[Effects of magaldrate on circadian profile of gastric juice pH in medical intensive care patients (author's transl)].

The effect of the antacid magaldrate on intragastric pH behaviour was investigated in 9 medical intensive care patients. During the 24-hour test period 10 ml of this complex preparation induced pH increases to values between 6 and 7 when it was administered every two hours. However, three-hourly administration of 15 ml magaldrate did not result in a sufficient intragastric pH increase. Thus relatively small volumes of magaldrate are sufficient to neutralize gastric acid of these intensive care patients effectively.
