Definitions

  • the invention relates to an antacid and/or adstringent and absorbent pharmaceutical preparation containing at least one aluminium compound, as well as a process for the production of such preparations.
  • aluminium-based e.g. aluminium hydroxide, magnesium-aluminium-hydrate, magaldrate etc.
  • oral suspension oral suspension
  • Another ob- ject of the invention relates to the provision of a pharma ⁇ ceutical preparation with sustained release of the antacid and/or adstringent and absorbent compounds.
  • the principle of the invention is a phosphate delivery system controlled by the swelling mechanism of the hydro- colloid.
  • Fig.1 the top left rectangle symbolizes the magaldrate example.
  • Excess acid (AC) in the gastric fluid is neutralized (N) by the OH ⁇ -flux.
  • the resulting Al3 + - flux is bound by the phosphate P and the swelled (arrow B) hydrocolloid HY to the phosphate/hydro- colloid/aluminium system (PHAS) .
  • the phosphate/ hydrocolloid system (P+HY) controls the dissolution and binding of the aluminium as shown in
  • Fig.2 (left of the dotted line: stomach ST; right of the dotted line: intestines IN) partly through an oscil ⁇ lating reaction mechanism influenced by the change of the intragastric pH-value, partly by binding the aluminium to the hydrocolloid, advantageously to a crosslinked polymer.
  • Fig.3 shows the principle of the aluminium capture based partly on the significant difference in the solubility of aluminium hydroxide and aluminium phosphate; partly, it is also based on the function of the hydrocolloid-phosphate system, which binds the aluminium and is activated by the swelling of the hydrocolloid.
  • the described aluminium capturing system does not decrease the acid neutralization ca ⁇ pacity of the aluminium compound at the acidic pH of the stomach (ST) but inhibits the absorption of alu- minium from the stomach (ST) and the duodenum (inte ⁇ stines (IN) , see Fig.2) of higher pH.
