[Combination and sequential therapy using bisphosphonates.].

Bisphosphonates have been explored possible combination and/or sequential use with other anti-osteoporotic medications including PTH. Besides with vitamin D(metabolites), combination treatment had been uncommon mainly because there had not been enough anti-fracture evidence. PTH, which can only be used for a certain period over lifetime, requires other anti-osteoporotic medications after and/or before its use. Bisphosphonates have been tried with PTH in various sequential and/or combination ways. Various combination and/or sequential therapy using bisphosphonates will be reviewed in this article.
