ORMALVI (dichlorphenamide)
ORMALVI is an oral medication used for patients with primary hyperkalemic or hypokalemic periodic paralysis. It also helps those suffering from related variants of these muscle conditions. This medication provides a therapeutic option for managing these specific types of periodic paralysis.
How ORMALVI Works
ORMALVI works by inhibiting the enzyme carbonic anhydrase. While it is classified as a carbonic anhydrase inhibitor, the exact process by which this action produces its therapeutic effects in patients with periodic paralysis is not yet known.
