Application Number:	15/385,447
Patent Claims:	1. A pharmaceutical composition of gamma-hydroxybutyrate (GHB) comprising a mixture of salts of GHB, wherein the mixture consists of a sodium salt of gamma-hydroxybutyrate (NaGHB), a potassium salt of gamma-hydroxybutyrate (KGHB), a magnesium salt of gamma-hydroxybutyrate (Mg(GHB).sub.2), and a calcium salt of gamma-hydroxybutyrate (Ca(GHB).sub.2), wherein the NaGHB, KGHB, Mg(GHB).sub.2, and Ca(GHB).sub.2 salts are present in a wt/wt % ratio of about 8%:23%:21%:48%, respectively, wherein the composition is formulated as a liquid formulation, and wherein the liquid formulation has a total concentration of GHB salts of about 350 mg/mL to about 650 mg/mL. 2. The pharmaceutical composition of claim 1, wherein the total concentration of GHB salts is about 500 mg/mL. 3. The pharmaceutical composition of claim 1, wherein the composition has a pH of about 7.0 to about 9.0. 4. The pharmaceutical composition of claim 1, wherein the composition is chemically stable and resistant to microbial growth, and wherein the composition is free of preservatives. 5. A pharmaceutical composition of gamma-hydroxybutyrate (GHB) comprising a mixture of salts of GHB, wherein the mixture consists of a sodium salt of gamma-hydroxybutyrate (NaGHB), a potassium salt of gamma-hydroxybutyrate (KGHB), a magnesium salt of gamma-hydroxybutyrate (Mg(GHB).sub.2), and a calcium salt of gamma-hydroxybutyrate (Ca(GHB).sub.2), wherein the NaGHB, KGHB, Mg(GHB).sub.2, and Ca(GHB).sub.2 salts are present in a wt/wt % ratio of about 8%:23%:21%:48%, respectively, wherein the composition is in a solid formulation. 6.
