A novel particulate composite hydrotalcite which offers antacidic effect comparable to that of a particulate hydrotalcite so far used as a gastric antacid and, further, offers excellent stomach inner wall protection effect. A particulate composite hydrotalcite represented by the following formula (1), (MgaZnb)1-xAlx(OH)2(An−)x/n.mH2O (1) wherein An−is CO32−, SO42−or Cl−, n is 1 or 2, and x, a, b and m are values that satisfy the following conditions, 0.18≰x≰0.4, 0.5≰a<1, 0<b≰0.5, 0≰m<1, and a gastric antacid using the particulate composite hydrotalcite as an effective component. When used as a gastric antacid, the particulate composite hydrotalcite suppresses the occurrence of damage in the mucous membranes of stomach and intestines.
