These agents are essential for normal metabolic processes.

Pyridoxine (vitamin B-6; Aminoxin, Pyri-500)

Two distinct treatment situations exist in which pyridoxine is used in patients with West syndrome.

First is intravenous (IV) administration during diagnostic EEG to assess whether the patient's seizures and EEG abnormalities are related to pyridoxine deficiency. In this approach, administer 50-100 mg IV during a diagnostic EEG; if dramatic improvement is noted in the EEG, the patient is believed to have pyridoxine-dependent seizures.

Second is long-term oral administration. The effectiveness of long-term, oral, high-dose pyridoxine in West syndrome has been investigated in multiple open-label studies, with promising results. Most patients who respond to long-term, oral, high-dose pyridoxine do so within 1-2 weeks of initiation.

However, a 2004 American Academy of Neurology and Child Neurology Society practice parameter concluded that "there is insufficient evidence to recommend pyridoxine for the treatment of infantile spasms (Level U, Class III and IV evidence)."
