1 Dosing Considerations • No dose adjustment is required in patients with renal insufficiency, hepatic insufficiency, or in elderly patients. 3 Pharmacokinetics). 4 Drug-Drug Interactions). • Patients should use the lowest dose and shortest duration of PPI therapy appropriate to the condition being treated.
2 Recommended Dose and Dosage Adjustment Duodenal Ulcer Acute Therapy: The recommended adult oral dose is 20 mg given once daily. Healing usually occurs within 2 weeks. For patients not healed after this initial course of therapy, an additional 2 weeks of treatment is recommended.
Refractory Patients:
In patients with duodenal ulcer refractory to other treatment regimens, the recommended adult doses are 20 mg-40 mg given once daily. Healing is usually achieved within 4 weeks in such patients.
Gastric Ulcer Acute Therapy:
The recommended adult dose is 20 mg given once daily. Healing usually occurs within 4 weeks. For patients not healed after this initial course of therapy, an additional 4 weeks of treatment is recommended.
Refractory Patients:
In patients with gastric ulcer refractory to other treatment regimens, the recommended adult dose is 40 mg given once daily. Healing is usually achieved within 8 weeks.
Maintenance Therapy for Gastric Ulcer:
About 80% of gastric ulcer patients are H. pylori- positive, and should be treated with eradication therapy, as described below. A small percentage of patients who are H. pylori-negative will experience a disease recurrence and will require maintenance treatment with an antisecretory agent.
The recommended omeprazole dose is 20 mg once daily, increased to 40 mg once daily as necessary.
Reflux Esophagitis Acute Therapy:
The recommended adult dose is 20 mg given once daily. In most patients, healing occurs within 4 weeks. For patients not healed after this initial course of therapy, an JAMP-Omeprazole DR (Omeprazole Magnesium Delayed Release Tablets) Page 6 of 46 Protected B / Protégé B additional 4 weeks of treatment is recommended.
1 Adverse Reaction Overview Omeprazole is well tolerated. Most adverse reactions have been mild and transient, and have shown no consistent relationship with treatment. Adverse events have been recorded during controlled clinical investigations in 2,764 patients exposed to omeprazole (data taken from controlled clinical studies with omeprazole capsules) or reported from routine use.
2 Clinical Trial Adverse Reactions Clinical trials are conducted under very specific conditions. The adverse reaction rates observed in the clinical trials; therefore, may not reflect the rates observed in practice and should not be compared to the rates in the clinical trials of another drug.
Adverse reaction information from clinical trials may be useful in identifying and approximating rates of adverse drug reactions in real-world use. In a controlled clinical trial comparing omeprazole to placebo, the prevalence of adverse events with omeprazole 40 mg once daily was similar to that with placebo.
In short-term comparative double-blind studies with histamine H2-receptor antagonists, there was no significant difference in the prevalence of adverse events between omeprazole capsules and the H2-receptor antagonists. An extensive evaluation of laboratory variables has not revealed any significant changes during omeprazole treatment which are considered to be clinically important.

Refractory Patients:
For patients with reflux esophagitis refractory to other treatment regimens, the recommended adult dose is 40 mg given once daily. Healing is usually achieved within 8 weeks. , Heartburn and Regurgitation) The recommended adult dose is 20 mg given once daily.
Symptom relief should be rapid. If symptom control is not achieved after 4 weeks, further investigation is recommended. NSAID-Associated Gastric or Duodenal Ulcers The issue of whether or not eradication of H. pylori in patients with NSAID-associated ulcers might have beneficial preventive effects has not yet been settled.
Acute Therapy:
In patients with NSAID-associated gastric or duodenal ulcers, the recommended adult dose is 20 mg given once daily. Symptom resolution is rapid and healing usually occurs within 4 weeks. For those patients not healed after this initial course of therapy, an additional 4 weeks of treatment is recommended.
Maintenance Therapy:
For the prevention of relapse in patients with NSAID-associated gastric or duodenal ulcers, the recommended adult dose is 20 mg given once daily, for up to 6 months. Dyspepsia Prior to treating patients presenting with dyspeptic symptoms, it should be determined that these symptoms are originating from the upper gastrointestinal tract.
Patients presenting with alarm symptoms (see 7 WARNINGS AND PRECAUTIONS), and older patients who are at a greater risk of having a serious organic disease, should be investigated prior to the initiation of therapy. If the dyspeptic symptoms are known to be related to a diagnosis of organic disease, the appropriate treatment regimen listed in the sections above should be employed.
If the dyspeptic symptoms are not known to be related to an organic disease, the recommended daily dose of JAMP-Omeprazole DR is 20 mg once daily for 4 weeks. If after 2 weeks’ treatment the patient does not respond to therapy, or there is an early clinical indication of a lack of efficacy, the patient should be thoroughly investigated in order to rule out organic disease (see 7 WARNINGS AND PRECAUTIONS).
If there are indications of a clinical response following the initial 2 weeks of treatment, JAMP-Omeprazole DR may be continued for an additional 2 weeks. Epigastric pain/discomfort (with or without heartburn and regurgitation) as predominant symptoms are likely to respond to acid suppression therapy.
In all cases, patients who do not respond to 4 weeks’ treatment, or whose symptoms recur shortly after discontinuation of treatment, with JAMP-Omeprazole DR should be investigated for underlying organic diseases.

pylori is Omeprazole Magnesium Delayed Release Tablets 20 mg, metronidazole 500 mg and clarithromycin 250 mg, all twice daily for seven days. To ensure healing and/or symptom control, further treatment with 20 mg JAMP-Omeprazole DR once daily for up to three weeks is recommended for patients with active duodenal ulcer, and with 20-40 mg omeprazole once daily for up to twelve weeks for patients with active gastric ulcer.
Patient compliance with treatment regimens for the eradication of H. pylori has been demonstrated to have a positive effect on eradication outcome. In clinical trials, patients treated with triple therapy regimens have shown high compliance rates.

The following adverse events (at a rate of more than 1%) were recorded during controlled clinical trials in 494 patients receiving omeprazole, metronidazole and clarithromycin: taste disturbances (14%), diarrhea (13%), headache (6%), ALT increased (6%), flatulence (5%), nausea (5%), AST increased (5%), dyspepsia (3%), dry mouth (2%), dizziness/vertigo (2%), epigastric pain (1%), pharyngitis (1%), eructation (1%) and fatigue (1%).
Clinical experience with the use of omeprazole magnesium 20 mg tablet is limited. In two short- term studies (20 mg tablet once daily for a maximum duration of 7 days) in a limited number of patients with duodenal ulcer in remission, the adverse event profile seen with the omeprazole magnesium 20 mg tablet is similar to that seen with the omeprazole magnesium 20 mg capsule.
5 Post-Market Adverse Reactions Gastrointestinal disorders Withdrawal of long-term PPI therapy can lead to aggravation of acid related symptoms and may result in rebound acid hypersecretion. There have been post-marketing reports of microscopic colitis and fundic gland polyps (PGPs) (see 7 WARNINGS AND PRECAUTIONS).
