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.

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.

The present study was conducted among 719 patients enrolled by 109 doctors to evaluate the efficacy and tolerability of the combination of losartan potassium and amlodipine besylate in Indian patients with mild to moderate hypertension. Out of them 11 patients were dropped out. Of these 708 patients 643 patients received once daily dosage of the combination whereas 10 patients received 1/2 daily, 13 patients received 1 1/2 daily and 42 patients received 1 twice daily dosage of the combination. The mean SBP in the study was 172.89 +/- 19.18 mm Hg baseline. After the 10-day treatment, the mean SBP had significant reduction ie, 13.1% from basal and at the end of day 20 of the treatment, the reduction was 19.13% from the baseline which was significant. Similarly mean DBP was 105.42 +/- 10.85 mm Hg at baseline. After treatment, the mean DBP had significant reduction. After 10- day treatment, there was 12.7% reduction from the baseline and at the end of the treatment ie, after day 20, the reduction was 17.70% from basal, which was significant. Global evaluation of efficacy was done by the physicians; 93.8% of the cases had excellent to good response and 4.9% patients had fair response. Details of any adverse event reported or noted during the treatment with the combination were recorded in the appropriate section of the case record form, whether considered treatment related or not, as reported by the patients. The severity of an adverse event was graded on a 3-point scale as mild, moderate and severe. The most common side-effects reported were oedema of feet (5.08%), ankle oedema (1.98%). Remaining adverse events included some cardiovascular events such as palpitations, gastro-intestinal events such as constipation, miscellaneous events, muscular pain, weakness, generalised swelling, etc. CNS events included giddiness, headache, insomnia, etc.

Tetrabenazine (TBZ), a monoamine depleter and dopamine receptor blocker, is used to treat a variety of hyperkinetic movement disorders. The objective was to study the efficacy and tolerability of TBZ for chorea associated with Huntington's disease (HD). Nineteen patients (12 female), mean age 56.3 +/- 12.4 years (range 37-76 years) diagnosed with HD were prospectively evaluated at initial and follow-up visits using a modified Abnormal Involuntary Movement Scale (AIMS). Patients were videotaped, and the randomized videotapes were rated with the motor subset of the AIMS by two investigators who were blinded to treatment assignment. Eighteen patients completed and were rated after 5.9 +/- 3.3 months (range 2-11) at a final mean TBZ dose of 62.5 +/- 37.4 mg/day (range 25-150). The blinded videotaped motor scores showed that 15 were better on TBZ, 2 were better before TBZ, and 1 was unchanged (p < 0.001, Wilcoxon signed rank test). The mean score improved from 16.2 +/- 4.8 to 12.8 +/- 4.4. Adverse events included akathisia, insomnia, constipation, depression, drooling, and subjective weakness. All 18 of these patients have continued to take TBZ since completion of the study. TBZ was well tolerated and resulted in a significant improvement in modified AIMS scores in HD patients. These results support the use of TBZ for chorea in patients with HD.

Stimulants are a highly efficacious and safe treatment for attention-deficit/hyperactivity disorder (ADHD), with 75% to 90% of patients responding well if two different stimulants (amphetamine and methylphenidate) are used. Nonetheless, a subset of ADHD patients will either fail to respond to stimulants or have side effects that preclude their use (tics, severe loss of appetite, marked insomnia). For such patients, there are a number of non-stimulant agents that serve as second-line treatments. Tricyclic antidepressants (TCAs) are the most studied of these drugs. They are superior to placebo in the treatment of ADHD and may reduce abnormal movements in patients with ADHD/tic disorder. TCAs often produce side effects of sedation, dry mouth, and constipation. Bupropion is superior to placebo in the treatment of ADHD and has a more favorable side-effect profile than the TCAs. A new selective norepinephrine reuptake inhibitor, atomoxetine, has been shown to be efficacious in the treatment of ADHD and has recently received an approvable letter from the Food and Drug Administration. The a-agonists clonidine and guanfacine have also been used as alternative agents in ADHD, though the controlled data are more limited. A recent controlled clinical trial suggests a combination of methylphenidate and clonidine has advantages in the treatment of comorbid ADHD and tics over either medication alone. Clinical guidelines for each of these agents, as well as their use in combination with stimulants in comorbid conditions, will be discussed.

The aim of the present study was to evaluate the efficacy and safety of an immediate switch to reboxetine, a selective noradrenaline reuptake inhibitor (selective NRI), in patients with depression unresponsive to the selective serotonin reuptake inhibitor (SSRI) fluoxetine. The study included 128 adult outpatients with DSM-IV major depressive disorder (MDD) who had not responded to at least 6 to 12 weeks of fluoxetine treatment, with at least 3 weeks of treatment on a minimum dose of 40 mg/d. Patients were switched, without a washout period, to reboxetine 4 mg twice daily, with the possibility of increasing the dose to 10 mg/d (given in divided doses) after 4 weeks of treatment. Efficacy was assessed using the 17-item Hamilton Rating Scale for Depression (HAM-D-17) and the Clinical Global Impression Improvement (CGI-I) and Severity (CGI-S) scales. Safety was evaluated by recording spontaneously reported adverse events.A statistically significant (P < 0.001) improvement in the mean total HAM-D-17 score was seen from baseline by week 1 of treatment with reboxetine, and the improvement continue to week 8. CGI-I and CGI-S scores were similarly improved. The switch to reboxetine was well tolerated; the most common treatment-emergent adverse events were insomnia, headache, dry mouth, diaphoresis, and constipation, all of which were mild to moderate in severity and decreased in frequency as the study progressed.Immediate switching to reboxetine appears to be a safe and effective treatment for patients with depression who have failed to respond to an adequate dose of fluoxetine.

Obesity is a multifactorial, chronic disorder that has reached epidemic proportions in most industrialised countries and is threatening to become a global epidemic. Clinical management of obese patients is complex and serious doubts have arisen with regard to safety and efficacy of drug therapy. Following the withdrawal of fenfluramine and dexfenfluramine in 1997, interest has focused on novel anti-obesity drugs. Pharmacological approaches to the management of obesity can, in broad terms, use different distinct strategies: firstly, to reduce energy intake; secondly, to increase energy expenditure; and thirdly, to alter the partitioning of nutrients between fat and lean tissue. Sibutramine is a serotonin-noradrenaline (norepinephrine) reuptake inhibitor indicated for the management of obesity in conjunction with a reduced calorie diet. The pharmacological mechanisms by which sibutramine exerts its weight loss effect are likely due to a combination of reduced appetite, feelings of satiety and possibly the induction of thermogenesis. The efficacy of sibutramine for inducing initial weight loss and the subsequent maintenance of weight loss is well proven in short- and long-term clinical trials of up to 2 years' duration. Most individual placebo-controlled trials and pooled estimates found that the drug produced statistically significant greater weight loss than placebo at all observed endpoints (weighted mean difference for weight change at 8 weeks: -3.4 kg; mean difference range for weight change at 6 months: -4.0 to -9.1 kg; and at 1 year: -4.1 to -4.8 kg). The most frequent dosage regimen in these trials was 10-20 mg daily. Findings suggested a dose-effect relationship in terms of weight loss. Sibutramine was also associated with better weight maintenance relative to placebo (statistically significant difference). Results from mainly small trials showed that sibutramine produced more favourable outcomes in terms of loss of fat mass, reduction in body mass index and loss of > or = 5-10% of initial bodyweight. The most commonly reported adverse effects of sibutramine are headache, constipation and nausea. Certain adverse events associated with the nervous system, including dizziness, dry mouth and insomnia, are reported by > 5% of patients receiving sibutramine. Increases in blood pressure and heart rate were possible adverse effects that require regular monitoring especially in obese hypertensive patients. Neither left-sided cardiac valve disease nor primary pulmonary hypertension was associated with the use of sibutramine. The assessment of the benefit-risk profile of sibutramine remained positive, although the product must be kept under regular review.

Rapidly after its appearance in France, interesting properties were attributed to chocolate and it was used in medicine,often wrongly, to treat digestive, pulmonary, nervous, even infectious diseases, and also for its nutritive and aphrodisiacal capability... But it was already charged with insomnia or constipation. During the XIXth century, chocolate was used as food and as an excipient for dissimulation and transportation of drugs. Medicinal chocolates were essentially nutritive and analeptic, pectoral, stomachic, purgative or anthelmintic. All of them have disappeared today, but the pharmacological interest of chocolate remains with its antidepressive activity and the promising proposes of some of its components. However, chocolate is still considered to be responsible of constipation, headache or pimples...

We propose a unifying hypothesis that many clinical consequences of aging are pleiotropic manifestations of the loss of parasympathetic function that occurs during post-reproductive senescence. The loss of parasympathetic function unmasks the baseline sympathetic bias inherent in the end-organs, resulting in the familiar signs of aging including tachycardia, constipation, insomnia, erectile dysfunction, fluid retention, and systemic inflammation. These consequences in turn may contribute to many of the common diseases associated with aging including type-2 diabetes, Alzheimer's, atherosclerosis, and cancer. Maintenance and restoration of parasympathetic function may enable upstream control over the deleterious aspects of inherent end-organ adrenergic bias.

Atomoxetine is the first nonstimulant drug approved by the United States Food and Drug Administration (FDA) for the treatment of attention-deficit-hyperactivity disorder (ADHD), and the only agent approved by the FDA for the treatment of ADHD in adults. Atomoxetine is a norepinephrine transport inhibitor that acts almost exclusively on the noradrenergic pathway. Its mechanism of action in the control and maintenance of ADHD symptoms is thought to be through the highly specific presynaptic inhibition of norepinephrine. Clinical trials to evaluate the short-term effects of atomoxetine in children and adults have shown that atomoxetine is effective in maintaining control of ADHD. Likewise, long-term trials have determined that atomoxetine is effective in preventing relapse of ADHD symptoms without an increase in adverse effects. A comparative trial of atomoxetine with methylphenidate in school-aged children indicated similar safety and efficacy without the abuse liability associated with some psychostimulants. The most commonly reported adverse effects in children and adolescents are dyspepsia, nausea, vomiting, decreased appetite, and weight loss. The rates of adverse events in the trials were similar for both the once- and twice-daily dosing regimens. The discontinuation rate was 3.5% in patients treated with atomoxetine versus 1.4% for placebo and appeared to be dose dependent, wit a higher percentage of discontinuation at dosages greater than 1.5 mg/kg/day. In clinical trials involving adults, the emergence of clinically significant or intolerable adverse events was low. The most common adverse events in adults were dry mouth, insomnia, nausea, decreased appetite, constipation, urinary retention or difficulties with micturition, erectile disturbance, dysmenorrhea, dizziness, and decreased libido. Sexual dysfunction occurred in approximately 2% of patients treated with atomoxetine. Atomoxetine should be used with caution in patients who have hypertension or any significant cardiovascular disorder. Overall, atomoxetine therapy in patient with ADHD appears to be effective in controlling symptoms and maintaining remission, with the advantages being comparable efficacy with that of methylphenidate, a favorable safety profile, and non-controlled substance status. Additional long-term studies are needed to determine its continued efficacy for those who require lifelong treatment, and comparative trials against other stimulant and nonstimulant agents.
