Abstract

The invention discloses tannin paste and a preparation method thereof. The paste is composed of the following components in parts by weight: 100 parts of tannin, 150 parts of glycerol, 73.8 parts of lanolin, 664.2 parts of vaseline, 2 parts of anhydrous sodium sulfite and 10 parts of purified water. When the tannin paste is prepared, the vaseline and the lanolin are heated and mixed to form a component A; the purified water, the glycerol and the anhydrous sodium sulfite are heated and mixed to form a component B; and after the component B and the tannin are mixed to obtain a mixture, the mixture is added into the component A to obtain the tannin paste. The anhydrous lanolin in the formula can adsorb free moisture in preparation, so that the stability of products is increased; the tannin paste does not contain anticorrosives and beewax which are replaced by the vaseline and the lanolin which are easily smeared, so that the softness of the preparation is improved, and the tannin paste is easily smeared; in the preparation process of the tannin paste, materials are easily blocked, according to the preparation method provided by the invention, after a little water is added, the solubility is improved; and through an extracorporeal drug release test, the drug release performance is better than that of a preparation prepared by a national standard prescription.

Description

technical field [0001] The invention belongs to the technical field of medicine and its preparation, in particular to the field of medicine suitable for skin diseases of infants and its preparation, in particular to a tannic acid ointment and its preparation method. Background technique [0002] Tannic acid (also known as tannic acid) is a kind of tannin extracted from gallnuts, which is a yellow or light brown light-weight amorphous powder or scale substance. It is easily soluble in water and ethanol, and also easily soluble in glycerin. Tannic acid has astringent effect: because the tannic acid contained in it has a precipitation effect on protein, after the skin, mucous membranes, and ulcers are exposed to tannic acid, the tissue protein will be coagulated, forming a film and showing astringent effect. At the same time, small blood vessels are also blocked. Compression and contraction, blood coagulation and hemostatic effect; glandular cell protein coagulation causes secr...
