Review of Modern Devices for Inhalation Therapy

Abstract

Inhalation therapy is the introduction of a medicinal substance directly into the respiratory tract using special inhalers. To date, more than 200 devices for inhalation therapy have been developed. The purpose of the work is to review modern devices for inhalation therapy, to clarify their advantages and disadvantages. Interest in inhalation therapy can be explained by several reasons. Let's list them. First, you can inject the drug directly into the respiratory system. Secondly, the therapeutic effect comes quickly. Thirdly, the drug is almost not absorbed into the blood, so there are no systemic side effects. In addition, the patient can do inhalation independently at home. At the same time, inhalation therapy has several disadvantages. Sometimes it is difficult for the patient to understand how to use the inhaler. The doctor should show, explain and control inhalation. The particle size of the aerosol is very important, as is the patient's inspiratory flow rate.
