Trade names of drugs with the active substance omeprazole

In Russia and other countries - former republics of the USSR, omeprazole is widely available in generic versions.
Prices for generic omeprazole are much lower than prices for original drugs, such as Losek, Losek MAPS, which is important for many patients and often determines the choice of drug. Due to possible differences in the quality of drugs, an objective assessment of their clinical effectiveness is often necessary. Currently, 24-hour monitoring of intragastric acidity is an objective and accessible method for testing antisecretory agents in clinical practice (Alekseenko S.A.). The following drugs are (were) registered in Russia: Bioprazole, Vero-Omeprazole, Gastrozol, Demeprazole, Zhelkizol, Zerotsid, Zolser, Chrismel, Lomak, Losek, Losek MAPS, Omegast, Omez, Omez Insta, Omecaps, Omepar, Omeprazole, Omeprazole pellets . , Pepticum, Pleom-20, Promez, Risek, Romesek, Sopral, Ulzol, Ulkozol, Ultop, Helitsid, Helol, Cisagast.

On the pharmaceutical markets of the countries of the former republics of the USSR, a number of drugs with the active substance omeprazole are presented, which are not registered in Russia, in particular: Gasek (Mepha Lda, Switzerland), Losid (Flamingo Pharmaceutical, India), Omeprazole-Astrapharm (TOV Astrapharm, Ukraine ), Omeprazole-Darnitsa (JSC Pharmaceutical Company Darnitsa, Ukraine), Omeprazole-KMP (JSC Kievmedpreparat, Ukraine), Omeprazole-Lugal (Lugansk Chemical Pharmaceutical Plant, Ukraine), Tserol (Neon Antibiotics Private Limited, India) and others.

Indications

Peptic ulcer of the stomach and duodenum in the acute phase (including those associated with Helicobacter pylori), reflux esophagitis, Zollinger-Ellison syndrome, erosive and ulcerative lesions of the stomach and duodenum associated with taking NSAIDs.

Contraindications for use

Chronic liver diseases (including a history), childhood, hypersensitivity to omeprazole.

pharmachologic effect

H+-K+-ATPase inhibitor. It inhibits the activity of H+-K+-ATPase in the parietal cells of the stomach and thereby blocks the final stage of hydrochloric acid secretion. This leads to a decrease in the level of basal and stimulated secretion, regardless of the nature of the stimulus. Due to a decrease in acid secretion, it reduces or normalizes the effect of acid on the esophagus in patients with reflux esophagitis.

Omeprazole has a bactericidal effect on Helicobacter pylori. Eradication of H. pylori with the simultaneous use of omeprazole and antibiotics allows you to quickly relieve the symptoms of the disease, achieve a high degree of healing of damaged mucosa and stable long-term remission and reduce the likelihood of bleeding from the gastrointestinal tract.

Drug interactions

With simultaneous use, cases of the development of symptoms of the toxic effects of benzodiazepines have been described, which is associated with inhibition of the activity of CYP3A isoenzymes and, apparently, CYP2C9.

When used simultaneously with atracurium besylate, the effects of atracurium besylate are prolonged.

When used concomitantly with bismuth tripotassium dicitrate, an undesirable increase in the absorption of bismuth may occur.

When used simultaneously with digoxin, a slight increase in the concentration of omeprazole in the blood plasma is possible.

When used simultaneously with disulfiram, a case of impaired consciousness and catatonia has been described; with indinavir - a decrease in the concentration of indinavir in the blood plasma is possible; with ketoconazole - decreased absorption of ketoconazole.

With prolonged simultaneous use with clarithromycin, the concentrations of omeprazole and clarithromycin in the blood plasma increase.

Cases of decreased excretion of methotrexate from the body in patients receiving omeprazole have been described.

When used simultaneously with theophylline, a slight increase in the clearance of theophylline is possible.

It is believed that with the simultaneous use of omeprazole in high doses and phenytoin, an increase in the concentration of phenytoin in the blood plasma is possible.

Cases of increased concentrations of cyclosporine in blood plasma have been described when used simultaneously with cyclosporine.

When used simultaneously with erythromycin, a case of increased concentration of omeprazole in the blood plasma was described, while the effectiveness of omeprazole decreased.

Pharmacokinetics

Suction.
Omeprazole is rapidly absorbed from the gastrointestinal tract, the maximum concentration in plasma is reached after 1-2 hours. Absorbed in the small intestine, usually within 3-6 hours. Bioavailability after a single oral dose is approximately 40%; after continuous once-daily dosing, bioavailability increases to 60%. Concomitant food intake does not affect the bioavailability of omeprazole. Distribution. The binding of omeprazole to plasma proteins is about 95%, the volume of distribution is 0.3 l/kg.

Metabolism. Omeprazole is completely metabolized in the liver. The main isoenzymes involved in the metabolic process are CYP2C19 and CYP3A4. Hydroxyomeprazole is the main metabolite formed under the action of the CYP2C19 isoenzyme. Metabolites sulfone and sulfide do not affect the secretion of hydrochloric acid.

Excretion. The half-life is approximately 40 minutes (30-90 minutes). About 80% is excreted in the form of metabolites by the kidneys, the rest through the intestines.

Special groups of patients. In elderly patients (75-79 years old), a slight decrease in the metabolism of omeprazole was noted.

In patients with impaired renal function, no dose adjustment is required. The metabolism of omeprazole in patients with impaired liver function slows down, which leads to an increase in its bioavailability.

When treating children aged 1 year, plasma concentrations of omeprazole were similar to those in adults.

special instructions

Before starting therapy, it is necessary to exclude the presence of a malignant process in the upper gastrointestinal tract.
because Taking Omeprazole-Teva may mask symptoms and delay the correct diagnosis. Reducing gastric acidity, including when using proton pump blockers, increases the number of bacteria in the gastrointestinal tract, which increases the risk of gastrointestinal infections. Due to decreased secretion of hydrochloric acid, the concentration of chromogranin A (CgA) increases. Increased concentrations of CgA may affect the results of examinations for the detection of neuroendocrine tumors. To prevent this effect, it is necessary to temporarily stop taking omeprazole 5 days before the CgA concentration test. In patients with severe liver dysfunction, it is necessary to regularly monitor liver enzymes during therapy with Omeprazole-Teva.

The drug Omeprazole-Teva contains sucrose and is therefore contraindicated in patients with congenital disorders of carbohydrate metabolism (fructose intolerance, sucrase/isomaltase deficiency, glucose-galactose malabsorption).

When treating erosive and ulcerative lesions associated with NSAID use, the possibility of limiting or discontinuing NSAID use should be carefully considered to increase the effectiveness of antiulcer therapy.

The drug contains sodium, which should be taken into account in patients on a controlled sodium diet.

The risk-benefit ratio of long-term (more than 1 year) maintenance therapy with Omeprazole-Teva should be regularly assessed. There is evidence of an increased risk of fractures of the vertebrae, wrist bones, and head of the femur, mainly in elderly patients, as well as in the presence of predisposing factors. Patients at risk of developing osteoporosis should ensure adequate intake of vitamin D and calcium.

There are reports of the occurrence of severe hypomagnesemia in patients receiving therapy with proton pump inhibitors, including omeprazole, for more than 1 year.

Patients receiving omeprazole therapy for a long time, especially in combination with digoxin or other drugs that reduce the level of magnesium in the blood plasma (diuretics), require regular monitoring of magnesium levels.

Omeprazole, like all drugs that reduce acidity, can lead to decreased absorption of vitamin B12 (cyanocobalamin). This must be remembered in patients with a reduced supply of vitamin B12 in the body or with risk factors for impaired absorption of vitamin B12 during long-term therapy.

Patients who took drugs orally for a long time that reduce the secretion of gastric glands were more likely to develop glandular cysts in the stomach. These phenomena are caused by physiological changes as a result of inhibition of hydrochloric acid secretion, and undergo reverse development as therapy continues.

A decrease in the secretion of hydrochloric acid in the stomach leads to an increase in the growth of normal intestinal microflora, which, in turn, can lead to a slight increase in the risk of developing intestinal infections caused by bacteria of the genus Salmonella spp. and Campylobacter spp., as well as probably Clostridium difficile.

Description

Gastric gland secretion-lowering agent - proton pump inhibitor.

Pharmacodynamics

Omeprazole is a racemic mixture of two enantiomers that reduces the secretion of hydrochloric acid due to specific inhibition of the proton pump of gastric parietal cells. With a single use, it acts quickly and has a reversible inhibition of hydrochloric acid secretion.

Mechanism of action

Omeprazole is a weak base, it becomes active in the acidic environment of the tubules of the cells of the parietal layer of the gastric mucosa, where it is activated and inhibits the H+/K+-ATPase of the proton pump. It has a dose-dependent effect on the last stage of hydrochloric acid synthesis, inhibits both basal and stimulated secretion, regardless of the stimulating factor.

Effect on the secretion of hydrochloric acid in the stomach

After oral administration of omeprazole once a day, there is a rapid and effective decrease in daytime and nighttime secretion of hydrochloric acid, which reaches a maximum within 4 days of treatment.

In patients with duodenal ulcer, 20 mg omeprazole causes a sustained reduction in 24-hour gastric acidity by at least 80%. In this case, a 70% decrease in the average maximum concentration of hydrochloric acid after stimulation with pentagastrin is achieved within 24 hours. Daily oral administration of 20 mg omeprazole in patients with duodenal ulcer maintains pH >3 for an average of 17 hours.

The degree of inhibition of hydrochloric acid secretion is proportional to the area under the tinnitus curve (usually disappears after cessation of therapy).

From the gastrointestinal tract: often - nausea, vomiting, flatulence, constipation, diarrhea, abdominal pain (in most cases, the severity of these phenomena increases with continued therapy), glandular polyps of the fundus of the stomach (benign); rarely - loss of taste, change in color of the tongue to brown-black and the appearance of benign cysts of the salivary glands when used simultaneously with clarithromycin (the phenomena are reversible after cessation of therapy), microscopic colitis; very rarely - dry mouth, stomatitis, candidiasis, pancreatitis.

From the liver and biliary tract: infrequently - changes in the activity of liver enzymes (reversible); very rarely - hepatitis, jaundice, liver failure, encephalopathy in patients with underlying liver diseases.

Use during pregnancy and breastfeeding

Research results indicate no adverse effects on the course of pregnancy, the health of the fetus and newborn child.
Omeprazole can be used with caution during pregnancy. Omeprazole is excreted in breast milk. However, when used in therapeutic doses, the effect on a child is unlikely.

Interaction

Active substances with pH-dependent absorption
A decrease in gastric acidity when using omeprazole can increase or decrease the absorption of pharmacologically active substances.

Nelfinavir, atazanavir

When used concomitantly with omeprazole, a significant decrease in plasma concentrations of atazanavir and nelfinavir may be observed.

The simultaneous use of omeprazole and nelfinavir is contraindicated. Concomitant use of omeprazole (40 mg daily) reduces nelfinavir exposure by approximately 40% and mean exposure to the pharmacologically active metabolite M8 is reduced by 75-90%. The interaction may involve a mechanism of CYP1C19 inhibition. Concomitant use of omeprazole with atazanavir is not recommended.

Coadministration of omeprazole (40 mg daily) and atazanavir 300 mg/ritonavir 100 mg in healthy volunteers resulted in a 75% reduction in atazanavir exposure. Increasing the atazanavir dose to 400 mg does not compensate for the effect of omeprazole on atazanavir exposure. Administration of 20 mg omeprazole per day with 400 mg atazanavir and 100 mg ritonavir to healthy volunteers resulted in an approximately 30% reduction in atazanavir exposure and was comparable to exposure with a single dose of 300 mg atazanavir and 100 mg ritonavir.

Digoxin

Concomitant treatment with omeprazole (20 mg daily) and digoxin in healthy volunteers increased the bioavailability of digoxin by 10%. Although glycoside toxicity with omeprazole is not a common event, increased monitoring is necessary, especially when treating elderly patients.

Clopidogrel

In a crossover clinical study, the duration of taking clopidogrel in combination with clopidogrel and omeprazole at a dose of 80 mg was 5 days. Exposure to the active metabolite of clopidogrel was reduced by 46% (on day 1) and 42% (on day 5) when clopidogrel and omeprazole were co-administered. The mean time to platelet aggregation inhibition was reduced by 47% (24 hours) and 30% (day 5) when clopidogrel and omeprazole were co-administered. Another study showed that taking clopidogrel and omeprazole at different times did not prevent their interaction, which is likely due to the inhibitory effect of omeprazole on CYP2C19. Observational and clinical studies have provided conflicting data on the clinical impact of these PK/PD interactions on the development of severe cardiovascular events.

Other medicines

The absorption of posaconazole, erlotinib, ketaconazole and itraconazole is significantly reduced, and their clinical effectiveness is accordingly impaired. Avoid co-administration of omeprazole with posaconazole or erlotinib.

Medicines metabolized by the CYP2C19 isoenzyme

Omeprazole moderately inhibits CYP2C19, the main enzyme in the metabolism of omeprazole. Therefore, the metabolism of other drugs also metabolized by CYP2C19 may be reduced and their systemic exposure increased. Examples of such drugs are R-warfarin and other vitamin K antagonists, cilostazol, diazepam and phenytoin.

Cilostazol

In a crossover clinical study, administration of omeprazole 40 mg to healthy volunteers increased the Cmax and AUC of cilostazol by 18% and 26%, respectively, and one of the active metabolites of cilostazol by 29% and 69%, respectively.

Phenytoin

Monitoring plasma concentrations of phenytoin is recommended during the first two weeks after initiation of omeprazole therapy and in case of dose adjustment of phenytoin; Monitoring and subsequent dose adjustment of phenytoin should be carried out until the end of treatment with omeprazole.

Unknown mechanism of interaction

Saquinavir

Coadministration of omeprazole and saquinavir/ritonavir is well tolerated in HIV-infected patients and also results in a reduction in plasma concentrations of saquinavir by approximately 70%.

Tacrolimus

Coadministration with omeprazole reduces the serum concentration of tacrolimus. Increased monitoring of tacrolimus concentrations and renal function (creatinine clearance) should be carried out, with tacrolimus dose adjustments if necessary.

The influence of other drugs on the pharmacokinetics of omeprazole

Inhibitors of the isoenzyme CYP2C19 and/or CYP3A4 Given the metabolism of omeprazole with the participation of the isoenzymes CYP2C19 and CYP3A4, drugs that can inhibit these enzymes (such as clarithromycin and voriconazole) may reduce the serum concentration of omeprazole, increasing the rate of its metabolism.

No effect on metabolism

Omeprazole does not affect the metabolism of drugs metabolized by the CYP3A4 isoenzyme, such as cyclosporine, lidocaine, quinidine, estradiol, erythromycin and budesonide.

No interaction of omeprazole with the following drugs has been identified: antacids, caffeine, theophylline, S-warfarin, piroxicam, diclofenac, naproxen, metoprolol, propranolol and ethanol.

Overdose

Symptoms: vomiting, abdominal pain, diarrhea, dizziness, depression, blurred vision, drowsiness, agitation, confusion, headache, increased sweating, dry mouth, nausea, arrhythmia.

Treatment: symptomatic therapy, hemodialysis is not effective enough. A specific antidote is not known.

Impact on the ability to drive vehicles and operate machinery

Considering the possibility of undesirable effects on the central nervous system and the organ of vision, during treatment with omeprazole, care must be taken when driving vehicles and engaging in potentially hazardous activities that require increased concentration and speed of psychomotor reactions.
