Aerosol delivery systems are devices that disperse medication in the form of tiny droplets or particles, allowing for easy inhalation into the lungs. These systems are commonly used for respiratory conditions, such as asthma and chronic obstructive pulmonary disease (COPD), providing quick relief by delivering medication directly to the airways. There are various types of aerosol delivery systems, including metered-dose inhalers (MDIs), dry powder inhalers (DPIs), and nebulizers. Each system has its own method of operation, but all aim to improve the efficiency of drug delivery, ensuring that patients receive the necessary treatment effectively and conveniently.
