应用
Calcium carbonate has been utilized by plants and animal for the formation of their skeletons and shells. It also facilitates the calcium carbonate crystal growth on a chitosan substrate.
生化/生理作用
Calcium carbonate is a naturally occurring compound that reduces T4 absorption and enhancess serum thyrotropin levels. It also precludes osteoporosis induced by thyrotropin-suppressive doses of levothyroxine in postmenopausal women. Additionally, it reduces diarrhea in individuals with protease inhibitor-induced HIV-infection.

Although some evidence exists to support the practice of using calcium carbonate to treat nelfinavir-induced diarrhea, there is a lack of data supporting the role of calcium in diarrhea induced by other protease inhibitors (PIs). The objective of this prospective

The effect of calcium carbonate on the absorption of levothyroxine has not been studied systematically. Such a potential drug interaction merits investigation because concurrent treatment with both drugs is common, particularly in postmenopausal women. To investigate the potential interference of
