Structural Biochemistry/Oxycodone

Oxycodone is a type of analgesic, oral medication used to relieve moderate to severe pain. It was developed in Germany in the year 1916 as an attempt to improve on the existing opioids, drugs derived and used by opium poppy for therapeutic benefits. A few common examples of compounding are non-steroidal anti-inflammatory drugs like ibuprofen and oxycodone with acetaminophen. Numerous brand names include OxyContin, a Purdue Pharma brand for the time-release oral oxycodone variation, Roxycodone, and Xanodyne.

Oxycodone is mainly used to alleviate moderate to severe pain, as well as managing acute chronic pain. It can also be used an alternative to severe diarrhea and irritable bowel syndrome when commonly prescribed drugs do not work effectively.

Dosage and Administration

Oxycodone comes in a variety of forms: as a solution (including concentrated), a tablet, capsule, and long-acting/extended-release. The previous list of oxycodone forms are usually taken with or without food every 4 to 6 hours, depending if the medication is needed for temporary pain or as a regularly scheduled form of medication Always follow the directions on the prescription label and ask a doctor or pharmacist to explain any information that you do not fully understand.

As mentioned before, it can be taken orally or intranasally using intravenous injections or rectally. 60-87% of all Oxycodone usage are through oral administration, with the rest remaining Compared to morphine, it can be 1.5 to 2 times as potent when taken orally. Because of its potency, a doctor will likely start a patient on a low dosage and increase it over time if the pain is not managed. The body can grow accustomed to the medication, and when that occurs the doctor may need to increase the dose.

This medication can be habit-forming, and consequently a patient must not take a larger dose. A patient also cannot take oxycodone more often than prescribed or take it for a longer period of time than recommended by his doctor. Do not stop taking the medication abruptly; you may experience symptoms of withdrawal.

Withdrawal

When a patient suddenly discontinues the medication, he may experience symptoms such as anxiety, panic attacks, insomnia, muscle pain, nausea, fevers, flu-like symptoms (runny noses, sneezing, chills, watery eyes, etc.) and muscle weakness. When withdrawal occurs, the doctor usually decreases the dosage gradually. Most cases of severe withdrawals are associated with those addicted and using Oxycodone illegally. The experience of withdrawals from Oxycodone are unique to each individual due to the differences in metabolism etc. Therefore even with the same amount of dosage, one person might experience a withdrawal much worse than the next man. Withdrawal effects can be diminished by proper detox procedures.

Oxycodone is a powerful drug used by young teens as well as adults. The drug puts users on a advantage high. Since it is a relief medication, it provides users with a calm relief feeling for a few hours as it enters their bloodstream. The tolerance of taking the drug becomes increasingly higher as users ingest the drug more often.

Some of the effects addiction leads to are: constantly thinking about oxycodone, obtaining large amounts of the drug, taking the drug secretly in order to hide it from others from knowing, lying to loved ones, and feeling pain and restless thoughts during nights of sleep.
