With the arrival of the holiday season, the number of people suffering from acute pharyngitis, or recurrence of chronic pharyngitis due to excessive smoking and alcohol, spicy food, is increasing, and the symptoms are worsening. The symptoms often manifest as throat discomfort, dry cough, foreign body sensation, and even sore throat and fever. The first thing people think of when they get sick is to go to the pharmacy and buy some oral tablets to treat it, and some people even want to prevent pharyngitis attacks by taking oral tablets for a long time. A. Can this play a preventive role? Currently on the market can be seen in the oral tablets, according to its role can be divided into five categories: 1, with bactericidal effect class tablets: Clomid tablets, Tylenol oral tablets, Dumefen tablets, etc.. 2, with antibacterial effect of class tablets: silver yellow containing tablets, containing iodine tablets, clear throat drops, gold chrysanthemum li-pharyngeal oral tablets, watermelon cream tablets, grass coral tablets, lysozyme oral tablets, etc.. 3, with the role of virucidal class: ribavirin oral tablets, etc. 4, with the role of camp health class tablets: vitamin C oral tablets. 5, special diseases of special tablets: insulin oral, growth factor oral tablets, fast-acting heart pills, etc.. The first three categories are commonly used to treat acute and chronic pharyngitis. The normal human pharynx is present in a variety of bacteria such as streptococcus, staphylococcus, H. influenzae, but also viruses and fungi. Recently, it has been reported that the normal flora that can be isolated from the human pharynx include a variety of Streptococcus, Pronibacterium, Staphylococcus, dense spirochetes, Mycobacterium-like bacteria, Lactobacillus, Neisseria, Candida, Meningococcus, Haemophilus influenzae, Parainfluenzae, and Actinomyces. The presence of microorganisms in the pharynx has both advantages and disadvantages and has its two sides. The good side is that their presence keeps the body’s immune system “active” and can respond quickly and effectively when other microorganisms invade; the bad side is that when the body’s resistance decreases, they can be transformed into disease-causing pathogens, causing diseases such as acute pharyngitis. In the treatment of acute and chronic pharyngitis, the correct and appropriate use of oral tablets can play a role in reducing the symptoms and shortening the course of the disease. Second, but if used for a long time with high frequency, the consequences are: 1, inducing resistance to bacteria or viruses. 2, kill the normal non-pathogenic bacteria parasitic oropharynx, change the oral and pharyngeal pH. 3, destroy the normal flora of the oropharynx to maintain a balanced symbiotic state between the constraints of each other, can cause the normal flora balance between bacteria disruption, reduce local immunity, induce the occurrence of pharyngitis, and even cause secondary secondary infection.
