Why are cimetidine or ranitidine better antacids than sodium bicarbonate or magnesium or aluminium hydroxide ?

Description : Why are cimetidine or ranitidine better antacids than sodium bicarbonate or magnesium or aluminium hydroxide ? 

Last Answer : Ans. If excess of NaHCO3 or Mg (OH)2 or Al (OH)3 is used, it makes the stomach alkaline and thus triggers the release of even more HCl. In contrast, cimetidine or ranitidine prevent the interaction of histamine with the receptor cells in the stomach wall and thus release lesser amount of HCl.
