What is a transdermal system designed to do?

A transdermal system is specifically designed to release medication into the body through the skin. This method allows for the delivery of drugs in a controlled manner over an extended period, which helps maintain a consistent level of medication in the bloodstream. Transdermal systems, such as patches, provide an alternative to oral or injectable routes, making it easier for patients to adhere to their treatment regimens.

The technology behind transdermal systems ensures that the medication penetrates the skin barrier and enters the systemic circulation. This bypasses the gastrointestinal tract and first-pass metabolism in the liver, potentially leading to improved efficacy and reduced side effects.

Other options relate to different forms of medication delivery. Immediate relief of symptoms refers to fast-acting medications, whereas intravenous administration involves directly injecting medication into the bloodstream, distinct from the gradual release of transdermal systems. Storing medication for future use does not align with the purpose of transdermal systems, which are actively delivering medication rather than holding it for later.
