What is a placebo in a drug study?
Because a placebo isn’t an active treatment, it shouldn’t have a significant effect on the condition. Researchers can compare the results from the placebo to those from the actual drug. This helps them to determine if the new drug is effective. You may be familiar with the term “placebo” in reference to something called the placebo effect.
What information should be included in patient education about placebo therapy?
If applicable, subjects must be informed of any viable medical alternatives to being placed on placebo. The duration of time that a subject will be on a placebo, degree of discomfort, and potential effects of not receiving medication must all be explained. Any consequences of delayed active treatment must be explained to the subjects.
How many patients are concerned about the possibility of receiving placebo?
In a hypertension trial, 24% of the patients were concerned about the possibility of receiving a placebo. Whilst the proportion of subjects who might receive placebo influenced patient enrolment decisions it was not a key determinant of recruitment efficiency [13].
Which medical specialty contributes the most to the placebo effect?
Oncology (15.0%), cardiology (14.2%), and neurology (13.1%) made the greatest contributions. A review of the informed consent forms showed that placebo was described in a similar manner in most studies: the explanation was limited to between four and eight words.
What is the group that receives a placebo called?
control groupA control group is an experimental condition that does not receive the actual treatment and may serve as a baseline. A control group may receive a placebo or they may receive no treatment at all.
Who gets the placebo in an experimental study?
Placebos are used in some clinical trials to help researchers determine if an investigational therapy is effective. In a placebo-controlled trial, a control group receives a placebo, while a treatment group (a.k.a., experimental group) receives the treatment being studied.
In what type of study are participants given a placebo?
Placebo-controlled studies are a way of testing a medical therapy in which, in addition to a group of subjects that receives the treatment to be evaluated, a separate control group receives a sham "placebo" treatment which is specifically designed to have no real effect.
Is placebo group same as control group?
In order to make sure a new drug or vaccine is effective, studies often use a placebo or control group. Placebos are “sugar pills” or “dummy drugs” with no active ingredients and are made to look like the real medicine. A control is a standard treatment (that may be currently used) for the illness.
Is a placebo considered an independent variable?
When a researcher gives an active medication to one group of people and a placebo, or inactive medication, to another group of people, the independent variable is the medication treatment. Each person's response to the active medication or placebo is called the dependent variable.
What is placebo clinical studies?
A placebo is an inactive substance that looks like the drug or treatment being tested. Comparing results from the two groups suggests whether changes in the test group result from the treatment or occur by chance.
What is a placebo in experimental research quizlet?
Placebo treatment: A fake treatment that we know has no effect , except through the power of suggestion. For example, in medical experiments, a participant may be given a pill that does not have a drug in it.
Why is a placebo group included in clinical trials?
A placebo (pluh-SEE-bow) is a treatment that looks like a regular treatment, but is made with inactive ingredients that have no real effect on patient health. Placebos are used in some types of clinical trials to help make sure results are accurate.

Protocol and Consent Form Requirements for Placebo Washout Periods
Studies that involve washout periods (with or without the use of a placebo) present similar concerns about risk to subjects as studies using placebos because both involve withholding available therapy from subjects.
