For the treatment of Paget's disease of the bone (osteitis deformans), postmenopausal and glucocorticoid-induced osteoporosis
The action of risedronate on bone tissue is based partly on its affinity for hydroxyapatite, which is part of the mineral matrix of bone. Risedronate also targets farnesyl pyrophosphate (FPP) synthase. Nitrogen-containing bisphosphonates (such as pamidronate, alendronate, risedronate, ibandronate and zoledronate) appear to act as analogues of isoprenoid diphosphate lipids, thereby inhibiting FPP synthase, an enzyme in the mevalonate pathway. Inhibition of this enzyme in osteoclasts prevents the biosynthesis of isoprenoid lipids (FPP and GGPP) that are essential for the post-translational farnesylation and geranylgeranylation of small GTPase signalling proteins. This activity inhibits osteoclast activity and reduces bone resorption and turnover. In postmenopausal women, it reduces the elevated rate of bone turnover, leading to, on average, a net gain in bone mass.

Rapid absorption (~1 hr) after an oral dose, occurs throughout the upper gastrointestinal tract
1.5 hours
Risedronate is excreted unchanged primarily via the kidney. Insignificant amounts (<0.1% of intravenous dose) of drug are excreted in the bile in rats.
