Description: Abaloparatide (brand name Tymlos) is a parathyroid hormone-related protein (PTHrP) analog drug used to treat osteoporosis. Like the related drug teriparatide, and unlike bisphosphonates, it is an anabolic (i.e., bone growing) agent. In 2017, it was approved to treat postmenopausal osteoporosis in the United States.
