Severe acute overdosage may precipitate sodium overload (hypernatraemia or hyperosmolality) and possibly metabolic alkalosis. Symptoms may include restlessness, weakness, thirst, reduced salivation, dizziness, headache and possibly hypotension and tachycardia.

5. PHARMACOLOGICAL PROPERTIES

Go to top of the page
5.1 Pharmacodynamic properties

This product is an antacid.

Sodium bicarbonate ) These react in the glass of water to
Sodium carbonate ) produce sodium citrate, which has antacid
Citric acid ) buffering properties, and carbon dioxide which

facilitates eructation. A slight excess of sodium bicarbonate remains with a small, direct acid neutralising contribution.

5.2 Pharmacokinetic properties

Since the antacid combination acts locally in the stomach and the components are all dissolved, a consideration of their systemic bioavailability and pharmacokinetic behaviour is not appropriate to safety and efficacy considerations.

Residual sodium and citrate ions available for absorption are safely handled by the body and excreted by normal metabolic routes.
