Where is oxycodone broken down?
Oxycodone is extensively metabolized in the liver and only ca. 10% of the dose is excreted unchanged in urine in adults (Pöyhiä et al., 1992; Kirvelä et al., 1996; Lalovic et al., 2006), but the majority of the metabolites are excreted in urine (Lalovic et al., 2006).
Where does oxycodone bind to?
Oxycodone binds to the μ-opioid receptor and activates the μ-opioid receptor, whereas it does not bind to the κ-opioid receptor and does not activate the κ-opioid receptor.

While the half-life of oxycodone is approximately 3–4 hours, the metabolic process will last longer. A range of drug screenings may detect oxycodone.
How is oxycodone best absorbed?
Oxycodone is well absorbed from OxyContin Tablets with an oral bioavailability of 60% to 87%.
Is oxycodone a full opiate?
