Conclusions
1. Salicyl compounds are readily absorbed from the stomach.
2. Gastric absorption is more rapid with the smaller salicyl molecules and at lower pH’s.
3. Calcium gluconate which does not materially affect the pH of the acetylsalicylic acid solution likewise does not affect the rate of gastric absorption.
4. Sodium bicarbonate and magnesium oxide which raise the pH of the solution inhibit the rate of gastric absorption of acetylsalicylic acid.
5. The rate of intestinal absorption of salicyl compounds is less affected by the pH of the solution than is their rate of gastric absorption.
6. Substances used to protect against gastro-intestinal irritation, such as calcium gluconate, sodium bicarbonate, and magnesium oxide, do not markedly influence the rate of intestinal absorption of acetylsalicylic acid.
7. Sodium salicylate, calcium salicylate and salicylic acid are absorbed from the intestine at a faster rate than is acetylsalicylic acid.
