當人體攝入脂肪類食物,體內的解脂酶(lipase)會將脂肪分解成脂肪酸及甘油,解脂酶的水解過程是脂肪分解的決定步驟。Orlistat即是腸道及胰臟所分泌的解脂酶抑制劑,Orlistat會與胃及胰臟解脂酶活性部位之絲氨酸(serine residue)共價結合,藉以干擾lipase分解脂肪,使飲食中脂肪有30%未經消化即排出體外,故身體便無法利用這些脂肪作為能量來源,進而達到控制體重的效果。

Orlistat is a drug designed to treat obesity. Its primary function is preventing the absorption of fats from the human diet by acting as a lipase inhibitor, thereby reducing caloric intake. It is intended for use in conjunction with a healthcare provider-supervised reduced-calorie diet.
