What does the term transdermal refer to?

The term transdermal refers specifically to the process of delivering medication or substances across the skin barrier and into the bloodstream. This method is commonly utilized in medical treatments through patches, creams, or gels that allow for controlled release of medications over time. By bypassing the digestive system and direct entry into the bloodstream, transdermal delivery can enhance the effectiveness of certain drugs and reduce potential side effects associated with other routes of administration.

The significance of this delivery method lies in its convenience and the ability to maintain steady drug levels in the body without the need for multiple doses. It is particularly useful for patients who may have difficulty swallowing pills or require consistent medication levels throughout the day. Understanding this concept is important in health science, as it informs choices about patient care and medication delivery.
