placebo

[L.] a substance given to a patient as medicine or a procedure performed on a patient that has no intrinsic therapeutic value but pleases the patient's owner who expects to have to give the animal some medicine. A placebo may be administered in the form of a sugar pill or an injection of sterile water.

Placebos are also used in controlled clinical trials of new drugs. While some patients selected at random are given the new drug, others are given a placebo. Often this is an active placebo that mimics the new drug's side-effects. Neither the patients nor the veterinarians know who is receiving the real drug. The patients taking the new drug must have significantly more relief of signs than the control group taking the placebo for the new drug to be considered to be effective. Placebos can produce an effect that is either positive, with improvement of signs, or negative, with worsening of signs or the appearance of adverse side-effects.
