Actonel (Risedronate)
The bisphosphonates are a group of drugs that are very good at building up bone. They have been tested in both men and women. As a group, the bisphosphonates are poorly absorbed. They need to be taken on an empty stomach in order to ensure the best absorption. After absorption, they bind tightly to the bone cells, slowing down bone loss and allowing your bone-building cells to increase your bone density.

Actonel is a very similar medication to Fosamax. Like Fosamax, it is not very well absorbed so it should be taken on an empty stomach. The dose for Actonel is 5 milligrams (mg) per day or 35 mg once a week. Actonel is generally well tolerated and has been shown to increase bone density at both the spine and hip.
