 |  | [Uses] 
 Risedronic Acid is a pyridinyl biphosphonate bone resorption inhibitor.
 |  | [Definition] 
 ChEBI: Risedronate sodium is a 1,1-bis(phosphonic acid).
 |  | [Brand name] 
 Actonel (Procter & Gamble).
 |  | [Biological Activity] 
 Orally  active  biphosphonate  that  inhibits  farnesyl  diphosphate  (FPP)  synthase.  Exhibits  antiproliferative  and  proapoptotic  activity  in  numerous  tumor  cell  lines  and  inhibits  osteoclast-mediated  bone  reabsorption in  vivo  .
 |  | [Biochem/physiol Actions] 
 Risedronate sodium is a bisphosphonate bone resorption inhibitor.  It has an affinity for hydroxyapatite crystals in bone and acts as an antiresorptive agent and is  an inhibitor of farnesyl diphosphate (FPP) synthase, which results in downstream inhibition of osteoclast activity and reduced bone resorption and turnover.  Risedronate sodium has been used to treat postmenopausal osteoporosis and Paget′s disease.
 |  | [Clinical Use] 
 Bisphosphonate:
 Treatment and prevention of osteoporosis (including 
corticosteroid induced)
 Paget’s disease
 |  | [Drug interactions] 
 Potentially hazardous interactions with other drugs
 Calcium-containing substances: avoid for 2 hours 
before and after administration.
 |  | [Metabolism] 
 The mean bioavailability of risedronate is 0.63% in 
the fasting state, and there is no evidence of systemic 
metabolism of risedronate sodium.
 About half of the absorbed portion is excreted in the 
urine within 24 hours; the remainder is sequestered 
to bone for a prolonged period. Unabsorbed drug is 
eliminated unchanged in the faeces.
 |  | [storage] 
 Store at -20°C

 | Questions And Answer | Back Directory |  | [Description] 
 Risedronate sodium is a nitrogen-containing bisphosphonate that inhibits osteoclast-mediated bone resorption and modulates bone metabolism.
 Risedronate sodium is used for the treatment of postmenopausal osteoporosis to reduce the risk of vertebral fractures, treatment of established postmenopausal osteoporosis to reduce the risk of hip fractures, treatment of osteoporosis in men at high risk of fractures, and treatment of Paget’s disease. It is marketed as Actonel (tablet) and Atelvia (delayed-release tablet).
