Pharmacodynamics and pharmacokinetics


Refers to the group of antacid preparations. Includes magnesium carbonate and calcium carbonate, providing rapid and long-term neutralization of excess amount of hydrochloric acid in the composition of gastric juice. Has a protective effect on the gastric mucosa.
Achieving a therapeutic effect within three to five minutes is due to the rapid solubility of chewable tablets and a high calcium content.


After the interaction of Rennie with gastric juice, magnesium and calcium salts are formed. The degree of absorption of these salts depends on the dose used. The maximum degree of absorption is up to 20% of magnesium and up to 10% of calcium.
A small amount of absorbed calcium and magnesium ions are excreted by the kidneys. In the intestine of soluble derivatives of the preparation insoluble substances are formed, which are excreted with feces.

Indications for use

Symptoms caused by high acidity of gastric juice and reflux esophagitis (including those caused by medication, dietary error, abuse of coffee, alcohol or nicotine):
    periodic epigastric pain;
    feeling of heaviness or overflow in the stomach;

Rennie, Instructions for Use (Method and Dosage)

Instructions for use Rennie recommends chewing or keeping chewable tablets in their mouth until they dissolve completely.
Adults and children under 12 years of age (unless otherwise prescribed by the attending physician) take 1 or 2 tablets with the development of the above symptoms. If it is necessary to repeat the use of the drug no earlier than 2 hours.
The maximum safe daily dose of the drug is 11 tablets.


Prolonged use of the drug in large doses in patients with kidney damage can lead to the development of alkalosis, hypermagnesemia, hypercalcemia, which are manifested by vomiting, nausea and muscle weakness. In such cases, you should stop taking the drug and seek help from your doctor.


Reducing the acidity of gastric juice due to the use of antacids leads to a decrease in the degree and rate of absorption of other drugs used simultaneously. Therefore, pharmaceutical preparations must be taken an hour and a half before or after taking Renny.
When combined, antacids reduce the absorption of fluoroquinolones, tetracycline-type antibiotics, levothyroxine, cardiac glycosides, phosphates, iron preparations, fluorides.
When used simultaneously with thiazide diuretics, it is recommended that the content of calcium ions in the blood be monitored regularly.
