PHARMACOLOGY

The proton pump inhibitor Esomeprazole inhibits gastric acid by blocking the hydrogen-potassium adenosine triphosphatase enzyme system (the proton pump) of the gastric parietal cell. Proton pump inhibitors are effective for short-term treatment of gastric and duodenal ulcers. Esomeprazole is also used in the prevention and treatment of NSAID associated gastric ulcers.

DOSAGE

Adults (from the age of 18 years)-Gastroesophageal reflux disease (GERD):

Non-erosive reflux disease (NERD) (i.e. heartburn and regurgitation): 20 mg Once daily for 24 weeks
Maintenance treatment of NERD (i.e. heartburn and regurgitation): 20 mg Once daily
Reflux esophagitis or erosive esophagitis: 20 mg or 40 mg Once daily for 4-8 weeks
Maintenance therapy of healing of reflux esophagitis: 20 mg Once daily

Healing of NSAID associated gastric ulcers: 20 mg Once daily for 4-8 weeksRisk reduction of NSAID associated gastric ulcers: 20 mg Once dailyZollinger-Ellison Syndrome: 40 mg Twice dailyH. pylori eradication (Esomeprazole with amoxicillin 1000 mg and clarithromycin 500 mg): 20 mg tab. twice daily for 7 days or 40 mg cap. once daily for 10 daysPediatrics (12 to 17 years)-Gastroesophageal reflux disease (GERD):

Non-erosive reflux disease (NERD) (i.e. heartburn and regurgitation): 20 mg Once daily for 2-4 weeks
Reflux esophagitis or erosive esophagitis: 20 mg or 40 mg Once daily for 4-8 weeks.

INTERACTION

Esomeprazole is extensively metabolized in the liver by CYP2C19 and CYP3A4. In vitro and in vivo studies have shown that Esomeprazole is not likely to inhibit CYPs 1A2, 2A6, 2C9, 2D6, 2E1 and 3A4. No clinically relevant interactions with drugs metabolized by these CYP enzymes would be expected. Drug interaction studies have shown that Esomeprazole does not have any clinically significant interactions with phenytoin, warfarin, quinidine, clarithromycin or amoxicillin. Esomeprazole may potentially interfere with CYP2C19, the major Esomeprazole metabolizing enzyme. Co-administration of Esomeprazole 30 mg anddiazepam, a CYP2C19 substrate has resulted in a 45% decrease in clearance of diazepam. Increased plasma levels of diazepam have been observed 12 hours after dosing and onwards. Esomeprazole inhibits gastric acid secretion. Therefore, Esomeprazole may interfere with the absorption of drugs where gastric pH is an important determinant of bioavailability (e.g., ketoconazole, iron salts and digoxin). Co-administration of oral contraceptives, diazepam, phenytoin, or quinidine do not seem to change the pharmacokinetic profile of Esomeprazole. Combination Therapy with Clarithromycin: Co-administration of esomeprazole, clarithromycin, and amoxicillin has resulted in increases in the plasma levels of esomeprazole and 14-hydroxyclarithromycin.

SIDE EFFECTS

The most common side effects of esomeprazole are nausea, vomiting, abdominal pain, flatulence, diarrhea, constipation and headache. Less frequent side effects include dry mouth, peripheral edema, dizziness, sleep disturbances, fatigue, paraesthesia, arthralgia, myalgia, rash and pruritus. Other side effects reported rarely or very rarely include taste disturbance, stomatitis, hepatitis, jaundice, hypersensitivity reactions (including anaphylaxis, bronchospasm), fever, depression, hallucinations, confusion, gynaecomastia, interstitial nephritis, hyponatraemia, blood disorders (including leucopenia, leukocytosis, pancytopenia, thrombocytopenia), visual disturbances, sweating, photosensitivity, alopecia, Stevens-Johnson Syndrome and toxic epidermal necrolysis.

PREGNANCY & LACTATION

Pregnancy: For esomeprazole, limited clinical data on exposed pregnancies are available. Esomeprazole should only be given to pregnant women if its use is considered essential.Lactation: It is not known whether esomeprazole is excreted in breast milk. Therefore esomeprazole should not be used during breast-feeding.

PRECAUTIONS & WARNINGS

Esomeprazole should be used carefully if the patient has severe liver dysfunction and severe renal impairment. Taking a proton pump inhibitor like Esomeprazole may slightly increase the risk of hip, wrist and spine fracture, particularly when it is taken over a period of more than one year.
