Piridronic acid is pyridinyl bisphosphonate. It is the bone calcium metabolism regulator. Piridronic acid was used for the treatment of osteoporosis. It is the human farnesyl pyrophosphate synthase inhibitor. When expressed on an actual or anticipated clinical dose basis for osteoporosis piridronic acid may have a greater potential for inducing gastric damage than do pyridinyl bisphosphonates. Piridronic acid induced significantly more antral damage than risedronate and a greater number of lesions compared to pamidronate and risedronate.
