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
