Pharmacotherapeutic Group

Antacid agent

Pharmacological Action

Antacid drug. Contains Calcium Carbonate and Magnesium carbonate, which provide rapid and prolonged neutralization of excess hydrochloric acid in gastric juice, thereby exerting a protective effect on the gastric mucosa.

Achievement of the therapeutic effect within 3-5 minutes is due to the good solubility of the tablets and the high calcium content.

Pharmacokinetics

As a result of the interaction of the drug 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. Maximum absorption is 10% for calcium and 15-20% for magnesium.

A small amount of absorbed calcium and magnesium is excreted by the kidneys. In the intestine, insoluble compounds are formed from the soluble salts, which are excreted in the feces.

Pharmacokinetics in special clinical cases

In case of impaired renal function, the concentration of calcium and magnesium in plasma may increase.

Indications

Symptoms associated with increased acidity of gastric juice and reflux esophagitis: heartburn, sour belching, occasional stomach pain, feeling of fullness or heaviness in the epigastric region, dyspepsia (including those caused by dietary errors, medication use, alcohol abuse, coffee, nicotine); dyspepsia of pregnancy.

Dosage Regimen

The drug is taken orally.

Chew the tablets thoroughly or hold in the mouth until completely dissolved; do not swallow whole.

For adults and children over 12 years, take 1-2 tablets when symptoms appear.

If symptoms persist, repeat the dose after 2 hours.

Do not exceed a maximum daily dose of 11 tablets.

For dyspepsia of pregnancy, adhere to the standard adult dosage.

To avoid drug interactions, take other medications 1-2 hours before or after taking this antacid.

Do not use for continuous long-term therapy without medical supervision.

Discontinue use and consult a physician if symptoms worsen or do not improve.

Adverse Reactions

Allergic reactions very rarely – rash, angioedema, anaphylactic reactions.

When the recommended doses are followed, the drug is well tolerated.

Contraindications

Severe renal failure; hypercalcemia; hypophosphatemia; nephrocalcinosis; children under 12 years of age; sucrase/isomaltase deficiency, fructose intolerance, glucose-galactose malabsorption syndrome; hypersensitivity to the components of the drug.

Use in Pregnancy and Lactation

When used in recommended doses, the drug does not pose a danger to the fetus or child.

Use in Renal Impairment

Contraindicated in severe renal failure, nephrocalcinosis.

Pediatric Use

Contraindicated for use in children under 12 years of age.

Special Precautions

When prescribing the drug to patients with impaired renal function, the concentration of magnesium, phosphorus, and calcium in the blood serum should be regularly monitored.

Patients with impaired renal function are not recommended to take the drug for a long time in high doses.

Use of the drug in high doses may increase the risk of kidney stone formation.

Effect on the ability to drive vehicles and machinery

The use of the drug does not affect the ability to perform potentially hazardous activities that require increased concentration and speed of psychomotor reactions.

Drug Interactions

A change in the acidity of gastric juice caused by taking antacids may lead to a decrease in the rate and extent of absorption of other drugs taken simultaneously, therefore medications should be taken 1-2 hours before or after taking antacids.

With simultaneous use, antacids reduce the absorption of antibiotics of the tetracycline group, fluoroquinolones, cardiac glycosides, levothyroxine, iron preparations, phosphates, fluorides.

With simultaneous use with thiazide diuretics, the concentration of calcium in the blood serum should be regularly monitored.

Storage Conditions
