Embodiment 1

[0027] Example 1: The blatacine anti-tumor external patch of the present invention includes a backing layer, a drug reservoir and an anti-adhesive layer. A cotton medical non-woven fabric with good air permeability is used as the backing layer and the drug reservoir The polymer gel acrylate pressure-sensitive adhesive is used as the adhesive, containing the formulated blatacine liquid, and the silicone oil anti-sticking treatment polyester film is used as the anti-sticking layer.

[0028] Blatacine medicinal solution is to dissolve 198 grams of blatacine parts in a 1100ml mixture of anhydrous ethanol and propylene glycol with a volume ratio of 1:1, stir well and mix well to make 20400 patches for external use. (Size: 7×10cm).

Embodiment 2

[0029] Example 2: Preparation method of blatacine anti-tumor topical patch, which includes the following steps: (1) Ingredients: dissolve 198 grams of blatacine part medicine in absolute ethanol with a volume ratio of 1:1 In the 1100ml mixture of propylene glycol and propylene glycol, fully stir to make it evenly mixed; (2) Glue preparation: pressure-sensitive adhesive produced by the production process of acrylate pressure-sensitive adhesive; (3) Coating: Blatacine Mix the mixture of high-quality, absolute ethanol and propylene glycol with the pressure-sensitive adhesive after heating and melting, and coat it on the anti-sticking layer, and then cover the backing layer; (4) Slice: Cut into appropriate size (5×7cm) , 7×10cm, 9×12cm and other specifications); dry and cool, sealed and packaged with aluminum-plastic composite film.

Embodiment 3

[0030] Example 3: The following will further illustrate the beneficial effects of the drug of the present invention through drug clinical trials:

Abstract

The invention discloses a Bulataxin anti-tumor external patch, which consists of a back lining, a drug storage and an anti-adhesive layer. Breathable cotton medical non-woven cloth is selected as the back lining, the drug storage takes a macromolecule gel acrylate pressure-sensitive adhesive as an adhesive, containing the mixed Bulataxin solution, a polyester film through silicone oil anti-adhesive treatment is taken as the anti-adhesive layer. The invention not only solves the shortcomings of significant toxicity and side effects of oral intake or intravenous administration of past anti-tumor drugs, but also overcomes the shortcomings of significant skin irritation and toxicity of traditional external patches and reduces the economic cost.

Description

Technical field [0001] The invention relates to an anti-tumor external administration preparation, in particular to an anti-tumor external patch. Background technique [0002] Annonaceae (Annonaceae) is a large plant population in tropical and subtropical regions. The family contains alkaloids, terpenes, flavonoids, annonaceae, polyoxycyclohexene and styrene lactones. Among them, the last three types of compounds have anti-tumor activity and have aroused widespread interest among scholars from various countries. Annonaceous acetogenins are a new type of natural product first discovered in Annonaceae in 1982. Annonaceous lactone has a wide range of physiological activities, the most typical of which are anti-tumor activity and cytotoxicity. Studies have shown that most of the annona lactone compounds generally have a strong cytotoxic effect on tumor cells cultured in vitro. [0003] At present, the incidence of tumors and cancers worldwide is increasing year by year. Radiation, ch...
