Extended-release Microsphere Capsule-based Oxycodone

**Semantic type:** Organic Chemical|Pharmacologic Substance

**Definition:** A wax microsphere capsule formulation of oxycodone, a semi-synthetic, morphine-like opioid alkaloid, with analgesic activity. Upon administration, oxycodone exerts its analgesic activity by binding to the mu-receptors in the central nervous system (CNS), thereby mimicking the effects of endogenous opioids. Due to the unique formulation, extended-release microsphere capsule-based oxycodone may provide an identical pharmacokinetic profile regardless of whether the capsule is intact when ingested or if ingested via enteral feeding tube, leading to a predictable level of analgesia in patients that must be transitioned from oral to enteral administration.

**Synonyms:** - Oxycodone ER Microsphere Capsule - Xtampza ER
