The aim of this study was to assess the specific influence of poststroke depression (PSD) on both basal functional status and rehabilitation results. We performed a case-control study in 290 stroke inpatients, matched for age (+/-1 year) and onset admission interval (+/-3 days) and divided in two groups according to the presence (PSD+) or absence (PSD-) of PSD. All PSD+ patients were treated with antidepressants (AD), mainly with fluoxetine. PSD+ patients, despite similar severity of stroke, showed greater disability in coping with activities of daily living (ADL) on admission and greater disability both in ADL and mobility at discharge than PSD- patients. Although both groups exhibited similar average functional improvement during rehabilitation, PSD- patients were nearly twice as likely to show excellent recovery both on ADL and mobility as PSD+ patients (OR = 1.95, 95% CI = 1.01-3.75 and OR = 2.23, 95% CI = 1.14-4.35, respectively). All AD drugs improved depressive symptoms. Few relevant side effects were observed: fluoxetine was discontinued in 2 patients because of insomnia and in 2 patients because of nausea; paroxetine was stopped in 1 patient because of nausea and dry mouth. Our results confirm the unfavorable influence of PSD on functional outcome, despite pharmacological treatment.

At present only two drugs are approved for long-term treatment of obesity. Sibutramine inhibits the reuptake of serotonin and norepinephrine. In clinical trials it produces a dose-dependent 5-10% decrease in body weight. Its side effects include dry mouth, insomnia, asthenia, and constipation. In addition, sibutramine produces a small increase in blood pressure and pulse that is a contraindication to the use of this drug in some individuals with heart disease. Xenical is the other drug approved for long-term use in the treatment of obesity. It works by blocking lipase and thus increasing the fecal loss of triglyceride. One valuable consequence of this mechanism of action is the reduction of serum cholesterol that averages about 5% more than can be accounted for by weight loss alone. In clinical trials it produces a 5-10% loss of weight. Its side effects are entirely due to undigested fat in the intestine that can lead to increased frequency and change in the character of stools. It can also lower fat-soluble vitamins. The ingestion of a vitamin supplement before bedtime is a reasonable treatment strategy. The effect on weight loss during long-term trials with these two drugs is shown in Figs 7 and 8 above. Also in this figure is data on phentermine used in trials of six months or more. Although there were differences in mean weight losses with these drugs, when the placebo effect was taken into account they all had a surprisingly similar magnitude of weight loss.

Cetirizine is the carboxylated metabolite of hydroxyzine, and has high specific affinity for histamine H(1) receptors. Pseudoephedrine is a sympathomimetic drug that acts directly on alpha-adrenergic receptors. black triangle Cetirizine/pseudoephedrine 5/120 mg twice daily was significantly more effective than intranasal budesonide 100 microg or placebo at improving nasal obstruction, nasal patency and reducing the volume of nasal secretion, and was significantly more effective than intranasal xylometazoline 0.1% with respect to nasal secretion, during house dust mite faeces challenge in three randomised, cross- over studies among volunteers with seasonal or perennial rhinitis. The onset of action of cetirizine/pseudoephedrine was reported to be approximately 30 minutes. black triangle The bioavailability of cetirizine and pseudoephedrine is similar after administration of cetirizine/pseudoephedrine 5/120 mg bilayer tablets or coadministration of cetirizine 5 mg tablets plus pseudoephedrine sustained-release (SR) 120 mg caplets. black triangle Cetirizine 5mg plus pseudoephedrine SR 120 mg twice daily for 2 to 3 weeks was significantly more effective than each drug given alone at reducing mean total symptom scores for seasonal or perennial allergic rhinitis in two randomised, double-blind, multicentre trials. In both studies, the mean proportion of days during which the five measured symptoms (nasal obstruction, sneezing, rhinorrhoea, nasal pruritus and ocular pruritus) were absent or mild was significantly greater in recipients of the cetirizine plus pseudoephedrine SR. black triangle In one study, cetirizine 5 mg plus pseudoephedrine SR 120 mg was significantly more effective at reducing nasal obstruction than either drug alone. black triangle Cetirizine 5mg plus pseudoephedrine SR 120 mg twice daily for 2 to 3 weeks was well tolerated in patients with seasonal or perennial allergic rhinitis. The most common adverse events were dry mouth, insomnia, headache, somnolence, asthenia and nervousness.

We attempted to compare the antidepressant efficacy of milnacipran and fluvoxamine in 202 outpatients with major depression, using the 17-item Hamilton Depression Rating Scale (HDRS). Special attention was paid to the difference of responsiveness as a function of the severity of depression and individual HDRS factors. As a result, while no significant difference between the treatment groups was found overall, a positive response (50% or more decrease in total score from the baseline) was recorded significantly more often with milnacipran than fluvoxamine recipients whose baseline HDRS total score was greater than 19 points. Furthermore, there was a significant difference of response for the 'agitation' and 'insomnia' factors in favour of milnacipran. In both treatment groups, the incidence of adverse events, characteristic of tricyclic antidepressants such as dry mouth, constipation, somnolence and postural hypotension, was low. While complaints concerning the upper intestinal tract, such as epigastric distress, were predominant in the fluvoxamine group, urological complications and palpitations were reported only in the milnacipran group. In conclusion, we suggest that milnacipran is preferred to selective serotonin reuptake inhibitors for the treatment of depressed patients with agitation as well as severely depressed patients.

The effects of haloperidol, risperidone, and thioridazine on the pharmacokinetics and side-effect profile of quetiapine were investigated in 36 patients with schizophrenia, schizoaffective disorder, or bipolar disorder in a single-center, two-period, multiple-dose, open-label, randomized trial. Over a one-to two-week period, quetiapine doses were escalated to 300 mg twice daily (bid). Patients were then treated for at least 7 days at the target quetiapine dose and subsequently entered into the combination therapy period, receiving haloperidol (7.5 mg, bid), risperidone (3 mg, bid), or thioridazine (200 mg, bid) for 8.5 days (after 3 days of dose escalation). Key assessments included the pharmacokinetics of quetiapine at steady state (area under the curve within a dosing interval [AUCtSS], maximum [CmaxSS], and minimum [CminSS] observed plasma concentrations, and oral clearance [Cl/f]), as well as the UKU Side Effect Rating Scale scores and safety evaluations. Neither risperidone nor haloperidol had significant effects on quetiapine pharmacokinetics. However, thioridazine produced statistically significant changes, decreasing the least squares means values of the AUCtSS, CmaxSS, and CminSS by 40%, 47%, and 31%, respectively, and increasing Cl/f by 68%. Increases in the following adverse events were noted during coadministration: somnolence (risperidone), insomnia and dry mouth (all three coadministered therapies), and dizziness (thioridazine). UKU side effect items that became worse in >or= 25% of patients during each coadministration period included sedation and increased sleep duration. Results of laboratory tests, electrocardiograms, and vital sign measurements revealed few clinically important changes. Clinical stability can be maintained with good tolerability during the transition from quetiapine monotherapy to periods of coadministration with haloperidol, risperidone, or thioridazine. Coadministration of either haloperidol or risperidone did not have any important effects on the steady-state pharmacokinetics of quetiapine. Thioridazine significantly increased the oral clearance of quetiapine. Increased doses of quetiapine may be necessary to control psychotic symptoms when thioridazine is coadministered with quetiapine.

Sustained-release bupropion (bupropion SR) is a unique, non-nicotine smoking cessation aid that is hypothesised to act upon neurological pathways involved in nicotine dependence. Pharmacokinetic and metabolism studies reveal that bupropion SR is metabolised by multiple pathways with no single pathway predominating. When one pathway is inhibited, others are available to compensate. Therefore, only a few clinically relevant drug-drug interactions involving bupropion SR have been observed, although the potential for interactions exists, as with any extensively metabolised drug. Population pharmacokinetic/pharmacodynamic analyses of data from patients receiving daily oral doses of 100mg, 150mg, or 300mg reveal that the anti-smoking efficacy of bupropion SR is directly related to dose. The incidences of dry mouth and insomnia were directly related to bupropion plasma concentrations while the incidence of anxiety was inversely proportional to bupropion plasma concentrations. To maximise efficacy (with an acceptable safety profile), the optimal daily dose for the majority of patients is 300mg.

Sustained-release bupropion (bupropion SR) was first launched in the US in 1997 as an aid to smoking cessation and has since been launched in many other countries. Adverse events associated with the use of bupropion SR at the recommended dosage of 150mg twice daily in clinical trials most commonly included insomnia, headache, dry mouth, nausea and anxiety; insomnia and anxiety are also recognised as symptoms of nicotine withdrawal. Only insomnia and dry mouth occurred significantly more frequently with bupropion SR than with placebo. Relative to placebo, no significant changes in mean values for heart rate, blood pressure or routine laboratory parameters have been reported in smokers using bupropion SR alone in clinical trials. When bupropion SR was compared with a nicotine transdermal patch in a clinical trial, insomnia predominated in the bupropion SR group, while dream abnormalities were more common in smokers using the nicotine patch. Bupropion SR and the nicotine transdermal patch in combination can be used safely (with appropriate monitoring) as an aid to smoking cessation. Infrequent but clinically important adverse reactions to bupropion SR include seizures and hypersensitivity reactions: in controlled clinical trials of bupropion SR (300 mg/day), where smokers were carefully screened for risk factors for seizure, the incidence of both seizures and severe hypersensitivity reactions was approximately 0.1% for each event. In order to avoid a risk of seizure of greater than 0.1%, smokers should be screened for predisposing risk factors and adhere to the manufacturer's dosage recommendations (maximum daily dose of 300mg). Thus, bupropion SR is generally well tolerated, as seen by the low discontinuation rate due to an adverse event in clinical trials (6 to 12%). The most common adverse events (insomnia and dry mouth) are generally transient and often resolve quickly without therapeutic intervention; they can be managed if necessary by a reduction in bupropion dose.

Sibutramine is a combined serotonin(5-HT) and noradrenaline (NA)re-uptake inhibitor. Sibutramine works predominantly through its two pharmacologically active metabolites (i.e. primary and secondary amines) which induce marked weight loss by affecting both food intake and energy expenditure. It is able to enhance the physiological process of satiety, and to stimulate thermogenesis, increasing the efferent sympathetic activity to thermogenically active brown fat. There is a dose-related reduction in body weight in clinical trials with sibutramine, with weight loss up to 11% below baseline, which can last up to 18 months with continued treatment. When weight loss is induced with a very low calorie diet (VLCDL), patients randomized to the sibutramine treatment continued to lose weight over a 1 year period, reaching 15% below baseline, whereas the placebo-treated patients regained some weight. Sibutramine improves metabolic fitness, by decreasing the biochemical risk factors associated with obesity, such as plasma triglycerides, total cholesterol and low density lipoprotein (LDL) cholesterol, glucose and insulin, and increasing HDL-cholesterol. In controlled studies, 84% of sibutramine-treated patients reported side effects, most commonly including dry mouth, constipation and insomnia, compared with 71% of patients receiving placebo. A small increase in heart rate and blood pressure also occurs and persists for as long as treatment is continued, which, therefore, requires monitoring. Nevertheless, successful treatment of moderately hypertensive obese patients with sibutramine has been demonstrated without undue blood pressure problems and even a mean lowering of blood pressure associated with weight loss. Finally, sibutramine does not have the potential for abuse that is characteristic of amphetamine and it is indistinguishable from placebo in abuse potential studies.

10 patients underwent a trial treatment with Cappuccino coffee. All of them (8 university lecturers and 2 clerks) aged from 60 to 69 (average 63) years old, used tricyclic antidepressant because of insomnia as a monosymptomatic type of depression or insomnia as a dominant symptom in the course of depression. One, evening dose of doxepine was from 150 to 250 (average 225) mg, causing xerostomia next day usually between 9-15 o'clock. The five-minute--chewing of 15.0 g of Cappuccino coffee increased the amount of saliva, decreased xerostomia and improved the ability of speech. Beneficial effect of coffee lasted from 0.5 to 4 (average about 2) hours. To the best of our knowledge there are no publications dealing with the positive effect of coffee in xerostomia.

Escitalopram oxalate (S-citalopram, Lexapro), a selective serotonin re-uptake inhibitor antidepressant which is the S-enantiomer of citalopram, is in clinical development worldwide for the treatment of depression and anxiety disorders. Preclinical studies demonstrate that the therapeutic activity of citalopram resides in the S-isomer and that escitalopram binds with high affinity to the human serotonin transporter. Conversely, R-citalopram is approximately 30-fold less potent than escitalopram at this transporter. Escitalopram has linear pharmacokinetics, so that plasma levels increase proportionately and predictably with increased doses and its half-life of 27 - 32 h is consistent with once-daily dosing. In addition, escitalopram has negligible effects on cytochrome P450 drug-metabolising enzymes in vitro, suggesting a low potential for drug-drug interactions. The efficacy of escitalopram in patients with major depressive disorder has been demonstrated in multiple short-term, placebo-controlled clinical trials, three of which included citalopram as an active control, as well as in a 36-week study evaluating efficacy in the prevention of depression relapse. In these studies, escitalopram was shown to have robust efficacy in the treatment of depression and associated symptoms of anxiety relative to placebo. Efficacy has also been shown in treating generalised anxiety disorder, panic disorder and social anxiety disorder. Results also suggest that, at comparable doses, escitalopram demonstrates clinically relevant and statistically significant superiority to placebo treatment earlier than citalopram. Analysis of the safety database shows a low rate of discontinuation due to adverse events, and there was no statistically significant difference between escitalopram 10 mg/day and placebo in the proportion of patients who discontinued treatment early because of adverse events. The most common adverse events associated with escitalopram which occurred at a rate greater than placebo include nausea, insomnia, ejaculation disorder, diarrhoea, dry mouth and somnolence. Only nausea occurred in > 10% of escitalopram-treated patients.
