Jelaskan Bisphosphonates dari Osteogenesis imperfecta dalam bahasa melayu

Bisphosphonates (BPs), particularly those containing nitrogen, are being increasingly administered to increase bone mass and reduce the incidence of fracture. BPs can be dosed orally (e.g. alendronate) or by intravenous injection/infusion (e.g. pamidronate, zoledronic acid).

BP therapy is being used increasingly for the treatment of OI. It has proven efficiency in reducing fracture rates in children, however only a trend towards decreased fracture was seen in a small randomized study in adults. While decreasing fracture rates, there is some concern that prolonged BP treatment may delay the healing of OI fractures, although this has not been conclusively demonstrated.

Pamidronate is used in USA, UK and Canada. Some hospitals, such as most Shriners, provide it to children. Some children are under a study of pamidronate. Marketed under the brand name Aredia, Pamidronate is usually administered as an intravenous infusion, lasting about three hours. The therapy is repeated every three to six months, and lasts for the life of the patient.  Common side effects include bone pain, low calcium levels, nausea, and dizziness. According to recent results, extended periods of pamidrinate, (i.e.;6 years) can actually weaken bones, so patients are recommended to get bone densities every 6 months-1 year, to monitor bone strength.
