Abstract

The invention discloses a skin external-use patch containing a calcium-sensing receptor stimulant. For the patch disclosed by the invention, a medicinal storage layer, a backing layer and a protection layer are adopted as the necessary ingredients of the patch, and meanwhile, other pharmaceutically acceptable excipients also can be added. The patch is administrated through the skin, so that the first-pass effect of the liver and the stimulation to the gastrointestinal tract are avoided, the untoward effects of the medicines are effectively reduced, the medication to patients is safe, meanwhile, compared with the tablets for oral administration, the patch provided by the invention has the permanent efficacies, and the bioavailability is obviously improved.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and mainly relates to an external skin patch containing a calcium sensitive receptor agonist and a preparation method thereof. Background technique [0002] Secondary hyperparathyroidism (SHPT) is a common complication of chronic kidney disease (CKD), and its prevalence increases with the progression of CKD. It mainly leads to abnormal mineral and bone metabolism in patients. In recent years, it has been recognized that its severity mainly leads to cardiovascular calcification, which is closely related to the survival and prognosis of dialysis patients. Active vitamin D drugs have been used in the clinical treatment of SHPT for nearly 30 years, because the treatment is often accompanied by hypercalcemia and hyperphosphatemia, which increases the risk of cardiovascular calcification and thus limits its clinical application. Most patients with SHPT who are ineffective in drug therapy can...
