Embodiment 1

[0033] The transdermal patch described in this embodiment is an adhesive skeleton type patch, which is composed of a three-layer structure of a backing layer, a protective layer and a drug-containing adhesive skeleton (that is, a drug reservoir). The materials used in each layer are as follows:

[0034] Backing layer: non-woven fabric

[0035] Protective layer: siliconized paper

[0036] Medicated Adhesive Skeleton: The formula is as follows (100 sticks):

[0037] Acrylic Pressure Sensitive Adhesive 35g

[0038] Coconut 2.5g

[0039] Azone 1.5g

[0040] Preparation process: take the formula amount of fenugreek, acrylate pressure-sensitive adhesive and Azone, add an appropriate amount of ethyl acetate to dissolve, adjust to a suitable consistency, coat on the protective layer, and control the thickness of the coating. Dry at 70°C, cover with a backing layer, and cut into appropriate shapes and sizes.

Embodiment 2

[0042] The transdermal patch described in this embodiment is an adhesive skeleton type patch, which is composed of a three-layer structure of a backing layer, a protective layer and a drug-containing adhesive skeleton (that is, a drug reservoir). The materials used in each layer are as follows:

[0043] Backing layer: non-woven fabric

[0044] Protective layer: polyester film

[0045] Drug-containing adhesive skeleton: the formula is as follows (100 stickers):

[0046] Polyacrylic resin pressure sensitive adhesive 30g

[0047] Aconitine 2g

[0048] Oleic acid 2g

[0049] The formula of polyacrylic resin pressure sensitive adhesive is:

[0050] Polyacrylic resin IV 20g

[0051] Succinic acid 1g

[0052] Dibutyl phthalate 10g

[0053] Acetone 80ml

[0054] Preparation Process:

[0055] 1. Preparation of polyacrylic resin pressure-sensitive adhesive: Dissolve the amount of succinic acid in acetone, then add polyacrylic acid resin and stir to dissolve, and finally add dibut...

Embodiment 3

[0058] The transdermal patch described in this example is an adhesive layer rate-limiting patch, which consists of a backing layer, a protective layer, a drug-containing adhesive skeleton (i.e. drug storage), and a four-layer structure of the adhesive layer. The materials are as follows:

[0059] Backing layer: polyester film

[0060] Protective layer: PTFE film

[0061] Adhesive layer: blank silicone pressure sensitive adhesive

[0062] Drug-containing viscose skeleton: the formula is as follows (100 stickers):

[0063] Silicone pressure sensitive adhesive 30g

[0064] Aconitine 1.0g

[0065] Azone 1.5g

[0066] Preparation Process:

[0067] 1. Preparation of drug-containing skeleton layer: Dissolve silicone pressure-sensitive adhesive, aconitin and Azone in an appropriate amount of ethyl acetate, adjust to a suitable consistency, and coat on the backing layer to control the coating thickness. Dry at 70°C.

[0068] 2. Preparation of adhesive layer: apply blank silicon...

Abstract

The present invention relates to a medicine plaster for external application, in particular, it is a transdermal plaster containing caowujiasu. Said plaster has medicine storage unit, back-lining layer and protecting layer. Said medicine storage unit is formed from caowujiasu and storage matrix, every plaster contains 0.1mg-100 mg of caowujiasu, and the rest is storage matrix. The medicine-releasing area of said plaster is 1 sq.cm-100 sq.cm, and the transdermal speed rate is 0.05 microgram/h.sq.cm, and its continuous medicine-releasing time is 1-12 days. Its theapeutic effect is reliable, quality is stable and convenient in application.

Description

technical field [0001] The present invention relates to a medicinal patch for external use, in particular to a transdermal patch containing clathrin. Background technique [0002] Bulleyaconitione A, molecular formula C 35 H 49 O 10 N, molecular weight 643.77, colorless prismatic crystal. Soluble in ether, alcohol, acid water, insoluble in water, has strong analgesic and obvious anti-inflammatory effect. Experiments have shown that the analgesic effect of this product is central and is closely related to the level of serotonin in the brain. Non-addictive. Its anti-inflammatory effect does not pass through the adrenal system, but is related to the inhibition of PG levels; this product has antipyretic and local anesthetic effects. There were no abnormal changes in the patients' ECG, EEG, liver and kidney function and urine routine examination after treatment compared with those before treatment. Clinically, this product has good curative effect on rheumatoid arthritis, ...
