1. A method of treating a disorder treatable with gamma-hydroxybutyrate in a human patient in need thereof, the method comprising:
orally administering a formulation that comprises an immediate-release portion and a modified-release portion to the patient, wherein
the orally administering occurs only once nightly,
the formulation comprises an amount of gamma-hydroxybutyrate equivalent to 3.0 g, 4.5 g, 6.0 g, 7.5 g, 9.0 g, or 10.5 g of sodium oxybate,
after the orally administering, the formulation releases gamma-hydroxybutyrate into the blood stream of the patient, and
wherein the once-nightly formulation achieves a relative bioavailability (RBA) of greater than 80%.
