Which method of administration delivers drugs directly to lungs?

The method of administration that delivers drugs directly to the lungs is inhalation. This can be achieved through various devices such as metered-dose inhalers (MDIs), dry powder inhalers (DPIs), or nebulizers. Inhalation allows for rapid absorption of the medication into the bloodstream and provides localized treatment for respiratory conditions. This route is commonly used for medications like bronchodilators and corticosteroids in the management of Asthma and chronic obstructive pulmonary disease (COPD).
