Long-term maintenance and discontinuation of imipramine therapy in panic disorder with agoraphobia.
BACKGROUND There has been little systematic work done regarding the long-term treatment of panic disorders . The aim of the present study was to assess the 12-month cumulative risk of relapse specifically due to discontinuation of imipramine and to test the hypothesis that maintenance treatment with imipramine protects patients with panic disorder and agoraphobia from such reversals . METHOD Following an acute-phase open trial with imipramine ( 2.25 mg/kg per day ) involving 110 patients for 6 months , the 56 patients who were in stable remission , did not require additional treatment , and consented to be r and omly assigned to double-blind maintenance ( n = 29 ) or discontinuation ( n = 27 ) conditions were followed up with planned assessment s every 2 months during a 1-year period . There were no behaviorally oriented interventions or instructions at any time during the 18 months of the study . RESULTS Maintenance treatment ( 1 relapse ) and discontinuation ( 10 relapses ) conditions had significantly different survival curves ( Mantel-Cox statistic chi(2)1 = 10.47 , P = .001 ) . None of the additional 10 variables from demographic , clinical , and open-treatment domains considered in the proportional hazard model disrupted the significant relationship between experimental drug condition and relapse ; other things being equal , a patient receiving imipramine maintenance was 92.5 % lower in the hazard rate of relapse than a patient receiving placebo . CONCLUSION The results confirm the very high degree of prophylactic effectiveness of maintenance imipramine treatment and demonstrate that relapse , although substantial , occurs in a minority of patients with panic disorder and agoraphobia who are in stable remission prior to treatment discontinuation
