Symptoms associated with increased acidity of gastric juice and reflux esophagitis (including those caused by errors in diet, medication, alcohol, coffee, and nicotine abuse):
periodic pain in the stomach area,
feeling full or heavy in the epigastric region,

Long-term use of the drug in high doses in patients with impaired renal function can cause hypermagnesemia, hypercalcemia.

Treatment: you should cancel the drug and immediately consult a doctor.
Local antacid preparation. Alka Seltzer Antiacido Tablet® it contains antacid substances-calcium carbonate and magnesium carbonate, which provide fast and long-lasting neutralization of excess hydrochloric acid of gastric juice, thereby having a protective effect on the gastric mucosa. The achievement of a positive effect within 3-5 minutes is due to the good solubility of the tablets and the high content of calcium.
As a result of the interaction of Alka Seltzer Antiacido® with gastric juice, soluble salts of calcium and magnesium are formed in the stomach.
The degree of absorption of calcium and magnesium from these compounds depends on the dose of the drug. The maximum absorption is 10% calcium and 15-20% magnesium. A small amount of absorbed calcium and magnesium is excreted through the kidneys. With impaired renal function, the concentration of calcium and magnesium in the plasma may increase. In the intestine, insoluble compounds are formed from soluble salts, which are excreted with feces.

- Antacids in combinations
Changes in the acidity of gastric juice during the use of antacids can lead to a decrease in the rate and degree of absorption of other drugs when taken simultaneously, so medications should be taken 1-2 hours before or after taking antacids.
Tetracycline antibiotics, fluoroquinolones, cardiac glycosides, levothyroxine, iron preparations, fluorides, phosphates-with the simultaneous use of antacids, reduce the absorption of these drugs.
Thiazide diuretics — when taken simultaneously with antacids, the concentration of calcium in the blood serum should be regularly monitored.
