The invention relates to the technical field of medicine, in particular to a brazilin-containing pharmaceutical composition and a preparation method and application thereof, and preparation raw materials comprise brazilin and a zinc preparation. Through the synergistic effect of the brazilin and the zinc preparation, the fibrosis area after myocardial infarction can be remarkably reduced, the cardiac function after myocardial infarction can be improved, and the cardiac fibrosis degree can be effectively relieved by inhibiting the expression of fibrosis-related genes and proteins at transcription and protein levels.

A formulation for treating incontinence-associated dermatitis or other skin conditions includes zinc oxide as an active pharmaceutical ingredient, a starch as a rheology modifier, a preservative or preservative system, an emulsifier, an emollient, and a water solvent. An applicator for applying a formulation to an affected area on a patient includes a sheet of a cloth material. The sheet is non-permeable such that a first side of the sheet is provided with the zinc oxide formulation and a second opposite side of the sheet is not exposed to the zinc oxide formulation.

The invention relates to the technical field of pharmaceutical analysis, and discloses a method for determining the zinc content in a calcium zinc gluconate preparation. The determination method comprises the following steps: reacting a calcium zinc gluconate preparation with a complexing agent to obtain a zinc ion-complex; determining the absorbance of the zinc ion-complex by using an ultraviolet-visible spectrophotometric method; and calculating the zinc content based on the standard curve. According to the determination method provided by the invention, the complexation reaction and the ultraviolet spectrophotometry are combined, the zinc content in the calcium zinc gluconate preparation is calculated by the standard curve, the result accuracy is high, and the defect that the determination result is inaccurate due to the reason that an end point is subjectively judged by virtue of color and the like in an EDTA titration method is overcome; the complexing agent [o-[2-(2-hydroxy-5-sulfo-phenylazo) benzal] hydrazinobenzoic acid and xylenol orange are only complexed with zinc ions under a specific pH condition, so that the specificity is high, and the interference of other raw and auxiliary materials in the calcium zinc gluconate preparation can be avoided.
