We compared the patient acceptance and efficacy of 60 mg extended-release fenfluramine and placebo before the evening meal in a 10-week, double-blind trial. All 51 participants were 130% to 180% of ideal body weight. They received instruction in diet and behavior modification for 2 wk before the beginning of and during the medication period. Mean weight loss was 5.9 kg (8.0 +/- 4.6% of initial weight) in the fenfluramine group and 3.3 kg (5.5 +/- 3.5%) in the placebo group. Fenfluramine-treated participants reported lower hunger ratings and greater fullness in the target supper-to-bedtime period than participants receiving placebo. Both groups reported dry mouth, dizziness, drowsiness, fatigue, and diarrhea. Although the fenfluramine group reported more complaints, these diminished to less than half after 2 wk of treatment. Four of the fenfluramine and three of the placebo group dropped out for drug-related reasons. In all, 10 fenfluramine and 8 placebo participants dropped out. Fenfluramine participants had a higher benefit score with no difference in risk scores. The fenfluramine group's global evaluation was better than that of the placebo group. Participants viewed the study and the dosing regimen positively but had negative ideas about anorexiants in general. Extended-release fenfluramine taken in the evening was well tolerated and maintained its efficacy as measured by standard and novel techniques.

Obsessive-compulsive disorder is a chronic psychiatric illness, affecting up to 3% of the general population, to the middle of 60-th it was supposed to be untreatable. Antidepressant pharmacotherapy is one of the treatment alternatives today. We compared efficacy and safety of citalopram versus clomipramine (serotoninergic antidepressants) in 6 weeks in double blind therapy of obsessive-compulsive disorder. The second objective was to compare prolactin response to a fenfluramine challenge test before the treatment of patients and after 6 weeks of the treatment. In a sample of 14 patients we confirmed significant therapeutic response after 3 weeks of pharmacotherapy, better in obsession than in compulsion. We found low level of adverse effects in the first week of therapy--dry mouth, anxiety, nausea, somnolence, tremor, and sexual adverse events. There were no changes in the laboratory, test EEG, and ECG examinations. Fenfluramine challenge test showed statistically significant decrease of prolactin levels 1 hour after administration of fenfluramine. It was not observed after six weeks of the therapy. Statistically significant negative correlation between prolactin plasma levels at the 6th hour after administration of fenfluramine and obsession item of YBOC Scale was showed after the 3rd and 6th week of the therapy. The correlation was not observed for compulsion item YBOC Scale. Side effects observed during and after the challenge test were anxiety and nervousness and gastrointestinal problems, lasted from 1 hour to 10 hours. These preliminary result could support the idea, that obsessions and compulsions have not necessary the same biological background. The challenge paradigm appears to be a possible way to clarify the pathogenesis of OCD. Our study will continue.

Past and current drug therapies for weight loss are discussed. More than 50% of Americans can be categorized as overweight or obese. Obesity is associated with increased mortality and with comorbidities such as hypertension, hyperglycemia, dyslipidemia, coronary artery disease, and certain cancers. According to guidelines for identification, evaluation, and treatment of obesity, patients with a body mass index (BMI) of > or = 30 kg/m2 should attempt to lose weight. Patients with a BMI of > or = 25 kg/m2 plus two or more risk factors or patients with an excessive waist circumference plus two or more risk factors should also attempt to lose weight. The initial goal is a 10% weight reduction in six months achieved through lifestyle changes. If lifestyle changes alone are not effective, then drug therapy may be indicated. Pharmacotherapeutic options for obesity have decreased over the past few years. Fenfluramine, dexfenfluramine, and phenylpropanolamine have been withdrawn because of severe adverse effects, leaving only sympathomimetics, sibutramine, and orlistat as anorectics with FDA-approved labeling. Phentermine has been shown to cause a 5-15% weight loss if given daily or intermittently. Compared with sibutramine and orlistat, phentermine is cheaper, and specific formulations allow once-daily administration. However, phentermine is indicated only for short-term treatment, and tolerance often develops. Common adverse effects associated with phentermine are dry mouth, insomnia, increased blood pressure, and constipation. Sibutramine increases norepinephrine and serotonin levels in the CNS and should not be taken with many antidepressants because of the risk of increased norepinephrine and serotonin levels. Its use is also contraindicated in patients with cardiovascular disease. Orlistat is not systemically absorbed; therefore, it does not cause the systemic adverse effects or drug interactions of phentermine and sibutramine. Orlistat has a cholesterol-lowering effect not seen with other diet medications. However, the three-times-daily administration and frequent gastrointestinal effects limit its use. Sibutramine, phentermine, and orlistat have both positive and negative properties. Choosing among the medications will depend on concurrent disease states and medications, ease of administration, and cost.

We have studied the therapeutic effects of two different doses (30 mg and 60 mg, twice daily) of DL-fenfluramine (DL-F) in, respectively, prepuberal (11-13 years old) and adolescent subjects (14-17 years old). Sixty-eight obese subjects were recruited for this study (22 boys, 36 girls, aged 10-17 years old) with body mass index ranging from 24.5 to 44.0 kg/m2, absolute weight ranging from 37.0 to 119.5 kg and % over IBW ranging from 122% to 260%. Results were compared to a placebo treated group of obese adolescent patients (n = 17), 6 boys and 11 girls, aged 10-17 years old, BMI ranging from 26-44 kg/m2, absolute weight 53.1 to 96.5 kg, and with 129% to 253% over IBW. In the DL-F-treated subjects most patients (n = 41) had a continuous weight loss during 12 months but 27 individuals were unable to lose any additional weight after the initial 6 months of the trial. Taken together 65% of all patients lost weight during DL-F treatment (12 months) whereas only 17.4% of the placebo group lost a significant (> 10% BMI) amount of excess weight. Also the placebo group had a higher withdrawal rate (57%) as compared with the DL-F-treated group (24%). There was a significant (p < 0.05) decrease of the mean +/- SD of the BMI (at 6 and 12 months of therapy). No significant change of the BMI was observed for control group. Minor adverse side effects consisted of a brief period of drowsiness and dry mouth. Our findings indicated that the continuous administration of DL-Fenfluramine might help obese adolescent subjects adhere to a diet and to maintain the weight loss achieved without major or harmful adverse effects.
