The treatment of many diseases requires a comprehensive drug treatment process to be given first, on the basis of which, if still not cured, some surgical treatment may be chosen. However, if the drug treatment is not standardized, not only is it difficult to obtain good results, but also, it will lead to the misjudgment of the indications for surgery. As the saying goes, the use of drugs is like the use of soldiers, soldiers, there are “Sun Tzu’s Art of War”, “36 plans” and many other ways to use the military. There is a difference between strategy and tactics. Likewise, drug therapy also requires the “ruler, minister and auxiliary”, also requires the formation of troops, the difference between treatment principles and treatment plans, and so on. Among them, the most basic is the four principles of drug therapy: “adequate amount, adequate course, effective, combined” 1, adequate amount: sufficient drug dosage. In many cases, 3 times a day dosing, many people will forget that intravenous antibiotics, most drugs need 2-4 times / day, that is, at least 2 times / day, and almost all people, daily intravenous antibiotics, are habitual 1 time / day. This often falls short of what is needed for treatment. 2, the full course: adequate course of treatment. But in the case of acute inflammation, from onset to healing, the entire inflammatory process, in most cases, takes at least 2 weeks, which means that drug therapy often requires a 2-week course. In the case of an acute attack of chronic inflammation, this treatment process may be extended. The actual treatment process, people often just take a few days of medication, to be slightly better symptoms, will immediately stop medication, so that the inflammation is often incomplete. 3, effective: effective drug treatment. Different types of inflammation require the selection of different types of medication. Only if you choose the right medication to get good results, it can be called effective. And in many cases, based on just one visit, even the doctor will have problems in choosing medication and will need to follow up promptly after taking the medication in order to constantly adjust and determine the correct type of medication, dosage, time, etc. Moreover, patients themselves will also choose their own medication without the guidance of their doctors. Therefore, the effectiveness of drug therapy, will be affected. 4, joint: joint medication. The occurrence and development of inflammation is a complex process, it is impossible to use a drug from beginning to end, can control the smooth transition of inflammation, therefore, in different stages of inflammation, in the face of different forms of inflammation, for the elimination of the cause, improve the symptoms, in most cases, need a variety of drugs synergistic effect, therefore, the combination of drugs is very necessary.
