Abstract

The invention discloses an orally disintegrating tablet of 'Shengmai' and its preparation characterized in that the tablet comprises the significant portions extracted from traditional Chinese medicinal panax ginseng, ophiopogon root, schisandra fruit and other medical use findings, the invention is also characterized that composite disintegrating tablet containing tetrahydroxy butane is employed, wherein the composite disintegrating tablet is obtained by combining tetrahydroxy butane with low substituted Hydroxypropylmethyl cellulose or sodium carboxymethylstarch or crossbond sodium carboxymethylstarch or insoluble cross bond polyvinylpyrrolidone by a finite proportion, the tetrahydroxy butane has the action of taste rectifying agent, thus reducing the consumption of medicinal findings in the preparation. Pharmacological experiment has shown that the disintegrating tablet has the advantages of quick disintegration, fast effect, and better pharmacological actions.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine pharmacy, and in particular relates to a Shengmai orally disintegrating tablet and a preparation method thereof. Background technique [0002] Orally disintegrating tablets are a new pharmaceutical preparation, which can be absorbed through the sublingual mucosa and directly enter the blood, effectively avoiding the first-pass effect, so the dosage is small, safe and has a rapid effect. Although it is an oral preparation, it can achieve the effect of an injection preparation. Therefore, it is gradually becoming a hot spot in the field of pharmaceutical companies and research and development. The dosage form is mainly to select a suitable fast disintegrating agent, and the tablet made of it has a certain hardness and a certain degree of porosity. When taking it, it does not need water to assist swallowing, and it can quickly disintegrate into fine particles in the mouth, and ...
