Risedronic acid is not likely not metabolized before elimination. The P-C-P group of bisphosphonates is resistant to chemical and enzymatic hydrolysis preventing metabolism of the molecule.

代谢
没有证据表明瑞斯德隆酸盐在人类或动物体内被代谢。/瑞斯德隆酸盐/
There is no evidence that risedronate is metabolized in humans or animals. /Risedronate/
No evidence found for metabolization of risedronate in humans or mammals.
Route of Elimination: Risedronate is excreted unchanged primarily via the kidney. Insignificant amounts (<0.1% of intravenous dose) of drug are excreted in the bile in rats.
Half Life: 1.5 hours
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.
Oral bioavailability is 0.63% and maximum absorption is approximately 1 hour after dosing. Administration half and hour before a meal reduces bioavailability by 55% compared to fasting and dosing 1 hour before a meal reduces bioavailability by 30%.

/Absorption is/ rapid and independent of dose, occurring throughout the upper gastrointestinal tract. Mean oral bioavailability is 0.63% and is decreased when administered with food. Administration either 0.5 hour before breakfast or 2 hours after dinner reduces the extent of absorption by 55% compared to the fasting state (no food or drink for 10 hours before or 4 hours after administration). Administration 1 hour before breakfast reduces the extent of absorption by 30% compared with the fasting state. /Risedronate/
