Almasilat – Effect, Application & Risks


Almasilat can bind excess gastric acid and is used to treat acid-related stomach problems, heartburn and gastric and duodenal ulcers .

What is almazilate?

Almasilat is an active ingredient that is used to treat acid-related diseases of the stomach and esophagus , with the drug being prescribed mainly for gastritis (inflammation of the stomach lining) and heartburn.

It is an aluminum magnesium silicate and belongs to the group of acid-inhibiting agents. Almasilate is also referred to as a so-called layered lattice antacid and has a characteristic crystal structure. By taking Almasilat, gastric acid is bound and thus rendered harmless for the mucous membrane of the esophagus (gullet).

Pharmacological action

Almasilat is an acid-binding agent and reduces the concentration of stomach acid, which can relieve symptoms such as acid reflux, stomach pain and heartburn. Heartburn occurs when aggressive stomach acid backs up into the esophagus, which can cause tissue damage.Stomach acid then flows back when there is a dysfunction of the sphincter . In addition, heartburn also occurs as a result of delayed gastric emptying or an overproduction of gastric acid. Backflow of stomach acid can also occur during pregnancy , as the unborn child often pushes the stomach upwards. Most often, the symptoms worsen with physical activity, lying down, with frequent consumption of coffee or with smoking .

Stomach acid contains positively charged protons, while acid-binding agents such as almasyl have negatively charged components that neutralize the positive protons. The acid is thus balanced due to the basic reaction.

Medical Application & Use

Almasilat can bind harmful bile acids that might otherwise get from the intestine into the stomach. Furthermore, the active ingredient also has a mucous membrane-protecting effect. Together with the gastric acid, salts are formed that are difficult to dissolve and are excreted with the stool . They also reduce the risk of ulcers in the stomach or intestines due to acidosis.

Almamilat is available without a prescription. However, if the stomach problems last longer than 14 days, it is advisable to consult a doctor. If almasilat is taken over a longer period of time, the aluminum level should also be checked regularly. Almasilat is used for acid-related diseases such as stomach and duodenal ulcers and heartburn. Up to four times 1000 milligrams of the drug should be taken daily after meals or before going to bed. Children and adolescents under the age of 12 should not take the medicine as there is little experience in this age group.

Risks & side effects

When taking almasilat, the following side effects may occur:

Almasilat should not be taken if you are hypersensitive to the minerals magnesium and aluminum or if you are allergic to the active ingredient. In addition, it is not advisable to take it if you have reduced phosphate levels, colon obstruction or constipation.

In principle, almasyl can be used during pregnancy , but only low doses should be taken over a short period of time in order to protect the unborn child from excessive aluminum exposure. Small amounts of aluminum compounds can also pass into breast milk , but the risk for the child is not too great. Due to a lack of studies, the drug should only be used for a short time during breastfeeding .

It should also be noted that almasyl reduces the absorption of certain antibiotics and cardiac glycosides , and it also impairs the absorption of holofantine (malaria drug), anticoagulant drugs , cardiac beta- blockers , various ions such as phosphate , fluoride and iron , ronitidine, cimetidine and chenodeoxycholic acid.

The intake of aluminum increases if almasyl is taken together with effervescent tablets and fruit juices. Furthermore, the pH value of the urine is increased due to the intake of almasyl. Caution is also required in patients with renal insufficiency , since chronic use can lead to accumulations of magnesium or aluminum hydroxide .
