Why is the subcutaneous route often used?

The subcutaneous route is often favored for medication administration because it allows for controlled release of medication. This method involves injecting medication into the fatty layer beneath the skin, which facilitates a slower absorption rate into the bloodstream compared to other routes, such as intramuscular or intravenous. This gradual absorption can be particularly beneficial for medications that need to maintain stable blood levels over time, such as certain hormones or vaccines.

Controlled release can enhance therapeutic effects and reduce the frequency of dosing, making it convenient for both patients and healthcare providers. Additionally, the subcutaneous route is versatile and can accommodate a variety of medications, including those that may not be suitable for intravenous delivery.

While immediate effects can be advantageous for certain medications delivered through other routes, the subcutaneous route does not typically offer such brisk action. It is not classified as non-invasive when considering alternative administration routes, and while it can deliver liquid medications, it is not limited to only that form. Therefore, the ability to facilitate controlled release stands out as a primary reason for using the subcutaneous route.
