (equivalent to 10 mg oxycodone HCl), 13.5 mg (equivalent to 15 mg oxycodone HCl), 18 mg (equivalent to 20 mg oxycodone HCl), 27 mg (equivalent to 30 mg oxycodone HCl), and 36 mg (equivalent to 40 mg oxycodone HCl) capsules. The capsule strengths describe the amount of oxycodone base per capsule. The structural formula for oxycodone is as follows:

Chemical Structure

  • C18H21NO4              
  •  MW 315.37 g/mol


The chemical name is 4,5 α-Epoxy-14-hydroxy-3-methoxy-17-methylmorphinan-6-one.

Oxycodone base is a white, odorless crystalline powder derived from the opium alkaloid, thebaine. Oxycodone is present as myristate salt in the XTAMPZA ER formulation.

Each XTAMPZA ER capsule contains either 9, 13.5, 18, 27, or 36 mg of oxycodone (equivalent to 10, 15, 20, 30, or 40 mg of oxycodone HCl, respectively) and the following inactive ingredients: myristic acid, yellow beeswax, carnauba wax, stearoyl polyoxyl-32 glycerides, magnesium stearate, and colloidal silicon dioxide. The capsule shells collectively contain titanium dioxide, hypromellose, and water. Additionally, the 9 mg and 18 mg strength capsule shells contain yellow iron oxide, the 13.5 and 36 mg strength capsule shells contain red iron oxide, and the 27 mg strength capsule shells contain black iron oxide.

Mechanism of Action

Oxycodone is a full opioid agonist and is relatively selective for the mu receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of oxycodone is analgesia. Like all full opioid agonists, there is no ceiling effect to analgesia for oxycodone. Clinically, dosage is titrated to provide adequate analgesia and may be limited by adverse reactions, including respiratory and CNS depression.

The precise mechanism of the analgesic action is unknown. However, specific CNS opioid receptors for endogenous compounds with opioid-like activity have been identified throughout the brain and spinal cord and are thought to play a role in the analgesic effects of this drug. In addition, when oxycodone binds to mu-opioid receptors, it results in positive subjective effects, such as drug liking, euphoria, and high.

What is the most important information I should know about Xtampza ER?

  • Get emergency help right away if you take too much Xtampza ER (overdose). When you first start taking Xtampza ER, when your dose is changed, or if you take too much (overdose), serious life-threatening breathing problems that can lead to death may occur.
  • Taking Xtampza ER with other opioid medicines, benzodiazepines, alcohol, or other central nervous system depressants (including street drugs) can cause severe drowsiness, decreased awareness, breathing problems, coma, and death.
  • Never give anyone else your Xtampza ER. They could die from taking it. Selling or giving away Xtampza ER is against the law.
  • Store Xtampza ER securely, out of sight and reach of children, and in a location not accessible by others, including visitors to the home.
