The present invention relates to the use of selective
aquaporin inhibitors, e.g., of
aquaporin-4 or
aquaporin-2, e.g., certain phenylbenzamide compounds, for the prophylaxis, treatment and control of aquaporin-mediated conditions, e.g., diseases of water imbalance, for example
edema (particularly
edema of the brain and
spinal cord, e.g., following trauma or
ischemic stroke, as well as the
edema associated with
glioma,
meningitis, acute mountain sickness, epileptic seizures, infections, metabolic disorders, hypoxia, water intoxication, hepatic failure,
hepatic encephalopathy, diabetic ketoacidosis,
abscess,
eclampsia, Creutzfeldt-Jakob
disease, and lupus cerebritis, as well as edema consequent to microgravity and / or
radiation exposure, as well as edema consequent to invasive
central nervous system procedures, e.g.,
neurosurgery, endovascular clot removal, spinal tap,
aneurysm repair, or
deep brain stimulation, as well as
retinal edema), as well as
hyponatremia and excess fluid retention, and diseases such as
epilepsy,
retinal ischemia and other diseases of the eye associated with abnormalities in
intraocular pressure and / or tissue hydration,
myocardial ischemia,
myocardial ischemia /
reperfusion injury,
myocardial infarction, myocardial hypoxia, congestive
heart failure,
sepsis, and
neuromyelitis optica, as well as migraines, as well as to novel assays for identifying aquaporin inhibitors.
