Hello everyone, I am an internist who has been practicing for many years. Cough, I believe everyone has experienced it, so why do people cough? In fact, the ever-changing is inseparable, that is, various reasons stimulate our respiratory tract, so there is a reflex cough, which is a basic defense mechanism of our body, when people have cough what are the common reasons? How do you deal with it in life? Let me now turn to my views.
<h1 class="pgc-h-arrow-right" What factors can cause cough > data-track="2"? </h1>
● Let me first divide the time for you, in general, we can divide into three categories, that is, acute cough, this time is generally less than 3 weeks; sub-acute cough time is generally about 3-8 weeks; chronic cough is greater than or equal to 8 weeks. Like acute cough should be the most common, such as the common cold, the most common symptom caused by cough, other acute bronchitis, acute sinusitis, allergic rhinitis, bronchial asthma, etc., this general primary disease can also disappear with cough. The most common cough like subacute cough is post-infection cough, such as bacterial sinusitis.
●The cause of chronic cough is more common, here can also be a small classification, one is through chest x-ray, CT and other preliminary examination found that there are lung lesions caused, such as pneumonia. Tuberculosis, lung cancer, bronchiectasis, etc.; the other is that most common tests are no problem, but it is a repeated cough, such patients are tossing and turning, repeatedly seeking medical treatment, common causes such as cough variant asthma, eosinophilic bronchitis, gastric-esophageal reflux cough and so on. Therefore, such unexplained chronic cough should still be treated as early as possible in the respiratory medicine specialist clinic, and the solution is to find the cause.
<h1 class="pgc-h-arrow-right" data-track="2" > common interpretation of antitussive drugs</h1>
●Common antitussive expectorant drugs (1): Relapsed licorice tablets, which are a compound preparation, are often bought by ordinary people and put at home for backup. Our adult usage is generally 3-4 tablets each time, 3 times a day can be taken. Oral and containing drugs can be taken orally, but the effect of taking the drug will be faster and there will be fewer adverse reactions. On the one hand, the mechanism of action of this drug is that the main ingredient "opioid powder" has a strong antitussive effect, camphor and star anise oil can stimulate the mucous membranes of our bronchi, thereby reflexively increasing glandular secretion, diluting sputum, making sputum easier to excrete from the body.
●Common antitussive drugs (2): ventolverin tablets, this drug is especially suitable for a variety of causes (such as acute and chronic bronchitis) caused by sputumless dry cough, like our hospital tablets the specifications are generally 24mg a tablet, so three times a day, 1 tablet at a time can be. note! If you cough up more phlegm, then it is best not to use this, just imagine, you have phlegm on this side, and there is medicine to prevent coughing, is not it leading to sputum accumulation in the lungs! This drug is absorbed relatively quickly after oral administration, generally 20-30 minutes can take effect, eat once can maintain 4-6 times, so three times a day to take just right.
● Common antitussive drugs (3): codeine tablets, the antitussive effect of this drug is one grade higher than the above two drugs, clinically we generally use for severe, frequent dry cough. Of course, this drug is not to say that you want to prescribe it, because it is a specially managed narcotic drug of the state, you must have relevant qualified doctors to prescribe, the reason why it has such a strong cough effect, mainly after taking it, can selectively inhibit the "cough center" of the medulla oblongata in our brain, which directly controls the cough command, so the cough effect is strong and rapid, because it has an addiction, so it is generally temporary.
●Common antitussive drugs (4): Dextromethorphan tablets, this antitussive drug is also used for dry coughs caused by bronchitis such as upper respiratory tract infections (such as colds, pharyngitis, etc.). Its drug mechanism of action is similar to the codeine I mentioned above, and it also exerts a central antitussive effect by inhibiting the medulla oblongata cough center of our brain. Its antitussive intensity is equal to or slightly stronger than codeine. But the difference is that it has no analgesic effect, but it should be noted that some people may have dizziness, headaches, want to sleep, etc. after taking the drug, so after taking the drug, it is not possible to drive a motor vehicle, a boat, engage in aerial work, mechanical work, operation of precision instruments, etc. Although the medication course is not addictive, it is only recommended for temporary use.
● Common antitussive drugs (5): recurrent methoxamine capsules, don't look at this medicine on a small capsule, in fact, it is also a compound preparation, if it is over 15 years old, 3 times a day, 2 capsules each time, if it is 8-15 years old, it can be changed to 1 capsule each time. It is composed of methoxyamine hydrochloride 12.5 mg, nacodine 7 mg, aminophylline 25 mg, chlorpheniramine maleate 2mg, the antitussive effect is very good, let's interpret the dust one by one. For example, methoxymetholone hydrochloride mainly inhibits bronchospasm, which relieves cough during an asthma attack, while nacotin is a peripheral cough suppressant that suppresses cough.
●Aminophylline inhibits bronchospasm, inhibits swelling of the bronchious mucosa, relieves cough during asthma attacks, and makes sputum easy to cough up. Chlorpheniramine maleate I think many people should also be familiar with, it is an antihistamine drug. Therefore, the combination can be used to alleviate cough caused by throat and bronchial inflammation, etc., and can also relieve cough during asthma attacks, which is conducive to sputum elimination. However, it should be reminded that this drug should not be used in combination with roxithromycin, because roxithromycin is a liver drug enzyme inhibitor, which can reduce the clearance of aminophylline (the main component of compound methoxamine), significantly increase the blood concentration of aminophylline, which in turn leads to aminophylline poisoning, taking it can appear muscle fibrillation, tachycardia, arrhythmia, serious cases even breathing, cardiac arrest and death, just like taking cephalosporin antibacterial drugs can not drink alcohol, do not underestimate.
<h1 class="pgc-h-arrow-right" data-track="2" > comprehensive summary</h1>
Although the 5 types of common antitussive drugs I listed above have good effects, the most important diagnosis and treatment of cough is the treatment of the cause. For example, if you smoke all year round, cough more than once, then taking medicine is tantamount to scratching the itch in the boot, quitting smoking is the key; if you are taking a certain Puly drug because you have high blood pressure, this is the side effect of this type of drug, so if you can't tolerate changing to other high blood pressure drugs to eat cough naturally improve.
