The potential effect of orlistat on cardiovascular co-morbidities may have been previously underestimated. This study assesses the efficacy of orlistat therapy for weight loss and cardiovascular risk factor reduction in obese patients with cardiovascular risk. This was a 54-week, double-blind, randomised, placebo-controlled, parallel group study with 531 patients being randomised. Mean weight loss was significantly greater with orlistat than with placebo (5.8% vs 2.3%; p<0.0001). Orlistat was also associated with significantly greater improvements than placebo in diastolic BP (-5.5 vs -3.1 mmHg; p<0.01), systolic blood pressure (-6.0 vs -2.3 mmHg; p<0.01), oral glucose tolerance test (-0.37 vs +0.09 mmol/l; p<0.05), fasting glucose (-0.19 vs +0.06 mmol/l; p<0.05), total cholesterol (-1.31% vs +3.78%; p<0.0001), LDL-cholesterol (-7.09% vs -0.55%; p<0.0001) and waist circumference (-5.99 vs -2.60 cm; p<0.0001). Orlistat was well tolerated. Orlistat weight loss is associated with improvements in cardiovascular co-morbidities, and hence cardiovascular risk.
