BACKGROUND: Orlistat is a gastrointestinal lipase inhibitor approved for use in obesity. So far, no evidence has been reported on the use of orlistat in obese patients with coronary artery disease (CAD). AIM: To investigate the effect of orlistat on body weight and lipid profiles in obese patients with CAD and hypercholesterolemia. METHODS: Thirty non-diabetic patients with CAD, body mass index (BMI) > or = 25 kg/m(2) and low-density lipoprotein cholesterol (LDL-C) > or = 2.6 and < 4.1 mmol/L were put on diet for 12 weeks. Those still having a BMI > or = 25 kg/m(2) received orlistat 120 mg thrice daily for another 24 weeks. RESULTS: BMI was significantly reduced by 1.7% after 12 weeks of dietary treatment. The 24-week orlistat treatment resulted in further significant reduction in BMI (-2.8%) and LDL-C (-7.0%). CONCLUSION: Diet and orlistat treatment significantly reduced BMI and improved LDL-C in obese patients with CAD and hypercholesterolemia.
