简要总结
The prevalence of obesity is increasing worldwide and obesity is an important risk factor for cardiovascular disease. In addition, back pain has been increasing steadily due to sitting life, lack of exercise, wrong posture, and obesity. Recent studies found that obesity and back pain are common diseases and are closely related to each other. People with back pain have lower physical activity, which in turn leads to an weight gain and a deterioration in physical performance. Among the drugs used for obesity, orlistat has been approved for long-term use, and phentermine, the most commonly used drug, has been approved for short-term use. However, phentermine can increase blood pressure and pulse rate. Meanwhile, several studies have shown that orlistat, a pancreatic lipase inhibitor, lowers blood pressure and pulse rate and diminish LDL-cholesterol. Lowering LDL-C could lead to improved vascular endothelial function.
The investigators aimed to investigate the effect of orlistat and phentermine combination therapy on weight loss and improvement of vascular function compared to phentermine monotherapy in obese patients (BMI 27 kg/m2) with metabolic risk and back pain.
详细描述
The investigators aimed to investigate the effect of orlistat and phentermine combination therapy on weight loss and improvement of vascular function compared to phentermine monotherapy in obese patients (BMI 27 kg/m2) with metabolic risk and back pain.
Randomized placebo-controlled clinical trials (12 weeks), Patients: Obese patients (BMI 27 kg/m2) with metabolic risk and back pain
The patients were divided into two groups: orlistat (120mg, three times a day), phentermine (37.5 mg, once a day) combined Group (N = 57), placebo (placebo, three times a day) and phentermine (37.5 mg, once a day) Group (N=57).
Randomly assigned to each group at 1: 1, and allocation codes are generated using SAS (Ver. 9.2). The investigators provide orlistat and phentermine or placebo and phentermine. The investigators check physical measurement, blood test, questionnaire, blood pressure and pulse, body composition, FMD, heart rate variability test, in the first visit. The investigators check for changes in body weight, compliance, and side effects after 4 weeks and 8 weeks, respectively. After 12 weeks, the investigators re-check physical measurement, blood test, questionnaire, blood pressure and pulse, body composition, FMD, heart rate variability test.
