Description

Curator's Comment: description was created based on several sources, including http://reference.medscape.com/drug/oxycontin-xtampza-er-oxycodone-343321 | https://www.ncbi.nlm.nih.gov/pubmed/23880538 | https://www.drugs.com/oxycodone.html

Oxycodone is a semisynthetic opioid used for the management of acute and chronic pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. Oxycodone is a highly selective full agonist of the μ-opioid receptor (MOR), with low affinity for the δ-opioid receptor (DOR) and κ-opioid receptor (KOR). After oxycodone binds to the MOR, a G protein-complex is released, which inhibits the release of neurotransmitters by the cell by reducing the amount of cAMP produced, closing calcium channels, and opening potassium channels. After a dose of conventional (instant-release) oral oxycodone, the onset of action is 10–30 minutes, and peak plasma levels of the drug are attained within roughly 30–60 minutes in contrast, after a dose of OxyContin (an oral controlled-release formulation), peak plasma levels of oxycodone occur in about three hours. The duration of instant-release oxycodone is 3 to 6 hours, although this can be variable depending on the individual. Oxycodone in the blood is distributed to skeletal muscle, liver, intestinal tract, lungs, spleen, and brain. Serious side effects of oxycodone include reduced sensitivity to pain (beyond the pain the drug is taken to reduce), euphoria, anxiolysis, feelings of relaxation, and respiratory depression. Common side effects of oxycodone include constipation (23%), nausea (23%), vomiting (12%), somnolence (23%), dizziness (13%), itching (13%), dry mouth (6%), and sweating (5%).

OxyContin is NOT intended for use as a prn analgesic. Physicians should individualize treatment in every case, initiating therapy at the appropriate point along a progression from non-opioid analgesics, such as non-steroidal anti-inflammatory drugs and acetaminophen to opioids in a plan of pain management such as outlined by the World Health Organization, the Agency for Healthcare Research and Quality (formerly known as the Agency for HealthCare Policy and Research), the Federation of State Medical Boards Model Guidelines, or the American Pain Society. OxyContin is not indicated for pain in the immediate postoperative period (the first 12-24 hours following surgery), or if the pain is mild, or not expected to persist for an extended period of time. OxyContin is only indicated for postoperative use if the patient is already receiving the drug prior to surgery or if the postoperative pain is expected to be moderate to severe and persist for an extended period of time. Physicians should individualize treatment, moving from parenteral to oral analgesics as appropriate. (See American Pain Society guidelines.) Launch Date 1950

Sample Use Guides

In Vivo Use Guide

For opioid naïve patients, initiate treatment with 5 mg to 15 mg every 4 to 6 hours as needed for pain.

Route of Administration: Oral

In Vitro Use Guide

Human embryonic kidney (HEK)-293 were used for activity evaluation. Receptor G protein-mediated responses were determined by measuring changes in cAMP using the cAMP–homogenous timeresolved fluorescence kit (Cisbio, Codolet, France). MOR, KOR, DOR all couple to Gai so G protein coupling was measured as inhibition of forskolin-stimulated cAMP accumulation in the presence of 1.5 mkM NKH-477 (water-soluble forskolin, Tocris catalog #1603) and 500 mkM 3-isobutyl-1-methylxanthine (IBMX). cAMP accumulation assays were run in parallel with b-arrestin-2 recruitment, using the same cells, drug dilutions, and assay buffers [1% dimethylsulfoxide (DMSO), F12 Ham’s buffer] to ensure accurate assay-to-assay comparisons of data. Plates were read using a time-resolved fluorescence ratio (665 nm/620 nm) on a PheraStar plate reader
