  • Publication number: 20250120951
    Abstract: A liquid pharmaceutical composition for the treatment of an epilepsy disorder comprising clemizole HCl, a solvent, a preservative, and glycerol. The preservative and the clemizole HCl are stable during storage. The preservative comprises at least one of methyl parahydroxybenzoate, or ethyl parahydroxybenzoate. The solvent is a citrate buffer and the liquid pharmaceutical composition has a pH of 4 to 5. A method of preparing the liquid pharmaceutical composition by dissolving the clemizole HCl, the preservative, and the excipients in at least one of the solvent, a solubilizer, or a combined solvent-solubilizer solution. The method further comprises adding glycerol and adjusting the pH to 4 to 5. A method of treating a subject having an epilepsy disorder comprising administering the liquid pharmaceutical composition.
