⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Gastric Malignancy: In adults, symptomatic response does not preclude the presence of gastric malignancy. Consider additional follow-up and diagnostic testing. (5.1) Acute Tubulointerstitial Nephritis: Discontinue treatment and evaluate patients.
(5.2) Sodium Bicarbonate Buffer Content: Take sodium content into consideration in patients on a sodium-restricted diet. Avoid in patients with Bartter’s syndrome, hypokalemia, hypocalcemia, and problems with acid-base balance. (5.3) Clostridium difficile-Associated Diarrhea: PPI therapy may be associated with increased risk.
(5.4) Bone Fracture: Long-term and multiple daily dose PPI therapy may be associated with an increased risk for osteoporosis-related fractures of the hip, wrist, or spine. (5.5) Severe Cutaneous Adverse Reactions: Discontinue at the first signs or symptoms of severe cutaneous adverse reactions or other signs of hypersensitivity and consider further evaluation. (5.6) Cutaneous and Systemic Lupus Erythematosus: Mostly cutaneous; new onset or exacerbation of existing disease; discontinue omeprazole and sodium bicarbonate and refer to specialist for evaluation.
(5.7) Interaction with Clopidogrel: Avoid concomitant use of omeprazole and sodium bicarbonate. (5.8) Cyanocobalamin (Vitamin B-12) Deficiency: Daily long-term use (e.g., longer than 3 years) may lead to malabsorption or a deficiency of cyanocobalamin. (5.9) Hypomagnesemia and Mineral Metabolism: Reported rarely with prolonged treatment with PPIs.
(5.10) Interaction with St. John’s wort or Rifampin: Avoid concomitant use of omeprazole and sodium bicarbonate. (5.11, 7) Interactions with Diagnostic Investigations for Neuroendocrine Tumors: Increased Chromogranin A (CgA) levels may interfere with diagnostic investigations for neuroendocrine tumors; temporarily stop omeprazole and sodium bicarbonate at least 14 days before assessing CgA levels.
(5.12) Interaction with Methotrexate: Concomitant use with PPIs may elevate and/or prolong serum concentrations of methotrexate and/or its metabolite, possibly leading to toxicity. With high dose methotrexate administration, consider a temporary withdrawal of omeprazole and sodium bicarbonate. (5.13, 7) Fundic Gland Polyps: Risk increases with long-term use, especially beyond one year.
Use the shortest duration of therapy. (5.14)
5.1Presence of Gastric Malignancy In adults, symptomatic response to therapy with omeprazole and sodium bicarbonate does not preclude the presence of gastric malignancy. Consider additional follow-up and diagnostic testing in adult patients who have a suboptimal response or an early symptomatic relapse after completing treatment with a proton pump inhibitor (PPI). In older patients, also consider an endoscopy.
5.2Acute Tubulointerstitial Nephritis Acute tubulointerstitial nephritis (TIN) has been observed in patients taking PPIs and may occur at any point during PPI therapy. Patients may present with varying signs and symptoms from symptomatic hypersensitivity reactions to non-specific symptoms of decreased renal function (e.g., malaise, nausea and anorexia). In reported case series, some patients were diagnosed on biopsy and in the absence of extra-renal manifestations (e.g., fever, rash or arthralgia).
Discontinue omeprazole and sodium bicarbonate and evaluate patients with suspected acute TIN [see Contraindications (4)] .
5.3Sodium Bicarbonate Buffer Content Each 20 mg and 40 mg packet of omeprazole and sodium bicarbonate for oral suspension contains 1,680 mg (20 mEq) of sodium bicarbonate. The total content of sodium in each packet is 460 mg. Chronic administration of bicarbonate with calcium or milk can cause milk-alkali syndrome.
Chronic use of sodium bicarbonate may lead to systemic alkalosis, and increased sodium intake can produce edema and weight gain. The sodium content of omeprazole and sodium bicarbonate products should be taken into consideration when administering to patients on a sodium-restricted diet…

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Tables 6 and 7 include drugs with clinically important drug interactions and interaction with diagnostics when administered concomitantly with omeprazole and instructions for preventing or managing them. Consult the labeling of concomitantly used drugs to obtain further information about interactions with PPIs. Table 6: Clinically Relevant Interactions Affecting Drugs Co-Administered with Omeprazole and Interaction with Diagnostics Antiretrovirals Clinical Impact: The effect of PPIs on antiretroviral drugs is variable.
The clinical importance and the mechanisms behind these interactions are not always known. Decreased exposure of some antiretroviral drugs (e.g., rilpivirine, atazanavir and nelfinavir) when used concomitantly with omeprazole may reduce antiviral effect and promote the development of drug resistance [see Clinical Pharmacology (12.3)] . Increased exposure of other antiretroviral drugs (e.g., saquinavir) when used concomitantly with omeprazole may increase toxicity [see Clinical Pharmacology (12.3)] .
There are other antiretroviral drugs which do not result in clinically relevant interactions with omeprazole. Intervention: Rilpivirine-containing products : Concomitant use with omeprazole and sodium bicarbonate is contraindicated [see Contraindications (4) ]. Atazanavir : Avoid concomitant use with omeprazole and sodium bicarbonate.
See prescribing information for atazanavir for dosing information. Nelfinavir : Avoid concomitant use with omeprazole and sodium bicarbonate. See prescribing information for nelfinavir.
Saquinavir : See the prescribing information for saquinavir for monitoring of potential saquinavir-related toxicities. Other antiretrovirals : See prescribing information for specific antiretroviral drugs. Warfarin Clinical Impact: Increased INR and prothrombin time in patients receiving PPIs, including omeprazole, and warfarin concomitantly.
Increases in INR and prothrombin time may lead to abnormal bleeding and even death. Intervention: Monitor INR and prothrombin time and adjust the dose of warfarin, if needed, to maintain target INR range. Methotrexate Clinical Impact: Concomitant use of omeprazole with methotrexate (primarily at high dose) may elevate and prolong serum concentrations of methotrexate and/or its metabolite hydroxymethotrexate, possibly leading to methotrexate toxicities.
No formal drug interaction studies of high-dose methotrexate with PPIs have been conducted [see Warnings and Precautions (5.12)]. Intervention: A temporary withdrawal of omeprazole and sodium bicarbonate may be considered in some patients receiving high-dose methotrexate. CYP2C19 Substrates (e.g., clopidogrel, citalopram, cilostazol, phenytoin, diazepam) Clopidogrel Clinical Impact: Concomitant use of omeprazole 80 mg results in reduced plasma concentrations of the active metabolite of clopidogrel and a reduction in platelet inhibition [see Clinical Pharmacology (12.3)].
There are no adequate combination studies of a lower dose of omeprazole or a higher dose of clopidogrel in comparison with the approved dose of clopidogrel . Intervention: Avoid concomitant use with omeprazole and sodium bicarbonate. Consider use of alternative anti-platelet therapy [see Warnings and Precautions (5.7)].
Citalopram Clinical Impact: Increased exposure of citalopram leading to an increased risk of QT prolongation [see Clinical Pharmacology (12.3)] . Intervention: Limit the dose of citalopram to a maximum of 20 mg per day. See prescribing information for citalopram.
Cilostazol Clinical Impact: Increased exposure of one of the active metabolites of cilostazol (3,4-dihydrocilostazol) [see Clinical Pharmacology (12.3)]. Intervention: Reduce the dose of cilostazol to 50 mg twice daily. See prescribing information for cilostazol.
Phenytoin Clinical Impact: Potential for increased exposure of phenytoin. Intervention: Monitor phenytoin serum concentrations. Dose adjustment may be needed to maintain therapeutic drug concentra…

8.1Pregnancy Risk Summary There are no adequate and well-controlled studies with omeprazole and sodium bicarbonate in pregnant women. Omeprazole and sodium bicarbonate for oral suspension contains omeprazole and sodium bicarbonate. Omeprazole There are no adequate and well-controlled studies with omeprazole in pregnant women.
Available epidemiologic data fail to demonstrate an increased risk of major congenital malformations or other adverse pregnancy outcomes with first trimester omeprazole use. Reproduction studies in rats and rabbits resulted in dose-dependent embryo-lethality at omeprazole doses that were approximately 3.4 to 34 times an oral human dose of 40 mg (based on a body surface area for a 60 kg person). Teratogenicity was not observed in animal reproduction studies with administration of oral esomeprazole (an enantiomer of omeprazole) magnesium in rats and rabbits during organogenesis with doses about 68 times and 42 times, respectively, an oral human dose of 40 mg esomeprazole or 40 mg omeprazole (based on body surface area for a 60 kg person).
Changes in bone morphology were observed in offspring of rats dosed through most of pregnancy and lactation at doses equal to or greater than approximately 34 times an oral human dose of 40 mg esomeprazole or 40 mg omeprazole. When maternal administration was confined to gestation only, there were no effects on bone physeal morphology in the offspring at any age ( see Data ). Sodium Bicarbonate Available data with sodium bicarbonate use in pregnant women are insufficient to identify a drug associated risk of major birth defects or miscarriage.
Published animal studies report that sodium bicarbonate administered to rats, mice or rabbits during pregnancy did not cause adverse developmental effects in offspring. The estimated background risks of major birth defects and miscarriage for the indicated population are unknown. All pregnancies have a background risk of birth defect, loss or other adverse outcomes.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Human Data There are no adequate and well-controlled studies with omeprazole and sodium bicarbonate in pregnant women. Four published epidemiological studies compared the frequency of congenital abnormalities among infants born to women who used omeprazole during pregnancy with the frequency of abnormalities among infants of women exposed to H2-receptor antagonists or other controls.
A population-based retrospective cohort epidemiological study from the Swedish Medical Birth Register, covering approximately 99% of pregnancies, from 1995-99, reported on 955 infants (824 exposed during the first trimester with 39 of these exposed beyond first trimester, and 131 exposed after the first trimester) whose mothers used omeprazole during pregnancy. The number of infants exposed in utero to omeprazole that had any malformation, low birth weight, low Apgar score, or hospitalization was similar to the number observed in this population.
The number of infants born with ventricular septal defects and the number of stillborn infants was slightly higher in the omeprazole-exposed infants than the expected number in this population. A population-based retrospective cohort study covering all live births in Denmark from 1996-2009 reported on 1,800 live births whose mothers used omeprazole during the first trimester of pregnancy and 837,317 live births whose mothers did not use any PPI. The overall rate of birth defects in infants born to mothers with first trimester exposure to omeprazole was 2.9% and 2.6% in infants born to mothers not exposed to any PPI during the first trimester.

🧒 Pediatric Use ▾
8.4Pediatric Use Safety and effectiveness of omeprazole and sodium bicarbonate have not been established in pediatric patients. Juvenile Animal Data Esomeprazole, an enantiomer of omeprazole, was shown to decrease body weight, body weight gain, femur weight, femur length, and overall growth at oral doses about 34 to 68 times a daily human dose of 40 mg esomeprazole or 40 mg omeprazole based on body surface area in a juvenile rat toxicity study. The animal to human dose multiples are based on the assumption of equal systemic exposure to esomeprazole in humans following oral administration of either 40 mg esomeprazole or 40 mg omeprazole.
A 28-day toxicity study with a 14-day recovery phase was conducted in juvenile rats with esomeprazole magnesium at doses of 70 to 280 mg/kg/day (about 17 to 68 times a daily oral human dose of 40 mg esomeprazole or 40 mg omeprazole on a body surface area basis). An increase in the number of deaths at the high dose of 280 mg/kg/day was observed when juvenile rats were administered esomeprazole magnesium from postnatal day 7 through postnatal day 35. In addition, doses equal to or greater than 140 mg/kg/day (about 34 times a daily oral human dose of 40 mg esomeprazole or 40 mg omeprazole on a body surface area basis), produced treatment-related decreases in body weight (approximately 14%) and body weight gain, decreases in femur weight and femur length, and affected overall growth.
Comparable findings described above have also been observed in this study with another esomeprazole salt, esomeprazole strontium, at equimolar doses of esomeprazole.
🧓 Geriatric Use ▾
8.5Geriatric Use Omeprazole was administered to over 2,000 elderly individuals (≥65 years of age) in clinical trials in the U.S. and Europe. There were no differences in safety and effectiveness between the elderly and younger subjects. Other reported clinical experience has not identified differences in response between the elderly and younger subjects, but greater sensitivity of some older individuals cannot be ruled out.
Pharmacokinetic studies with buffered omeprazole have shown the elimination rate was somewhat decreased in the elderly and bioavailability was increased. The plasma clearance of omeprazole was 250 mL/min (about half that of young subjects). The plasma half-life averaged one hour, about twice that in nonelderly, healthy subjects taking omeprazole and sodium bicarbonate.
However, no dosage adjustment is necessary in the elderly [see Clinical Pharmacology (12.3)] .
🆘 Overdosage ▾
10 OVERDOSAGE If over-exposure occurs, call your Poison Control Center at 1-800-222-1222 for current information on the management of poisoning or overdosage. Omeprazole Reports have been received of overdosage with omeprazole in humans. Doses ranged up to 2,400 mg (120 times the usual recommended clinical dose).
Manifestations were variable, but included confusion, drowsiness, blurred vision, tachycardia, nausea, vomiting, diaphoresis, flushing, headache, dry mouth, and other adverse reactions similar to those seen in clinical experience with the recommended dosage [see Adverse Reactions (6)]. Symptoms were transient, and no serious clinical outcome has been reported when omeprazole was taken alone. No specific antidote for omeprazole overdosage is known.
Omeprazole is extensively protein bound and is, therefore, not readily dialyzable. In the event of overdosage, treatment should be symptomatic and supportive. Sodium Bicarbonate Overdosage of sodium bicarbonate can cause electrolyte abnormalities (hypocalcemia, hypokalemia, hypernatremia), metabolic alkalosis, and seizures.
Institute supportive care and correct electrolyte abnormalities.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Omeprazole belongs to a class of antisecretory compounds, the substituted benzimidazoles, that suppress gastric acid secretion by specific inhibition of the H+/K+ ATPase enzyme system at the secretory surface of the gastric parietal cell. Because this enzyme system is regarded as the acid (proton) pump within the gastric mucosa, omeprazole has been characterized as a gastric acid-pump inhibitor, in that it blocks the final step of acid production. This effect is dose related and leads to inhibition of both basal and stimulated acid secretion irrespective of the stimulus.
12.2Pharmacodynamics Antisecretory Activity Results from a pharmacokinetic/pharmacodynamic (PK/PD) study of the antisecretory effect of repeated once-daily dosing of 40 mg and 20 mg of omeprazole and sodium bicarbonate for oral suspension in healthy subjects are shown in Table 8 below. Table 8: Effect of Omeprazole and Sodium Bicarbonate for Oral Suspension on Intragastric pH, Day 7 Once-Daily Dosage of Omeprazole and Sodium Bicarbonate for Oral Suspension Parameter 40 mg omeprazole and 1,680 mg sodium bicarbonate (n = 24) 20 mg omeprazole and 1,680 mg sodium bicarbonate (n = 28) % Decrease from Baseline for Integrated Gastric Acidity (mmol•hr/L) 84% 82% Coefficient of Variation 20% 24% % Time Gastric pH > 4 1 (Hours) 1 77% (18.6 h) 51% (12.2 h) Coefficient of Variation 27% 43% Median pH 5.2
4.2Coefficient of Variation 17% 37% Note: Values represent medians. All parameters were measured over a 24-hour period. 1.
P < 0.05 20 mg vs. 40 mg Results from a separate PK/PD study of antisecretory effect on repeated once-daily dosing of 40 mg/1,100 mg and 20 mg/1,100 mg of ZEGERID capsules in healthy subjects show similar effects in general on the above three PD parameters as those for omeprazole and sodium bicarbonate for oral suspension 40 mg/1,680 mg and 20 mg/1,680 mg, respectively. The antisecretory effect lasts longer than would be expected from the very short (1 hour) plasma half-life, apparently due to irreversible binding to the parietal H+/K+ ATPase enzyme.
Enterochromaffin-like (ECL) Cell Effects Human gastric biopsy specimens have been obtained from more than 3000 patients treated with omeprazole in long-term clinical trials. The incidence of ECL cell hyperplasia in these studies increased with time; however, no case of ECL cell carcinoids, dysplasia, or neoplasia has been found in these patients. These studies are of insufficient duration and size to rule out the possible influence of long-term administration of omeprazole on the development of any premalignant or malignant conditions.
Serum Gastrin Effects In studies involving more than 200 patients, serum gastrin levels increased during the first 1 to 2 weeks of once-daily administration of therapeutic doses of omeprazole in parallel with inhibition of acid secretion. No further increase in serum gastrin occurred with continued treatment. In comparison with histamine H2-receptor antagonists, the median increases produced by 20 mg doses of omeprazole were higher (1.3 to 3.6-fold vs.
1.1- to 1.8-fold increase). Gastrin values returned to pretreatment levels, usually within 1 to 2 weeks after discontinuation of therapy. Increased gastrin causes enterochromaffin-like cell hyperplasia and increased serum Chromogranin A (CgA) levels.
The increased CgA levels may cause false positive results in diagnostic investigations for neuroendocrine tumors [see Warnings and Precautions (5.11)] . Other Effects Systemic effects of omeprazole in the central nervous system (CNS), cardiovascular and respiratory systems have not been found to date. Omeprazole, given in oral doses of 30 or 40 mg for 2 to 4 weeks, had no effect on thyroid function, carbohydrate metabolism, or circulating levels of parathyroid hormone, cortisol, estradiol, testosterone, prolactin, cholecystokinin or secretin.
No effect on gastric emptying of the solid and liquid components of a test meal was demo…

📋 Description ▾
11 DESCRIPTION Omeprazole and sodium bicarbonate for oral suspension is a combination of omeprazole, a proton-pump inhibitor, and sodium bicarbonate, an antacid. Omeprazole is a substituted benzimidazole, 5-methoxy-2-[[(4-methoxy-3,5-dimethyl-2pyridinyl)methyl]sulfinyl]-1 H -benzimidazole, a racemic mixture of two enantiomers that inhibits gastric acid secretion. Its empirical formula is C 17 H 19 N 3 O 3 S, with a molecular weight of 345.42.
The structural formula is: Omeprazole is a white to off-white crystalline powder which melts with decomposition at about 155°C. It is a weak base, freely soluble in ethanol and methanol, slightly soluble in acetone and isopropanol and very slightly soluble in water. The stability of omeprazole is a function of pH; it is rapidly degraded in acid media but has acceptable stability under alkaline conditions.
Omeprazole and sodium bicarbonate is supplied as unit-dose packets as powder for oral suspension. Packets of powder for oral suspension contain either 40 mg or 20 mg of omeprazole and 1,680 mg of sodium bicarbonate with the following excipients: banana flavor (acacia, maltodextrin, medium chain triglycerides and natural flavor), sucralose, sucrose, xanthan gum, and xylitol. Omeprazole and sodium bicarbonate for oral suspension is an immediate-release formulation that contain sodium bicarbonate which raises the gastric pH and thus protects omeprazole from acid degradation. structure
