Oxycodone: Chemical | Organic composition
Last modified: Saturday, 20. June 2009 - 2:31 pm
Oxycodone is available alone or in combination with either acetaminophen or aspirin. Its chemical structure is most closely related to codeine, but it has strong painkilling effects equal to those of morphine.
Types of prescription oxycodone
Oral preparations of oxycodone include immediate-release pills, controlled-release pills, and a liquid solution. The immediate-release pills, as their name implies, get the drug into the bloodstream faster than other formulations. Within about 15 minutes of taking immediate-release oxycodone, the drug’s analgesic effects take hold. Pain is lessened and the user experiences a feeling of drowsiness and/or well-being.
The controlled-release formulations, on the other hand, prolong the release of oxycodone from the tablet for several hours. These pills have a special protective outer coating that makes them harder to digest, so that the oxycodone inside can be released slowly over a period of about 12 hours. That means the pills are capable of providing relief that lasts twice as long, allowing users to obtain the same effect they would get from taking an immediate-release tablet once every six hours.
For patients with severe pain, one additional advantage of newer controlled-release formulations such as OxyContin is that they contain a much larger amount of oxycodone than the other prescription painkillers that contain some oxycodone.
Oxycodone with aspirin
Like oxycodone, oxycodone with aspirin is used to treat moderate to severe pain. The aspirin provides additional pain relief and anti-inflammatory properties not found in oxycodone alone. For some types of pain, these medications may be a better choice than oxycodone alone, particularly if pain is accompanied by significant inflammation, swelling, and stiffness. The aspirin component also may be especially beneficial if pain is accompanied by fever.
Pain relief usually begins within 30 minutes of taking oral oxycodone with aspirin. The drug achieves its peak effect within about 90 minutes and lasts for three to four hours.
Oxycodone with acetaminophen
Like oxycodone with aspirin, oxycodone with acetaminophen combines a powerful pain reliever with an additional pain reliever and a fever-reducer. However, unlike aspirin, it does not have anti-inflammatory properties, so it may not be the best medication if a patient’s pain is accompanied by inflammation, swelling, and stiffness.
Pain relief usually begins within 30 minutes of taking oxycodone with acetaminophen. The drug achieves its peak effect within about 90 minutes and lasts three to four hours.
