Gastrointestinal stimulants are drugs that increase motility of the gastrointestinal smooth muscle, without acting as a purgative. These drugs have different mechanisms of action but they all work to move the contents of the gastrointestinal tract faster.
Gastrointestinal stimulants are used to treat gastroesophageal reflux disease and other gastrointestinal conditions where gastrointestinal movement is slowed.
