title: An antacid comparison trial.
abstract: A trial is described in which patients going into labour were randomly allocated to treatment with either Andursil or Magnesium Trisilicate Co. Following delivery of the baby the stomach is emptied and the volume and pH are measured. Table 5 summarizes the results of 1106 patients. Andursil was found to be more palatable by patients than was Magnesium Trisilicate Co, but the incidence of nausea and vomiting was similar in the two groups.
