  <description>Risedronate belongs to the bisphosphonates, a subclass of organic phosphonic acids and derivatives within the organic compounds. It is an exogenous solid with the formula C7H11NO7P2 and an average molecular weight of 283.11 g/mol. This biological drug (PMC10692760, PMC8713161) is administered via the oral exposure route and is used in healthcare, pharmaceuticals, and veterinary products for the treatment of bone diseases.

The compound targets geranylgeranyl pyrophosphate synthase (GGPS1) and farnesyl pyrophosphate (FPP) synthase. The action of risedronate on bone tissue is based partly on its affinity for hydroxyapatite, which is part of the mineral matrix of bone. As a nitrogen-containing bisphosphonate, risedronate acts as an analogue of isoprenoid diphosphate lipids to inhibit FPP synthase, an enzyme in the mevalonate pathway. This inhibition in osteoclasts prevents the biosynthesis of isoprenoid lipids, thereby inhibiting osteoclast activity and reducing bone resorption and turnover.

Risedronate is used as a treatment for osteoporosis (PMC10547673, PMC10889292, PMC11012270, PMC2686344, PMC2971711, PMC3010171, PMC3079953), hypercalcemia (PMC10547673), multiple myeloma (PMC10547673), and glucocorticoid-induced osteoporosis (PMC5114204, PMC6924235). It has a therapeutic effect on breast cancer (PMC6607035) and glucocorticoid-induced osteoporosis (PMC2686344). Associated health effects include nausea (PMC2879572), headache (PMC6924235), and an increase in fever (PMC2971711), while it is associated with a decrease in necrosis (PMC10871045) and esophageal cancer (PMC10871045).</description>

  <mechanism_of_toxicity>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.</mechanism_of_toxicity>
  <metabolism>No evidence found for metabolization of risedronate in humans or mammals.&#13;Route of Elimination: Risedronate is excreted unchanged primarily via the kidney. Insignificant amounts (&lt;0.1% of intravenous dose) of drug are excreted in the bile in rats.&#13;Half Life: 1.5 hours</metabolism>
