Aurolife Pharma, LLC

1 INDICATIONS AND USAGE

1.1 Duodenal Ulcer

Omeprazole and sodium bicarbonate capsules are indicated for short-term treatment of active duodenal ulcer. Most patients heal within four weeks. Some patients may require an additional four weeks of therapy. [See Clinical Studies (14.1)]

1.2 Gastric Ulcer

Omeprazole and sodium bicarbonate capsules are indicated for short-term treatment (4 to 8 weeks) of active benign gastric ulcer. [See Clinical Studies (14.2)]

1.3 Treatment of Gastroesophageal Reflux Disease (GERD)

Symptomatic GERD

Omeprazole and sodium bicarbonate capsules are indicated for the treatment of heartburn and other symptoms associated with GERD. [See Clinical Studies (14.3)]

Erosive Esophagitis

Omeprazole and sodium bicarbonate capsules are indicated for the short-term treatment (4 to 8 weeks) of erosive esophagitis which has been diagnosed by endoscopy.

The efficacy of omeprazole and sodium bicarbonate used for longer than 8 weeks in these patients has not been established. If a patient does not respond to 8 weeks of treatment, it may be helpful to give up to an additional 4 weeks of treatment. If there is recurrence of erosive esophagitis or GERD symptoms (e.g., heartburn), additional 4 to 8 week courses of omeprazole and sodium bicarbonate may be considered. [See Clinical Studies (14.3)]

1.4 Maintenance of Healing of Erosive Esophagitis

Omeprazole and sodium bicarbonate capsules are indicated to maintain healing of erosive esophagitis. Controlled studies do not extend beyond 12 months. [See Clinical Studies (14.4)]

2 DOSAGE AND ADMINISTRATION

Omeprazole and sodium bicarbonate is available as a capsule in 20 mg and 40 mg strengths of omeprazole for adult use. Directions for use for each indication are summarized in Table 1.

All recommended doses throughout the labeling are based upon omeprazole.

Since both the 20 mg and 40 mg capsules contain the same amount of sodium bicarbonate (1100 mg), two capsules of 20 mg are notequivalent to one capsule of omeprazole and sodium bicarbonate 40 mg; therefore, two 20 mg capsules of omeprazole and sodium bicarbonate should not be substituted for one capsule of omeprazole and sodium bicarbonate 40 mg.

Omeprazole and sodium bicarbonate capsules should be taken on an empty stomach at least one hour before a meal.

4 CONTRAINDICATIONS


Omeprazole and sodium bicarbonate is contraindicated in patients with known hypersensitivity to any components of the formulation. Hypersensitivity reactions may include anaphylaxis, anaphylactic shock, angioedema, bronchospasm, interstitial nephritis, and urticaria. [See Adverse Reactions (6)]

5 WARNINGS AND PRECAUTIONS

5.1 Concomitant Gastric Malignancy


Symptomatic response to therapy with omeprazole does not preclude the presence of gastric malignancy.

5.2 Atrophic gastritis


Atrophic gastritis has been noted occasionally in gastric corpus biopsies from patients treated long-term with omeprazole.

5.3 Acute Interstitial Nephritis

Acute interstitial nephritis has been observed in patients taking PPIs including omeprazole and sodium bicarbonate. Acute interstitial nephritis may occur at any point during PPI therapy and is generally attributed to an idiopathic hypersensitivity reaction. Discontinue omeprazole and sodium bicarbonate if acute interstitial nephritis develops. [See Contraindications (4)].

5.4 Cyanocobalamin (vitamin B-12) Deficiency

Daily treatment with any acid-suppressing medications over a long period of time (e.g., longer than 3 years) may lead to malabsorption of cyanocobalamin (vitamin B-12) caused by hypo- or achlorhydria. Rare reports of cyanocobalamin deficiency occurring with acid-suppressing therapy have been reported in the literature. This diagnosis should be considered if clinical symptoms consistent with cyanocobalamin deficiency are observed.

5.5 Buffer Content

Each omeprazole and sodium bicarbonate capsule contains 1100 mg (13 mEq) of sodium bicarbonate. The total content of sodium in each capsule is 304 mg.

The sodium content of omeprazole and sodium bicarbonate capsules should be taken into consideration when administering to patients on a sodium restricted diet.

Because omeprazole and sodium bicarbonate capsules contain sodium bicarbonate, they should be used with caution in patients with Bartter’s syndrome, hypokalemia, hypocalcemia, and problems with acid-base balance. Long-term 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 increase.
