Randomized Controlled Trial Comparative StudyCombination of citalopram plus paliperidone is better than citalopram alone in the treatment of somatoform disorder: results of a 6-week randomized study.
The objective of this study was to evaluate the effectiveness and tolerability of citalopram versus citalopram plus paliperidone combination therapy in patients with somatoform disorders (SDs). In this 6-week, randomized, fixed-dose study, 60 patients with SD (ICD-10 F45.0), undifferentiated SD (F45.1), and somatoform autonomic dysfunction (F45.3) were randomly assigned to receive citalopram (20 mg/day) with or without paliperidone (3 mg/day). ⋯ Our findings indicate that a combination with paliperidone is significantly better than monotherapy with citalopram whether synergistic or add-on for patients with SDs. Our results call for future studies with larger sample sizes and a longer duration to draw more definitive conclusions.

Randomized Controlled Trial Multicenter StudyAdjunctive therapy with pregabalin in generalized anxiety disorder patients with partial response to SSRI or SNRI treatment.
This study evaluated the efficacy of adjunctive pregabalin versus placebo for treatment of patients with generalized anxiety disorder (GAD) who had not optimally responded to previous or prospective monotherapies. This was a phase 3, randomized, double-blind, placebo-controlled study. Patients diagnosed with GAD who had a historical and current lack of response to pharmacotherapy [Hamilton Anxiety Rating Scale (HAM-A) of ≥ 22 at screening] were randomized to adjunctive treatment with either pregabalin (150-600 mg/day) or placebo. ⋯ Adverse events were consistent with previous studies and discontinuations were infrequent for pregabalin (4.4%) and placebo (2.3%). The study was discontinued early after an interim analysis. The results indicate that adjunctive pregabalin is an efficacious therapy for patients with GAD who experience an inadequate response to established treatments.
