Do you know, do you know, a few things about effervescent tablets

On the green grassland with sweet green grass and peaceful and tranquil environment, there lived a group of carefree little white sheep. There were the clever and clever Pleasant Sheep, the gentle and beautiful Beautiful Sheep, the warm and considerate Warm Sheep, the gentle Sheep Doctor, and the amiable village chief Slow Sheep. In the Sheep Village, new things happened every day, and the lambs also needed to go to class and learn some knowledge every day. Suddenly, one day, something special happened. After that, the lambs had a clearer understanding of some things. As usual, the lambs came to the classroom early, prepared the learning materials for the day, and waited for class. However, today, something was suddenly different from usual. The usually lively Pleasant Sheep was now sick and had no energy. One of the lambs couldn't help asking: "Pleasant Sheep, what's wrong with you? Why do you look so listless today?" Pleasant Sheep replied: "I didn't close the window well last night, caught a cold at night, and then I caught a cold and had a fever today, and I'm not feeling well." When the other lambs heard what Pleasant Sheep said, they also showed a very worried expression. When Nuanyangyang heard what Xiyangyang said, she suddenly remembered that she usually carried medicine with her. She quickly searched and finally found a medicine for treating colds and fevers. It was an effervescent tablet. Nuanyangyang was very happy that she brought medicine today and could help Xiyangyang. So, she handed the medicine to Xiyangyang and said, "Xiyangyang, I have medicine for treating colds here. You can take some and relieve it." At the same time, she also handed Xiyangyang a glass of water. Xiyangyang thanked Nuanyangyang, took the water and medicine and swallowed them. However, just 10 seconds after taking the medicine, Xiyangyang's hands and feet suddenly trembled, and then he began to cough violently, and the color of his lips began to turn purple.

The lambs were frightened by this situation and rushed to find a doctor. Fortunately, this class was taught by Dr. Sheep, who arrived in the classroom when Pleasant Goat showed symptoms after taking the medicine. He quickly checked Pleasant Goat's condition, suddenly realized what was wrong, and quickly implemented rescue measures. Pleasant Goat was very lucky to receive timely treatment and survive the critical period.

The lambs were relieved. But Nuanyangyang felt very guilty towards Xiyangyang. Xiyangyang said that she was kind-hearted and did not blame her. After understanding the whole story, Dr. Sheep comforted Nuanyangyang. He said to the lambs: "Everyone knows what happened today. It was caused by irrational medication. So I will take this opportunity to introduce to you how to use effervescent tablets and the common sense of children's medication. After you master it, this situation will not happen again."

The class was filled with knowledge and the students' expectations. 'Effervescent tablets are a special type of drug that is different from ordinary tablets. They contain organic acids and sodium bicarbonate. Effervescent tablets are dry and do not contain water. Organic acids and sodium bicarbonate cannot ionize and cannot react chemically in an environment without water. When they come into contact with water, they react quickly and release a large amount of carbon dioxide gas. They will boil in water, so they are called effervescent tablets.'

"Now that you know the composition and effervescent principle of effervescent tablets, can you speculate the reason why Pleasant Goat has suffocation-like symptoms?" Dr. Goat asked. "Because effervescent tablets will produce a large amount of carbon dioxide when they come into contact with water, when we take effervescent tablets directly, the water we drink will cause the organic acid in the effervescent tablets to react with sodium bicarbonate to quickly produce a large amount of carbon dioxide. The gas in the mouth will go up along the esophagus, and then quickly fill the entire airway through the throat, causing suffocation," Pleasant Goat answered with understanding.

"What Pleasant Goat said is not wrong. Because many effervescent tablets are made into fruit flavors, children like to take them, which solves the difficulty of children taking medicine and has little irritation to the gastrointestinal tract. Many doctors are willing to prescribe this kind of medicine. However, only by taking this medicine correctly can we treat the disease and ensure safety. Therefore, we should take medicine correctly, for ourselves and for the families who love us." "Next, students can think about how to know whether the medicine in your hand is an effervescent tablet? Does it have any iconic symbols that make it easy for us to identify it?" Doctor Sheep continued to ask questions. "I think the name of the medicine will directly say that it is an effervescent tablet," a little sheep answered with a little thought. After listening, Doctor Sheep replied: "The answer is more correct. We can directly look at the name of the medicine. Those with the word "effervescent" in the name are all effervescent tablets."

Then the students further understood that the correct way to take effervescent tablets is to put the tablets in a cup and add half a cup of cold boiled water. After the tablets are completely dissolved and the bubbles disappear, stir and shake well and drink it. Remember that it cannot be taken orally.

Yangcun Medication Tips reminds children and parents:

(1) Effervescent tablets should be sealed and stored safely. They are generally not kept in the refrigerator because the refrigerator is relatively humid and the tablets can easily absorb water and react, thus losing their efficacy.

(2) Effervescent drugs should be kept out of the reach of children, and children need to take them under parental supervision to prevent danger.

(3) Do not use tea or drinks to dissolve effervescent tablets, especially carbonated drinks, to avoid chemical reactions with the drug and affect its efficacy.

(4) Medicines are not candy and should not be taken casually. Children should use children's medicines and should not be given according to adult standards.
