of prophylactic Magnesium Trisilicate Mixture

Magnesium Trisilicate Mixture BPC has been titrated against a solution representing a high average gastric acid secretion. The results suggest that the 2-hourly administration of 10 ml of antacid is insufficient to maintain the intragastric pH above 3.0, but that 15 ml of the antacid given 2-hourly will ensure that the pH of the gastric contents will be kept above 3.0, and thus that, if such contents are aspirated, the acid-aspiration syndrome will not develop. It is now well appreciated that the chemical bronchopneumonia which characterizes the acid-aspiration syndrome occurs only if the aspirated material has a pH less than 3.0-2.5 (Banniste
