Comparación de las Clases de Medicamentos Antirresortivos

La siguiente tabla compara los LOS Neisseria mecanismos de acción y los LOS Neisseria efectos secundarios de las clases de medicamentos utilizados para controlar y/o prevenir la osteoporosis Osteoporosis Osteoporosis refers to a decrease in bone mass and density leading to an increased number of fractures. There are 2 forms of osteoporosis: primary, which is commonly postmenopausal or senile; and secondary, which is a manifestation of immobilization, underlying medical disorders, or long-term use of certain medications. Osteoporosis:
