Is there a difference between Gai Sanchun of Qingdao Haier Pharmaceutical Co., Ltd. and Alfacalcidol Soft Capsule (Yandino) of Shanghai Xinyi Yan 'an Pharmaceutical Co., Ltd. in the treatment of osteoporosis? Alfacalcidol and gaitriol are both active VD and basic drugs for the treatment of osteoporosis, but their active forms are different. After taking alfacalcidol, the blood concentration is relatively stable, which can be understood as safer, but routine taking calcitriol will not have big adverse reactions, so there is little difference between the two.
