How to choose expectorants when coughing, what children should pay attention to when taking medication, what medications can be taken to prevent myocardial infarction, and what are the precautions for drinking water and taking medication... The Chinese Pharmaceutical Association recently released the "Top 10 Medication Tips for the Public in 2023", calling on the public to understand safe medication knowledge and avoid medication misunderstandings. Coughing is one of the most common symptoms of the respiratory system. It is a defensive reflex action caused by irritation of the respiratory mucosa. Coughing can clear secretions and foreign objects in the respiratory tract. In pathological conditions such as respiratory inflammation, an increase in respiratory secretions can exacerbate coughing, and a large amount of sputum can also block the respiratory tract, causing breathing difficulties, breeding pathogens, and causing infection. When coughing cannot smoothly expel phlegm, expectorants can be considered for symptomatic treatment. Common expectorants can be divided into the following types: nauseous and irritating expectorants. Representative drugs: ammonium chloride, guaiacol glycerol ether, often used in combination with other cough and phlegm suppressants to form compound preparations, such as compound licorice oral solution, brown ammonium mixture, etc. After taking it, it stimulates the gastric mucosa and causes mild nausea. It reflexively increases the secretion of tracheal and bronchial glands, making sputum thinner and easier to cough up. Excessive dosage of such drugs can cause more adverse reactions, such as vomiting, bloating, palpitations, etc. Especially for patients with liver and kidney dysfunction, caution should be exercised when using them. Stimulating expectorant medication. Representative drugs: eucalyptus oil, guaiacol, benzoin tincture, turpentine, etc. These types of drugs are mainly volatile substances that have a mild irritant effect on the respiratory mucosa. They can cause mild congestion of the mucosa, accelerate local blood circulation, and also moisten the respiratory tract. Through these effects, the viscosity of sputum is reduced, making it easy to cough up. This type of drug also has a certain disinfection and anti-corrosion effect, which can inhibit the growth of respiratory bacteria. Mucus dissolving medicine. Representative drugs: Bromhexine, Acetylcysteine, Ambroxol, Standard Myrtle Oil, Carboxymethylstane, etc. This type of medication can cause the breakdown of mucopolysaccharide fibers in mucus, or inhibit the synthesis of acidic glycoproteins, while also breaking down mucin, thereby reducing the viscosity of sputum and making it easier to cough up. Acidic drugs can significantly reduce the effect of acetylcysteine and should be avoided in combination. Patients should seek medical attention promptly, identify the causes of increased sputum production, and choose appropriate treatment plans under the guidance of doctors and pharmacists. It should be noted that expectorant drugs are only one aspect of the treatment for respiratory diseases such as pneumonia and bronchitis. Often, it is necessary to combine multiple other drugs for comprehensive treatment. Therefore, when using expectorant drugs, attention should also be paid to the issue of combining medication. When using expectorants, attention should be paid to avoiding the use of strong cough suppressants at the same time, because expectorants dissolve and dilute mucus, enhance ciliary movement, and promote the discharge of phlegm. When using strong cough suppressants together, it will make it impossible to cough up phlegm and achieve the purpose of expectorants. Only severe coughers need to use cough suppressants for control.
