Currently, there is a wide variety of drugs on the market for the treatment of colds, but according to the classification of the mechanism of action, it is mainly divided into four categories of anti-allergy drugs, drugs to reduce nasal mucosal congestion, antipyretic and analgesic, antiviral drugs: anti-allergy drugs can alleviate the symptoms of sneezing, nasal congestion, runny nose, and at the same time, have a slight sedative effect, such as chlorpheniramine (Paracetamol) and Benzphenamine, etc.. Decongestive drugs can selectively constrict the blood vessels of the nasal mucosa, reduce the symptoms of nasal congestion and make the nose less runny, such as phenylpropanolamine and pseudoephedrine. Antipyretic and analgesic drugs can reduce fever, relieve headache, joint and generalized muscle pain and other symptoms, such as aspirin, acetaminophen, diclofenac and so on. Antiviral drugs can inhibit viral synthesis of nucleic acids and proteins, and inhibit the release of viruses from cells, reducing the severity of viral infections. Commonly used antiviral drugs include viral azole, acyclovir, and amantadine. There are also many Chinese medicines for treating colds, such as the proprietary Chinese medicine Yin Qiao Xie Tu Pill, Sang Ju Cold and Flu Tablet, Antelope Cold and Flu Tablet, Cold and Flu Clearing and Heat Punch, Huo Xiang Zheng Qi Punch, etc. Chinese medicines, such as Chai Hu, Pueraria Mirifica, Rhizoma Coptidis, Honeysuckle and so on, have antiviral effects that are not found in Western medicines. For example, Chaihu has obvious antipyretic effect on fever caused by various reasons, and is characterized by low toxicity and rapid fever reduction. In terms of antiviral, in addition to inhibiting influenza bacillus, S. pneumoniae and P. aureus, it also has a strong inhibitory effect on E. coli, P. aeruginosa and dysentery bacillus, so not only can it be used in the treatment of influenza, but also in the treatment of various infections caused by colds and influenza, such as mumps, pneumonia, acute bronchitis, and many other infectious diseases. Common cold and influenza are both caused by viruses, and the effect of current antiviral drugs is not real, so only symptomatic treatment, under the guidance of the doctor to use the appropriate anti-influenza drugs. The common cold is a self-limiting disease and can be cured in 5-7 days under normal circumstances. If the local symptoms are serious, you can take local physical therapy, drink more water, eat some throat protection tablets for sore throat, and use a little nasal congestion to shrink the nasal mucosa. Influenza should be bed rest, drink more water, can be used to treat influenza medicine, such as oseltamivir is for influenza A, B virus medicine, in the early 48 hours of fever, the use of good results. According to Chinese medicine, colds are categorized into wind-cold, wind-heat and summer-heat types, and there is a difference in the medication used. Wind-cold type cold manifests itself in the form of headache, no sweat, pain in the limbs, nasal congestion, heavy voice, runny nose, cough, sputum, white sparse, thirst, white tongue, the treatment should be the choice of pungent and warm antidote to the table class of drugs, to promote the lungs to disperse cold. Chinese patent medicine can choose cold punch, Tongxuan Lung, small Chaihu tablets, etc., the rural areas with fresh ginger chopped and white onion a piece of boiled water, drink while hot, slightly sweating out the disease can be self-healing. Wind-heat type cold is characterized by heavy fever, mild chills, headache, nasal discharge of mucus or yellow snot, sore throat, cough, yellow and thick sputum, thirst, yellow or white tongue coating, it is advisable to clear the lungs and remove heat, pungent and cool to relieve the epidermis, and it can be used in Yin Qiao Xie Tu Pill, Sang Ju Cold and Flu Tablet, Antelope Cold and Flu Tablet or Cold and Flu Cleansing Hot Liquid orally. For summer-heat type colds, it is advisable to clear heat and dispel heat, and clear Qi to separate heat, and use Huo Xiang Zheng Qi Punch or oral liquid. Some traditional Chinese medicine practitioners also distinguish between the three types of colds mentioned above and the cold-heat type. The person often eats high-calorie food, has unbalanced nutrition, has a hot constitution, has internal fire, and has an external wind-cold, which causes internal heat stagnation. In some cases, wind-cold infection is not treated properly and the illness is not cured for a long time, causing internal heat stagnation. The first step in the treatment of cold and internal heat type of cold is to use pungent and warm to remove the external cold, and then evacuate the heat. It is worth noting that there are a lot of adult cold medicines that are harmful to children. Therefore, pediatric cold and flu medication should be particularly cautious, such as fast-acting cold capsules, cold and flu, and painkillers and other drugs, containing paracetamol, finasteride, aminopyrine, caffeine and other ingredients. These ingredients can have an inhibitory effect on the bone marrow hematopoietic system, affecting the generation and growth of pediatric blood cells, leading to leukopenia and granulocyte deficiency, reducing the immunity of children, and some can cause toxic liver damage. Compound aspirin has an excitatory effect, infants and young children's neurological inhibitory mechanism is not yet sound, infants and young children with high fever when using compound aspirin, easy to induce convulsions, but also due to a large number of sweating caused by dehydration, and even jaundice due to the accumulation of free bilirubin in the blood. At the same time, this drug on the digestive system and liver and kidney function has damage, some may cause Reye's syndrome, resulting in white blood cells, platelets lower, especially for young children under the age of 3 years old, generally do not advocate the use of this drug. Experts believe that the cold should not be taken lightly, especially the elderly and infants, but do not panic, do not abuse the cold medicine, do not follow the advertisement to use medicine, do not move on the infusion, especially do not easily use antibiotics. Colds are usually viral infections, and antibiotics have no effect on viruses, but rather increase the body's resistance to antibiotics. Unless the occurrence of combined bacterial infection, pneumonia, generally do not need to use antibiotics.
