In this randomized, open-label, 8-week comparative study, the efficacy and safety of venlafaxine and fluoxetine were assessed in outpatients with major depression. One hundred forty-five patients were assigned to receive venlafaxine 37.5 mg twice daily or fluoxetine 20 mg once daily. On day 15, if clinically indicated to improve patient response, the dosage could be increased at the investigator's discretion to venlafaxine 75 mg twice daily or fluoxetine 40 mg once daily. One hundred forty-five patients were evaluated for safety and 110, for efficacy. The mean age was 37 years, and 70% of the patients were female. In both treatment groups, mean scores on the Hamilton Depression Rating Scale decreased significantly between baseline (27.8, venlafaxine; 29.2, fluoxetine) and the end of the study (8.7, venlafaxine; 8.2, fluoxetine). Similarly, mean scores on the Montgomery-Asberg Depression Rating Scale decreased significantly between baseline (31.4, venlafaxine; 31.6, fluoxetine) and the end of the study (8.3, venlafaxine; 7.6, fluoxetine). In venlafaxine patients, the most common adverse events were nausea (44.3%), headache (40.0%), insomnia (31.4%), dizziness (30.0%), and dry mouth (22.9%); in fluoxetine patients, they were headache (32.0%), nausea (28.0%), insomnia (24.0%), anxiety (21.3%), sleepiness (20.0%), and generalized tremor (20.0%). The results of this study indicate that venlafaxine is effective and well tolerated for the treatment of major depression at doses of 37.5 or 75 mg twice daily and not significantly different from fluoxetine 20 or 40 mg once daily.

One hundred patients admitted to an acute hospice/palliative care unit in a U.S. teaching hospital were evaluated using a standardized data acquisition tool that assessed the presence of physical symptoms and attitudes concerning admission to such a specialty unit. Patients entering the unit between June 1995 and October 1995 completed the tool within 24 hours of admission. Symptoms reported were fatigue in 81 patients, anorexia in 70, dyspnea in 61, xerostomia in 58, cough in 52, pain in 49, confusion in 37, depression in 37, constipation in 35, nausea in 30, insomnia in 23, and vomiting in 22. Of the 59 patients and family/friends that responded to the question "How do you feel about hospice care?", 53 gave a positive response. When asked about the best aspects of the unit, the most common response related to the care the patient and family received (23 responses, 39%). We conclude that patients admitted to an acute inpatient hospice/palliative care unit have multiple symptoms and a high degree of satisfaction with the environment.

The objectives of this study were to assess the tolerability, safety, pharmacodynamics and pharmacokinetics of high-dose moclobemide in healthy subjects. Two sequential groups of six male and six female subjects (eight on active treatment, four on placebo) received for 8 days moclobemide 450 mg b.i.d. and 600 mg b.i.d., respectively. Intravenous tyramine pressor tests were conducted at baseline, at the beginning of treatment and at steady state. Oral tyramine pressor tests with 50, 100 and 150 mg tyramine were conducted under steady-state conditions. Pharmacokinetic parameters of moclobemide and two of its metabolites in plasma and urine were determined after the first and last dose of moclobemide. The incidence and intensity of adverse events was dose-dependent. The most frequently reported adverse events were insomnia, headache, dizziness and dry mouth. The i.v. tyramine pressor sensitivity during both moclobemide dosing regimens was enhanced 3 to 4-fold. Intake of tyramine 50 mg did not result in systolic blood pressure increases greater than 30 mmHg. With regard to blood pressure increases, tyramine 100 mg is still compatible with moclobemide 450 mg b.i.d. but not with 600 mg b.i.d. The clearance of moclobemide decreased by about 60% on multiple dosing, but no differences were found between both dosing regimens. The urinary excretion of the N-oxide metabolite doubled during multiple dosing. In conclusion, the maximum tolerated dose of moclobemide in healthy subjects is 600 mg b.i.d. provided the tyramine content in a meal is not higher than 50 mg.

The objective of this study was to compare the efficacy and safety of Claritin-D 24 Hour (once daily) with that of Claritin-D 12 Hour (twice daily) and placebo in the treatment of patients with seasonal allergic rhinitis (SAR). In this double-blind, placebo-controlled, multicenter study, 469 patients with moderate-to-severe SAR symptoms were treated for 2 weeks with one of the following: Claritin-D 24 Hour (a combination tablet formulation of loratadine 10 mg in the coating and pseudoephedrine sulfate 240 mg in an extended-release core), Claritin-D 12 Hour (a combination tablet formulation of loratadine 5 mg in the tablet coating and 120 mg pseudoephedrine sulfate, 60 mg in the coating and 60 mg in the core), or placebo. Claritin-D 24 Hour and Claritin-D 12 Hour were consistently superior to placebo (P < 0.01) in reducing total, nasal, and nonnasal symptom scores. Patients in the Claritin-D 24 Hour and Claritin-D 12 Hour groups also had significantly greater (P </= 0.05) relief of rhinorrhea and nasal stuffiness as compared with placebo. Insomnia was reported significantly more often (P < 0.01) in Claritin-D 12 Hour (15%) patients compared with Claritin-D 24 Hour (4%) and placebo (2%) patients. Dry mouth was reported significantly more often (P < 0.05) in Claritin-D 24 Hour (13%) and Claritin-D 12 Hour (13%) groups compared with placebo (4%). Claritin-D 24 Hour has efficacy comparable to Claritin-D 12 Hour in relieving allergic rhinitis symptoms while producing significantly less insomnia.

This multicenter study compared the efficacy and safety of citalopram and placebo in a population of moderately to severely depressed patients with melancholia. This randomized, double-blind, parallel-group study compared citalopram (flexible dose; 20-80 mg/day) with placebo in 180 psychiatric outpatients with a DSM-III diagnosis of major depression or bipolar disorder, depressed, who also met DSM-III criteria for melancholia. Following a 1-week placebo washout period, patients meeting study entry criteria were randomized to 4 weeks of double-blind treatment with either citalopram or placebo. Efficacy measures included the Hamilton Rating Scale for Depression (HAM-D), the Clinical Global Impressions (CGI) Scale, and the Zung Self-Rating Depression Scale. Patients treated with citalopram showed significantly greater improvement at endpoint than placebo patients on the HAM-D, CGI, and Zung scales. On the HAM-D, citalopram patients exhibited significantly greater improvement than placebo patients after 1 week of double-blind treatment and at all subsequent study visits. Endpoint analyses of the HAM-D subscales demonstrated that citalopram produced significant improvement of the psychomotor retardation, cognitive disturbance, sleep disturbance, and melancholia symptom clusters. Nausea, dry mouth, somnolence, dizziness, and increased sweating were reported at higher rates by citalopram-treated patients than by placebo-treated patients, but there were no significant citalopram-placebo differences in the incidence of activation (e.g., anxiety, nervousness, insomnia) or sexual dysfunction. Analysis of electrocardiograms, vital signs, and laboratory tests did not reveal any clinically significant effects of citalopram treatment. The results of this study indicate that citalopram is safe and effective in the treatment of depressed patients with melancholia, and is associated with a favorable side effect profile and a potentially rapid onset of action.

This series of studies was undertaken to assess the safety profile of sustained-release (SR) bupropion in the treatment of depressed outpatients. Adults with a diagnosis of major depression were evaluated in 1 of 3 multicenter, randomized, double-masked, parallel-group, placebo-controlled trials conducted in private-practice psychiatric outpatient clinics. Following a 1-week, single-masked, placebo lead-in period, patients received bupropion SR for 8 weeks (study 1: 150 or 300 mg/d; study 2: 100, 200, 300, or 400 mg/d; study 3: 50 to 150 or 100 to 300 mg/d). Safety assessments included monitoring adverse events, patient discontinuation rates, changes in weight, vital signs, and clinical laboratory test results. Across studies, the most frequently reported adverse events were headache, dry mouth, and nausea. The incidence of adverse events was similar (< or =5% difference) between the bupropion SR and placebo groups, with the exception of dry mouth (bupropion SR, 16%; placebo, 7%). Dry mouth, nausea, and insomnia occurred significantly more often in bupropion SR-treated patients than in patients who received placebo (P<0.05). Nearly all (94% to 99%) adverse events reported in these studies were mild or moderate. Less than 10% of patients in either group discontinued treatment prematurely because of adverse events, and no deaths or serious drug-related adverse events were reported. Sexual dysfunction was reported as an adverse event by <1% of patients in either group. Bupropion SR was associated with dose-related weight loss in all 3 studies. No consistent patterns of change were observed in vital signs or in the results of clinical laboratory tests. Data from these 3 clinical trials demonstrate the favorable safety profile of bupropion SR in the treatment of depressed outpatients.

The primary objectives of this multicenter study were to determine the efficacy and safety of moclobemide, a selective reversible inhibitor of monoamino oxidase A, as drug treatment in DSM-III-R panic disorder with and without agoraphobia. In a comparative double-blind, randomized parallel-group design with fixed-flexible dose moclobemide 450 mg per day was compared to clomipramine 150 mg per day, as that drug was considered standard treatment of panic disorder in Europe. 135 patients were randomized and treated for a period of eight weeks. No other treatment was given. By the end of week 8, 49% of the patients treated with moclobemide and 53% of those treated with clomipramine were seen as treatment responders since they were without panic attacks. 78% of the patients in the moclobemide and 88% in the clomipramine group were considered responders according to clinical global impression of change. No significant differences were found between the two treatments at week 8. Adverse events were observed with significantly higher frequency among patients treated with clomipramine, particularly due to anticholinergic side effects. Close to 20% of those treated with moclobemide experienced headache, dizziness, nausea, insomnia, or dry mouth, but other adverse effects were infrequent. In conclusion, moclobemide in a dose of 450 mg per day seems to be a good drug alternative for treatment of panic disorder with and without agoraphobia.

Sexual dysfunction, a frequently reported side effect of many antidepressants, may result in patient dissatisfaction and noncompliance with treatment regimens. This paper describes the results of the first placebo-controlled comparison of the efficacy, safety, and effects on sexual functioning of sustained-release bupropion (bupropion SR) and the selective serotonin reuptake inhibitor sertraline. This randomized, double-masked, double-dummy, parallel-group, multicenter trial enrolled 360 patients with moderate-to-severe recurrent major depression. Patients were treated with bupropion SR 150 to 400 mg/d, sertraline 50 to 200 mg/d, or placebo for up to 8 weeks. Patients' depression and sexual functioning were assessed at weekly or biweekly clinic visits; safety was assessed by regular monitoring of adverse events, vital signs, and body weight. Treatment groups were similar at baseline in terms of age, sex, and race, and most patients had a diagnosis of moderate uncomplicated depression. Patients treated with bupropion SR or sertraline showed similar improvements on all efficacy measures; both active treatments were superior to placebo in improving scores on all rating scales for depression at various time points. Significantly more patients treated with sertraline experienced orgasmic dysfunction throughout the study than did patients treated with bupropion SR or placebo (P < 0.001). Headache was the most frequently reported adverse event in all 3 treatment groups and occurred with similar frequency in each group (30% to 40%). Nausea (31%), diarrhea (26%), insomnia (18%), and somnolence (17%) occurred in significantly more patients in the sertraline group than in the bupropion SR group (18%, 7%, 13%, and 3%, respectively) and the placebo group (10%, 11%, 4%, and 6%, respectively). Dry mouth occurred more frequently with bupropion SR (19%) than with sertraline (14%) or placebo (12%), although the differences were not significant. Changes in vital signs were similar in all groups. Similar (small, but not statistically significant) decreases in mean body weight were seen in both the bupropion SR (-1.06 kg) and sertraline (-0.79 kg) groups, whereas the placebo group experienced a minor increase (0.21 kg). Although bupropion SR and sertraline were similarly well tolerated and effective in the treatment of depression, sertraline treatment was more often associated with sexual dysfunction and certain other adverse events compared with bupropion SR and placebo. Therefore, bupropion SR may be an appropriate choice as an antidepressant for the treatment of sexually active patients.

Although costly polysomnography (PSG) is not routinely performed with people with insomnia, it may be more necessary with recruited older adults with insomnia because this population may pose a greater risk of veiled sleep disorders compared with younger age groups and with referred samples. The present PSG screening of a recruited sample of older adults with insomnia found a 29%-43% rate of undiagnosed sleep apnea (SA), depending on whether an apnea-hypopnea index of 15 or 5 was used, after interviews had already screened out obvious cases of SA. Also, PSGs revealed a 4% rate of occult periodic limb movements. A discriminant analysis identified overweight men reporting dry mouth at highest risk for occult SA, with an apnea-versus-insomnia classification success rate of 78%. Using PSG evaluations in research on insomnia in recruited older adults is requisite to preclude substantial representation of occult SA.

This was an 8-week, multicenter, open-label study of the efficacy and tolerability of venlafaxine in patients with treatment-resistant depression conducted in Canada. Inpatients or outpatients aged 18 to 70 years with major depression were eligible if they had a 21-item Hamilton Rating Scale for Depression (HAM-D-21) score of 2 > or = 18 and a documented history of unsatisfactory improvement after a minimum of 8 weeks of treatment with an adequate dose of an antidepressant. Treatment with venlafaxine was started at 37.5 mg twice daily, and the dose could be titrated upward to a maximum of 375 mg/day during the first 4 weeks on the basis of the investigator's assessment of clinical response and tolerability. Of the 159 patients enrolled, 152 were evaluable for efficacy. The mean daily venlafaxine dose was 260 mg/day. The mean HAM-D-21 score decreased by 52%, and the mean Montgomery-Asberg Depression Rating Scale score decreased by 50% from baseline to day 56. A response (50% improvement from baseline) was achieved by 58% of patients on the HAM-D-21, and a remission (> or = 75% improvement in the HAM-D-21) was observed in 28% at day 56. By day 56, 88% of patients had improved from baseline on the Clinical Global Impression Improvement scale. Only 8% of the patients discontinued for adverse events. The most common adverse events were headache, insomnia, nausea, constipation, diaphoresis, and xerostomia. In conclusion, these results suggest that venlafaxine is effective and well tolerated for the management of patients with treatment-resistant major depression.
