A preliminary in vitro acid neutralizing capacity test of twelve traditional Ayurvedic antacids were performed in this study. Five traditional preparations of ash of conch shell, ash of oyster, ash of pearl, limestone, and ash of cowrie showed high acid neutralizing capacity similar to standard antacid combination of $Al(OH)_3\;and\;Mg(OH)_2$. Among these the ash of conch shell found the highest acid neutralizing capacity. The ash of tamarind and ash of Achyranthus aspera showed moderate acid neutralizing capacity. The acid neutralizing capacity of red ochre; ash of iron; mixture of niter, alum and ammonium chloride; saltpeter; and ash of mica found below the USP 23 limit.

The combined products of antacids(AM) composed of aluminium hydroxide, magnesium hydroxide, and simethicone with a ratio of 1 : 1 : 0.1 and aceglutamide aluminium(AGA) were assayed for the antiulcer activity. The effect of the antacids(AM) in concurrent treatment with AGA was studied in acute gastric lesion induced by Shay's method, stress, ethanol, and indomethacin, in chronic gastric ulcers induced by acetic acid, and in duodenal ulcer induced by mepirizole. In all experimental models, the combined treatment of AM and AGA in the ratio of 2.3:1 showed significant potentiation in inhibition against acute gastric and duodenal ulcer and revealed a significant potentiation of the healing of chronic gastric ulcer.

On the combination of antacid, the pharmacokinetics and gastric adhesion of [$^{14}c$]aceglutamide aluminium complex([$^{14}C$]AGA) were examined in rats. Specially, this study was focused on the drug interaction that the co-administration of antacid may affect the oral absorption and gastric adhesion of aceglutamide aluminium complex(AGA). In the study of the oral co-administration of [$^{14}C$] AGA and antacid(aluminium hydroxide and magnesium hydroxide(AM)), the radioactivity of plasma and urinary recovery was lower than that of [$^{14}C$]AGA alone administered group. However, the cumulative recovery of radioactivity in feces was increased significantly. The comparative bioavailability of [$^{14}C$] AGA from the plasma concentration-time curve and urinary recovery was about 60%. In vitro, the effect of antacid on the gastric adhesion of AGA was not significatly different between AGA and AGA/antacid treatment. And it accorded well with the result of in vivo experiment. In conclusion, on the combination of antacid, the oral absorption of AGA was decreased by the gastric adhesion was not affected in respect of drug interaction.
