Problems solved by technology
However, we found that such preparations are either directly neutralized by acid and base, causing the preparation to be very unstable, or the base of the outer layer is neutralized by the acidic environment of the vagina, and it cannot prevent the ingredients in the inner layer of particles from diffusing to the outer layer and Neutralization, not only the preparation is unstable, but also the efficiency of releasing the active ingredient is very low, and the alkali in the outer layer may even bring a certain stimulating effect to the human body. These restrictive factors have led to the fact that this technology has not been practically applied and promoted so far.
Chinese patent application 200410013177.1 involves the compound preparation of matrine and borneol. The increase of active ingredients will bring geometric progression to the difficulty of production quality management, which greatly increases the production cost, and the patent does not specifically involve the innovation of the preparation
However, we found that on the one hand, such preparations have complex adjuvant components and require a precision of 30 mesh sieves, which greatly increases the production cost and the difficulty of production quality management; more importantly, because the human vagina is not a pure fluid environment, part of it The disintegrated alkaline granules will not touch the acidic granules but directly contact with the vagina, and even cause local alkalinity, while the acidic granules will even persist in the vaginal environment for a long time due to the presence of the adhesive, which will cause adverse effects on the vagina. Irritation to the human body, and because the acid in the tablet itself is not fully utilized, the release efficiency and uniformity are reduced, sometimes it is impossible to form a continuous foam, and it is even difficult to achieve the curative effect of the existing matrine suppository. Restricting factors lead to the fact that the technology has not been practically applied and promoted so far
