Veterinary drugs include not only commonly used drugs such as antibiotics and biological products (bacteria), but also various drugs such as Chinese herbal medicines, proprietary Chinese medicines, radiopharmaceuticals, biochemical drugs, chemical raw materials, and their preparations. At present, my country's animal husbandry industry is booming, the number of veterinary drugs and the variety is also increasing, but with it, the quality of veterinary drugs is difficult to control, and the unqualified veterinary drug products emerge in an endless stream. Faced with such problems, factors affecting the quality of veterinary drugs should be found and controlled, to ensure the quality and safety of veterinary drugs. So, what are the environmental factors that affect the quality of veterinary drugs? Let's take a look.
Here is the table of contents:
l Sunlight
l Air
l Temperature
l Humidity
After some veterinary drugs are irradiated by sunlight, the ultraviolet rays in the sunlight will catalyze the drugs and speed up the oxidation and decomposition of veterinary drugs, making veterinary powder invalid and deteriorating within the validity period, affecting the use. There are not only visible light but also infrared light and ultraviolet light in sunlight. Optical fibers with different wavelengths can cause photochemical oxidation or hydrolysis of drugs. At the same time, sunlight may also cause or accelerate the oxidation, reduction, and decomposition of drugs.
There are various gases in the air, and these gases are in contact with veterinary drugs for a long time, which can easily cause the acidification of veterinary drugs, thereby causing the failure of veterinary drugs. For example, oxygen in the air can combine with the phenolic hydroxyl group in phenolic substances to undergo oxidation reaction, and undergo oxidation reaction with the enol structure in VC to generate diketone compounds, and then become colored ineffective drugs through further oxidation. Some drugs can form new substances with carbon dioxide in the air, thereby changing the original effect.
Veterinary tablets usually have strict temperature requirements. Too high or too low ambient temperature can easily cause drug failure. When the temperature is high, the oxidation and decomposition reactions of veterinary powder will be accelerated, and the rate of deterioration of the medicine will also be accelerated. Drugs such as bleaching powder for silkworms should be stored at low temperatures. If the temperature is too high, the decomposition reaction of the drug will be accelerated and the benefits of chlorine will be promoted. When the temperature is too low, the medicine is prone to certain precipitation or solidification of the liquid medicine, thus losing its activity.
When the humidity in the air is too high, deliquescence and mildew will occur after the medicine comes into contact with the air. Although deliquescence will not change the properties of the medicine, the dosage of the medicine will change due to the absorption of water in veterinary tablets. Deliquescence can also cause the spoilage of medicines, especially Chinese veterinary medicines. Herbs are easy to absorb water in the air. When the water content is too large, it will cause spoilage. The low humidity in the air will also cause the loss of crystal water in veterinary external medicine, resulting in weathering, and the quality of the weathered medicine will become lighter, which will affect the use of the medicine.
