The efficacy and tolerability of the selective 5-HT reuptake inhibitor fluvoxamine were compared with the tricyclic dothiepin in 52 elderly (age greater than 64 years) hospital patients in a multi-centre double-blind randomised trial. Patients met DSM-III criteria for 'major depressive episode' and scored greater than 29 on the Montgomery Asberg Depression Rating Scale (MADRS) after a one-week placebo baseline. Active treatment was for six weeks. The dosage of both drugs was 50 mg nocte for three days, 100 mg nocte for the remainder of the first week, thereafter increasing to a maximum of 200 mg/day according to response/tolerance. MADRS scores improved by 63.5% with fluvoxamine and 60.0% with dothiepin; there were no significant differences between treatments at any assessment. Nausea, dizziness, headache, somnolence and constipation in both groups, plus dry mouth and asthenia in the dothiepin group were more frequent than single reports. Two patients in each group discontinued treatment owing to unwanted effects. There were no clinically significant changes in haematological, biochemical or cardiovascular parameters.

A double-blind, placebo- and amitriptyline-controlled comparison study was performed to evaluate the antidepressant efficacy of sertraline, a specific serotonin uptake inhibitor. Patients with DSM-III-defined major depression randomly received either sertraline (N = 149), amitriptyline (N = 149), or placebo (N = 150) once daily for the 8-week study period. The mean final daily medication dose for the all-patients group was 145 mg and 104 mg for the sertraline- and amitriptyline-treatment groups, respectively. As measured by the Hamilton Rating Scale for Depression and the Clinical Global Impressions Scale, both the sertraline and amitriptyline treatment groups showed a significantly greater improvement from baseline (p less than or equal to .001) than the placebo group. The sertraline group had a higher proportion of gastrointestinal complaints and male sexual dysfunction than either the amitriptyline or the placebo group. The amitriptyline group showed a higher proportion of anticholinergic and sedative side effects and dizziness compared with patients who received either sertraline or placebo.

CO2 inhalation has been reported to induce panic attacks in panic disorder patients. State anxiety, somatic symptoms of anxiety, physiological changes, and cerebral blood flow (CBF) were monitored in panic disorder patients before and after intravenous injections of 1 g of acetazolamide (13 patients) and saline (10 patients), given under double-blind conditions. In spite of significant hypercarbia, as evidenced by increased CBF in the former group, only one subject reported panic and even that attack did not meet DSM-III-R criteria. There was only one significant difference between the drug and placebo groups; the acetazolamide group experienced significantly more dizziness.

Sixty (60) out-patients with DSM III generalized anxiety disorder were treated after a 1-week placebo washout in a 4-week double-blind study with buspirone, diazepam and placebo; after which they were withdrawn abruptly from medication or assigned to a 2-week period of placebo. The HAM-A score was significantly lower in the diazepam group at week 2 (p less than .02) and the buspirone group at week 3 (p less than .04) as compared to the placebo group. A similar pattern was evident in the female group, but not in the male group. Dizziness was the most prominent adverse effect in the buspirone group, whereas the diazepam group had more adverse effects including sedation, fatigue, dizziness and impaired concentration. Withdrawal symptoms were more evident in the diazepam group than the buspirone group.

Psychiatric assessments were made of patients with psychogenic dizziness (N = 17) and severe tinnitus (N = 24) using the Structured Clinical Interview for DSM-III-R (SCID). The psychogenic dizziness group had a high prevalence of psychiatric disorders (100%), the majority being anxiety disorders (94%), particularly diagnoses in the panic-agoraphobic cluster (76%). The severe tinnitus group had a lower prevalence of psychiatric disorders (63%) with a predominance of mood disorders (46%). Those tinnitus patients with no hearing loss tended to have more diagnoses per patient and more anxiety disorders than those with hearing loss. Although this was not a random sampling of these patients populations, the results are of sufficient magnitude to warrant further studies. The implications of the results are discussed in terms of treatment and future research.

In 72 outpatients with DSM-III major depressive episode, adinazolam was superior to placebo in all measurements. Significantly more adinazolam-treated subjects (N = 36) than placebo subjects (N = 36) completed the study (67% vs. 19%), were rated "much" or "very much" improved (78% vs. 19%), and had a "moderate" or "marked" therapeutic effect of the drug (67% vs. 19%). The total Hamilton Rating Scale for Depression score decreased by 50% or more in 61% of the adinazolam group and in 17% of the placebo group; 72% of the adinazolam group reported that they felt "moderately," "much," or "very much" improved compared with 17% of the placebo group. The adinazolam group reported significantly more drowsiness and lightheadedness, dizziness, or faintness; the severity of these side effects decreased with time. No significant anticholinergic effects were observed.

Moclobemide (Ro 11-1163), a benzamide derivative, is a MAO-inhibitor which selectively and reversibly inhibits monoamine oxidase type A. Thirty-eight patients with episodic, chronic and atypical depressive disorder (DSM-III) were equally randomized to 6 weeks' treatment with either three daily doses of 100 mg moclobemide or 50 mg clomipramine. Both treatment groups improved with time as assessed weekly by the Hamilton Depression Scale and the Clinician's Overall Assessment of Depression State, and there was no interaction between treatment and time. Anticholinergic complaints, tremor and dizziness occurred more frequently on clomipramine, and they were longer lasting and more severe. Because of its low toxicity, good tolerance, its selectivity and reversibility moclobemide may be a better alternative than the older monoamine oxidase inhibitors.

Seven hundred twelve patients meeting DSM-III-R criteria for major depression and recommended for antidepressant treatment were treated with moclobemide as outpatients (88%) or inpatients in ordinary psychiatric practices. These differ from the highly selected patients usually studied in antidepressant research, without comorbidity, or coprescription and treated in special clinics. Sixty-five percent were women, with a mean age of 45 (+/- 13.6) years, and 88% were outpatients. Eighty-eight percent had preexisting depression. Eight percent had prior manic episodes. Previous antidepressant treatment for this episode had been received by 69%, with the most common reasons for change to moclobemide being inadequate response (66%) and poor tolerability (20%). The modal final dose was 450 mg. Regarding tolerability, 52% did not report adverse events. The most common adverse events were insomnia or stimulation (13%), nausea (11%), headache or migraine (11%), dizziness or disorientation (6%), sedation or drowsiness (5%), agitation or nervousness (3%), and diarrhea (3%). Only 10% of adverse events were severe, and 83% lasted less than 2 weeks. There was no difference when moclobemide followed fluoxetine use. Most adverse events did not significantly differ from the frequencies reported in double-blind placebo-controlled studies. Concomitant medications from all major drug groups were taken by 520 patients (73%), with no adverse interactions. Moclobemide overdose resulted in an uneventful recovery, whereas mixed overdoses caused no problems other than those attributable to coprescribed medication. On physician clinical global impression, 65% were moderately improved or better after 8 weeks.(ABSTRACT TRUNCATED AT 250 WORDS)

An 8-week open-label study of nefazodone treatment of DSM-III-R major depressive episode (MDE) (n = 18) is reported. Nine of 15 individuals completing treatment also met DSM-III-R criteria for obsessive compulsive disorder (OCD). A significant reduction in depressive and anxiety symptoms was observed in treatment completers; no differences were found between those patients with and those without comorbid OCD. A trend toward an antiobsessional response was seen among those with OCD. The degree of anxiolytic response was found to be significantly correlated with the degree of antidepressant response. Nefazodone was well tolerated in most patients, with dizziness, joint pain, dry mouth, and sedation as the most commonly reported adverse events.

Medical patients' (75 with chronic fatigue complaints, 61 with dizziness, and 88 with disabling tinnitus; N = 224) current and past psychiatric diagnoses and personality characteristics were assessed to determine if they could independently explain the number of medically unexplained physical symptoms that the patients had experienced. Cloninger's Tridimensional Personality Questionnaire (TPQ) and the Diagnostic Interview Schedule based on DSM-III-R were used to assess the personality and psychiatric diagnoses, respectively. The results revealed that the number of lifetime medically unexplained symptoms were significantly, independently, and positively related to increasing numbers of current and past anxiety and depressive disorders and to the harm avoidance dimension of the TPQ. In a second analysis, the "worry/pessimism" and "impulsiveness" subscales were positively related to the number of medically unexplained symptoms. The results suggest that somatization is associated with current and past history of psychiatric illnesses and harm avoidance in this sample of medical patients.
