Persons who contacted the Anorexia/Bulimia Association of Norway for information and stated that they had an eating disorder were asked to participate in this questionnaire study. The answers from the 32 women who fulfilled the DSM-III-R criteria for bulimia nervosa are presented. Usually the women's eating problems had started in the teens after a period of voluntary dieting. The mean duration of bulimia nervosa was six years. 31% had a history of anorexia nervosa. At the time of the study almost all had normal body weight, but nevertheless felt overweight. 78% practised self-induced vomiting, 22% used laxatives and 16% used diuretics to reduce weight. Depressive and anxiety symptoms were common in connection with the overeating episodes, but also more generally, which interfered with everyday life. Somatic symptoms (abdominal pain, diarrhoea, constipation, dyspepsia, headache, dry mouth and eyes, parotid gland swelling, muscular symptoms, fatigue, and oligomenorrhoea) were also common.

International study of the effect of dexfenfluramine in obesity (ISIS): 6 months results. ISIS is a multicentre therapeutic trial of the "intention to treat" type organized to test the effectiveness and side-effects of dexfenfluramine combined with diet in the treatment of obesity. This was a randomized, double-blind drug versus placebo study programmed for a one-year period. Eight hundred and twenty-two obese patients were included. Dexfenfluramine was administered in doses of 15 mg b.d. The intermediate results after 6 months of treatment are presented. Significant differences were observed between the dexfenfluramine group (n = 404) and the placebo group (n = 418). In the treated group: 1) the drug withdrawal rate was lower, mainly due to a greater number of patients in the placebo group dissatisfied with their weight loss; 2) about twice as many patients achieved an important loss of weight in terms of percentage of the initial weight or overweight; 3) the cumulative loss of weight was greater; 4) there was a higher incidence of transient side-effects, such as fatigue, diarrhoea, dry mouth, polyuria and drowsiness. These results suggest that dexfenfluramine will be suitable for a more prolonged treatment of obese patients, in addition to diet.

We added phenylpropanolamine OROS (Acutrim; Ciba-Geigy Corp.) or placebo to a physician-managed behavior modification, mild caloric restriction, and exercise weight control program. One hundred six healthy, overweight (115% to 130% ideal body weight) women participated in this 14-week double-blind clinical trial. On average, the participants who took Acutrim lost significantly more weight (X +/- SE; 6.1 +/- 0.6 kg; 8.0% +/- 0.8%) than did those taking placebo (4.3 +/- 0.7 kg; 5.5% +/- 0.8%; P less than 0.05). Those taking Actrim continued to lose weight over the Christmas holiday, while the placebo group gained weight. Fifteen participants taking placebo withdrew, three because of adverse drug reactions (ADRs). Thirteen of 53 participants in the Acutrim group left the study, two because of ADRs. Dry mouth was the most frequent complaint from participants taking Acutrim. No serious cardiovascular effects occurred. Both complaints and the number of participants reporting ADRs decreased with continued dosing. We conclude that Acutrim is a safe, modestly effective adjunct to a physician-managed, integrated weight control program.

Dexfenfluramine increases serotonergic activity by stimulating serotonin (5-hydroxytryptamine; 5-HT) release into brain synapses, inhibiting its reuptake into presynaptic neurons and by directly stimulating postsynaptic serotonin receptors. On the basis of the serotonin hypothesis of appetite control, these actions would be expected to reduce appetite and, consequently, bodyweight. Studies conducted in animals and in overweight patients with and without associated disorders have confirmed the weight-reducing efficacy and good tolerability of dexfenfluramine. In 3-month clinical studies in obese patients, weight reductions with dexfenfluramine 15mg twice daily combined with dietary support were significantly higher than those achieved with placebo and similar to those with ephedrine/caffeine 20/20mg 3 times daily, sibutramine 10mg once daily and fluoxetine 60 mg/day. Furthermore, dexfenfluramine recipients with non-insulin-dependent diabetes mellitus, hyperlipidaemia or hypertension consistently show improvements in glycaemic control, blood lipid profiles and blood pressure. 12-month trial results indicate that most weight loss occurs in the initial 6 months and appears to be maintained for a further 6 months. Weight regain after withdrawal of treatment in 12-month studies demonstrates that dexfenfluramine is effective in maintaining a stable bodyweight at a lower level than placebo and in limiting food intake over this time period. Commonly reported adverse events with dexfenfluramine include diarrhoea, tiredness, dry mouth and somnolence; these symptoms are generally mild and transient. Approximately 7 and 10% of dexfenfluramine recipients in short and long term studies withdrew because of adverse events. Dexfenfluramine was better tolerated than ephedrine/caffeine and fluoxetine in short term studies. Obesity is a chronic condition that is accompanied by a number of metabolic complications. It is a significant health problem in developed countries, and as a major risk factor for many chronic diseases, including diabetes and cardiovascular disease, the economic burden of this condition is considerable. As with other chronic conditions, there is a role for pharmacological intervention in patients with severe obesity. However, drugs should be considered as only one component of a weight-control programme, since additional lifestyle modification is required to maintain weight loss. The promising data on the long term efficacy and tolerability of dexfenfluramine as well as its favourable effects on risk factors associated with obesity requires confirmation in long term studies. In the meantime, dexfenfluramine should be considered a valuable adjunct to a reduced-calorie diet in the management of severe obesity, particularly in patients with associated disorders and those unsuccessful with conventional weight loss measures. Available data support the use of the drug for up to 1 year to maintain weight loss and thus dexfenfluramine should be considered for long term administration.

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.

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.

Sibutramine (Reductil, Abbott-Knoll, 10 mg and 15 mg) is a new appetite regulator recommended in the treatment of obesity. It is a noradrenaline and 5-hydroxytryptamine reuptake inhibitor which exerts its effects in vivo predominantly via its secondary and primary amine metabolites. Sibutramine is indicated as an adjunctive therapy within a weight management programme in patients with obesity (BMI > or = 30 kg/m2) or in overweight subjects (BMI > or = 27 kg/m2) if other eight-related risk factors are present (dyslipidaemias, diabetes mellitus). In those patients with an inadequate response on initial dose of 10 mg per day (suggested as less than 2 kg weight loss in four weeks), the dose may be increased to 15 mg once daily, providing that sibutramine is well tolerated. Several large-scale randomized clinical trials demonstrated the efficacy of long-term (at least one year) treatment with sibutramine in obese subjects with or without type 2 diabetes. Sibutramine was also shown to help in maintaining long-term weight reduction. Most frequent side-effects are dry mouth and constipation, as well as mild increase in heart rate and arterial blood pressure. The impact of sibutramine on cardiovascular morbidity and mortality of obese nondiabetic and diabetic patients will be studied soon in a large international prospective clinical trial.

This 6-month randomized study evaluated the safety and efficacy of sibutramine in 57 overweight Hispanic patients with hypertension. Following a 2-week washout to confirm the diagnosis of hypertension, antihypertensive medication was adjusted to achieve a blood pressure less than 140/90 mm Hg before institution of either sibutramine 10 mg or placebo once a day. A body mass index in excess of 27 kg/m2 was required for entry. At study end, weight had changed from 75.4+/-9.6 to 70.0+/-9.5 kg in the sibutramine group and from 77.9+/-9.0 to 74.5+/-9.4 kg in the placebo group. In the sibutramine group, systolic blood pressure was 127.8+/-5.8 mm Hg after stabilization and 125.2+/-8.5 mm Hg after completion of the trial; respective values for diastolic blood pressure were 82.4+/-3.7 and 81.5+/-4.6 mm Hg. With placebo, blood pressure dropped from 129.0+/-7.1/80.9+/-4.9 mm Hg to 122.8+/-9.7/80.3+/-5.4 mm Hg at the same timepoints. In the sibutramine group, 14 patients reported 21 adverse events, most frequently headache (n=5), constipation (n=4), and dry mouth (n=4). In the placebo group, 13 patients had 20 adverse events. Sibutramine is safe and effective in overweight Hispanic patients with hypertension, but monitoring of blood pressure and titration of antihypertensive medication are necessary.

The overweight and obesity represent severe problems for the health management system of developed countries. In the evolution of obesity, beside genetic background, the environmental factors also play important roles. In the daily routine, the majority of obese patients need drug treatment, over the diet and physical activity. Among the available medicines the inhibitors of monoamine re-uptake causes dry mouth, tachycardia, sleeplessness and elevated blood pressure, therefore, due to the frequently associated obesity and hypertension many physicians avoid using these compounds. The orlistat as a selective inhibitor of pancreatic and enteral lipase enzymes impedes the absorption of the highest calorie containing nutrients, the fats exerting beneficial effects in the treatment of obesity. The abdominal bloating and diarrhea as side effects of the drug may act as an advantage in many cases, since these happen especially in those cases when the patient neglects the previously suggested low fat diet and therefore the drug induced diarrhea and bloating may mean a feed-back for the patient in respect of the proper diet. Recent studies show many beneficial biochemical changes in obesity related pathological metabolic processes during the administration of orlistat. The authors, in their present work review in short the role of orlistat in the treatment of slimming cure.

Uncertainties about the cardiovascular safety of sibutramine led to the SCOUT trial that is investigating sibutramine plus weight management in high-risk, overweight/obese patients. A 6-week lead-in period during which all patients received sibutramine permitted an initial assessment of tolerability. A total of 10,742 patients received sibutramine and 3.1% of these discontinued due to an adverse event; issues affecting more than 10 patients were drug intolerance, headache, insomnia, nausea, dry mouth, and constipation-, tachycardia-, and hypertension-related events. Serious adverse events, most commonly associated with the System Organ Class, Cardiac disorders, were reported by 2.7% of patients; however, the majority was not considered sibutramine-related. Adverse events relating to high blood pressure and/or pulse rate, whether reported as adverse events leading to discontinuation, or serious adverse events were reported by less than 0.2% of patients. No serious or individual events leading to discontinuation occurred in more than 25 patients. There were 15 (0.1%) deaths; 10 were attributed to a cardiovascular cause. Discontinuations for adverse events were lower than anticipated. Serious adverse events generally reflected sibutramine's known pharmacology or were related to cardiac disorders already present in this high-risk population. When compared with epidemiological data, overall mortality rate was low and sibutramine was well tolerated in this mainly off-label population. No new safety issues were detected.
