Medicinal effects on the body

Due to its ability to block histamine receptors, the drug suppresses the release of hydrochloric acid. It affects both its own pathological production of excess acid and secretion stimulated by various substances. This could be acetylcholine, histamine, gastrin, caffeine.

By reducing the secretion of hydrochloric acid, it reduces the acidity of gastric juice and the activity of enzymes that break down peptide compounds in the digestive tract. Thanks to this, antiulcer and analgesic effects are achieved, the functioning of the digestive tract is improved and the load on the pancreas is reduced.

Absorbed quickly when administered orally, binds to blood proteins. Penetrates into the tissues of the pancreas, liver, kidneys and gastrointestinal tract. The half-life is up to two hours. Most of it is excreted in urine, and up to six percent is excreted in feces.
