Abstract
The invention relates to the technical field of medicines, in particular to a cooling gel sheet and a preparation method thereof. The cooling gel sheet comprises a back lining material, a gel matrix layer and a cover lining material, wherein the gel matrix layer is prepared from menthol, tartaric acid, silanediol salicylate, sodium polyacrylate, glycerin, aluminum glycinate, disodium ethylenediamine tetraacetic acid, a preservative and water. The cooling gel sheet has the advantages that when the cooling gel sheet is stuck, the quick cooling effect is realized by the volatilizing of menthol and gasifying of water; because the silanediol salicylate absorbs a certain amount of menthol, part of menthol slowly volatilizes, the cooling time can be prolonged, and the defects of short action timeand poor suitability in the existing cooling gel sheet are overcome; the preservative contains glycerol octanoate, octyl hydroxamic acid and p-hydroxyacetophenone, so that the moisturizing effect ofglycerol is increased, the function of maintaining the stability of the hydrogel matrix in the gel sheet is realized, the easiness in solidification of the gel matrix due to influence by temperature and overquick evaporation of water is avoided, the stability of the hydrogel matrix in the gel sheet is maintained, and the cooling time is prolonged.
Description
technical field [0001] The invention relates to the technical field of medicine, in particular to an antipyretic patch and a preparation method thereof. Background technique [0002] Fever is one of the most common clinical symptoms, usually caused by viral, bacterial infection or other diseases. Fever is a protective reaction of the human body. Fever can stimulate the phagocytic function of the reticuloendothelial system, form antibodies, increase the vitality of white blood cells, and detoxify the liver. However, fever can cause loss of appetite and fatigue, and affect the function of various organs and tissues in the body Function. In order to quickly cool down, people generally take antipyretic and analgesic drugs, as well as antibacterial and anti-inflammatory antibiotics, and taking drugs will bring adverse reactions to the human body, especially pregnant women, infants and other special groups should not take antibiotics. [0003] Antipyretic patches are also called...
