Research
An alternative formulation of rabeprazole, termed "rabeprazole-ER" (extended release) has been developed. The purpose of the formulation was to increase the half-life of rabeprazole, which normally is very short in humans. Rabeprazole-ER was a 50 mg capsule composed of five non-identical 10 mg tablets that were designed to release rabeprazole at differing intervals throughout the gastrointestinal system. However, because two high quality clinical trials failed to demonstrate a benefit of rabeprazole-ER versus esomeprazole (another common PPI) for healing grade C or D erosive esophagitis, the development of rabeprazole-ER ceased.

Abdominal migraine is a variant type of migraine. It primarily affects children, and is rare in adults. It mainly causes episodes of abdominal pain without an accompanying headache. It is poorly understood. It is difficult to confirm the diagnosis, as periumbilical abdominal pain has an extensive differential diagnosis. It may be treated with analgesia in some patients, and other medications. Avoiding triggers can prevent an episode of abdominal migraine. Signs and Symptoms
Symptoms of abdominal migraine may include:

Abdominal pain
Nausea
Vomiting
Headache
Photosensitivity
Loss of appetite
PallorThese occur in distinct episodes. This can have a significant effect on day-to-day life. It usually does not occur with a headache. Body mass index is usually unaffected, and physical development is normal. Causes
Common migraine triggers may trigger abdominal migraines. Psychological stress (such as from school), a change in location (such as travel), changes to sleep, and exercise when this is not wanted, may all cause abdominal migraine. Pathophysiology
Abdominal migraine is poorly understood. Diagnosis
As with other types of migraines, there is no diagnostic test to identify abdominal migraines. Diagnosis is based on symptoms, a family history of migraines, and eliminations of other possible causes. It can take time before a diagnosis is made, as symptoms are not specific to abdominal migraine.Diagnostic criteria from the International Classification of Headache Disorders are:

A. At least 5 attacks fulfilling criteria B-D.
B.
