Understanding how opioids work in the brain is essential. Opioids connect to receptors in the brain, then they send signals to the brain of the opioid effect which blocks pain, slows breathing, and has a general calming and anti-depressing effect. The chemical structure of opioids mimics that of a natural neurotransmitter which is why the activation occurs. However, opioids are unable to activate nerve cells as natural neurotransmitters do, leading to abnormal messages being transmitted through the synapses ("How do opioids work in the brain?", 2018).

"Buprenorphine was introduced in the early 1980s as an opioid analgesic in Europe and subsequently for the treatment of opioid addiction in France in 1996" (Pillarisetti & Khanna, 2015). It is a hydrophobic molecule, which carries a complex chemical structure with more than one chiral centers. It is known to be a potent but a partial agonist of μ-opioid receptor, with a high affinity but low intrinsic activity can induce withdrawal in opioid dependent patients that are using full μ-agonists by displacing the opioids from the receptor. Buprenorphine shows high volume of distribution and distributes well in tissues including brain. As stated it is a partial agonist, therefore its job is to deliver very diminished opioid doses to a patient who is addicted to a stronger opioid. Since buprenorphine triggers the opioid receptors in the brain partially, the “highs" are much lower in comparison to those created by full agonists, allowing the individual to gradually come off the pre-existing addiction, while decreasing the opioid withdrawal symptoms. According to National Institutes of Health, Buprenorphine is listed as a Schedule III controlled drug by the U.S. Drug Enforcement Administration. It is believed to have less risk of causing dependence than Schedule II drugs such as methadone, morphine, and oxycodone. The primary side effects of buprenorphine are similar to other μ-opioid agonists such as …show more content…
This is where the reward system within the brain plays a crucial role. Anything that might feel great to us, the brain then releases dopamine and individuals tend to repeat activities that feel fulfilling. However there are chemical substances that trigger the same biochemical handle, producing longings that ended up portion of a repetitive cycle. Unfortunately Suboxone may behave in the same way. During recent studies it was reported that many patients overtime became addicted to Suboxone. The drug was melted and then the liquid solution was injected into the veins, giving very different results. Naloxone activates once it is in the bloodstream, now instead of consuming Suboxone that was a half a partial opioid agonist and half an opioid antagonist, the patient was injecting two opioid agonists. Patients may do this because they want quicker relief from their physical distress (Centers,

Opioid Vs Nonopioids

...A medication called Opioids is another form of treatment that relieves pain. It can reduce the feeling of pain by blocking the pain signals from reaching the brain. There are times when doctors prescribe opioids for treatment. The Center for Disease Control and Prevention, or CDC recommends that patients should receive the lowest effective dosage, and that opioids should be combined with nonopioid therapies, such as physical therapy. When using opioids to relieve pain there are many side effects that go along with it. Some of the side effects include overdose, depression, and addiction. When a patient no longer use opioids they can go through the symptoms of withdrawal. Opioids can affect a person’s brain, because they are attached to proteins...

How Do Opioids Affect The Body

...Effects opioids have on the body What are the effects of opioids on the human body? Are opioids misused more than they are correctly used? How will doctors fix problems created by opioids in the future? Opioids are a class of drugs that include the illegal drug heroin, synthetic opioids such as fentanyl, and pain relievers available by prescription. These medications can help manage pain when prescribed for the right condition and when used properly. But when misused or abused, they can cause serious harm, including addiction, overdose and death. The drugs are chemically related and interact with the opioid receptors on nerve cells in the body and brain. (fda.gov) Although opioid pain relievers are generally safe for short periods of time as prescribed by a doctor, they can be used incorrectly and be abused. An opiate overdose can be reversed with the drug naloxone. Improvements have been made by reducing availability of the prescription. New medications could potentially help many people recover from opioid addiction.(drugabuse.gov)...

...they need to take larger amounts of heroin to get the same effect”. (NIDA research report series, 2005) Heroin is also an opioid drug and with Heroin, it can be snorted, smoked, injected and inhaled. Once heroin substance is administered the pharmacological route involves crossing the blood brain barrier where the permeability of heroin is ten times higher than morphine.  “Once heroin crosses the blood brain barrier, it is hydrolyzed into 6-acetyl morphine and morphine, which then quickly bind to opioid receptors. The “rush” felt by heroin users is the sensation caused by the rapid entry of heroin into the brain and the attachment of 6-acetyl morphine and morphine to opioid receptors.  Opioids in general can change the neurochemical activity in the brain stem causing a depression in breathing.  In the limbic system opioids cause an increase in feelings of pleasure, and have the ability to block pain signals sent through the spinal cord”. (NIDA research report series, 2005) The physiological changes with heroin and other opioid substances stem from long term use of the drug which causes neurochemical and molecular changes in the brain. The biggest change that occurs with dependence and addiction of heroin substances is with the brain circuitry which deals with the wiring and reward pathway of the brain. “Whenever this reward circuit is activated, the brain records that...

Drug overdose is a big ongoing issue throughout the United States. The medication that is supposed to help with pain causes more harm than healing. A temporary fix creates a more permanent problem, “death” rather than a permanent solution. With proper guidelines and stricter regulation on dosage, usage, and physician prescribing, the chances of overdosing and death due to overdose could be decreased over time. The programs in place now are not as effective as they should be, this is seen with the increase in the rate of overdose from prescription drugs.

As with any type of drug, opioid use has a significant effect on the daily life of the user, which in turn, affects their loved ones. Children whose parents are abusing opioids have been proven to be more delinquent, have more mental health problems, and have a higher chance of accidentally overdosing themselves. While it is common to talk about how addiction affects the user or a town, it is less common to discuss how vulnerable children are.

From Alcoholics Anonymous meetings to long term inpatient rehabilitation programs, there are many different choices available to those struggling with addiction. Understanding the nature of each type of addiction and determining the best course of treatment for the individual is important to ensure success. For opioid addiction, maintenance based programs, though controversial, show high rates of treatment retention, reduction in criminality, gainful employment, and improvement in health; offering an alternative to those who have not had success in abstinence based programs. Addiction is a challenging and complicated health issue. It affects people physically as well as mentally and socially, impacting nearly every aspect of life. Families can be torn apart.

So when people become addicted to something they are attempting to soothe pain. Drugs whether, illegal or not are considered painkillers for that very reason. The attempt to escape from pain is what creates more pain. In the past, society viewed drug addiction as a moral flaw.

Pain Killers: a Deadly Addiction

...medications make it possible for people with chronic diseases, injuries or cancer to continue doing the things they enjoy instead of cringing from horrible pain. They also allow comfort for those close to passing and help others heal after surgery. Despite the benefits, millions of prescription pain medications are being over prescribed and misused, creating an epidemic of addicted individuals and causing thousands of deaths each year. There are two types of painkillers: narcotic opioid drugs and over the counter medications such as aspirin and ibuprofen. Aspirin works by going to the site of the pain and blocking pain signals from being sent to the brain. Although we may still have an injury, our body isn't letting our brain know it. Opioids work in a similar manner by blocking pain signals to the brain; however, they also alter the way the pain feels to the brain. This can translate to a feeling of euphoria, reduced inhibitions and a feeling of wellbeing. It is these feelings that drive people to misuse opioids. According to a 2010 study by the National Institute on Drug Abuse, approximately 7 million people in the United States -- or 2.7 percent of the population -- annually abuse prescription drugs (SCIUTO, 2013). Prescription painkiller overdoses killed nearly 15,000 people in the US in 2008. This is more than 3 times the 4,000 people killed by these drugs in 1999 (Injury Prevention & Control, 2011).
