Because opioids avimza dopamine levels in the brain, they produce a pleasurable sensation, which is felt to be addictive. Therefore, most of these products must be swallowed pckage and never broken, chewed, crushed or dissolved, due to the risk of rapid opioid release and absorption of potentially fatal doses. Distribution Once absorbed, morphine is distributed to skeletal muscle, kidneys, liver, intestinal tract, lungs, spleen and brain.

The inhibition of GABA allows dopaminergic neurons to fire more vigorously, and the extra dopamine in the nucleus accumbens is intensely pleasurable.

The effective terminal half life of morphine after IV administration is reported to be approximately 2 hours.

There are no adequate and well-controlled studies in pregnant women. Long-acting opioids for chronic pain; pharmacotherapeutic opportunities to enhance compliance, quality of life, and analgesia.

Extended-release morphine sulfate in treatment of severe acute and chronic pain

No formal nonclinical studies to assess the potential of morphine to impair fertility have been conducted. A randomized, double-blind trial. Chem Commun Camb ; Author information Article notes Copyright and License information Disclaimer. Flush the empty capsule down the toilet right away See Figure 4. Additionally, sustained-release morphine has also been linked to improvement in quality of life and sleep. The acidity of the stomach causes the polyethylene glycol component of the polymer coating to start to dissolve, forming pores that allow GI fluid to enter the pellets and dissolve the morphine sulfate, which can then diffuse and be absorbed into the body.


Because of the pellet formulation, the capsules can be opened and sprinkled on apple sauce. Dose can be increased every 3 to 4 days using increments of 30 mg. However, in a recent systematic review of long-acting versus short-acting opioids, 24 Rauck noted that, while it was clear that long-acting opioids achieved more stable drug levels, there was no clear evidence from appropriately designed comparative trials to make a case for the use of one type of formulation over the other on the basis of clinical efficacy.

Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that develop after repeated substance use and include: Morphine can reduce the efficacy of diuretics by inducing the release of antidiuretic hormone.

Gastric, biliary, and pancreatic secretions are decreased by morphine. Patients who experience breakthrough pain may require a dose increase of AVINZA, or may need rescue medication with an appropriate dose of an immediate-release analgesic.


In the hamster, morphine sulfate given subcutaneously on gestation day 8 produced exencephaly and cranioschisis. The benefit of analgesia, therefore, must always be balanced with the risk of addiction and overdose.

As a result, drug release is independent of the pH of the surrounding GI environment. Crushing, chewing, or dissolving the pellets in AVINZA capsules will result in uncontrolled delivery of morphine and can lead to overdose or death [see Warnings and Precautions 5. The range of dose strengths available may not be appropriate for treatment of very young pediatric patients.

In general, begin with half of the estimated daily morphine requirement as the initial dose, managing inadequate analgesia by supplementation with immediate-release morphine.

Randomized, double-blind evaluation in patients with chronic back pain. Once administered, the sodium and potassium ions present in the GI tract fluid gradually displace morphine from the resin. The mean peak concentration was The morphine in AVINZA avinsa aggravate convulsions in patients with convulsive disorders, and may induce or aggravate seizures in some clinical settings.

If the level of pain increases after dose stabilization, attempt to identify the source of increased pain before increasing the AVINZA dose. Effects on the Cardiovascular System. Med Clin N Am. The most obvious is convenience, which leads to improved patient compliance.
