Pharmacological effect

The antiulcer drug leads to the direct death of microorganisms, i.e. has a bactericidal effect on the bacteria Helicobacter pylori. De-nol is also characterized by astringent and anti-inflammatory effect. In the acidic gastric contents, insoluble compounds of bismuth citrate and oxychloride are deposited on the mucous membrane. On the surface of erosive and ulcerative lesions a protective film is formed in the form of chelate compounds with protein molecules.

The intake of De-nola leads to the stimulation of the activity of the cell-protecting mechanisms and the enhancement of the resistance of the gastric mucosa to the negative effects of hydrochloric acid, the proteolytic enzyme pepsin, as well as enzymes and bile salts. These effects are due to the activation of the synthesis of prostaglandin E, bicarbonate and mucus.

We picked up some reviews of people about the drug De-Nol:

  1. Liza. Most importantly, it helps. Twice I had exacerbation of erosive gastritis, each time in the appointment was de-nol and phosphalugel in combination with a diet. The pains passed in a week, and in a month I already completely forgot about the problem.
  2. Yevgen. After the examination, I was diagnosed with a gastric ulcer, and a helicobacter bacterium was identified. The doctor prescribed a comprehensive treatment, it included antibiotics, Trichopol and the drug De-Nol. In the process of treatment, nausea, metallic taste in the mouth appeared, but the doctor said that this was normal and would be better in a few days. Indeed, after a week I already felt fine, but the stool was colored black. It turns out that this is a reaction to the active substance De-Nola-bismuth salt. So do not be afraid. As a result, after the course of treatment, the control probing showed that the erosion is well tightened, and in the analyzes the pathogen is absent. Now the general state of health is excellent, I hope there will be no recurrence of the disease.
  3. Sergei. To all lovers of de nol: if you have an itch and a rash after the second or third intake, immediately drop it! This is not an allergy, it is bismuth poisoning - for some people it is absorbed into the blood through the stomach for some reason, why scientists don’t know it, but they are modestly silent about it in the annotation to the drug. and the defeat of the internal organs is unknown to us.
  4. Anna. De-nol contains bismuth, which paints the stool in a characteristic black color. I was frightened at first, because somewhere in my memory it was postponed from the wilds of the Internet that a dramatic darkening of the chair without a change in diet could be a sign of gastric bleeding.
