Inhalation drug administration has a rapid onset of action because drugs are absorbed quickly through the large surface area of the lungs. This route of administration delivers drugs directly to the site of action in the lungs, allowing for high local drug concentrations and reducing systemic side effects.

Metered-dose inhalers (MDIs), dry powder inhalers (DPIs), and nebulizers are all devices used for inhalation drug administration. MDIs deliver a measured dose of medication in aerosol form, DPIs deliver medication in powder form, and nebulizers convert liquid medication into a fine mist for inhalation.

Inhalation drug administration requires coordination and proper technique to use inhalation devices correctly. Patients must be able to inhale deeply and hold their breath to ensure that medication reaches the lungs.

a. Inhalation drug administration has a rapid, not slow, onset of action.

c. The cost of inhalation drug administration can vary depending on the medication and device used, but it is not necessarily more expensive than other routes of administration.

d. Inhalation drug administration is non-invasive.

Albuterol is commonly administered by inhalation for the treatment of asthma and chronic obstructive pulmonary disease (COPD). This route of administration allows for rapid relief of bronchoconstriction and shortness of breath.

b. Furosemide is commonly administered orally or intravenously, not by inhalation.

c. Metoprolol is commonly administered orally, not by inhalation.

d. Simvastatin is commonly administered orally, not by inhalation.

Inhalation drug administration delivers drugs directly to the site of action in the lungs, allowing for high local drug concentrations and reducing systemic side effects.

a. This statement is false because inhalation drug administration delivers drugs directly to the site of action in the lungs, not in the liver.

b. This statement is false because inhalation drug administration has a faster onset of action compared to oral administration.

d. This statement is false because inhalation drug administration is non-invasive.
