Metformin improves the weight reduction effect of mazindol in prediabetic obese Mexican subjects.

OBJECTIVE: Obesity is the strongest risk factor for type 2 diabetes (T2D). We aimed to explore 7% weight reduction rates of mazindol alone or combined with metformin in non-diabetic obese Mexican subjects who had additional risk factors for T2D. MATERIALS AND METHODS: In this randomized double-blind study, 137 participants received 1 mg mazindol (n = 65) alone or combined with 500 mg metformin (n = 72), twice a day, for 6 months. RESULTS: Mazindol and mazindol-metformin were similarly effective. However, when subjects were subclassified into non-diabetics and prediabetics, according to glycated hemoglobin (HbA1c) - < 5.7% and 5.7 - 6.4%, respectively - and/or fasting plasma glucose (FPG) - < 100 mg/dL and 100 - 125 mg/dL, respectively -, differences were evident. Prediabetics in the mazindol-metformin group had a higher rate of 7% weight reduction (78.4%, n = 37) compared to prediabetics treated with mazindol (48.3%, n = 29). Furthermore, mazindol-metformin treatment induced significant reductions in fasting plasma insulin, HOMA-IR, and HbA1c in prediabetics compared to mazindol. No differences were found in any parameter between non-diabetics treated with mazindol (n = 36) and mazindol-metformin (n = 35). CONCLUSION: Our results highlight the effectiveness of mazindol-metformin to achieve higher rates of 7% weight reduction and to improve the glycemic profile in prediabetic obese subjects, which could be useful to prevent or delay T2D in these subjects.

Efficacy and safety of a fixed-dose combination of D-norpseudoephedrine, triiodothyronine, atropine, aloin, and diazepam in obese patients
.

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) ˃ 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 ˃ obese grade 1 ˃ 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.
