How to take, the dosage

Over the mouth, gradually crumbling.

Adults and children over 12 years of age with a body weight of at least 50 kg

Taking 1-2 tablets 4-6 times a day about 1 hour after meals and before going to bed, but not more than 8 tablets a day. The duration of use is not more than 2 weeks.

Similar doses are recommended for the treatment of heartburn regardless of meals.

Adults and children over 12 years of age with body weight less than 50 kg, children aged 6 to 12 years

Patients with CKD

Dose adjustment is not required. The duration of treatment is not more than 2 weeks.

Interaction

When used concomitantly, the drug Gastal® increases the activity of levodopa and nalidixic acid, reduces and delays absorption of quinolones, isoniazid, naproxen, iron drugs, indomethacin, aminazine, beta-adrenal blockers, diflunisal, H2-histamine receptor blockers, fat-soluble vitamins, indirect anticoagulants, barbiturates.

In interaction with metal ions from antacids, tetracyclines form insoluble chelate complexes; as a result of this interaction, absorption of tetracyclines is reduced by more than 90%. Simultaneous administration of these drugs is not possible. If combined administration is necessary, tetracycline should be taken at least 2 hours before taking the antacid.

In the presence of aluminum and magnesium hydroxides contained in the antacid, absorption of ciprofloxacin and ofloxacin is reduced by 50-90%.

The bioavailability of captopril is significantly reduced in the presence of antacids, and the combined use of antacids and metoprolol leads to decreased plasma concentrations of metoprolol.

The concomitant use of high doses of antacids may reduce the absorption of ranitidine by 10-33%.

The use of antacids does not affect the bioavailability of amoxicillin, cephalexin and the combination of amoxicillin and clavulanic acid, but may significantly reduce the absorption of doxycycline from the GI tract.

Elevated urinary pH on antacid therapy may increase tubular reabsorption of basic (alkaline) drugs and decrease reabsorption of acidic compounds. Antacids may decrease and slow absorption of salicylates, including acetylsalicylic acid, and by increasing urinary pH may promote faster urinary excretion of salicylates from the body, with an accompanying 30-70% decrease in their serum concentrations.

The absorption of cardiac glycosides, including digoxin and digitoxin, when used concomitantly with antacids is not significantly reduced.

M-cholinoblockers, by slowing gastric motility, increase the duration of action of the drug Gastal®.

In order to prevent possible interaction of the drug Gastal® with other drugs it is recommended to take it 1 hour before or 1 hour after their administration.

Special Instructions

Lower doses and shorter periods of treatment are indicated for underweight adults (less than 50 kg) and children.

The recommended doses and duration of treatment should not be exceeded when used in patients with impaired renal function.

Continuous use for more than 2 weeks is possible only after consultation with a physician.

Impact on the ability to drive or perform work requiring increased speed of physical and mental reactions. Administration of the drug Gastal^® does not affect the ability to drive and operate other machinery.

Contraindications

• High sensitivity to aluminum salts, magnesium or other components of the drug
• Severe renal failure
• Alzheimer’s disease
• hypophosphatemia
• lactose intolerance, lactose deficiency, or lactose and glucose deficiencyAlzheimer’s disease;
• hypophosphatemia;
• lactose intolerance, lactase deficiency or glucose-galactose malabsorption;
• children under 6 years of age.

With caution: in chronic renal failure (CKD), pregnancy and breastfeeding, adults and children over 12 years of age with a body weight less than 50 kg, children from 6 to 12 years of age, the elderly.

Side effects

When using the drug in the recommended doses, adverse reactions are rare (at least 0.01%, but less than 0.1%): nausea, constipation, diarrhea, changes in taste.

In exceptional cases allergic reactions are possible.

Overdose

Symptoms of acute overdose are not described.

With long-term use of high doses of drugs containing aluminum and magnesium, hypophosphatemia, hypocalcemia, hypercalciuria, osteomalacia, osteoporosis, hypermagnesemia, hyperaluminemia, encephalopathy, nephrocalcinosis and renal dysfunction may develop. The development of more pronounced adverse reactions from the gastrointestinal tract (GIT) (constipation, diarrhea), in patients with renal failure – thirst, decreased blood pressure, hyporeflexia is possible.

Treatment: symptomatic therapy.
