ABSTRACT
OBJECTIVE: A fixed-dose combination (FDC) of D-norpseudoephedrine, tri-iodothyronine, atropine, aloin, and diazepam is used in Mexico for the short-term treatment of obesity; however, its efficacy and safety have been scarcely studied. The aim of this study was to analyze the efficacy and safety of this FDC in Mexican adult overweight and obese patients by a prospective, uncontrolled, multicenter, phase IV open-label study. MATERIALS AND METHODS: 3,290 patients with a body mass index (BMI) Ë 27 kg/m2 were included in the current study. Primary outcome was the absolute body weight loss, whilst secondary outcomes were the improvement of anthropometric and cardiometabolic parameters as well as the description of adverse events. RESULTS: The FDC decreased the body weight and BMI by -9.0 ± 5.6 kg and -3.4 ± 2.2 kg/m2, respectively, at 6 months. In addition, 43.3% and 14.3% of subjects achieved at least 5% or 10% weight loss at 6 months, respectively. The FDC also significantly improved waist circumference, hip circumference, body fat, visceral fat, systolic blood pressure, diastolic blood pressure, diabetes risk, and mortality risk, at 3 and 6 months. Moreover, the FDC seems to have better results in the following order: obese grade 3 ≈ obese grade 2 Ë obese grade 1 Ë overweight patients. Mild mouth dryness, anxiety, and headache were the main reported adverse events. CONCLUSION: Data suggest that the FDC is effective and well tolerated for the short-term therapy of overweight and obesity in Mexican patients.â©.

Amfepramone, also known as diethylpropion, is an anorectic drug used for the short-term treatment of obesity; however, its efficacy and safety during periods greater than 3 months has been scarcely studied. To evaluate the 6-month efficacy and safety of amfepramone treatment in obese adult Mexican patients resistant to diet and exercise, a double-blinded, randomized, and placebo-controlled clinical trial study was designed on 156 volunteers with a body mass index (BMI) greater than 30 kg/m2 and less than 45 kg/m2. Patients were randomized to receive a 75 mg tablet of amfepramone or placebo daily for 6 months. Primary outcome was the absolute body weight loss, whereas secondary outcomes were the percentage of patients who achieved at least 5% or 10% weight loss, as well as the improvement of anthropometric and metabolic parameters. Amfepramone treatment produced a superior efficacy to decrease body weight than placebo at 3 months (-4.9±0.25 kg vs. -0.7±0.32 kg) and 6 months (-7.7±0.52 kg vs. -1.1±0.7 kg). In addition, 64 and 34 patients achieved at least 5% or 10% weight loss, respectively, with amfepramone at 6 months, compared with 8 and 0 patients on placebo. Amfepramone also significantly improved BMI and waist circumference, but it only showed a favorable tendency in the waist-hip index (WHI), glucose, total cholesterol, low-density lipoproteins (LDL), high-density lipoproteins (HDL), triglycerides, heart rate, systolic blood pressure, and diastolic blood pressure at 3 and 6 months. Amfepramone produced only mild adverse events, and they were presented in a greater number than placebo only at 3 months, dry mouth being the the main adverse event. Data suggest that amfepramone is effective and well tolerated in obese Mexican patients during a 6-month regimen.
