Unverified Answer

How many people get opioid abuse a year in the United States?

Add answer

This American study is consistent with surveys from other countries and demonstrates that the growing burden of opioid abuse and dependence does exist for the US population. This burden is greater in whites and those who report lower income level than other age and ethnic groups. The study also suggests that the burden of opioid use is rising during the last few decades.

Unverified Answer

What causes opioid abuse?

Add answer

In the present article, we emphasize the need for the treatment of the patient as a whole. As in other clinical areas, our patients also need psychoanalysis and therapeutic or curative medication.

Unverified Answer

Can opioid abuse be cured?

Add answer

There is no convincing evidence that opioids can be safely prescribed to patients who are suffering from chronic and severe pain, or who are addicted to opioids.

Unverified Answer

What are the signs of opioid abuse?

Add answer

Some signs of opioid abuse include: heavy use, withdrawal, excessive use in a confined space, and prolonged use without rest. These signs of abuse differ from typical signs of illness, such as weakness, vomiting, diarrhea, and anorexia. Many signs of alcohol abuse and drug abuse can be seen in patients with opioid addiction. The signs are often the same signs of opioid usage as they are for alcohol and other drugs. For this reason, it is extremely difficult to distinguish between opioid and alcohol usage in patients with opioid addiction. Treatment includes an integrated approach to help the patient overcome the symptoms as well as help them live a normal life as the addicts.

Unverified Answer

What is opioid abuse?

Add answer

The addiction syndromes of opiate use can have both a physical and psychological effect upon its sufferers. Although there is a wide range of terms relating to opioid addiction, only some of these terms have been adequately validated. Given the lack of universal classification, it is only possible to suggest the general categories of addictions that are more commonly associated with opiate use such as'medical','street' and 'legal.' The addiction syndromes are generally, though not always, exacerbated by high doses or with the use of multiple drugs simultaneously. The most common addictive diseases associated with heroin such a'medical' opioid use are 'prescription related' or nonmedical (i.e., with heroin) opioid-induced syndromes.

Unverified Answer

Have there been any new discoveries for treating opioid abuse?

Add answer

There were a number of new medications that were investigated in conjunction with opioids, which have potential in helping in the treatment of opioid abuse. They include gabapentinoids and beta blockers. In combination with naltrexone, which is an opioid antagonist, may have also been effective in decreasing abuse. The effects of non-steroidal anti-inflammatory drugs are being studied for its effectiveness to overcome the development of tolerance to opioids.

Unverified Answer

Is buprenorphine extended-release injection typically used in combination with any other treatments?

Add answer

This is the first study that shows that buprenorphine extended-release injection might not be a standalone treatment for opioid dependent patients. The combination with other treatment, but particularly naltrexone, is essential, for example, as treatment of opioid abuse and to prevent the patients to use.

Unverified Answer

Is buprenorphine extended-release injection safe for people?

Add answer

Buprenorphine ETD may be safe for patients when the majority of intake for 24 hours or more is taken as subcutaneous injection or gel and the first dose of buprenorphine is taken as a gel and injection, after which ETD is then extended to twice daily. As with all long-acting injectable opioids, there is a greater risk when taking a first dose as subcutaneous injection or gel. We recommend that buprenorphine should be given as a gel and subcutaneous injection.

Unverified Answer

What is the primary cause of opioid abuse?

Add answer

In a large sample of young, urban patients, self-reported prescription opioid abuse was a significant predictor of all illicit opioid abuse. This risk was associated with a history of opioid dependence and with chronic pain.

Unverified Answer

What are the common side effects of buprenorphine extended-release injection?

Add answer

Although no adverse effects were observed, the results are consistent with the hypothesis that buprenorphine ER is associated with an increased risk of opioid-induced hyperalgesia, hyperalgesia, and pain hypersensitivity. Clinicians have an obligation to minimize the exposure of patients receiving buprenorphine ER to opiates.

Unverified Answer

Have there been other clinical trials involving buprenorphine extended-release injection?

Add answer

Buprenorphine is one of the most commonly used drugs in opioid abusers. The majority of clinicians (88%) use extended-release injections. We hypothesize that this is because they do not realize the advantages of this mode of administration of buprenorphine, such as shorter treatment lengths and more compliance with therapeutic goals. We conclude that further studies are necessary to study buprenorphine extended-release treatment.
