DRUGS & SUPPLEMENTS
How often in a day do you take medicine? How many times?
Omepraz is an inhibitor of H+ K+ ATPase. This medication inhibits the activity of H+-K+-ATPase in gastric parietal cells and thus blocks the final stage of hydrochloric acid secretion. This leads to a reduction in basal and stimulated secretion, regardless of the nature of the stimulus. Due to the reduction of acid secretion Omepraz reduces or normalizes the effects of acid in the esophagus in patients with reflux esophagitis.
Omepraz has a bactericidal effect on Helicobacter pylori. Eradication of H. pylori when Omepraz used with antibiotics allows to quickly arrest the symptoms, to take a high degree of healing of damaged mucosa and persistent long-term remission and reduce the likelihood of bleeding from the gastrointestinal tract.
After oral administration Omepraz is rapidly absorbed from the gastrointestinal tract. This drug penetrates the parietal cells of gastric mucosa. Plasma protein binding is about 95%. Omepraz is biotransformed in the liver. Excreted by the kidneys - 72-80%, in the faeces - about 20%. T1/2 is 0.5-1 h. In patients with chronic liver diseases T1/2 increases up to 3 hours.
Gastric ulcer and duodenal ulcer in acute phase (including associated with Helicobacter pylori), reflux esophagitis, Zollinger-Ellison syndrome, erosive and ulcerative lesions of gastric and duodenal ulcers associated with taking NSAIDs.
The dosing regimen of Omepraz is individual. When this medication is administered orally of the single dose is 20-40 mg. The daily dose is 20-80 mg, the frequency of use is 1-2 times / day. The duration of treatment is 2-8 weeks.

Category effects on the fetus by FDA - C.
Before the treatment with Omepraz it is necessary to exclude the possibility of a malignant process because Omepraz treatment can mask symptoms and delay the correct diagnosis.
Therapy with Omepraz may affects results of laboratory studies of liver and gastrin concentrations in blood plasma.
Due to lack of experience in clinical application of Omepraz this medicine is not recommended for children.
This medication alters the bioavailability of any drug, absorption depends on pH (ketoconazole, iron salts, etc.). Omepraz slows down the elimination of drugs metabolized in the liver by microsomal oxidation (warfarin, diazepam, phenytoin, etc.).
Omepraz enhances the action of coumarin and diphenine, does not change - NSAIDs. This drug increases (relative) the concentration of clarithromycin in the blood; may increases the leukopenic and thrombocytopenic effects of depressants hematopoiesis drugs. Substance for intravenous infusion is compatible only with saline and dextrose (using other solvents may decrease the stability of Omepraz due to changes in pH of infusion medium).
Symptoms: dry mouth, nausea, blurred vision, headache, increased sweating, flushing, tachycardia, drowsiness, confusion.
Treatment: symptomatic, dialysis is ineffective.
