(Roman Catholic Church) vespers of the office for the dead an innocuous or inert medication; given as a pacifier or to the control group in experiments on the efficacy of a drug
placebo, inert chemical substance used instead of a DRUG Placebos contain no medicine, but many patients show medical improvement when given a placebo or an ineffective treatment, a result known as the placebo effect Because of this, placebos are used as controls in drug testing to assure unbiased, reliable results In double-blind studies, both patient and doctor do not know whether a placebo or drug is administered A traditional placebos lack of side effects, however, often identifies it, so an older drug is sometimes used in drug tests instead of or in addition to a placebo 1
An inactive substance or treatment given to satisfy a patient's expectation for treatment In some controlled trials (particularly investigations of drug treatments) placebos that are made to be indistinguishable by patients (and providers when possible) from the true intervention are given to the control group to be used as a comparative basis for determining the effect of the investigational treatment
An inactive substance administered to some study participants while others receive the agent under evaluation, to provide a basis for comparison of effects
A comparison substance against which experimental drugs are sometimes compared A placebo traditionally is an inactive substance resembling the experimental treatment In placebo-controlled trials, the control group takes placebo, while the test group takes the experimental drug Either group may receive a standard therapy in addition Many placebo-controlled trials are also double-blinded, which means that neither doctors nor patients know who is receiving drug or placebo
An inactive substance containing no medicine, commonly referred to as a "sugar pill " It looks, smells, and tastes just like a drug being tested, and is used as a control in clinical trials
A placebo is an inactive substance which may look like medicine but contains no medicine - a "sugar pill" with no treatment value In some studies, the participants in a control group may be given a placebo
An inert substance such as a sugar pill, that is used as the "treatment" for one arm of a randomized trial, typically a double blind randomized trial In many cases where the treatment causes obvious side effects, a placebo cannot sensibly be used If there is no effective standard treatment, the control group may simply get no treatment, other than observation and measures to control symptoms as appropriate In this case, members of the control group will know that they are in the control group A very great myth about randomized cancer clinical trials is that the patients in one arm always get just a placebo The truth is that whenever there is a standard treatment the investigators think may be effective, the control group will at least get that treatment
– A chemically inert substance given in the guise of medicine for its psychologically suggestive effect; used in controlled clinical trials to determine whether improvement and side effects may reflect imagination or anticipation rather than actual power of a drug
A placebo is a substance with no effects that a doctor gives to a patient instead of a drug. Placebos are used when testing new drugs or sometimes when a patient has imagined their illness
