Description: Risedronate, also known as NE-58095, often used as its sodium salt risedronate sodium (USAN), is a bisphosphonate used to strengthen bone, treat or prevent osteoporosis, and treat Paget's disease of bone. Like other bisphosphonates, it inhibits bone resorption. In addition, it has antimalarial activity and inhibits growth of P. falciparum in vitro (IC50 = 20.3 µM) and P. berghei in vivo.
