In a double-blind trial, comprising 96 depressed patients, citalopram was compared with maprotiline. The trial period was 6 weeks with ratings (MADRS, CGI) and side effects recordings taking place at Weeks 0, 1, 2, 4, and 6. Both drugs were administered as a single evening dose, 40 or 60 mg for citalopram, and 75 or 150 mg for maprotiline. MADRS total scores and CGI scores showed a highly significant reduction in both groups with no significant difference between them, whether the groups were considered as a whole or whether they were subdivided into endogenously/non-endogenously depressed or melancholic/non-melancholic patients. Side effects were not significantly different, but the maprotiline group showed more anticholinergic side effects, whereas the citalopram group showed more nausea, increased sweating and headache. Two patients on maprotiline were withdrawn because of side effects (hypotension and somnolence in the one case; tremor and insomnia in the other). One patient in each group was withdrawn because of increased transaminases, the citalopram-treated patient having increased values, however, already at baseline. Apart from this, no cardiovascular side effects and no pathological laboratory values related to treatment were observed. The authors conclude that citalopram is a safe antidepressant drug and as effective as maprotiline.

In an open study, 42 depressive patients (according to DSM-III-R) were administered paroxetine at mean minimal and maximum doses of 21 and 48 mg once daily in the morning. Treatment resulted in complete remission as defined by Serejsky in 57%, and 55% of patients were rated, according to CGI, as improved. Global HAMD and FKD scores significantly dropped compared to baseline values and responders and non-responders differed significantly as early as seven days of treatment, although the onset of the antidepressive effect was not clinically apparent before 2 weeks of treatment. Significant reductions were seen in all items except paranoidity and weight loss and hypochondria using the FKD scale. A substantial reduction in suicidal ideation and tendencies was also noted in the group of non-responders, a finding supporting a non-specific anti-suicidal effect of paroxetine, which was therapeutically significantly more successful in women than in men. Side effects occurring in 10% and more percent of treated subjects included fatiguability, sweating, tremor, dry mouth, obstipation and nausea.

State-anxiety has been defined as a transitory emotional response involving unpleasant feelings of tension and apprehensive thoughts. Trait-anxiety, on the other hand, has been defined as a personality trait referring to individual differences in the likelihood that a person would experience state anxiety in a stressful situation. The aim of the present study was to assess trait and state-anxiety in a population of patients consulting physicians for anxious complaints. Thus, patients who stopped the benzodiazepine (BZD) treatment after three months and those who continued it for six months were compared. Included patients were evaluated at inclusion (D0), after three months (M3) and after six months (M6). The investigator filled the Covi anxiety scale, the Raskin depression scale and a CGI; patients were asked to fill the Spielberger state/trait-anxiety questionnaire. 1,112 patients have been included, 48% considered their anxiety as chronic, 50% said the evolution was progressive, 87% considered it resulting of a trigger factor, 69% received a benzodiazepine (BZD) treatment. At D0: Covi anxiety score was 5.3 +/- 2.3 points, STAI I (state-anxiety) score was 57.4 +/- 12.2 points and STAI II (trait-anxiety) score was 52.7 +/- 10.2 points. At M3, all scores decreased, and 85% were considered as ameliorated, but differences were significant (p = 0.0001) at M6. When comparing at D0 patients who stopped BZD treatment at M3 and those who continued it, some differences appeared. In fact subjects who stopped the treatment had lower score at the STAI II, presented significantly less flushes (p = 0.01), less tremor (p = 0.04) and less feverishness (p = 0.05). Their score at Covi tended to be lower (p = 0.11). The severity of the disease, evaluated with the CGI, was also lower for the patients who stopped the BZD treatment. The trait-anxiety appeared as a good predictor of the efficacy of the BZD treatment. In fact, the trait-anxiety refers to a tendency to be anxious and higher anxiety necessitates longer treatment. The treatment response was less important in the patients who continued the treatment at M3, indicating the presence of residual anxiety in these patients.

The objectives of this study is to examine the effects of neuromuscular therapy (NMT) on motor and nonmotor symptoms in Parkinson's disease (PD). Thirty-six subjects with PD were randomly assigned to NMT or music relaxation (MR, or active control). Subjects received treatment twice a week for 4 weeks. Testing was conducted at baseline, after final treatment, and 8 days after final treatment. Primary outcome measures were the Motor subscale of the United Parkinson Disease Rating Scale (UPDRS) and the Clinical Global Impression scale (CGI-Change). Secondary outcome measures included a PD-specific quality of life scale (PDQ-39), quantitative measures of motor function, and severity scales for anxiety and depression symptoms. NMT resulted in a significant and sustained improvement in the Motor subscale of the UPDRS (P < or = 0.0001), most notable in the tremor scores. Also improved 1 week after the last treatment were the CGI scores (P = 0.007) and the finger-tapping speed (P = 0.001). The MR active control group had a slight improvement in tremor but evidenced no other change in motor function. Both groups exhibited a modest improvement in quality of life immediately after the last treatment. This effect was sustained for 8 days only in the MR group. In the nonmotor domains, the MR group evidenced improvements in mood (P = 0.001) and anxiety (P = 0.002), whereas NMT had no effect on mood (P = 0.09), and its initial effect on anxiety (P = 0.0009) dissipated after 8 days (P = 0.40). Group differences for UPDRS motor score and patient CGI-Change were superior in the NMT compared to the MR group. There was no group difference in PDQ-39 scores or in nonmotor measures. The findings suggest that NMT can improve motor and selected nonmotor symptoms in PD and that this effect is more durable for the motor symptoms. The results of this pilot study warrant larger controlled studies to examine dose range, durability, and mechanisms of NMT in PD function.

Medical therapy for essential tremor (ET), a common movement disorder, is often inadequate. We performed a double-blind placebo-controlled randomized trial to evaluate the efficacy and tolerability of zonisamide (ZNS), an antiepileptic agent, in treating ET. Twenty patients (mean age, 60 +/- 15 years) with ET were randomized to receive ZNS or placebo. ZNS was initiated at a dosage of 100 mg/day and escalated to 200 mg/day at day 14. Patients were evaluated by accelerometry and the Fahn-Tolosa-Marin (FTM) rating scale at baseline and days 14 and 28, as well as the Clinical Global Impression (CGI-C) scale at day 28. At endpoint, subjects assigned to ZNS were taking a mean dosage of 160 +/- 50 mg/day. There were no significant improvements in the FTM total score or its subsections. Tremor amplitude as assessed by accelerometry significantly improved in the ZNS group compared to the placebo group at endpoint relative to baseline (-0.50 +/- 0.72 vs. 0.30 +/- 0.79 m/s(2); P = 0.03). On the CGI-C, 60% (n = 6) of patients in the ZNS group felt that their tremor was unchanged, while the remaining patients felt that their tremor was "minimally improved." Thirty percent (n = 3) of patients taking ZNS discontinued the study due to side effects (fatigue, headache, paresthesias) while taking 100 mg per day. ZNS did not provide significant improvements in clinical rating scales at study endpoint compared to placebo and was only modestly well tolerated. ZNS was effective in reducing tremor amplitude as measured by accelerometry.

This research compared the long-term efficacy and safety of iloperidone with those of haloperidol in individuals with schizophrenia. Data were pooled from 3 prospective multicenter studies, each with 6-week stabilization followed by 46-week double-blind maintenance phases. Patients were randomized to iloperidone 4 to 16 mg/d or haloperidol 5 to 20 mg/d. Patients included in this analysis completed the initial 6-week phase with at least 20% reduction in Positive and Negative Syndrome Scale (PANSS) total score at weeks 4 and 6, had 7-item Clinical Global Impressions of Change (CGI-C) scores less than 4, received 1 or more doses of long-term phase medication, and had 1 or more efficacy/safety assessments during the long-term phase. The primary efficacy variable was time to relapse, defined as a 25% or more increase in PANSS total score, including at least a 10-point change; discontinuation because of lack of efficacy; aggravated psychosis with hospitalization; or 2-point increase in the 7-item CGI-C after week 6. Of 1644 patients randomized and 1326 completing the 6-week phase, 473 (iloperidone, n = 359; haloperidol, n = 114) were included in the long-term efficacy analysis, and 489 (iloperidone, n = 371; haloperidol, n = 118) in the safety analysis. Iloperidone was equivalent to haloperidol in time to relapse. The most common adverse events were insomnia (18.1%), anxiety (10.8%), and schizophrenia aggravated (8.9%) with iloperidone, and insomnia (16.9%), akathisia (14.4%), tremor (12.7%), and muscle rigidity (12.7%) with haloperidol. The Extrapyramidal Symptoms Rating Scale scores improved with iloperidone and worsened with haloperidol. Metabolic changes were minimal for both groups. Mean changes in Fridericia's QT interval correction were 10.3 msec (iloperidone) and 9.4 msec (haloperidol) at end point. Iloperidone demonstrated long-term efficacy equivalent to haloperidol and a favorable long-term safety profile, potentially making this agent a suitable option as maintenance therapy for schizophrenia.

To determine the efficacy and tolerability of olanzapine/fluoxetine combination (OFC) compared with lamotrigine (Lam) for long-term treatment of bipolar I depression, this 25-wk, randomized, double-blind study compared OFC (6/25, 6/50, 12/25, or 12/50 mg/d, n=205) with Lam titrated to 200 mg/d (n=205) in patients with bipolar I disorder, depressed. A protocol-specified analysis of 7-wk outcomes was previously reported. Outcome measures included Clinical Global Impressions-Severity of Illness (CGI-S) (primary), Montgomery-Asberg Depression Rating Scale (MADRS), and Young Mania Rating Scale (YMRS) scores. OFC-treated patients had significantly greater improvement than Lam-treated patients over 25 wk on CGI-S (p=0.008), MADRS (p=0.005), and YMRS (p<0.001) scores, and from baseline across visits from week 5 (titration complete) to the end of the study on CGI-S (p=0.043), MADRS (p=0.017), and YMRS (p=0.001) scores. Of patients in remission after the 7-wk acute phase, there was no significant difference between treatment groups in the incidence of relapse (MADRS >15, p=0.528). Rate of treatment-emergent mania was not significantly different by treatment (p=0.401). OFC-treated patients had more frequent (p<0.05) somnolence, increased appetite, dry mouth, sedation, weight gain, and tremor; Lam-treated patients had more frequent insomnia. There was a significant difference in incidence of treatment-emergent cholesterol > or = 240 (p<0.001) and in weight gain of > or = 7% (p<0.001) in favour of the Lam group. Patients with bipolar I depression had significantly greater symptom improvement over 25 wk on OFC compared with Lam. There was no treatment difference in incidence of relapse. OFC-treated patients had more treatment-emergent adverse events and greater incidence of weight gain and hypercholesterolaemia.

Bupropion, a noradrenaline/dopamine reuptake inhibitor, and venlafaxine, a serotonin/noradrenaline reuptake inhibitor, are both established antidepressants with proven efficacy in randomized controlled clinical trials. The objective of this double-blind, randomized, placebo- and active-controlled, eight-week, flexible-dose study was to evaluate the efficacy and tolerability of the once-daily extended-release formulations of these two antidepressants compared with placebo. Patients with major depressive disorder were randomized to once-daily treatment with bupropion XR 150 mg (n = 204), the extended-release formulation of venlafaxine (venlafaxine XR) 75 mg (n = 198) or placebo (n = 189) during weeks 1 to 4, with the option to double the dose at week 5 if response was inadequate. In this study, bupropion XR did not demonstrate statistically significant evidence of greater improvement from baseline compared with placebo on week 8 Montgomery Asberg Depression Rating scale scores (primary endpoint) or on secondary endpoints including CGI, HAM-A and responder and remitter analyses. Descriptive statistics for venlafaxine XR indicated separation versus placebo on MADRS total scores at week 8 and other intermediate time points, and on other endpoints including CGI, HAM-A and responder and remitter analyses. Both active treatments elicited improvement on the Sheehan Disability Scale and its subscales and were generally well tolerated at the doses studied. Rates of nausea, dry mouth, dizziness, hyperhidrosis, insomnia, constipation, tremor, anorexia and male sexual dysfunction were elevated in the venlafaxine XR group, consistent with its mixed serotonergic/noradrenergic mechanism. Rates of dry mouth, insomnia and hyperhidrosis were elevated in the bupropion XR group, consistent with its catecholaminergic mechanism.

One hundred and twenty-five patients (49 men and 76 women, mean age 38,0+/-12,5 years) were randomized in two groups. One group (64 patients) was treated with valproate sodium and another group (61 patients) received lithium carbonate. Monotherapy was administered with the mean dose of valproate 20 mg/kg/day (serum valproate concentration between 70 and 125 ?g/ml) and the mean dose of lithium 800 mg/day (between 600 and 900 mg/day; serum lithium concentration 0,8-1,2 mmol/L) during 12 weeks. Clinical effectiveness was assessed using YMRS, CGI-BP and MADRS at 0, 5th, 10th, 21st , 84th days of treatment. The number of responders (50% reduction in YMRS scores) was 51,7% (30 patients) in lithium group and 56,7% (34 patients) in valproate group by the 21st day (p=0,59).The mean reduction in YMRS scores was 11,6 in patients treated with lithium and 12,3 in patients treated with valproate. By the 84th day (LOCF), the number of responders reached 85% (51 patients) in lithium group and 90,3% (56 patients) in valproate group (p=0,37). The mean reduction in YMRS scores was 19,4 in patients treated with lithium and 19,6 in patients treated with valproate. The average reduction in MADRS scores was -1,4 (p=0,08) and -2,2 (p=0,001) in lithium group; -1,6 (p=0,002) and -1,4 (p=0,019) in valproate group on the 21st and 84th days. Adverse effects were observed in 8 (13,1%) patients who received lithium and 3 patients (4,7%) who received valproate (p=0,12). The most common of them were tremor, nausea, dry mouth. There were no clinically significant abnormalities in laboratory values, vital functions and EEG. In conclusion, the results demonstrated equal therapeutic efficacy, tolerability and safety of valproate and lithium in the treatment of manic episodes in patients with bipolar disorder.

To accomplish therapeutic goal it is necessary to adjust the dose of medication to be right for every single patient. This procedure of dose adjustment is individualized dose regimen. First of all, pharmacokinetic aspects should be revised, including parameters such as resorption, distribution, metabolism and secretion of drug. For these purposes, the authors developed and clinically assessed the modified Bayesian method supported by original basic computer program. The aim of research was to compare frequency of adverse events in cases of individualized and empiric dose regimens of amitriptyline in the treatment of major depressive episode. Sixty subjects (32- 65 years old), with major depressive disorder (International Classification of Disease, 10th revision), were randomly assigned and single- blinded to take individualized (experimental group, n=30) or empiric (control group, n=30) doses of amitriptyline for 8 weeks. CGI scale and originally designed questionnaire were used for adverse events assessment. In experimental group, 69 complaints on nine different types of adverse effects were recorded during eight-week treatment period. Severe adverse events, such as confusion or arrhythmia, were not registered in this subgroup. In control group, 111 complaints on twelve different types of adverse effects were recorded. Most common were anticholinergic effects, but during the third and fourth week from baseline, some severe adverse events were observed: tremor (16%), fatigue (16%), in one of the subjects confusion occurred and arrhythmia in another. Analyzing of the results according to CGI scale for adverse events showed that, during the treatment period, adverse events were less frequent in experimental group. This was particularly obvious in the first four weeks of treatment, when statistically significant difference (p<0.05) was observed.
