Pharmacological action
Pharmacodynamics
The combination of two active substances (domperidone and omeprazole) has a complex effect on the main pathogenesis of gastroesophageal reflux disease (GERD), dyspeptic disorders of various origins. Domperidone enhances and synchronizes physiological peristaltic waves, omeprazole reduces basal and stimulated secretion of hydrochloric acid.
Omeprazole
Mechanism of Action
Omeprazole is concentrated in the acidic environment of the secretory tubules of the parietal cells of the gastric mucosa, and the proton pump is activated and inhibits the enzyme H + / K + ATPase, which provides a dose-dependent highly effective inhibition of basal and stimulated secretion of hydrochloric acid, regardless of the stimulating factor.
Effect on gastric acidity
The maximum effect is achieved within 4 days of treatment. In patients with a duodenal ulcer, omeprazole at a dose of 20 mg causes a steady decrease of 24 hourly gastric acidity of not less than 80%. This achieves a decrease in the average maximum concentration of hydrochloric acid after stimulation with pentagastrin by 70% within 24 hours. In patients with duodenal ulcer, omeprazole 20 mg, with daily oral administration, maintains an intragastric pH value of pH 3 for an average of 17 hours a day. Inhibition of hydrochloric acid secretion depends on the area under the pharmacokinetic curve "concentration - time" (AUC) of omeprazole, and not on the concentration of the drug in plasma at a given time.
Effects on Helicobacter pylori
Eradication of Helicobacter pylori with omeprazole in combination with antibacterial agents is accompanied by a rapid elimination of symptoms, a high degree of healing of gastric mucosa defects intestinal tract and prolonged remission of peptic ulcer, which reduces the likelihood of complications such as bleeding, as effective as continuous maintenance therapy.
Other effects of
A decrease in the secretion of hydrochloric acid in the stomach leads to a slight increase in the risk of intestinal infections caused by Salmonella spp., Campylobacter spp. and Clostridium difficile. During treatment with drugs that lower the secretion of the glands of the stomach, the concentration of gastrin in the blood serum rises. Due to a decrease in the secretion of hydrochloric acid, the concentration of chromogranin A increases (see section "Special instructions").
Domperidone
A dopamine antagonist that combines peripheral (gastrokinetic) action and antagonism to dopamine receptors in the trigger zone of the brain (central effect), due to which it has an antiemetic effect, stimulates the release of prolactin from the pituitary gland and eliminates the inhibitory effect of dopamine on gastrointestinal function intestinal tract, enhances and synchronizes peristaltic waves, thereby accelerating the natural emptying of the stomach and increases the pressure of the sphincter of the lower esophagus.

Drug Interactions
Omeprazole
A potential metabolic interaction between omeprazole and other drugs is highly unlikely. However, since omeprazole delays the hepatic microsomal metabolism of drugs (cytochrome P450 enzyme system), the elimination of other drugs that require hepatitis metabolism via the cytochrome P450 enzyme system, or which is highly extracted for the liver, can be reduced during the concomitant use of omeprazole. Such an effect may be a consequence of further delayed withdrawal of the drug, an increase in the concentration of diazepam, diphenin and anticoagulants in the blood concentration, such as warfarin (control of blood concentration or prothrombin time, which is recommended in the further choice of dosage, after the initial dosage necessary during the entire period of treatment with omeprazole is determined).
Omeprazole, by increasing the pH level in the stomach, can subsequently affect the bioaccumulation of any drugs for which the absorption is pH-dependent, and omeprazole can prevent a decrease in the effect of acid-changing drugs on the body. Therefore, the concomitant use of itraconazole and ketoconazole together with omeprazole can lead to a decrease in the absorption level of these drugs.
Omeprazole does not affect any other significantly important CYP isoforms, resulting in a loss of metabolic interaction with the main substances for the formation of CYP1A2 (caffeine, phenacetin, aminophylline), CYP2C9 (S-warfarin), CYP2D6 (metoprolol, propranolol), CYP2E1, (ethanol) and CYP3A (cyclosporine, iodocaine, quinidine, estradiol, erythromycin).
No strong effect of omeprazole on the steady state pharmacokinetics of piroxicam, diclofenac and naproxen was observed during the study of healthy patients in the process of receiving repeated doses of omeprazole 20 mg.
Domperidone
Positive effects of domperidone may be associated with concomitant cholinergic drugs.
Since domperidone is used as a drug prescribed to improve the low motility of the gastrointestinal tract, the absorption of this drug can be accelerated in the small intestine, while the absorption of this drug through the stomach is very slow.
Caution is advised when combining domperidone with monoamine oxidase inhibitors.
The absorption of domperidone was not reduced when taken in combination with antacids or drugs that block H2 receptors.
The main role in domperidone metabolism is played by the CYP3A4 isoenzyme. The results of in vitro studies and clinical experience show that the simultaneous use of drugs that significantly inhibit this isoenzyme can cause an increase in plasma concentrations of domperidone. Potential CYP3A4 inhibitors include:
• Azole antifungals such as fluconazole *, itraconazole, ketoconazole * and voriconazole *
• Macrolide antibiotics, such as clarithromycin * and erythromycin * HIV, antiviral antiviral agents, for example, antiviral inhibitors , indinavir, nelfinavir, ritonavir and sahinavir
• Calcium antagonists such as diltiazem and verapamil
• Amiodarone *
• Aprepitant
• Nefazodon.
• Telithromycin *
(Drugs marked with an asterisk also extend the QT interval (see section "Contraindications").

Pharmacodynamics
The combination of two active substances (domperidone and omeprazole) has a complex effect on the main pathogenesis of gastroesophageal reflux disease (GERD), dyspeptic disorders of various origins. Domperidone enhances and synchronizes physiological peristaltic waves, omeprazole reduces basal and stimulated secretion of hydrochloric acid.
Omeprazole
Mechanism of Action
Omeprazole is concentrated in the acidic environment of the secretory tubules of the parietal cells of the gastric mucosa, and the proton pump is activated and inhibits the enzyme H + / K + ATPase, which provides a dose-dependent highly effective inhibition of basal and stimulated secretion of hydrochloric acid, regardless of the stimulating factor.
Effect on gastric acidity
The maximum effect is achieved within 4 days of treatment. In patients with a duodenal ulcer, omeprazole at a dose of 20 mg causes a steady decrease of 24 hourly gastric acidity of not less than 80%. This achieves a decrease in the average maximum concentration of hydrochloric acid after stimulation with pentagastrin by 70% within 24 hours. In patients with duodenal ulcer, omeprazole 20 mg, with daily oral administration, maintains an intragastric pH value of pH 3 for an average of 17 hours a day. Inhibition of hydrochloric acid secretion depends on the area under the pharmacokinetic curve "concentration - time" (AUC) of omeprazole, and not on the concentration of the drug in plasma at a given time.
Effects on Helicobacter pylori
Eradication of Helicobacter pylori with omeprazole in combination with antibacterial agents is accompanied by a rapid elimination of symptoms, a high degree of healing of gastric mucosa defects intestinal tract and prolonged remission of peptic ulcer, which reduces the likelihood of complications such as bleeding, as effective as continuous maintenance therapy.
Other effects of
A decrease in the secretion of hydrochloric acid in the stomach leads to a slight increase in the risk of intestinal infections caused by Salmonella spp., Campylobacter spp. and Clostridium difficile. During treatment with drugs that lower the secretion of the glands of the stomach, the concentration of gastrin in the blood serum rises. Due to a decrease in the secretion of hydrochloric acid, the concentration of chromogranin A increases (see section "Special instructions").
Domperidone
A dopamine antagonist that combines peripheral (gastrokinetic) action and antagonism to dopamine receptors in the trigger zone of the brain (central effect), due to which it has an antiemetic effect, stimulates the release of prolactin from the pituitary gland and eliminates the inhibitory effect of dopamine on gastrointestinal function intestinal tract, enhances and synchronizes peristaltic waves, thereby accelerating the natural emptying of the stomach and increases the pressure of the sphincter of the lower esophagus.

Special instructions
Lactose
Omeprazole granules contain lactose, so do not use OmezВ® DSR in patients with lactose intolerance, galactosemia and glucose and galactose malabsorption.
Cardiovascular system
It has been shown that the use of domperidone may be associated with an increased risk of ventricular arrhythmias or sudden coronary death, which is more likely for patients over 60 with a daily dose of domperidone greater than 30 mg. The use of domperidone and other drugs, leading to lengthening of the QT interval requires caution in patients with existing conduction disturbances with QT lengthening, severe electrolyte imbalance or congestive heart failure).
Osteoporosis
Patients at risk of developing osteoporosis or fractures in the background should be under appropriate clinical supervision, although a causal relationship with the use of omeprazole with fractures in the setting of osteoporosis has not been established.

Drug Interactions
Omeprazole
A potential metabolic interaction between omeprazole and other drugs is highly unlikely. However, since omeprazole delays the hepatic microsomal metabolism of drugs (cytochrome P450 enzyme system), the elimination of other drugs that require hepatitis metabolism via the cytochrome P450 enzyme system, or which is highly extracted for the liver, can be reduced during the concomitant use of omeprazole. Such an effect may be a consequence of further delayed withdrawal of the drug, an increase in the concentration of diazepam, diphenin and anticoagulants in the blood concentration, such as warfarin (control of blood concentration or prothrombin time, which is recommended in the further choice of dosage, after the initial dosage necessary during the entire period of treatment with omeprazole is determined).
Omeprazole, by increasing the pH level in the stomach, can subsequently affect the bioaccumulation of any drugs for which the absorption is pH-dependent, and omeprazole can prevent a decrease in the effect of acid-changing drugs on the body. Therefore, the concomitant use of itraconazole and ketoconazole together with omeprazole can lead to a decrease in the absorption level of these drugs.
Omeprazole does not affect any other significantly important CYP isoforms, resulting in a loss of metabolic interaction with the main substances for the formation of CYP1A2 (caffeine, phenacetin, aminophylline), CYP2C9 (S-warfarin), CYP2D6 (metoprolol, propranolol), CYP2E1, (ethanol) and CYP3A (cyclosporine, iodocaine, quinidine, estradiol, erythromycin).
No strong effect of omeprazole on the steady state pharmacokinetics of piroxicam, diclofenac and naproxen was observed during the study of healthy patients in the process of receiving repeated doses of omeprazole 20 mg.
Domperidone
Positive effects of domperidone may be associated with concomitant cholinergic drugs.
Since domperidone is used as a drug prescribed to improve the low motility of the gastrointestinal tract, the absorption of this drug can be accelerated in the small intestine, while the absorption of this drug through the stomach is very slow.
Caution is advised when combining domperidone with monoamine oxidase inhibitors.
The absorption of domperidone was not reduced when taken in combination with antacids or drugs that block H2 receptors.
The main role in domperidone metabolism is played by the CYP3A4 isoenzyme. The results of in vitro studies and clinical experience show that the simultaneous use of drugs that significantly inhibit this isoenzyme can cause an increase in plasma concentrations of domperidone. Potential CYP3A4 inhibitors include:
• Azole antifungals such as fluconazole *, itraconazole, ketoconazole * and voriconazole *
• Macrolide antibiotics, such as clarithromycin * and erythromycin * HIV, antiviral antiviral agents, for example, antiviral inhibitors , indinavir, nelfinavir, ritonavir and sahinavir
• Calcium antagonists such as diltiazem and verapamil
• Amiodarone *
• Aprepitant
• Nefazodon.
• Telithromycin *
(Drugs marked with an asterisk also extend the QT interval (see section "Contraindications").
