ATC Code
B - Blood and blood forming organs
QB - Blood and blood forming organs
Mechanism of ActionIT NEUTRALIZES EXCESS ACID OF STOMACH BUT PRODUCES NO EXCESS ALKALINIZATION OF SYSTEM. IT HAS MILD LAXATIVE ACTION.
Metabolism/Metabolites
...A new component of calculi, trimagnesium orthophosphate /is described/. In a microscopical study of thin sections from 3,500 urinary calculi we detected this compound in 14 stones, all of which contained struvite. New data suggest that trimagnesium orthophosphate is a transformation product of struvite. This well-crystallized substance was always detected a few days after the surgical extraction of struvite kidney stones, in contrast to the newberyite that appears on the surface of very old removed stones or after long exposure of stones to the atmosphere.
