Influence of sulpiride on gastrointestinal motility: experimental radiological study in the dog.
A radiological study has been carried out in the dog to control the influence of N-ethyl-2(2-methoxy-5-sulfamido-benzamidomethyl)-pyrrolidine (sulpiride) on the motility of the gastrointestinal tract. The drug was administered orally and parenterally at different doses for each pharmaceutical form and for such route of doses for each pharmaceutical form and for each route of administration. In doses which were considered optimal, the results have demonstrated that sulpiride exerts hypertonic and hyperphasic effects on the smooth musculature of the gastrointestinal tract. Consequently, there is a reduction of the transit time and of the emptying of the opaque meal in the various sectors of the gastrointestinal tract, which is in the order of about 50% with respect to normal. Using doses which are inferior to those considered optimal, no significant results were obtained, while following higher doses the action of sulpiride is manifested by an inhibitory effect on gastrointestinal motility.
