Prepared from capsule shell liquid and capsule contents; wherein, the capsule contents include: alfacalcidol, medium-chain triglycerides, ascorbyl palmitate, gliadin, polyethylene glycol, phospholipids , monoglyceride laurate; the components of the capsule shell liquid include: gelatin, glycerin, water, ethylparaben, sodium alginate, and chitosan. The preparation method is simple, and the prepared alfacalcidol soft capsules have good stability and bioavailability, and are suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of medicine preparation, and in particular relates to an alfacalcidol soft capsule and a preparation method thereof. Background technique [0002] Alfacalcidol (Alfacalcidol) is a calcitriol analogue, which only needs to be hydroxylated in the liver to become active 1α, 25-(OH)2D3. It can increase the reabsorption of calcium in the small intestine and renal tubules, inhibit parathyroid hyperplasia, reduce the synthesis and release of parathyroid hormone, and inhibit bone resorption; increase transforming growth factor-B (TGF-B) and insulin-like growth factor-I ( 1GF-I) synthesis, promote collagen and bone matrix protein synthesis; regulate muscle calcium metabolism, promote muscle cell differentiation, enhance muscle strength, increase neuromuscular coordination, and reduce the tendency to fall. Alfacalcidol plays a role in regulating the balance of calcium and phosphorus in the human body, and can increase...
