Morphine is a very powerful drug and comes in a variety of brand names, such as Avinza. Other derivatives include Kadian, Morphine IR, MS Contin, MSIR and Oramorph SR. As a form of morphine, Avinza is a narcotic pain reliever and is used to treat moderate to severe pain. Avinza is a highly concentrated solution of morphine sulfate.
Avinza is a short-acting form of morphine and is used as needed for pain. When extended relief is necessary, an extended release version is available. This application is generally reserved for those patients needing pain relief around-the-clock. Avinza and other forms are not typically used for treating pain just after surgery unless the patient is already taking the medication.
Avinza is known to be a highly addictive drug and can cause physical and psychological dependence when it is taken for long periods of time. Even those patients taking the medicine by legal prescription can easily increase dosage to achieve the desired effect. Some may even do so without realizing it. This increase can lead to the development of a physical dependence on the drug.
As there is a high propensity for addiction with Avinza, abuse is common. The drug is often used in treating a terminally ill patient to achieve pain relief as the potential of the drug benefits outweigh the threat of dependence. The chance for dependence can be substantially reduced if the patient is monitored in a program of pain to relief-of-pain cycle.
Avinza is absorbed by the body when it is swallowed. In this method, Avinza begins working right away to provide relief from pain in roughly 15-30 minutes. The medication will reach its peak effect in roughly one hour and then will continue to work 2-4 hours. The drug achieves the desired effect by activating certain receptors in the brain that cause pain relief.
Avinza tolerance can build up very quickly and therefore monitoring is imperative. There are a number of effects a person can feel as a result of the Avinza, including lightheadedness, dizziness, sedation, nausea, vomiting, and sweating. To prevent withdrawal syndrome, the medication should never be abruptly stopped.
A long-term user of Avinza is likely to develop a high tolerance for and dependence on the drug. As a result, withdrawal can be a painful process. Withdrawal symptoms can be felt within hours of stopping use of Avinza and can last quite a long time.
Any and all of the following symptoms can occur in the Avinza withdrawal stage:
- Watery eyes
- Widened pupils
- Runny nose
Like many drugs, addiction to Avinza can be life-threatening and it is important to stop taking the medication if it is not used for medicinal purposes or has been used too long. As the withdrawal symptoms can be intense, it is important that those with an addiction discontinue the drug gradually under the care of a board-certified physician.
