Cross-reactivity
Hypersensitivity to PPIs can take the form of whole group hypersensitivity, pattern A, B, or C. Whole group hypersentivity occurs when a person is cross-reactive to all PPIs; that is, all PPIs will induce the allergy. In pattern A, a person may be allergic to omeprazole, esomeprazole, and pantoprazole, but not to lansoprazole and rabeprazole. This is thought to be due to the structural similarities between omeprazole, esomeprazole, and pantoprazole, contrasted with lansoprazole and rabeprazole. Pattern B is the opposite, reflecting people that are allergic to lansoprazole and rabeprazole, but not to omeprazole, esomeprazole, and pantoprazole. Pattern C, in the context of rabeprazole, would reflect a person that is allergic to only rabeprazole, but not to other PPIs (omeprazole, esomeprazole, pantoprazole, and lansoprazole). Rilpivirine
Rilpivirine, a non-nucleoside reverse transcriptase inhibitor used in the treatment of HIV, is contraindicated with all PPIs because of their acid-suppressing effect. PPIs suppress acid, thereby raising the pH of (alkalizing) the stomachs contents. Rilpivirine is best absorbed under acidic conditions. Therefore, rabeprazole would be expected to decrease the absorption of rilpivirine, decrease the concentration of rilpivirine in the blood, and possibly lead to therapeutic failure and resistance to the medication/class. Adverse effects
In general, rabeprazole is fairly well tolerated, even up to five years after clinical trial follow-up. The side effect profile is similar to that of omeprazole. The most common side effects include headache, nausea, and diarrhea. Rare side effects include rashes, flu-like symptoms, and infections (including by the gastrointestinal pathogen Clostridium difficile).
Also, it speeds healing of nerve damage (and minimizes the extent of recent nerve trauma). Deferoxamine may modulate expression and release of inflammatory mediators by specific cell types. Research
Deferoxamine is being studied as a treatment for spinal cord injury and intracerebral hemorrhage. It is also used to induce hypoxia-like environment in mesenchymal stem cells. See also
