Stopping the drug or causing asthma to become a "stealth bomb"

[China Pharmaceutical Network Health and Wellness] Stepping into the summer, the weather is hot, many asthma patients will stop using the medicine if they feel that the condition is getting better. Experts say that asthma is a recurrent disease, and this kind of unauthorized withdrawal may lead to asthma becoming a "invisible bomb."


Stopping the drug or causing asthma to become a "stealth bomb"

Zhao Ziwen, the chief physician of the Department of Respiratory Medicine of the First People's Hospital of Guangzhou, reminded patients to relax their vigilance during the summer. They must adhere to standardized medications, maintain air circulation at home, and go out to avoid contact with allergens such as pollen.

Case: Unauthorized withdrawal, acute asthma attack

Ms. Li, who is in her 40s, has a history of asthma for more than a year. At the beginning, she carefully treated the medication according to the doctor's advice, and regularly checked; later, the condition was well controlled, and she gradually relaxed her vigilance and stopped the medicine herself. A few days ago, I had a cold. She had symptoms of coughing and poor breathing. Her medication did not improve for a few days. Really could not support, the family accompanied to go to the hospital, Ms. Li was more and more difficult to breathe on the road, barely supported the hospital, almost breathless, the face became purple, and the gasping was terrifying. After being rescued by doctors and nurses, it took almost half an hour for her breathing to slowly normalize.

Dr. Zhao Ziwen, chief physician of the Department of Respiratory Medicine, Guangzhou First People's Hospital, explained that the essence of bronchial asthma is a chronic non-specific inflammation of the airway, which can cause cough, shortness of breath, wheezing, chest tightness and other symptoms. Even in the remission phase of asthma, asthma symptoms are controlled, and this inflammation can still exist, and there is still the possibility of recurrent wheezing. Wheezing symptoms are often induced or aggravated by some allergens, such as animal skin, dust mites, pollen, micro-bacteria, and other factors such as exercise, viral infections, weather changes, etc. can also induce asthma symptoms. Patients with major asthma attacks may have difficulty breathing and sudden death, and in severe cases, they may be life-threatening.

Standard medication: go out with bronchodilator

Director Zhao Ziwen introduced that in the clinical practice, some asthma patients were treated with drugs at the time of onset and asthma. When the condition was relieved, they immediately stopped taking the medicine. This practice is very dangerous. This intermittent medication does not maintain the concentration of the drug, and the risk of a patient's wheezing is greatly increased.

The treatment of asthma is not difficult, and the control is not good, mainly because the patient has poor compliance and there is no standardized medication. Some patients use less medicine to save money, but this kind of non-standard medication leads to an acute episode, and the cost of living in a hospital is far higher than the cost of regular medication. At present, inhaled corticosteroids are currently the most effective treatment for this chronic inflammation, and 90% of patients can be well controlled by standard treatment.

Pulmonary function and exhaled nitric oxide (FeNO) monitoring are the most effective indicators for assessing future risk factors for asthma after clear diagnosis of asthma. They should be used for the diagnosis of asthma, starting treatment for 3-6 months, and regular follow-up during later treatment. Even if the lung function returns to normal, if the FeNO value is high, it still indicates that asthma inflammation persists, and there is a possibility of acute exacerbation at any time, so it is still necessary to adhere to inhaled corticosteroids.

Director Zhao reminded that it is best to carry emergency bronchodilators (such as Wantollin aerosol) when going out. In case of asthma attack, you should immediately inhale and relieve symptoms and go to the hospital for further treatment. In addition, in the drug When inhaling, remember to rinse your mouth after inhalation, remove the residual hormones in the mouth and prevent fungal infections.

Daily life: pay more attention to stay away from allergens

Most asthmatics are allergic and may be associated with allergic rhinitis, specific dermatitis, and allergies to aphids, pollen or mold. Director Zhao suggested that in addition to standardizing medication, patients should pay more attention to their lives. Try not to keep pets at home, quit smoking and avoid passive smoking. Do not place perfume or incense sticks indoors. Do not lay carpets in the home, especially in the summer in Guangzhou, the humidity is hot and humid, the bacteria are easy to breed, and the sheets and pillows should be washed frequently and exposed to the sun.

Director Zhao suggested that if the cough is more than one month, the effect of drug treatment is not obvious, or the history of allergic rhinitis, high-sensitivity, and family history of asthma, it is best to do lung function tests in time for early diagnosis and early treatment. Control the condition.

In addition, patients with asthma should communicate with doctors on a regular basis to facilitate the doctor to understand the changes in the condition, develop long-term management strategies, and adjust the treatment plan according to the condition. It can be done by standardizing treatment, controlling asthma symptoms, effectively preventing asthma attacks, and avoiding the development of irreversible lung function damage. Asthmatic patients with better control can even achieve long-term non-occurring effects.
