Answer:
False.
The absorption rate of inhaled corticosteroids (ICS) can vary depending on factors such as the specific medication, the device used for inhalation, and individual patient factors. However, it is generally not accurate to state that approximately 80% of an ICS dose is systemically absorbed.
Inhaled corticosteroids are designed to have a primarily localized effect within the lungs to reduce inflammation and manage conditions like asthma or chronic obstructive pulmonary disease (COPD). While some small portion of the medication may be absorbed systemically (into the bloodstream), the goal is to minimize systemic absorption to reduce the risk of systemic side effects commonly associated with oral corticosteroids.
The extent of systemic absorption can vary, but it is typically much lower than 80%. The actual absorption rate can depend on factors like the specific corticosteroid, the inhalation technique, and the patient's individual characteristics. It is important for healthcare providers to consider these factors when prescribing and monitoring ICS use to ensure the most effective and safe treatment.
