81. A pharmacy technician should identify that medication absorbed through the skin via a patch is using which of the following administration routes?

Answer: A

Explanation:

Medication absorbed through the skin via a patch uses the transdermal administration route.

Medications that are absorbed through the skin via a patch are classified as transdermal administration. This method allows for the delivery of medication directly into the bloodstream through the skin.

A) Transdermal

This option is correct as transdermal administration specifically refers to the process of delivering medication through the skin, utilizing patches that allow for systemic absorption. This route is advantageous for providing a controlled release of medication and maintaining steady blood levels.

B) Topical

Topical administration involves applying medication to a specific area of the skin for localized effect rather than systemic absorption. While patches are applied to the skin, they are designed for systemic delivery, distinguishing them from typical topical applications.

C) Sublingual

Sublingual administration refers to placing medication under the tongue for rapid absorption into the bloodstream. This route is not applicable to patches, as they do not involve placement in the mouth but rather on the skin.

D) Buccal

Buccal administration involves placing medication between the gums and the inner lining of the cheek, allowing for absorption through the oral mucosa. Similar to sublingual administration, this method does not pertain to the use of skin patches for medication delivery.

Conclusion

The transdermal route is definitively the correct answer, as it specifically describes the absorption of medication through the skin via patches. Other options such as topical, sublingual, and buccal do not align with the characteristics of patch-based medication delivery, which is designed for systemic effects rather than localized or oral absorption.
