The medicine goes in the lungs in the form of mist.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>This technique is commonly used to treat various respiratory illnesses such as COPD, asthma, and cystic fibrosis.

The use of aerosol therapy to administer drugs is an attractive method with minimal side effects. A compressor or nebulizer converts the medicine into tiny inhalable particles, which are then delivered directly as the patient breathes.<br>The most commonly used medications for aerosol therapy are bronchodilators, antibiotics, antiviral drugs, or corticosteroids.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p><strong>Advantages of Aerosol Therapy</strong></p> <!-- /wp:paragraph --> <!-- wp:list --> <ul><!-- wp:list-item --> <li>If we compare the aerosol doses with systemic ones, they are much smaller.</li> <!-- /wp:list-item --> <!-- wp:list-item --> <li>The onset of action of drugs is much faster.</li> <!-- /wp:list-item --> <!-- wp:list-item --> <li>Compared with parental or oral therapy, aerosol therapy has much fewer systemic side effects.</li> <!-- /wp:list-item --> <!-- wp:list-item --> <li>The target delivery of the administered drug is the respiratory system, largely bypassing systemic first-pass metabolism.</li> <!-- /wp:list-item --> <!-- wp:list-item --> <li>Aerosol therapy is relatively convenient and painless.</li> <!-- /wp:list-item --></ul> <!-- /wp:list --> <!-- wp:paragraph --> <p><strong>Key Factors Influencing the Effectiveness</strong></p> <!-- /wp:paragraph --> <!-- wp:list {"ordered":true} --> <ol><!-- wp:list-item --> <li>Drug-related factors: including aerosol particle diameter, aerosol density, drug viscosity and surface tension, and formulation state.

However, depending on the functionality of the equipment, there are three main types of nebulizers:</p> <!-- /wp:paragraph --> <!-- wp:list --> <ul><!-- wp:list-item --> <li><strong>Jet</strong>: This nebulizer uses compressed gas to form tiny particles of administered medication in the air (aerosol).</li> <!-- /wp:list-item --> <!-- wp:list-item --> <li><strong>Ultrasonic</strong>: This type uses high-frequency vibrations to make aerosol. The particles formed by the ultrasonic nebulizer are larger compared to those formed by the jet nebulizer.</li> <!-- /wp:list-item --> <!-- wp:list-item --> <li><strong>Mesh</strong>: The administered liquid drug passes through the mesh. The mesh is very fine and produces the smallest particles. This type of nebulizer is the most expensive of all.</li> <!-- /wp:list-item --></ul> <!-- /wp:list --> <!-- wp:paragraph --> <p><strong>Selection Criteria:</strong></p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>It's important to consider the following selection criteria for selecting the right nebulizer for aerosol therapy.</p> <!-- /wp:paragraph --> <!-- wp:list --> <ul><!-- wp:list-item --> <li>Look for drug formulation compatibility.</li> <!-- /wp:list-item --> <!-- wp:list-item --> <li>Consider the patient's age and ability to coordinate breathing, and then choose accordingly.</li> <!-- /wp:list-item --> <!-- wp:list-item --> <li>Clinical setting (such as hospital, clinic, or home).</li> <!-- /wp:list-item --> <!-- wp:list-item --> <li>Equipment portability and maintenance requirements.</li> <!-- /wp:list-item --></ul> <!-- /wp:list --> <!-- wp:heading {"level":5} --> <h5 class="wp-block-heading"><strong>(2) Drug Delivery Interfaces</strong></h5> <!-- /wp:heading --> <!-- wp:paragraph --> <p>Different types of aerosol drug delivery interfaces are available in the market. Among them, these are the most commonly used:</p> <!-- /wp:paragraph --> <!-- wp:list --> <ul><!-- wp:list-item --> <li><strong>Mouthpiece</strong>: A rigid or flexible tube fitted to the outlet of a nebulizer, held between the lips to form a seal. Aerosolized medication passes directly through the oropharynx into the lower airways. In vitro and clinical <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4978620/" target="_blank" rel="noreferrer noopener nofollow">studies</a> demonstrate approximately two-fold greater lung deposition versus facemask, making it ideal for adults and cooperative children over age 3.</li> <!-- /wp:list-item --> <!-- wp:list-item --> <li><strong><a href="https://www.wellead.com/products/aerosol-mask/" target="_blank" rel="noreferrer noopener">Aerosol Mask</a></strong>: A soft, anatomically contoured mask that covers the nose and mouth and attaches to the nebulizer outlet. It allows passive inhalation of aerosolized particles, suitable for uncooperative patients, young children under 3, or anyone unable to seal a mouthpiece. Proper fit and minimal dead space are key to optimizing drug delivery.</li> <!-- /wp:list-item --></ul> <!-- /wp:list --> <!-- wp:spacer {"height":"40px"} --> <div style="height:40px" aria-hidden="true" class="wp-block-spacer"></div> <!-- /wp:spacer --> <!-- wp:heading {"level":3} --> <h3 class="wp-block-heading">Procedures for Aerosol Therapy</h3> <!-- /wp:heading --> <!-- wp:paragraph --> <p>Proper use of aerosol therapy is important for achieving great results.
