4 basic concepts of rational use of pigs

Rational use of drugs is based on systematic knowledge and theory of contemporary pharmacology and disease, using drugs safely, effectively, economically and appropriately.

First, the premise of safe use of drugs

Drug safety matters are the primary indicators for assessing the rationality of medication, not only to ensure the safety of pigs applied, but also to cause tissue damage in pigs. The spleen seedlings may be fatal to newborn piglets. The PRRS attenuated vaccine can cause the epidemic. The steroidal anti-inflammatory drugs can damage the liver and kidney. The potassium-containing antibiotics can cause a lethal cardiac arrest with a large number of rapid intravenous injections. Pig calcium chloride can also cause cardiac arrest. When the uterus has residual fetus, uterine rupture with ergot can occur, which is a problem that must be solved by clinical medication.

Second, effectiveness is the primary goal of rational drug use

The effectiveness is different depending on the purpose of the medication. There are control of infection, there are symptoms to relieve, there are ways to avoid adverse reactions, there is synergy, there is prevention of disease. That is, or the same medicine, because the purpose is different, the effectiveness is also different. For example, Annagar, the recovery period of the disease can encourage the stomach and intestines, increase appetite, breast edema can increase the blood circulation and diuresis through the heart, thereby reducing edema. Common cure rates, significant efficiencies, improvement rates, inefficiencies, disease morbidity, and reduced mortality are measured by the effectiveness of the drug.

3. Economics is the social basis for rational use of drugs.

It is a reasonable demand and desire of people to control pig diseases with the least amount of money. If you can use cheap medicine, you don't need expensive medicine. You can use a single prescription without a compound medicine. You can use a small dose without a large dose.

Fourth, appropriateness is the only measure to achieve rational drug use

Appropriateness is to achieve the appropriate medication target by appropriate medication, at the appropriate dose, at the appropriate time, through appropriate routes, to the appropriate individual, using the appropriate course of treatment. When all of the above is done properly, rational use of the drug will be done. The appropriateness of drug use in the prevention and treatment of swine disease is very poor. Many drugs do not specify the content of the active ingredient. It only refers to the number of milliliters per kilogram of body weight. It is common to use large doses. The use of antibacterial drugs does not mention the aftereffect of antibacterial drugs. (PAE for short, that is, the short-term contact between bacteria and antibacterial drugs, the effect of bacterial growth is still inhibited when the drug is eliminated). Many antibacterial drugs can be administered once a day in the case of a one-day dose; newborn piglets are not full of muscles and poorly absorbed by intramuscular injection, especially in diarrhea, and oral administration is a better route of administration.
