Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Drug:PregabalinPregabalin administered as either capsule or liquid oral formulations. Subjects <4 years of age at Visit 1 will receive study medication 3 times daily (TID) in equally divided doses. Subjects who are ≥4 years of age at Visit 1 will receive study medication twice daily (BID) in equally divided doses. Children less than 17 years of age will receive from 2.5 mg/kg/day to 10.0 mg/kg/day (maximum 600 mg/day. Adults 17 and older will receive from 150 mg/day to 600 mg/day.

Study Arms
