SummaryPanic disorder is a chronic condition for many patients and can be socially, emotionally and occupationally disabling. Until recently, clomipramine and alprazolam were the only drugs approved for its treatment. While widely used in the US and Europe, both belong to drug classes (tricyclics and benzodiazepines) with well-recognised side effects that can be problematic and thus limit their use. Recently, paroxetine became the first selective serotonin reuptake inhibitor to receive approval and licensing for panic disorder.The short- and long-term efficacy and tolerability of paroxetine in panic disorder has been established in clinical trials of almost 1,000 patients meeting Diagnostic and Statistical Manual (DSM)-IIIR criteria for panic disorder, with or without agoraphobia. In a 12-week double-blind study of 120 panic patients receiving standardised cognitive therapy, paroxetine was significantly more effective than placebo in reducing panic attack frequency. In a 12-week placebo-controlled comparison in 367 panic patients, paroxetine was at least as effective as clomipramine and better tolerated. There was also some evidence that paroxetine had an earlier onset of action than clomipramine.A 9-month extension of the placebo-controlled comparison with clomipramine showed that the efficacy of paroxetine and clomipramine is maintained when treatment is continued into the longer term. In a relapse prevention study, 105 responders to 3 months' treatment with paroxetine or placebo were re-randomised, either to continue existing treatment or to receive placebo for 3 months. Only 5% of patients who continued to take paroxetine experienced a relapse compared with 30% of those who switched to placebo (P = 0.002). Paroxetine was generally well tolerated. In the short-term trials, the frequency of withdrawals due to adverse events (7.3%) was lower than that for placebo (11.4%) or clomipramine (14.9%). In the longer term, the dropout rate due to adverse events increased in the clomipramine group (19.0%) but was unchanged in the paroxetine group (7.4%). Since most patients with panic disorder will require prolonged treatment, the long-term tolerability of paroxetine and its lack of potential for dependence are important advantages that will encourage good compliance with treatment and improve the quality of life of patients.

Abstract. Quinagolide (CV 205-502, Sandoz), an octahydrobenzo (g) quinoline, is a new non-ergot dopamine agonist which has specific D2 receptor activity and a long half-life, making it suitable for once-daily treatment. Recent uncontrolled reports have suggested that quinagolide may be successfully used for the clinical management of hyperprolactinemia with fewer adverse reactions than bromocriptine. This study is the first to compare quinagolide in a double-blind manner with bromocriptine, given only once-daily instead of the usual multidose regimen. In the first phase we compared, in 7 hyperprolactinemic patients, the effects over 24 h of a single oral dose of 0.05 mg quinagolide with 2.5 mg bromocriptine. Compared with placebo, both bromocriptine and quinagolide showed potent PRL-inhibiting and GH-releasing effects, with comparable effects at 24 h; no significant changes were observed in TSH, LH, FSH or cortisol. Twelve hyperprolactinemic patients were then randomized to receive either once-daily bromocriptine or quinagolide in incremental doses for a period of six months. Both drugs were found to be equally effective, and no differences were seen either in adverse reactions or PRL levels during repeated diurnal sampling. We therefore conclude that quinagolide and bromocriptine are therapeutically equivalent in long-term use, and both are equally effective when given once a day. However, some patients intolerant of bromocriptine may respond better to quinagolide, and vice versa.

BackgroundVenlafaxine extended-release (ER) has proven efficacy in the treatment of anxiety symptoms in major depression, generalised anxiety disorder and social anxiety disorder.AimsTo evaluate the efficacy, safety and tolerability of venlafaxine ER in treating panic disorder.MethodAdult out-patients (n=361) with panic disorder were randomly assigned to receive venlafaxine ER (75–225 mg/day) or placebo for up to 10 weeks in a double-blind study.ResultsVenlafaxine ER was not associated with a greater proportion of patients free from full-symptom panic attacks at the finalon-therapy evaluation, but was associated with lower mean panic attack frequency and a higher proportion free from limited-symptom panic attacks, higher response and remission rates, and improvements in anticipatory anxiety, fear and avoidance. Adverse events were comparable with those of the drug in depression and anxiety disorders.ConclusionsVenlafaxine ER seems to be effective and well tolerated in the short-term treatment of panic disorder.

Safety monitoring and successful blinding are important features of randomized, blinded clinical trials. We report chamber- and protocol-related adverse events (AEs) for participants enrolled in two randomized, double-blind clinical trials of hyperbaric oxygen (HBO2) for persistent post-concussive symptoms clinicaltrials.gov identifiers NCT01306968, HOPPS, and NCT01611194, BIMA), as well as the success of maintaining the blind with a low-pressure sham control arm. In both studies, participants were randomized to receive HBO2 (1.5 atmospheres absolute, >99% oxygen) or sham chamber sessions (1.2 atmospheres absolute, room air). In 143 participants undergoing 4,245 chamber sessions, chamber-related adverse events were rare (1.1% in the HOPPS study, 2.2% in the BIMA study). Minor, non-limiting barotrauma was the most frequently reported. Rarely, some participants experienced headache with chamber sessions. No serious adverse events were associated with chamber sessions. An allocation questionnaire completed after intervention revealed that the sham control arm adequately protected the blind in both trials. Participants based allocation assumptions on symptom improvement or lack of symptom improvement and could not discern intervention arm by pressure, smell, taste, or gas flow.

IntroductionUp to 50% of patients with OCD have failed to respond in SSRI trials, so looking for pharmacological alternatives in treatment of obsessive compulsive disorder (OCD) seems necessary.ObjectivesSurveying duloxetine augmentation in treatment of resistant OCD.AimsStudy the effects of serotonin-norepinephrine enhancers for treatment of OCD.MethodsThis augmentation trial was designed as an 8-week randomized controlled, double blind study. Forty-six patients suffering from OCD who had failed to respond to at least 12 weeks of treatment with a selective serotonin reuptake inhibitor (fluoxetine, citalopram or fluvoxamine) were randomly allocated to receive duloxetine or sertraline plus their current anti OCD treatment. Yale-Brown Obsessive Compulsive Scale (Y-BOCS) was the primary outcome measure.ResultsForty-six patients (24 of 30 in duloxetine group and 22 of 27 in sertraline group) completed the trial. Both groups showed improvement over the 8-week study period (mean Y-BOCS total score at week 8 as compared with baseline: P < 0.001 and P < 0.001) without significant difference (P = 0.861). Those receiving duloxetine plus their initial medications experienced a mean decrease of 33.0% in Y-BOCS score and the patients with sertraline added to their initial medication experienced a mean decrease of 34.5% in Y-BOCS.ConclusionsOur double blind controlled clinical trial showed duloxetine to be as effective as sertraline in reducing obsessive and compulsive symptoms in resistant OCD patients. However, it needs to be noted that our study is preliminary and larger double blind placebo controlled studies are necessary to confirm the results.Disclosure of interestThe authors have not supplied their declaration of competing interest.

AbstractLittle is known about long-term effects of homeopathic treatment. Following a double-blind, placebo controlled trial of classical homeopathy in chronic headaches, we conducted a 1-year observational study of 18 patients following the double-blind phase, and a complete follow-up study of all trial participants. Eighteen patients received free treatment for daily diary data (frequency, intensity, duration of headaches) over the course of 1 y. All patients enrolled in the double-blind study were sent a 6-week headache diary, a follow-up questionnaire, a personality inventory and a complaint list. Eighty-seven, of the original 98 patients enrolled returned questionnaires, 81 returned diaries. There was no additional change from the end of the trial to the one-year follow-up. The improvement seen at the end of the 12-week trial was stable after 1 y. No differential effects according to treatment after the trial could be seen. Patients with no treatment following the trial had the most improvement after 1 y. Five of 18 patients can be counted responders according to ARIMA analysis of single-case time-series. Patients with double diagnoses and longer treatment duration tended to have clearer improvements than the rest of the patients. Approximately 30% of patients in homeopathic treatment will benefit after 1 y of treatment. There is no indication of a specific, or of a delayed effect of homeopathy.
