n3:description
Ibandronate is a nitrogen-containing bisphosphonate in the same class as alendronate and risedronate. Ibandronate inhibits osteoclast-mediated bone resorption. All of the bisphosphonates prevent the breakdown of bone by bone cells called osteoclasts. In persons who are at high risk for osteoporosis, bisphosphonates not only result in increased amounts of bone and bone strength, they also reduce the risk of hip fractures and other bone fractures.

n3:mechanismOfAction
The action of ibandronate on bone tissue is based partly on its affinity for hydroxyapatite, which is part of the mineral matrix of bone. Nitrogen-containing bisphosphonates (such as pamidronate, alendronate, risedronate, ibandronate and zoledronate) appear to act as analogues of isoprenoid diphosphate lipids, thereby inhibiting farnesyl pyrophosphate (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.

n3:routeOfElimination
Ibandronate is eliminated by renal excretion. Unabsorbed ibandronate is eliminated unchanged in the feces.
n3:synonym

n3:toxicity
LD<sub>50</sub> = 811 mg/kg (rat, oral), side effects include bronchitis, pneumonia and urinary tract infections.

n3:foodInteraction
Take on an empty stomach. All foods markedly reduce (up to 90%) ibandronate bioavailabilty. Take with plain water (not mineralized) at least 1 hour before any food. Bioavailability and effect on bone density are both impaired if the patient eats or drinks in less than 1 hour after taking this product. Drink a large glass of water and stay in an upright position for at least 60 minutes after taking this product.
