Abstract

The invention discloses a pharmaceutical composition of desmopressin acetate, and application of the same to biological medicine. The pharmaceutical composition of desmopressin acetate contains desmopressin acetate and a natural product compound (I) with a novel structure. Individual action of desmopressin acetate or the compound (I) enables the phagocytic function of alveolar macrophages and the vitality of AMPhi endoenzyme to be improved and exerts improvement effect on the immune functions of the lung. Combined action of desmopressin acetate and the compound (I) exerts better improvement effect on the immune functions of the lung, so the pharmaceutical composition can be developed into a drug for improving the immune functions of the lung; and the pharmaceutical composition has outstanding substantive features and substantial progress compared with the prior art.

Description

technical field [0001] The invention belongs to the field of biomedicine and relates to a new application of desmopressin acetate, in particular to a pharmaceutical composition of desmopressin acetate and its application in biomedicine. Background technique [0002] Desmopressin acetate can shorten or normalize the excessive bleeding time during clinical invasive treatment or diagnostic operation, or cause uremia, liver cirrhosis, congenital or drug-induced platelet dysfunction, and unknown etiology The blood phenomenon in patients with prolonged bleeding is under control. This product can be used for the control or prevention of bleeding during minor operations in patients with mild hemophilia A and von Willebrand patients who have a positive response to the test dose. For special cases, it can even be used to treat and prevent patients with moderate illness. [0003] So far, there is no report on the correlation between desmopressin acetate and its pharmaceutical composi...
