描述奥利司他 用于治疗肥胖。用奥利司他实现的减肥量变化。在一年的临床试验中,在35.5%和54.8%之间的受试者实现了5%或更大的体重下降,尽管不是所有的这一质量都必然是脂肪。在16.4%和24.8%之间实现了至少10%的体重下降。在停用奥利司他后,大量的受试者恢复了体重 - 高达他们失去的体重的35%。
与安慰剂(9.0%)相比,奥利司他在4年内的肥胖人群中2型糖尿病的发生率降低(6.2%)。长期使用奥利司他还导致血压的适度降低(分别在收缩压和舒张压下平均降低2.5和1.9mmHg)。

DescriptionsOrlistat is used for the treatment of obesity. The amount of weight loss achieved with orlistat varies. In one year clinical trials, between 35.5% and 54.8% of subjects achieved a 5% or greater decrease in body mass, although not all of this mass was necessarily fat. Between 16.4% and 24.8% achieved at least a 10% decrease in body mass. After orlistat was stopped, a significant number of subjects regained weight- Up to 35% of the weight they had lost.
The incidence of type 2 diabetes in an obese population over four years is decreased with orlistat (6.2%) compared to placebo (9.0%). Long-term use of orlistat also leads to a modest reduction in blood pressure (mean reductions of 2.5 and 1.9 mmHg in systolic and diastolic blood pressure respectively).
