Senile osteoporosis is a common and frequently occurring disease of the elderly, especially women after menopause. Therefore, attention and importance are also drawn to medicaments for osteoporosis treatment.
Bisphosphonate drugs are new drugs developed in the last twenty years, and have paid attention to the prevention and treatment of senile osteoporosis abroad, and the bisphosphonate drugs have the following characteristics in clinic: (1) not only can inhibit bone resorption, but also can increase bone mass to recover lost bone tissue; (2) can promote the reconstruction of trabeculae and reduce the depth of absorption pit; (3) short-term administration and long-term effect. In addition, bisphosphonates are first-line therapeutic agents for hypercalcemia caused by malignant tumors and paget's disease of bone.
The alendronate sodium is created by Italy Instituto Gentili company, is marketed under the trade name Alendros in Italy in 1993, is marketed under the name Fosamax in 1995, is used for treating osteoporosis and osteoarthritis, and is approved again by FDA in 5 months in 1997 to prevent osteoporosis and prevent the expansion indication of fracture, so that the alendronate sodium becomes a non-hormone medicament approved by FDA for preventing osteoporosis for the first time, has the weight gain effect on bones similar to estrogen, is superior to calcitonin, can obviously increase bone density, reduces the occurrence rate of fracture, is orally effective, has lasting effect, and has good tolerance and higher safety.
