Panic disorder (PD) can result in significant functional impairment. Studies of cognitive behavioral therapy (CBT) for PD have demonstrated response rates ranging between 38 and 65%. D-cycloserine (DCS), a partial NMDA agonist, may enhance the effects of exposure-based therapy for PD in adults; however, no studies have examined its effect in adolescents with PD. This study examined the feasibility and acceptability of the use of DCS to augment intensive CBT for PD in adolescents. Twenty-four adolescents (ages 12-17) participated in this randomized, double-blinded, placebo-controlled trial, to compare CBT + DCS to CBT + placebo. The results demonstrated the feasibility and acceptability of the treatment to participants. No significant differences were found between the two groups, but both groups showed significant improvement. This is the first investigation of DCS in the treatment of PD in adolescents and it provides initial support for a more extensive study of DCS augmentation of CBT among adolescents with PD.
