What are the ingredients in cold medicine? Common sense
1. Acetaminophen
Commonly known as: paracetamol. It has antipyretic and analgesic effects. Its mechanism of action is to produce peripheral vasodilation by inhibiting the synthesis and release of hypothalamus thermoregulation central prostaglandin (PGE2), causing sweating to achieve antipyretic effects. At the same time, it can inhibit the effects of bradykinin, etc., and increase the pain threshold to produce analgesic effects.
2. Pseudoephedrine Hydrochloride
Adrenergic drugs have the effect of constricting the capillaries of the upper respiratory tract, eliminating the congestion of the nasopharyngeal mucosa, and reducing the symptoms of nasal congestion. (To put it bluntly, it is to reduce the symptoms of nasal congestion, but note that this is not a treatment for the cold. This way to reduce nasal congestion is to treat the symptoms rather than the root cause, and it also has side effects on the human body. Many cold medicines have this ingredient.) Many medicines that are claimed to specialize in nasal congestion are actually added with this ingredient, such as NeoContek.
3. Amantadine hydrochloride
Anti-influenza virus effect. Cold medicine containing this ingredient is anti-influenza virus cold medicine. Mainly for type A influenza virus. This article requires special attention, because the common cold and the flu are not the same thing. Flu is generally a viral cold, and it is difficult to take ordinary cold medicine to work. You must take the corresponding antiviral cold medicine according to the situation. However, the common antiviral cold medicine on the market is relatively single and sometimes difficult to treat. In this case, it is best to go to the hospital for treatment.
4. Chlorphenamine maleate
This ingredient is anti-allergic, but it can cause drowsiness (that is, drowsiness), which is why many cold medicines are sleepy. But this ingredient cannot be removed in many cold medicines, because the main ingredient of most cold medicines is acetaminophen. This ingredient has allergic reactions to some people, so chlorphenamine maleate must be used to fight allergies. Some medicines that do not show obvious symptoms of drowsiness take anti-allergic ingredients like diphenhydramine hydrochloride instead of chlorphenamine maleate.
Step 5 Caffeine
Central nervous system exciters, central exciters can enhance the efficacy of antipyretic and analgesic drugs, and secondly, can reduce the drowsiness symptoms of cold medicines.
6. Artificial bezoar
It has antipyretic and calming effects
7. Dextromethorphan Hydrobromide
It can inhibit the cough center and has a cough-relieving effect. However, many cold medicines do not have this ingredient. Common cold medicines on the market only contain this ingredient in individual medicines such as white and black. This cough-relieving method is similar to suppressing nasal congestion, and it relies on acting on nerves and blood vessels to achieve its purpose, not the root cause.
8. Ibuprofen (Fenbid)
Its anti-inflammatory, analgesic and antipyretic effects are stronger than aspirin, butazone or acetaminophen. But most domestic cold medicines are still mainly acetaminophen. Fewer use ibuprofen or aspirin.
