The administration of ephedrine and caffeine (E+C) has been proposed to promote weight loss by increasing energy expenditure and decreasing food intake. We tested this hypothesis in six lean (4-9% body fat) and six mildly to moderately obese (13-44% body fat) monkeys studied during a 7-wk control
In previous separate studies, dexfenfluramine (DF) and ephedrine/caffeine (EC) have been shown to promote weight loss in obese patients as compared with placebo. In order to compare the efficacy and safety of these two anorectic drugs, 103 patients with 20-80% overweight were included in a 15-week
Treatment with beta 2-agonists promotes fat loss and muscle growth in numerous species, but human studies are lacking. We studied the effect of a compound with beta 2-agonistic properties (ephedrine 20 mg/caffeine 200 mg [E + C]). Fourteen obese women were treated with a 4.2-MJ/d diet and either E +
OBJECTIVE
To determine whether or not aspirin further potentiates the greater post-prandial thermogenesis induced by ephedrine with caffeine.
METHODS
Determination of the acute metabolic rate response to the following treatments: 1050 kJ liquid meal (M); meal plus ephedrine (30 mg) and caffeine (100
Low caloric diet is a commonly accepted treatment in obesity. However, owing to moderate results, a pharmacological support has been proposed. As some efficacious drugs activate overall sympathetic activity, they might modify functions of the cardiovascular system. Three groups of subjects were
OBJECTIVE
To evaluate the efficacy and side effects of an herbal formulation to promote weight loss, as compared to placebo.
METHODS
12-week multicenter double-blind, placebo-controlled, randomized parallel groups design. Study conducted at three clinical sites in New York State. Subjects were
OBJECTIVE
To investigate whether the beta(3)-adrenoceptor could be identified by immunohistochemistry in intact human white and brown adipocytes and other human tissues, and to investigate the influence of obesity and its treatment with ephedrine and caffeine on the expression of the
Cardiolipin (CL) is crucial for mitochondrial energy metabolism and structural integrity. Alterations in CL quantity or CL species have been associated with mitochondrial dysfunction in several pathological conditions and diseases, including mitochondrial dysfunction-related compound attrition and
Adipsin gene expression is greatly diminished in certain forms of genetic and acquired obesity. In the present study we evaluate the time course for the development of adipsin deficiency in obesity and its regulation by the sympathomimetic-thermogenic drug mixture ephedrine and caffeine. Previously,
The effect of ephedrine (E) and theophylline (T), administered alone and in combination (E/T), on weight loss, resting energy expenditure and post-heparin lipoprotein lipase activity in plasma (PHLA) and in adipose tissue (ATLP) were investigated in obese over-fed rats, who had been diet restricted
1. We investigated the effects of the chronic administration of a sympathomimetic agent on energy expenditure, protein metabolism and levels of thyroid hormones and catecholamines in 10 obese subjects after a 6-week very-low-calorie-diet programme (1965 kJ, 60 g of protein, 45 g of carbohydrates).
OBJECTIVE
With an increase in the incidence of obesity, tremendous effort has been devoted to the development of weight loss agents and the prospective surrogate markers of both a product's efficacy and safety. The objective of the present study was to compare the pharmacodynamic responses of
In 8 obese women the effect was assessed of ephedrine (Ephedrinum hydrochloricum, Polfa) on gastric emptying after solid food. The authors found that ephedrine in a dose 50 mg p.o. revealed a significantly inhibiting of the gastric emptying in obese women.
Chronic administration of aspirin to obese mice had no effect on energy balance and body composition. In contrast, ephedrine increased energy expenditure by 9% and reduced body weight and body fat by 18% and 50%, respectively: obesity, however, was reduced but not reversed. In the presence of both
A double-blind cross-over randomized study was performed in 10 selected adult overweight and obese (body mass index greater than 27) women who had been adapted to low-energy intake for a long period of time and who had shown difficulty in losing weight with conventional hypocaloric treatment.
