Embodiment 1

[0041] According to the formula (percentage by weight) shown in Table 1, granisetron is first dissolved in the solvent, then the acrylate pressure-sensitive adhesive is added, mixed and stirred evenly to prepare the drug-loaded pressure-sensitive adhesive, and then the usual pressure-sensitive adhesive paste technology is used. Apply the prepared drug-loaded matrix solution to a certain thickness on the plastic film treated with silicone resin, and cover it with a surface film that has not been treated with silicone resin after drying to make a matrix type with a thickness of 0.05 mm. Pressure-sensitive adhesive transdermal preparations.

[0046] SMD number

[0047] (the above table includes saturated fatty acids with carbon atoms of 2, 8, 10, 18, and 20 and unsaturated fatty acids with carbon atoms of 4, 6, and 16) according to the formula (weight percentage) shown in Table 2. Dissolve agar and organic acid in co-solvent, then add acrylate pressure-sensitive adhesive, mix and stir evenly to prepare drug-loaded pressure-sensitive adhesive, and then use the usual pressure-sensitive adhesive paste technique to apply the prepared drug-loaded matrix solution, It is coated with a certain thickness on the plastic film treated with silicone resin, and after drying, it is covered with a surface film that has not been treated with silicone resin to make a matrix-type pressure-sensitive adhesive transdermal drug delivery preparation with a thickness of 0.50 mm.

Embodiment 3

[0049] According to the formula (percentage by weight) shown in Table 3, granisetron and substances other than the pressure-sensitive adhesive durotak87-2677 were first dissolved in the solvent, then the acrylate pressure-sensitive adhesive was added, mixed, and stirred evenly to prepare the drug-loaded pressure-sensitive adhesive. Then use the usual pressure-sensitive adhesive paste technology to apply the prepared drug-loaded matrix solution to a certain thickness on the plastic film treated with silicone resin, and cover it with a surface film that has not been treated with silicone resin after drying , to make a matrix-type pressure-sensitive adhesive transdermal preparation with a thickness of 0.15 mm.

Abstract

The invention relates to a Granisetron and / or a hydrochloride patch thereof, which comprises a lining layer, a medicine carrying pressure sensitive adhesive layer containing the Granisetron or / and the hydrochloride thereof, and an anti-sticking layer, wherein the medicine carrying pressure sensitive adhesive layer is characterized in that pressure sensitive adhesive contains carboxylic groups; the content of the Granisetron or / and the hydrochloride thereof in percentage by weight is 1%-12%; the medicine carrying pressure sensitive adhesive layer contains metal ions capable of enabling the pressure sensitive adhesive to generate cross linking, and the content of the metal ions in the medicine carrying pressure sensitive adhesive layer in percentage by weight is 0.05%-2%; and the medicine carrying pressure sensitive adhesive layer contains organic acids with 2-18 carbon atoms, and the molar ratio of the adding amount of the organic acids to the adding amount of the Granisetron or / and the hydrochloride thereof is (1-5):1. The patch of the invention can obviously increase the percutaneous infiltration capacity of the Granisetron and improve the solvent resistant and ageing resistant action of the substrate, can be applied to preventing and treating the symptoms of nausea, emesis and the like caused by radiotherapy, chemotherapy and operations, and has great foreseeable economic value and social value.

Description

technical field [0001] The present invention relates to the technical field of medicine, and in particular provides a 5-HT 3 A transdermal delivery system for receptor antagonist granisetron and / or its hydrochloride, specifically granisetron and / or its hydrochloride patch. Background technique [0002] Side effects such as nausea and vomiting accompanying cancer radiotherapy and chemotherapy are difficult to control and avoid. Vomiting not only makes patients feel unpleasant, but also may cause severe dehydration and malnutrition, bringing great pain to patients. [0003] Chemotherapy, radiotherapy, surgery and other factors can cause enterochromaffin cells to release 5-HT, and 5-HT can activate 5-HT in the central or vagus nerve 3 receptors that trigger the gag reflex. 5-HT 3 Receptor antagonists can block the gag reflex induced by 5-HT through both peripheral and central mechanisms. Therefore 5-HT 3 Receptor antagonists can be used as antiemetic drugs, such as granis...
