Problems solved by technology

[0005] Neolistat has very low solubility in water. EP1897558 discloses that its solubility in water at 37°C does not exceed 10 mg / L. Therefore, when the poorly soluble Neolistat is administered orally, its bioavailability is inevitably low , affecting the efficacy of the drug

Abstract

The invention relates to cetilistat solid dispersion, and a medicinal preparation prepared from the solid dispersion. The cetilistat and one or both of the carriers hydroxypropyl cellulose and copovidone are prepared into a solid dispersion to significantly improve the solubility of the cetilistat, and overcome low solubility of cetilistat, so that the prepared medicinal preparation achieves good dissolution, and has increased bioavailability.

Description

technical field [0001] The invention relates to a solid dispersion of medicine for treating obesity and a pharmaceutical preparation thereof, in particular to a new lixistat solid dispersion and a pharmaceutical preparation thereof. Background technique [0002] Obesity is a chronic disease manifested by excess body fat tissue or an excessively high ratio of adipose tissue to other soft tissues. WHO defines obesity in adults: BMI [body mass index: weight / height squared (kg / m 2 )] at 25-29.9 is overweight, 30 is obese, and 40 is severely obese. With the improvement of living standards, the proportion of obese people in the total population of the society is increasing, and the prevalence of obesity is three times that of 20 years ago. The proportion of obese patients with metabolic syndrome such as diabetic lipid metabolism disorder is as high as 7.68%, and the risk of tumors is also increased. Numerous US and European studies have shown that mortality from obesity varies w...
