Usually, the temperature of the water for taking aspirin tablets should be around 40℃ to brew, and the amount of water used for brewing should not be too much, which is around 100ml. Wait until the aspirin tablets are completely dissolved, or after the bubbles in the water completely disappear and then carry out some shaking, shaking about 3s before taking. Usually, if the water temperature of the effervescent tablets exceeds 80℃ or even more, aspirin will experience certain secondary drug failure. Therefore, the infusion of effervescent tablets, especially aspirin, a drug that promotes vascular activation can not be immersed in hot water and boiling water, but also can not be used in cold water or refrigerator water for brewing. Because if you use cold water in the refrigerator to infuse aspirin, the drug will not dissolve, so the optimal infusing temperature is 40 ℃.
