Bondenza can be given either as a tablet or as an injection into a vein. If the tablet is used, the dose is one tablet every month, preferably on the same date each month. The tablet must always be taken after an overnight fast, one hour before any food or drink except for water, and with a full glass of plain water. (In areas with hard water, where tap water contains a lot of dissolved calcium, bottled water with a low mineral content may be used.) The patient must not lie down for one hour after taking the tablet. The dose by injection is 3 mg once every three months. Patients taking Bondenza should also take vitamin D and calcium supplements if they do not get enough from their diet.

How does Bondenza work?
Osteoporosis happens when not enough new bone grows to replace the bone that is naturally broken down. Gradually, the bones become thin and fragile, and more likely to break. Osteoporosis is more common in women after the menopause, when the levels of the female hormone oestrogen fall, since oestrogen helps to keep bones healthy.
The active substance in Bondenza, ibandronic acid, is a bisphosphonate. It stops the action of the osteoclasts, the cells that are involved in breaking down the bone tissue. Blocking the action of these cells leads to less bone loss.
How has Bondenza been studied?
Bondenza has been studied in three main studies involving women with osteoporosis. The first study
The other two studies compared the 150-mg monthly tablets (1,609 patients) and the injections (1,395 patients) with the 2.5-mg once-daily tablets. The studies looked at the change in the density of the bones in the spine and the hip over two years.
