MAALOX TC 300 mg + 600 mg chewable tablets
Why is Maalox TC used? What is it for?
For the prevention of stress-induced gastroduodenal bleeding.
As an antacid in the symptomatic therapy of heartburn and epigastric pain associated with peptic ulcer or other gastrointestinal pathology, where a high neutralizing capacity is required.
Contraindications When Maalox TC should not be used
Hypersensitivity to the active substances or to any of the excipients.
Contraindicated in patients with porphyria. Severe forms of renal insufficiency (creatinine clearance less than 30 mL / min).
Generally contraindicated in pediatric age. State of cachexia (state of general decay of the organism).
Precautions for use What you need to know before taking Maalox TC
Do not take more than 3 tablespoons / 3 sachets (45 ml) of suspension or 9 tablets in 24 hours or this dosage for more than 2 weeks or use the product in case of kidney disease unless on medical advice.
Interactions Which drugs or foods can modify the effect of Maalox TC
Tell your doctor or pharmacist if you have recently taken any other medicines, even those without a prescription.
Since Al and Mg salts reduce the gastrointestinal absorption of tetracyclines, it is recommended to avoid taking MAALOX TC during oral tetracycline therapy.
The use of aluminum-containing antacids may reduce the absorption of drugs such as H2-antagonists, atenolol, cefdinir, cefpodoxime, chloroquine, tetracyclines, diflunisal, digoxin, bisphosphonates, ethambutol, fluoroquinolones, sodium fluoride, glucocorticoids, indomethacine, is ketoconazole, levothyroxine, lincosamides, metoprolol, phenothiazine neuroleptics, penicillamines, propranolol, rosuvastatin, iron salts.
- Polystyrene sulphonate (Kayexalate) Caution is advised when the medicinal product is taken together with polystyrene sulphonate (Kayexalate) due to the risk of reduced efficacy of the resin in binding potassium, of metabolic alkalosis in patients with renal impairment (reported with aluminum hydroxide and hydroxide of magnesium), and intestinal obstruction (reported with aluminum hydroxide).
- Aluminum hydroxide and citrates can cause an increase in aluminum levels, especially in patients with renal impairment.
Allow at least two hours (4 for fluoroquinolones) before taking MAALOX TC to avoid interaction with other drugs. The concomitant use of quinidine can lead to an increase in serum quinidine levels and lead to an overdose of quinidine. .
The simultaneous use of aluminum hydroxide and citrates can lead to an increase in aluminum levels, particularly in patients with renal insufficiency.
Warnings It is important to know that:
Aluminum hydroxide can cause constipation and an overdose of magnesium salts can cause bowel hypomotility; high doses of this medicine can cause or aggravate intestinal obstruction and ileus in patients at higher risk, such as those with renal impairment, with underlying constipation, with impaired intestinal motility, in children (0 to 24 months) , or elderly.
Aluminum hydroxide is not well absorbed from the gastrointestinal tract, and systemic effects are therefore rare in patients with normal renal function.
However, excessive doses or long-term use, or even normal doses in patients with low phosphorus diets or in children (0 to 24 months), can lead to phosphate elimination (due to an aluminum-phosphate bond) accompanied by an increase in bone resorption and hypercalciuria (presence of a large amount of calcium in the urine) with the risk of osteomalacia. It is advisable to consult your doctor in case of long-term use or in patients at risk of abnormal reduction of phosphate levels in the blood.
In patients with renal impairment, plasma levels of aluminum and magnesium tend to increase causing hyperalluminaemia (excess levels of aluminum in the blood) and hypermagnesaemia (excess levels of magnesium in the blood).
Therefore, prolonged use of the medicinal product should be avoided in such patients. In these patients, long exposures to high doses of aluminum and magnesium salts may lead to encephalopathies, dementia, microcytic anemia or worsening of osteomalacia due to dialysis.
Aluminum hydroxide may not be safe in patients with porphyria undergoing hemodialysis.
In the presence of severe forms of renal insufficiency it is recommended to take the product under the direct supervision of a doctor. Prolonged use of the medicine should be avoided in these patients. Maalox TC tablets contain sucrose; this should be taken into account in case of diabetes or low-calorie diets. Due to the presence of sucrose, patients with rare hereditary problems of fructose intolerance , glucose-galactose malabsorption or sucrase-isomaltase deficiency should not take MAALOX TC chewable tablets.
Due to the presence of sorbitol both in the oral suspension and in the tablets, patients with rare hereditary problems of fructose intolerance should not take MAALOX TC.
WHAT TO DO DURING PREGNANCY AND BREASTFEEDING
The medicine should only be used when needed, under direct medical supervision, after evaluating the expected benefit to the mother in relation to the possible risk to the fetus or infant. Due to limited maternal absorption when taken according to the indicated dosage (see section "How to use this medicine"), aluminum hydroxide and its combinations with magnesium salts are considered compatible with breastfeeding. Ask your doctor or pharmacist for advice before taking the medicine.
EFFECTS ON THE ABILITY TO DRIVE VEHICLES AND ON THE USE OF MACHINERY
MAALOX TC does not affect the ability to drive or use machines.
Dose, Method and Time of Administration How to use Maalox TC: Posology
Prevention of upper gastrointestinal stress bleeding
Determine the pH of the gastric aspirate, then introduce through a nasogastric tube 10 ml of Maalox TC oral suspension together with 30 ml of water. Check every hour, by aspiration, if the gastric content is at pH> 4. If it is lower , introduce a double quantity of Maalox TC oral suspension with 30 ml of water until a pH> 4 is ensured.
Symptomatic therapy

Overdose What to do if you have taken too much Maalox TC
Experience with deliberate overdose is very limited. Cases of overdose with aluminum salts are more likely to occur in patients with chronic severe renal impairment with the following symptoms: encephalopathy, seizures and dementia, hypermagnesaemia (excessive increase in blood magnesium levels ).
The most frequently reported symptoms of acute overdose with aluminum hydroxide and in combination with magnesium salts include diarrhea, abdominal pain and vomiting.
High doses of this medicine can cause or aggravate intestinal obstruction and ileus in patients at risk (see section "It is important to know that").
As in all cases of overdose, treatment should be symptomatic with generic supportive measures.
Aluminum and magnesium are eliminated by urinary excretion; treatment of magnesium overdose involves rehydration and forced diuresis. In case of renal insufficiency, hemodialysis or peritoneal dialysis is required.
In case of accidental ingestion / intake of a dose of Maalox TC, notify your doctor immediately and go to the nearest hospital.

05.0 PHARMACOLOGICAL PROPERTIES
05.1 Pharmacodynamic properties
Pharmacotherapeutic group: Antacids; ATC code: A02AD01.
The antacid activity is expressed in the stomach where, in suitable doses, the magnesium hydroxide and the aluminum hydroxide neutralize the gastric acid production.
The constipating effect of aluminum hydroxide is counteracted by the laxative effect of magnesium hydroxide, thus allowing to reach highly therapeutic doses also in the treatment of peptic ulcer and in the prevention of stress bleeding in the upper gastrointestinal tract.
05.2 Pharmacokinetic properties
When administered orally, the aluminum hydroxide and magnesium hydroxide react with the hydrochloric acid produced in the stomach to form salts, which are only partially absorbed.
The excretion of the absorbed salts occurs mainly via the urine.
05.3 Preclinical safety data
The toxicological tests on the animal have shown the non-existent toxicity in relation to the therapeutic index. In fact, using the maximum doses compatible with the oral administration methods, in various animal species, it was not possible to demonstrate an acute, subacute harmful action. and chronic.
