Abstract

A method of treating and/or preventing Dravet Syndrome in a patient such as a patient previously diagnosed with Dravet Syndrome, by administering an effective dose of fenfluramine or its pharmaceutically acceptable salt to that patient.

administering to the patient 0.2 mg/kg/day of fenfluramine or a pharmaceutically acceptable salt thereof; and

administering to the patient an effective dose of stiripentol or a pharmaceutically acceptable salt thereof to said patient;

whereby seizures are ameliorated in the patient.

2. A method of adjunctive treatment of seizures in a patient diagnosed with Dravet syndrome and exhibiting a mutation in a gene, comprising:

administering to the patient 0.2 mg/kg/day of fenfluramine or a pharmaceutically acceptable salt thereof; and

(b) an effective dose of stiripentol or a pharmaceutically acceptable salt thereof;

whereby seizures are ameliorated in the patient exhibiting the mutation.

5. The method as claimed in claim 4 , wherein the mutation is in a gene selected from the group consisting of SCN1A, SCN1B, SCN2A, SCN3A, SCN9A, GABRG2, GABRD and PCDH19.

6. A method of adjunctive treatment of seizures in a patient diagnosed with Dravet syndrome, comprising:

administering to the patient an effective dose of fenfluramine or a pharmaceutically acceptable salt thereof, wherein the fenfluramine or pharmaceutically acceptable salt thereof is administered in a dose of 0.5 mg/kg/day to 0.2 mg/kg/day to the patient; and
