The main purpose of clinical trials that were conducted in Russia in 2009 was to compare the effectiveness of generic Orlistat and original brand Xenical that was more familiar to obese patients.

Krka, the leading generic company from Slovenia, spent 12 weeks studying the difference between Xenical produced by the Swiss company Roche and Krka’s own brand Orsoten, each pill of which contained 120 mg of Orlistat, the chemical substance that was included in Xenical produced by the Swiss company and Alli produced by the American company GlaxoSmithKline.168 patients (both men and women 18+ years old) were divided into two equal groups: Xenical group and Orlistat group. Their weight reduction results are shown in the table below:
