[Value of primperan in digestive studies].

The majority of gastro-intestinal investigations cause disturbances of secretion or gastric tonicity and motility, which can interfere considerably with the examination. It is therefore essential for the doctor to prevent these disorders by equilibrating the gastro-intestinal function. Primperan is incontestably the molecule of choice in this field, because of the specificity and the constancy of its action in the gastro-intestinal tract and because of its excellent tolerance.
