Novel synthetic hydrotalcite and antacid comprising said synthetic hydrotalcite
Abstract
Abstract A synthetic hydrotalcite having the composition expressed by the formula; A1203.6MgO.CO2.12H20 and having substantially the following diffraction X-ray diffraction analysis: d.A. 7.75, 3.89, 2.59, 2.30, 1.96, 1.53 and 1.50 SAID SYNTHETIC HYDROTALCITE CONTAINING HEAVY METAL IMPURITIES IN AMOUNTS OF UP TO 30 P.P.M., BEING INSOLUBLE OR SUBSTANTIALLY INSOLUBLE WHEN TREATED WITH 1/10 N NaOH at 37* C. for 1 hour, having an acid consuming capacity of at least 240 m1./g, and being characterized by such properties that the time required for the artificial gastric juice to come to have a pH of higher than 3.0 is up to 30 seconds and time during which the pH of the artificial gastric juice is maintained above 3.0 is more than 120 minutes.
