lasofoxifene (tartrate) is a third-generation, nonsteroidal selective estrogen receptor modulator (serm).estrogen receptors are activated by the hormone estrogen (17β-estradiol). serms are characterized by having estrogen agonist action in some tissues while acting as estrogen antagonists in others [1][2].lasofoxifene, also known as cp 336,156, is a third-generation, nonsteroidal selective estrogen receptor modulator. lasofoxifene bound with high affinity to the human estrogen receptor-α with ic50 value of 1.5 nm [1]. lasofoxifene is also a cb2 inverse agonist [4].in aged female rats, lasofoxifene decreased total serum cholesterol and fat body mass, and no uterine hypertrophy was observed. in 5-month-old ovariectomized (ovx) sprague-dawley female rats, lasofoxifene completely prevented ovx-induced increases in body weight gain, total serum cholesterol, and serum osteocalcin. cp-336,156 completely prevented ovx-induced bone loss and inhibited the increased bone turnover associated with estrogen deficiency in lumbar vertebrae, proximal tibiae, and distal femora [1].in postmenopausal women with osteoporosis, lasofoxifene reduced risks of nonvertebral and vertebral fractures, er-positive breast cancer, coronary heart disease, and stroke but an increased risk of venous thromboembolic events [2][3]. | [Biochem/physiol Actions]
