| name | Magnesium Hydroxide Antacid Laxative |
| classification | Antacid, Laxative |
| pharmacokinetics | Magnesium hydroxide is primarily absorbed in the small intestine. It forms magnesium ions which are readily absorbed in the small intestine. The drug's laxative effect is due to its osmotic effect, drawing water into the stool. Excretion primarily occurs in the feces, with some excretion via the kidneys. The exact time course varies considerably, depending on the formulation and the dose; general absorption and elimination times are often not well studied in the context of antacids and laxatives. |
