Placebo Effect – Treatment Or Scam?

The placebo effect is a phenomenon where individuals claim to have improved after receiving a fake or nonexistent therapy, i.e., a "placebo."

Introduction

Would you believe me if I say I could treat your headache with an M&amp;M? Well chances are that if that M&amp;M was disguised as a mainstream painkiller, you might believe it and stop complaining about your<a href="https://merisehat.pk/disease/tension-headaches"> headache</a>. That&rsquo;s basically how the magic pill everyone calls a &ldquo;placebo&rdquo; works. 
&nbsp;

Understanding the role of the placebo effect in medical treatment

Although it is possible to heal oneself mentally, the placebo effect is more complex than just happy thinking. The placebo effect is a phenomenon&nbsp;where individuals claim to have improved after receiving a fake or nonexistent&nbsp;therapy, i.e., a &quot;placebo.&quot;

Any positive results they claim, are simply their anticipation that their ailment is being treated. This is because the placebo cannot truly cure any condition. In medicine, a&nbsp;placebo is any chemical, medication, or another form&nbsp;of treatment that has the appearance of being a medical intervention but isn&#39;t. 
&nbsp;

Early clinical trials compared the placebo&rsquo;s effectiveness to a group of patients who did not take any medicine. Currently, it&rsquo;s necessary to have a third group of participants after learning that the basic act of ingesting an empty tablet creates a placebo effect.

Placebos play a crucial role in clinical trials since they are frequently administered to individuals in the control group. The researchers then compare outcomes from the placebo and the actual medication. In other words, a person&#39;s confidence in the value of the treatment causes them to believe that they are feeling better; researchers rely on this belief to assess the new drug&#39;s efficacy. 
&nbsp;

For instance, a new medicine to decrease cholesterol might be administered to some research participants, while others&nbsp;would receive a placebo. No participant in the trial will be aware of whether they received the real treatment or a placebo. The results of the study&#39;s participants after the medication and placebo treatments are compared to assess the new drug&#39;s efficacy and look for any negative effects<a href="#accordion">[2]</a>.&nbsp;Once the medication outperforms a placebo effect,&nbsp;it is approved.

1 in 3 persons reportedly experiences the placebo effect<a href="#accordion">[1]</a>.&nbsp;A placebo can be in the form of a sugar pill, an injection of salt water, or even a bogus surgical procedure. It would not have any therapeutic effects. 
&nbsp;

Numerous factors contribute to the phenomenon, including:

<ul>
	<li>Expectations or beliefs that their health will improve. The placebo effect is more likely to influence those who are motivated and anticipate their treatment to be effective.</li>
	<li>The idea of receiving care as a result of research participation could lower stress levels and release the body&#39;s natural painkillers.</li>
	<li>Classical conditioning or the long-term association people form between a specific action, like taking pills, and beneficial&nbsp;outcomes.</li>
	<li>A strong bond of trust between medical professionals and their patients, or between researchers and study subjects. Reaction to a treatment may be influenced by hearing a knowledgeable specialist they trust speak enthusiastically about it.</li>
</ul>

According to a study on irritable bowel syndrome, patients receiving a placebo benefit 40-50% of the time when they have a good relationship with their healthcare provider<a href="#accordion">[3]</a>. 
&nbsp;

Other possible explanations for a placebo effect can be:

<ul>
	<li>A patient, who had severe symptoms when they signed up for the treatment or clinical trial, felt a visible change during that period. They think it&rsquo;s the meds when, in reality, the symptoms improved on their own during the natural course of the illness.</li>
	<li>A patient, who had high hopes that the new treatment will work, will pay more attention to improvement signs instead of signs that they may be getting worse. 
	&nbsp;</li>
</ul>

Taking a placebo has no known adverse effects. However, there are rare circumstances when a placebo can result in what is known as a &quot;nocebo effect,&quot; or a bad outcome. The same principles apply here: it&#39;s more probable that the person will have a negative consequence when they expect one.

A study found that 76% of the side effects, such as headaches and fatigue, that 45,380 people who received the COVID-19 vaccination or a placebo experienced,&nbsp;weren&#39;t brought on by the vaccine at all. Rather, it was just a nocebo response!<a href="#accordion">[3]</a>.

In another trial, participants were given placebo opioids. Respiratory depression is a common opioid adverse effect. Despite having no active components, the researchers discovered that the placebo medication, nevertheless, caused respiratory depression<a href="#accordion">[4]</a>.

Increases in dopamine and opioid receptor activation have also been linked to significant placebo reactions. These two substances play a part in the brain&#39;s motivation and reward systems. Contrarily, nocebo decreases the activation of opioid and dopamine receptors. Some of these neurological alterations take place in parts of the brain that antidepressant medications frequently target. The 50&ndash;75% placebo response rate in antidepressant trials may be explained by this<a href="#accordion">[4]</a>. 
&nbsp;

<ul>
	<li>Pain</li>
</ul>

The power of a placebo to lessen pain is known as placebo analgesia. It is thought to function in one of two ways: either natural painkillers called endorphins are released, or the person&rsquo;s perception of pain is altered.&nbsp;

Additionally, it has been discovered that genuine analgesics work better when they are administered to a patient who is aware that they are receiving the medication rather than when it is done covertly. The placebo effect can be seen as supporting a real intervention in this situation. 
&nbsp;

<ul>
	<li>Depression</li>
</ul>

Antidepressants are thought to work mostly through the placebo effect. An analysis of eight studies indicated that placebo antidepressants were beneficial over 12 weeks, highlighting the potential long-term effects of placebos. 
&nbsp;

<ul>
	<li>Anxiety</li>
</ul>

Trials for anti-anxiety medications are particularly prone to the placebo effect, which greatly delays the development and testing of new medications. 
&nbsp;

<ul>
	<li>Cough</li>
</ul>

According to a review of clinical trials including cough medicines, &quot;only 15% of the cough reduction is attributed to the active ingredient, and 85% of the cough reduction is related to treatment with placebo.&quot; 
&nbsp;

<ul>
	<li>Erectile Dysfunction</li>
</ul>

Participants in one study were divided into three groups. The first group was informed that they would receive genuine erectile dysfunction therapy, while the second group was informed that they would either receive a placebo or a genuine treatment, and the third group was informed that they would only receive a placebo&nbsp;for erectile dysfunction.

Even though all three groups received placebo starch tablets, they all showed the same amount of significant improvement.&nbsp; 
&nbsp;

<ul>
	<li>IBS</li>
</ul>

According to a meta-analysis, the placebo response rate in IBS patients ranged from 16.0-71.4%. In another trial, the patients showed improvement despite being informed that their treatment would consist of a placebo. 
&nbsp;

<ul>
	<li>Parkinson&rsquo;s Disease</li>
</ul>

According to an analysis of 11 clinical trials, 16% of Parkinson&#39;s patients who were placed in the placebo groups had significant improvements, which often&nbsp;lasted for six months. Dopamine release in the striatum appears to play a role in the effect. 
&nbsp;

<ul>
	<li>Epilepsy</li>
</ul>

In anti-epileptic medication trials, the placebo response ranges from 0-19%. A 50% reduction in their typical seizure frequency was considered a &quot;placebo response&quot; for this trial. 
&nbsp;

Due to its effects on a variety of ailments, doctors utilize placebos for clinical purposes all around the world. According to 2008 Danish research, 48% of doctors had prescribed placebos at least 10 times in the previous year. These placebos were typically vitamins for weariness and antibiotics for viral diseases. In related research of Israeli doctors, it was shown that 60% gave patients placebos to discourage them from asking for unnecessary medication or if they &quot;needed calming.&quot;

There are moral issues with this approach. First, the patient is misled by the doctor. Second, the placebo is still regarded as an effective treatment if it has the desired outcome. Third, by giving a patient a placebo to make them feel better, the accurate diagnosis of a serious illness is being put off; doctors and pharmacists can be accused of fraud. 
&nbsp;

Although there are more morally right uses of placebos in medical practice, there will likely always be arguments for and against their usage, just like in any other ethical debate.

For instance, some burn sufferers may benefit from using placebos. Opioid pain treatment is not always possible due to the respiratory depression it causes. In this case, an injection of saline disguised as a potent painkiller can lessen the patient&#39;s suffering. 
&nbsp;

Conclusion

According to Robert Buckman, a renowned clinical oncologist, &ldquo;Placebos are remarkable medications. They appear to have some impact on almost all symptoms known to man, and they are effective in at least one-third of patients and occasionally as many as 60%. They cannot be taken in an overdose and have no major negative effects. They are, in a nutshell, the world&#39;s pharmacopeia&#39;s most flexible, adaptive, powerful, safe, and affordable medications4.&rdquo;

However, it should be kept in mind that there is still much we don&#39;t know about placebos; studies are continuous, and each year we learn more.
