Weight loss due to sibutramine and energy restriction is associated to better metabolic control in type 2 diabetic obese patients 61, Human studies to assess thermogenic effects As previously mentioned, different animal studies have shown thermogenic action of various b-phenethylaminic derivates and mazindol Their effects in human studies are not so clear, and contrasting results are frequently attributed to the heterogeneity of the obese patients studied.

While some authors have shown higher resting metabolic rate, as well as higher response to feeding after dexfenfluramine administration 49,50 , or attenuation of the usual decrease in resting metabolic rate during low-calorie diet in post-menopausal women in a three-month treatment period 51 , others have found no difference in hour energy expenditure after 1 week, 3 months 40 , or even 13 months under dexfenfluramine or placebo Human data are also conflicting in sibutramine studies.

In one study, no difference was found between baseline metabolic rate and three hours after the administration of sibutramine or placebo, neither after an 8-month treatment with sibutramine However, when calorie expenditure was measured for a 5-hour period, there was an increase in thermogenesis both while fasting and after feeding in the last 3,5 hours after sibutramine administration. Such effect was not observed in the first study Phenylpropanolamine is an a1adrenergic agonist widely used in the United States for many years.

In Brazil, experience with this agent is more limited. Only patients receiving phenylpropanolamine had a weight loss significantly higher than the placebo group, even though no difference was observed in resting metabolic rate measured by indirect calorimetry Ephedrine belongs to the phenylpropanolamines group and stimulates the release of noradrenaline.

Structural changes result in increased peripheral action while reducing central action on adrenergic receptors. Ephedrine causes a non-selective stimulation of sympathetic nervous system by acting on b-adrenoceptors b3 included and promoting thermogenesis Ephedrine has been studied in obese women, at 60 mg daily dose for 12 weeks, resulting in baseline metabolic rate increase.

Ephedrine associated with methylxantins like caffeine, teophyilline and aminophylline or aspirin increases the duration of noradrenalin activity.

Adenosin and prostaglandins, which decrease noradrenalin activity, are inhibited by caffeine and aspirin. Phosphodiasterase inhibition through caffeine seems to be the most important effect, since that enzyme is responsible for cyclic AMP metabolization, and its inhibition maximizes noradrenalin action 59, Different combinations of caffeine and ephedrine have been analyzed in double-blind studies whose conclusion was that higher synergy occured at the dose of mg caffeine and 20 mg of ephedrine 3 daily administrations In a randomized, double-blind study conducted by our group, 3 daily doses of a combination of ephedrine 22 mg, caffeine 20 mg and aminophylline 50 mg, resulted in a significantly higher weight loss, as compared to the group of patients not receiving the association, although baseline energy expenditure through calorimetry was not assessed In a more recent study, 17 women with BMI of Clinical trials and case reports in humans Twenty-five years ago, an analysis including over double-blind, controlled studies concerning appetite reduction medications including amphetamine, phentetrazine, benzophetamine, fendimetrazine, phentermine, chlorphentermine, chlotermine, mazindol, fenfluramine and diethylpropion was submitted to FDA to justify registrations of new drugs.

Ninety percent of them showed a higher weight loss in the group of patients receiving active medication. A total of 4, patients were evaluated receiving placebo and 3, receiving active ingredients 8. Table 2 shows a selection of 41 studies on phenethylaminics or tricyclics diethylpropion, mazindol, phentermine, fenfluramine, dexfenfluramine , which lasted at least 10 weeks.

Most of these studies are also described in another review 6. Those medications fill the criteria currently used for anti-obesity medications, except for fenfluramine and dexfenfluramine. These 2 medications were withdrawn from world market in due to valvular abnormalities developed under combined therapy of phentermine plus fenfluramine but not under phentermine monotherapy 63,64 , similar to carcinoid syndrome lesions.

A larger prospective study with 1, participants did not detect increased risk of valvular injuries in patients using sustained-release dexfenfluramine for less than 3 months A case-control study including 95 patients with pulmonary hypertension and matched controls showed that fenfluramine use was associated with pulmonary hypertension odds ratio [OR] 6.

OR was higher in patients under fenfluramine for less than 12 months OR Only one case of pulmonary hypertension, 12 months after interruption of mazindol therapy in a patient who had received for 10 weeks, was recently reported Isolated cases of pulmonary hypertension 69 and psychosis 70 were associated to diethylpropion. Although sibutramine is also a phenethylaminic derivate, it does present quite a different profile and much better tolerability.

Table 3 summarizes sibutramine studies in which this agent was used for 10 weeks up to two years. References of these studies can be checked in another review published by the authors 6.

Nevertheless, hypertension was seen as its major adverse effect, resulting in discontinuation of patients in the study Thumbnail In Brazil, when phenylpropanolamine was used, controlled prescription was required. In contrast, for many years, in the US, this was an over-the-counter medication, more widely used than in our country.

Phenylpropanolamine was removed from the American and Brazilian markets in Selective inhibitors of serotonin reuptake Both fluoxetine and sertraline are selective inhibitors of serotonin reuptake despite diverse chemical structure. Fluoxetine is a phenylpropanolamin oxyfluorphenyl derivate and sertraline is a naftilaminic one. Fluoxetine and sertraline inhibit serotonin reuptake at the pre-synaptic terminal; their main indication is to treat depression and bulimia, and they are not formally indicated to treat obesity.

Both agents were found to reduce animal feeding experimentally In humans, weight loss was a common finding during protocols for the approval of those medications as anti-depressants. Human studies to assess food intake Clinical trials to assess feeding reported the effect of those medications on patients' food intake size Endocrine and metabolic effects A study including diabetic subjects reported that fluoxetine treatment was associated with a higher weight loss and their insulin requirements were reduced Human clinical trials The key problem involving fluoxetine as anti-obesity agent is weight regain, as detected in long-term studies.

In general, after the first 6 months of treatment, body weight is gradually recovered, although medication is maintained. A study to assess weight loss under sertraline showed no difference when compared to the placebo groups In another, sertraline increased the weight loss of patients under cognitive-behavioral treatment Double-blind fluoxetine studies with at least week duration are shown in table 3.

References are detailed in another review published by the authors 6. Fluoxetine therapy for obesity management has been associated with gastrointestinal symptoms, sleep disorders, reduced libido, sweating, amnesia and thirst Selective inhibitors of serotonin reuptake are not, therefore, efficacious anti-obesity agents, although they may be useful for depressed obese patients, and for patients reporting other comorbidities for which those anti-depressants may be an appropriate treatment - for instance, sleep apnea - since fluoxetine leads to REM reduction, when most episodes of obstructive apnea occur.

Nutrients metabolism post-absorptive modifiers Lipstatine analogues Lipstatine is a compound from yeast - Streptomyces toxytricini. Orlistat is a stable lipstatine analogue, and partially hydrolized tetra-hydrolipstatine. Clinical pharmacokinetics Orlistat is a powerful inhibitor of gastrointestinal GI lipases. Such enzymes catalize hydrolytic removal of triglycerides fatty acids and produce free fatty acids and monoglycerides. Orlistat binds irreversibly to lipase active sites through covalent binding.

Approximately one-third of triglyceride intake does not undergo digestion, and is not absorbed by small intestines, crossing the GI tract and being eliminated. Orlistat has no systemic activity, and absorption by GI is minimal when administered up to mg daily, with lipase inhibiting activity pharmacologically irrelevant from 1, to 2, times lower than orlistat Human studies to assess human intake Orlistat has no direct effect on appetite regulating neuronal circuits.

However, its pharmacological effect reflected by the increased amount of fat in feces stimulates long-term compliance to lower fat content food intake Cardiovascular effects Weight loss resulting from orlistat is associated with significant reduction of systolic and diastolic blood pressure as compared to placebo Endocrine and metabolic effects As previously mentioned, weight loss leads to the reversion of some obesity-associated disorders.

This occurs even with modest weight loss but benefits are improved with intentional weight loss of greater magnitude. In non-diabetic obese patients, the use of orlistat combined with calorie-fat restriction is associated with significant reductions in insulin A one-year study, including controlled diabetic subjects under sulfonylureas, resulted in significant reduction of plasma glucose and glycated hemoglobin levels, as well as in the number of patients discontinuing oral anti-diabetic treatment Those data have been confirmed by a Latin American multicenter 6-month-long trial Human clinical trials The first orlistat clinical trials were week long and multi-dosage, at 10 mg, up to mg, 3 times a day 87, Another study, six-month long, was carried out at 30, 60, , and mg of orlistat, 3 times a day Higher doses did not increase the weight loss.

Table 4 presents a selection of clinical trials concerning orlistat, also including diabetic subjects. The references of these studies can be checked in another review published by the authors 6.

Trials under analysis reported no differences in the frequency of GI adverse effects comparing orlistat and placebo groups. GI effects are related to orlistat mechanism of action oily stools, increased number of evacuation episodes, flatulence with or without fat discharge, fecal urgency ; they are usually short-term and tend to decrease considerably after the first weeks of treatment.

Such pattern seems to be related to the long-term patient compliance to low-fat foods. The authors evaluated the efficacy and tolerability of sibutramine combined to orlistat at regular doses up to 6 months in patients women and 93 men In this study, the combination of sibutramine and orlistat for obesity management resulted in higher weight reduction when compared to randomized clinical trials, and tolerability was quite reasonable.

The use of pharmacological agents in childhood obesity management Current clinical approach towards pediatric obesity mainly involves cognitive-behavioral therapies focusing eating and exercising pattern changes. Foccus on the pathophysiology of obesity may lead to the development of the appropriate medications both for adults and children, possibly from substances regulating metabolic economy physiology. Orlistat already proved to be effective and its use is approved for teenagers.

Development of trials in children and teenagers is critical, since one cannot assume that risks and benefits from the use of pharmacological agents in adults will be the same in children Use of anti-obesity agents in obese type 2 diabetic patients Weight reduction has been shown to improve glycemic control and cardiovascular risk associated with insulin resistance in obese individuals with type 2 diabetes mellitus.

Therapeutic options for these patients include promotion of weight loss non-pharmacologic and pharmacologic treatments , which improves glycemic control, as well as treatment of commonly associated risk factors, such as hypertension and dyslipidemia.

A recent review provides an overview of anti-obesity drugs used in the treatment of obese individuals with type 2 diabetes. The most widely investigated drugs, sibutramine and orlistat, resulted in modest, clinically worthwhile weight loss, but with marked improvement in several comorbidities, among them, type 2 diabetes. Studies involving these anti-obesity medications in cohorts of obese diabetic patients have been reviewed, as well as involving cathecolaminergic diethylpropion [amfepramone], fenproporex, mazindol, ephedrine-caffeine combination , serotoninergic agents fenfluramine, dexfenfluramine, fluoxetine , and others showing any benefit on weight loss metformin, the anti-epileptic agent topiramate and zonisamide, and the antidepressive bupropion [amfebutamone].

These trials showed variable benefits in terms of effects on glucose metabolism Orlistat was reported to prevent the development of type 2 diabetes in obese patients treated for 4 years XenDOS study Antagonists of endocannabinoid receptors The ability of marijuana to increase hunger has been noticed for centuries, although research on its action started in the late s. An endogenous neuromodulating system involved in feeding behaviour leads to the therapeutic use of a novel class of drugs, the selective cannabinoid type 1 receptor CB1R antagonists, for the treatment of obesity and eating disorders.

A 1-year blinded randomised clinical trial with doses of 5 mg or 20 mg of rimonabant was found to cause a pronounced reduction in bodyweight respectively Generally, it was well tolerated with mild and transient side effects mainly nausea WHO Consultation on Obesity.

Eur J Clin Pharmacol ; Efficacité[ modifier modifier le code ] La perte de poids obtenue avec l'orlistat est très variable, en particulier si sa prise est associée avec un régime hypocalorique plus ou moins rigoureux. La réduction moyenne de poids reste cependant inférieure à 3 kg [12].

Il existe également une amélioration des chiffres de la pression artérielle , une diminution du taux sanguin de cholestérol , dont le taux de LDL-choslestérol [12]. Ces trois facteurs vont dans le sens d'une diminution du risque de survenue de maladie cardio-vasculaire même si cela n'a pas été démontré. Son utilisation a fait partie, en , des recommandations anglaises pour la prise en charge de l'obésité [15].

Les effets secondaires[ modifier modifier le code ] Les principaux effets secondaires du médicament gastro-intestinal sont : la stéatorrhée , c'est-à-dire des selles grasses et molles, car l'orlistat bloque l'absorption de certaines des graisses alimentaires. Les matières grasses sont excrétées en l'état dans les selles ; l'incontinence fécale ; des diarrhées impérieuses : selles fréquentes ou urgentes ; Un météorisme , des douleurs abdominales à type de colique et des flatulences ; Une diminution du taux de sucre dans le sang pour certains patients diabétiques de type 2.

Les principaux effets indésirables de l'orlistat Alli ou Xénical sont liés à la présence de lipides dans l'alimentation. Les pharmaciens formés à cette prescription par les laboratoires conseillent, donc, de diminuer la part lipidique de l'alimentation lors du traitement, ce qui en soi est un régime qui permet une réduction pondérale.

Les effets indésirables qui se majorent avec les graisses alimentaires, le prix consacré au traitement et la durée de celui-ci l'étude Xendos parle de 4 années de traitement soit Euros pour sont des facteurs de motivation majeurs pour que les utilisateurs de cette molécule modifient positivement leurs habitudes alimentaires et adoptent ainsi le régime qu'ils n'avaient pu mettre en place sans ce traitement. Selon Roche, les effets secondaires sont plus graves au début de la thérapie et diminuent avec le temps [16].

Cette diminution des effets secondaires pourrait être associé avec la modification d'une alimentation devenant plus pauvre en matières grasses [17]. Le profil d'effets secondaires de l'orlistat a conduit des consommateurs américains du groupe Prescription Access Litigation d'attribuer son premier prix de la pire pilule à GlaxoSmithKline [18] , [19].

Certains patients peuvent développer des taux élevés d' oxalates dans les urines [2]. L'orlistat peut provoquer une atteinte hépatique [20]. Une hépatite grave reste toutefois exceptionnelle [21] et il est possible que ces accidents soient liés à d'autres facteurs que la prise de ce médicament [22]. Le comprimé Xenical dosé à mg d'Orlistat fut commercialisé en
