Problems solved by technology

[0003] In transdermal preparations, such as sprays, solutions, lotions, ointments, films, gels, etc., there are certain disadvantages: that is, it may cause drug loss when the patient rubs, and it is easy to contaminate the patient's clothing , or pollute the exposed population, it is not easy to clean up; the patch may cause adverse reactions such as allergies or even ulcers due to poor air permeability; the preparation process is cumbersome and requires high preparation equipment, such as vacuum mixer or coating machine, etc.
The reason is that: firstly, it is quite difficult to screen out a matrix (film-forming material, etc.) that can be well compatible with the main active ingredient-steroid hormone drugs, such as severe precipitation of such drugs or poor film properties; secondly, the preparation The poor air permeability or irritation brought by the ingredients makes it poorly tolerated, and adjusting the ingredients may lead to reduced adhesion and drug efficacy

Abstract

The invention relates to a film coating agent containing steroid hormone, which comprises 1 part of steroid hormone medicament, 1-50 parts of film forming materials, 0.5-10 parts of plasticizer, 0.5-10 parts of biological adhesive materials and 1-50 volumes of transdermal enhancer. The preparation of the present invention is capable of raising the efficiency of conveying steroid hormone medicament into the body by permeating skin and improving the irritation to the skin, and has good survivability. The invention also relates to a preparation method of the film coating agent, and the preparation method has the advantages of simple process, convenient operation and less energy consumption.

Description

(1) Technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a coating agent containing steroid hormone drugs and a preparation method thereof. (2) Background technology [0002] Steroid hormones play a definite role in maintaining life, regulating sexual function, developing the body, regulating immunity, treating skin diseases and birth control. When the level of steroid hormones in the body is low or lacking, it will produce very painful syndromes, loss of fertility, serious and even life-threatening. For example, studies have shown that one of the reasons for male hypogonadism or postmenopausal female sexual disorder (HSDD) is due to the lack of androgen. Steroid hormones are often used in hormone replacement therapy or to supplement deficient hormone levels in the body. However, most natural steroid hormones, such as testosterone, are hardly absorbed in the gastrointestinal tract, and oral administration is ineffective...
