1. Why is inhaled medication the best method of administration for asthma treatment? Inhaled drug delivery method for asthma is a milestone leap in the long process of human’s long struggle with asthma treatment. Inhalation therapy is currently recommended by medical experts at home and abroad for the treatment of asthma, and it has become the preferred treatment method for asthma. This is because the lesion of asthma is the bronchus, inhalation therapy can prevent and control asthma drugs through the breath directly to the lesion, can quickly play a role. When inhaled medication is administered, the amount of medication that is absorbed into the bloodstream and reaches the whole body is minimal. In addition, the dose of medication required for inhalation is much smaller than the dose required for systemic medication such as oral and injectable medication, with the daily dose unit for inhaled medication being micrograms and the daily dose unit for oral and injectable systemic medication being milligrams. One day’s oral and injectable doses are equivalent to six months or a year’s worth of inhaled medications. Inhaled drug delivery is faster and more effective than systemic drugs, while toxic side effects are significantly reduced and mitigated. Therefore, inhalation is currently the preferred method of drug delivery for asthma control. Li Li, Department of Pediatrics, Children’s Hospital of Soochow University, Suzhou, China 2. Is it necessary to treat pediatric asthma in remission? This is a question that parents are not very clear about. Some parents do not insist on treating their children during the remission period because they are not clear about this issue, or they do not want to accept the fact that their children have asthma, or they are worried about the side effects of the medication, or their children do not comply well, and so on, resulting in recurrent asthma attacks. Treatment is needed during the remission period, when the child is not having an asthma attack, and treatment during the remission period is very important. It has been found that during the remission period of asthma, although the asthma symptoms are relieved, the chronic inflammation of the airways still exists and the airway hyperresponsiveness also remains, only to a different extent. In this case, once encountering allergens, triggering factors and respiratory infections, an asthma attack will be triggered. Therefore, the remission period of asthma is the best period for children to recover their strength, strengthen their body and improve the chronic inflammation of the airways, and it is also a critical period for the treatment of asthma. Effective treatment during the remission period can not only control asthma attacks but also reduce the symptoms of asthma attacks, and it is beneficial to enhance the physical fitness of the children and improve their resistance to disease, which is of great significance in the treatment of asthma and is an important part of the standardized treatment of asthma. In other words, that is, the acute phase of an asthma attack is to relieve the symptoms as soon as possible, while the remission phase is to cure its root.
