Problems solved by technology

The most commonly used formulation for transdermal drug delivery is a patch, which is easy to use and has a relatively simple preparation process, but the drug loading of the patch is small and the gas permeability is poor, and most patients will have allergic reactions
With the continuous development of the preparation process, the gel ointment has attracted more and more attention. The gel ointment has a large drug loading capacity, its water content is as high as 40%-70%, and it has good air permeability. It will not cause allergies after long-term use. Good compliance, but due to its technical difficulty, so far there is no report on the relevant information about Xi'an Kasai Hydrochloride Gel Cream

Abstract

The invention discloses a skin external use preparation containing a calcium receptor activity compound. The preparation avoids hepatic first pass effect and gastrointestinal adverse reactions of an oral preparation. The preparation comprises a medicine active component, a high-molecular gel skeleton, a tackifier, a moisturizer, and other pharmaceutically acceptable excipients. The preparation has high drug load and is free of problems of irritation and allergy, has no crystallization phenomenon, has better stability and is more safe and convenient to use.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to an external skin preparation containing a calcium receptor active compound. Background technique [0002] Secondary hyperparathyroidism (SHPT) is a common complication of chronic kidney disease (CKD). Chronic kidney disease leads to abnormal mineral and bone metabolism in patients, and its severity mainly leads to cardiovascular calcification. closely related to survival. Active vitamin D drugs used in the clinical treatment of secondary hyperparathyroidism are often accompanied by hypercalcemia and hyperphosphatemia, which increase the risk of cardiovascular calcification. Most patients with secondary hyperparathyroidism who do not respond to medical treatment can only receive parathyroidectomy. The advent of calcium receptor active compounds has changed the risk of surgery in patients with secondary hyperparathyroidism, making most patients with severe secondary hyp...
