Management: Due to the possible risk for impaired clopidogrel effectiveness, clinicians should carefully consider the need for proton pump inhibitor therapy in patients receiving clopidogrel. Other acid-lowering therapies do not appear to share this interaction. Consider therapy modification

The clinical significance of short-term PPI therapy with delavirdine is uncertain, but such therapy should be undertaken with caution. Avoid combination

Dexmethylphenidate: Proton Pump Inhibitors may increase the absorption of Dexmethylphenidate. Specifically, proton pump inhibitors may interfere with the normal release of drug from the extended-release capsules (Focalin XR brand), which could result in both increased absorption (early) and decreased delayed absorption. Monitor therapy

Management: Avoid the use of PPIs at doses greater than the equivalent of omeprazole 20 mg, avoid administration of PPIs within 2 hours prior to ledipasvir dosing, and avoid use of PPIs in combination with food. Consider therapy modification

Mesalamine: Proton Pump Inhibitors may diminish the therapeutic effect of Mesalamine. Proton pump inhibitor-mediated increases in gastrointestinal pH may cause the premature release of mesalamine from specific sustained-release mesalamine products. Management: Consider avoiding concurrent administration of high-dose proton pump inhibitors (PPIs) with sustained-release mesalamine products. Consider therapy modification

Warnings/Precautions

Concerns related to adverse effects:

• Atrophic gastritis: Long-term omeprazole therapy has caused atrophic gastritis (by biopsy); this may also occur with rabeprazole.

• Carcinoma: No reports of adenomatoid, dysplastic or neoplastic changes of enterochromaffin-like (ECL) cells in the gastric mucosa have occurred.

Clostridium difficile-associated diarrhea (CDAD): Use of proton pump inhibitors (PPIs) may increase risk of CDAD, especially in hospitalized patients; consider CDAD diagnosis in patients with persistent diarrhea that does not improve. Use the lowest dose and shortest duration of PPI therapy appropriate for the condition being treated.

• Cutaneous and systemic lupus erythematosus: Has been reported as new onset or exacerbation of existing autoimmune disease; most cases were cutaneous lupus erythematosus (CLE), most commonly, subacute CLE (occurring within weeks to years after continuous therapy). Systemic lupus erythematosus (SLE) is less common (typically occurs within days to years after initiating treatment) and occurred primarily in young adults up to the elderly. Discontinue therapy if signs or symptoms of CLE or SLE occur and refer to specialist for evaluation; most patients improve 4 to 12 weeks after discontinuation of rabeprazole.

• Fractures: Increased incidence of osteoporosis-related bone fractures of the hip, spine, or wrist may occur with proton pump inhibitor (PPI) therapy. Patients on high-dose (multiple daily doses) or long-term therapy (≥1 year) should be monitored. Use the lowest effective dose for the shortest duration of time, use vitamin D and calcium supplementation, and follow appropriate guidelines to reduce risk of fractures in patients at risk.

• Gastrointestinal infection (eg, Salmonella, Campylobacter): Use of proton pump inhibitors may increase risk of these infections.

• Hypomagnesemia: Reported rarely, usually with prolonged PPI use of ≥3 months (most cases >1 year of therapy). May be symptomatic or asymptomatic; severe cases may cause tetany, seizures, and cardiac arrhythmias. Consider obtaining serum magnesium concentrations prior to beginning long-term therapy, especially if taking concomitant digoxin, diuretics, or other drugs known to cause hypomagnesemia; and periodically thereafter. Hypomagnesemia may be corrected by magnesium supplementation, although discontinuation of rabeprazole may be necessary; magnesium levels typically return to normal within 1 week of stopping.

• Interstitial nephritis: Acute interstitial nephritis has been observed in patients taking PPIs; may occur at any time during therapy and is generally due to an idiopathic hypersensitivity reaction. Discontinue if acute interstitial nephritis develops.

• Vitamin B12 deficiency: Prolonged treatment (>3 years) may lead to vitamin B12 malabsorption and subsequent vitamin B12 deficiency. The magnitude of the deficiency is dose-related and the association is stronger in females and those younger in age (<30 years); prevalence is decreased after discontinuation of therapy (Lam 2013).

Disease-related concerns:

• Gastric malignancy: Relief of symptoms does not preclude the presence of a gastric malignancy.

• Hepatic impairment: Avoid use in patients with severe hepatic impairment; if treatment is necessary monitor for adverse reactions.

Concurrent drug therapy issues:

• Clopidogrel: Proton pump inhibitors (PPIs) may diminish the therapeutic effect of clopidogrel, thought to be due to reduced formation of the active metabolite of clopidogrel. The manufacturer of clopidogrel recommends either avoidance of both omeprazole (even when scheduled 12 hours apart) and esomeprazole or use of a PPI with comparatively less effect on the active metabolite of clopidogrel. Avoidance of rabeprazole appears prudent due to potent in vitro CYP2C19 inhibition (Li 2004) and lack of sufficient comparative in vivo studies with other PPIs. In contrast to these warnings, others have recommended the continued use of PPIs, regardless of the degree of inhibition, in patients with a history of GI bleeding or multiple risk factors for GI bleeding who are also receiving clopidogrel since no evidence has established clinically meaningful differences in outcome; however, a clinically-significant interaction cannot be excluded in those who are poor metabolizers of clopidogrel (Abraham 2010; Levine 2011).

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Other warnings/precautions:

• Appropriate use: Helicobacter pylori eradication: Short-term combination therapy (≤7 days) has been associated with a higher incidence of treatment failure. The American College of Gastroenterology recommends 10 to 14 days of therapy (triple or quadruple) for eradication of H. pylori (Chey 2007).

Monitoring Parameters

Magnesium levels (prior to initiation of therapy and periodically thereafter) in patients on long-term treatment or those taking digoxin, diuretics, or other drugs that cause hypomagnesemia; susceptibility testing recommended in patients who fail H. pylori eradication regimen.

Pregnancy Considerations

Available studies have not shown an increased risk of major birth defects following maternal use of proton pump inhibitors during pregnancy; however, information specific to rabeprazole is limited (Pasternak 2010); most information available for omeprazole. When treating GERD in pregnancy, PPIs may be used when clinically indicated (Katz 2013).

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Patient may experience headache, diarrhea, constipation, flatulence, or pharyngitis. Have patient report immediately to prescriber signs of low magnesium (mood changes; muscle pain or weakness; muscle cramps or spasms; seizures; tremors; lack of appetite; severe nausea or vomiting; or an abnormal heartbeat), signs of kidney problems (urinary retention, blood in urine, change in amount of urine passed, or weight gain), severe dizziness, passing out, severe abdominal pain, bone pain, chills, excessive weight loss, severe loss of strength and energy, signs of Clostridium difficile (C. diff)-associated diarrhea (stomach pain or cramps, very loose or watery stools, or bloody stools), or signs of Stevens-Johnson syndrome/toxic epidermal necrolysis (red, swollen, blistered, or peeling skin [with or without fever]; red or irritated eyes; or sores in mouth, throat, nose, or eyes) (HCAHPS).

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
