Dosage of Omey in details

Omey Delayed-Release Capsules should be taken before eating. In the clinical trials, antacids were used concomitantly with Omey.

Patients should be informed that the Omey Delayed-Release Capsule should be swallowed whole.

For patients unable to swallow an intact capsule, alternative administration options are available.

Short-Term Treatment Of Active Duodenal Ulcer

The recommended adult oral dose of Omey is 20 mg once daily. Most patients heal within four weeks. Some patients may require an additional four weeks of therapy.

H. pylori Eradication For The Reduction Of The Risk Of Duodenal Ulcer Recurrence

Triple Therapy (Omey/clarithromycin/amoxicillin)

The recommended adult oral regimen is Omey 20 mg plus clarithromycin 500 mg plus amoxicillin 1000 mg each given twice daily for 10 days. In patients with an ulcer present at the time of initiation of therapy, an additional 18 days of Omey 20 mg once daily is recommended for ulcer healing and symptom relief.

Dual Therapy (Omey/clarithromycin)

The recommended adult oral regimen is Omey 40 mg once daily plus clarithromycin 500 mg three times daily for 14 days. In patients with an ulcer present at the time of initiation of therapy, an additional 14 days of Omey 20 mg once daily is recommended for ulcer healing and symptom relief.

Gastric Ulcer

The recommended adult oral dose is 40 mg once daily for 4-8 weeks.

Gastroesophageal Reflux Disease (GERD)

The recommended adult oral dose for the treatment of patients with symptomatic GERD and no esophageal lesions is 20 mg daily for up to 4 weeks. The recommended adult oral dose for the treatment of patients with erosive esophagitis and accompanying symptoms due to GERD is 20 mg daily for 4 to 8 weeks.

Maintenance Of Healing Of Erosive Esophagitis

The recommended adult oral dose is 20 mg daily. Controlled studies do not extend beyond 12 months.

Pathological Hypersecretory Conditions

The dosage of Omey in patients with pathological hypersecretory conditions varies with the individual patient. The recommended adult oral starting dose is 60 mg once daily. Doses should be adjusted to individual patient needs and should continue for as long as clinically indicated. Doses up to 120 mg three times daily have been administered. Daily dosages of greater than 80 mg should be administered in divided doses. Some patients with Zollinger-Ellison syndrome have been treated continuously with Omey for more than 5 years.

Pediatric Patients

For the treatment of GERD and maintenance of healing of erosive esophagitis, the recommended daily dose for pediatric patients 1 to 16 years of age is as follows:

Patient Weight	Omey Daily Dose
5 < 10 kg	5 mg
10 < 20 kg	10 mg
≥ 20 kg	20 mg

On a per kg basis, the doses of Omey required to heal erosive esophagitis in pediatric patients are greater than those for adults.

Alternative administrative options can be used for pediatric patients unable to swallow an intact capsule.

Alternative Administration Options

Omey is available as a delayed-release capsule or as a delayed-release oral suspension.

For patients who have difficulty swallowing capsules, the contents of a Omey Delayed-Release Capsule can be added to applesauce.

One tablespoon of applesauce should be added to an empty bowl and the capsule should be opened. All of the pellets inside the capsule should be carefully emptied on the applesauce. The pellets should be mixed with the applesauce and then swallowed immediately with a glass of cool water to ensure complete swallowing of the pellets. The applesauce used should not be hot and should be soft enough to be swallowed without chewing. The pellets should not be chewed or crushed. The pellets/applesauce mixture should not be stored for future use.

Omey For Delayed-Release

Oral Suspension should be administered as follows:

• Empty the contents of a 2.5 mg packet into a container containing 5 mL of water.
• Empty the contents of a 10 mg packet into a container containing 15 mL of water.
• Stir
• Leave 2 to 3 minutes to thicken.
• Stir and drink within 30 minutes.
• If any material remains after drinking, add more water, stir and drink immediately.

For patients with a nasogastric or gastric tube in place:

• Add 5 mL of water to a catheter tipped syringe and then add the contents of a 2.5 mg packet (or 15 mL of water for the 10 mg packet). It is important to only use a catheter tipped syringe when administering Omey through a nasogastric tube or gastric tube.
• Immediately shake the syringe and leave 2 to 3 minutes to thicken.
• Shake the syringe and inject through the nasogastric or gastric tube, French size 6 or larger, into the stomach within 30 minutes.
• Refill the syringe with an equal amount of water.
• Shake and flush any remaining contents from the nasogastric or gastric tube into the stomach.

Tell your doctor about all your current medicines. Many drugs can affect Omey + SyrSpend SF Alka, especially:

• clopidogrel;

• methotrexate;

• St. John's wort; or

• an antibiotic--amoxicillin, clarithromycin, rifampin.

This list is not complete and many other drugs may affect Omey + SyrSpend SF Alka. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.

Drug Interactions (in more detail)

Omey interactions

Effects of Omey on the Pharmacokinetics of Other Drugs: The following combination with Omey should be avoided: Ketoconazole and itraconazole.

Omey might influence the absorption of other drugs due to its effect on the gastric pH. The dissolution of ketoconazole tablets in the stomach is adversely affected if the pH of the gastric juice increases as a result of drug treatment (antacids, secretion-inhibiting agents, sucralfate). This leads to ineffective plasma concentrations of ketoconazole. During concomitant administration of Omey and itraconazole, the plasma concentration and area under the curve (AUC) of itraconazole are reduced by approximately 65%, probably as a result of poorer absorption, which is dependent on pH.

Omey inhibits the enzyme CYP2C19 and therefore, increased plasma levels of other drugs (diazepam, warfarin, phenytoin) metabolized via this enzyme might be expected. Monitoring is recommended during initiation or withdrawal of Omey in patients being treated with phenytoin, warfarin or other vitamin K antagonist.

During concomitant administration of clarithromycin or erythromycin and Omey, the plasma concentrations of Omey were increased. The plasma concentrations of Omey are not influenced during concomitant administration with amoxicillin or metronidazole.

Concomitant administration of Omey (40 mg once daily) and atazanavir 300 mg/ritonavir 100 mg to healthy volunteers resulted in a marked reduction in total atazanavir exposure (approximately 75% reduction of AUC, C_max and C_min). An increase in the atazanavir dose to 400 mg did not compensate for the effect that Omey had on atazanavir exposure. Proton pump inhibitors including Omey should therefore not be administered concomitantly with atazanavir.

Concomitant administration of Omey and tacrolimus may increase the serum levels of tacrolimus. Monitoring of the plasma tacrolimus concentration is recommended when treatment with Omey is being initiated or discontinued. Omey (40 mg daily) increased the C_max and AUC of voriconazole (CYP2C19 substrate) by 15% and 41%, respectively.

Effects of Other Drugs on the Pharmacokinetics of Omey: Drugs inhibiting the enzymes CYP2C19 or CYP3A (HIV protease inhibitors, ketoconazole, itraconazole) might increase the plasma concentrations of Omey. Voriconazole increases the AUC of Omey by 280%. In cases of concomitant treatment, an adjustment of the Omey dose should be considered for patients with considerable impaired hepatic function and in cases of long-term treatment.

Case reports, published population pharmacokinetic studies and retrospective analyses suggest that concomitant administration of PPIs and methotrexate (primarily at high doses) may elevate and prolong serum levels of methotrexate and/or its metabolite hydroxymethotrexate. However, no formal drug interaction studies of methotrexate with PPIs have been conducted.

No interactions between Omey and antacids, theophylline, caffeine, quinidine, lidocaine, propranolol, metoprolol or ethanol have been detected.
