CCAP Pharmacology Fundamentals 2

Question 1

Which pharmacokinetic process describes how essential oil constituents are absorbed through the skin into systemic circulation?

Accepted Answer

Transdermal absorption

Answer

Transdermal absorption is the process by which lipophilic essential oil molecules penetrate the skin barrier and enter the bloodstream.

Question 2

The cytochrome P450 enzyme system is most relevant to aromatherapy because it is responsible for:

Accepted Answer

Metabolizing essential oil constituents in the liver

Answer

The hepatic CYP450 system metabolizes essential oil constituents, which can lead to potential drug interactions when enzymes are induced or inhibited.

Question 3

A client taking warfarin asks about using clove essential oil topically. The primary pharmacological concern is that eugenol may:

Accepted Answer

Enhance warfarin's anticoagulant effect by inhibiting platelet aggregation

Answer

Eugenol in clove oil has antiplatelet properties that can potentiate the anticoagulant effects of warfarin, increasing bleeding risk.

Question 4

What does the term 'bioavailability' mean in the context of essential oil administration?

Accepted Answer

The fraction of administered compound that reaches systemic circulation unchanged

Answer

Bioavailability refers to the proportion of an essential oil constituent that successfully reaches systemic circulation in an active form after administration.

Question 5

Which route of administration typically results in the highest bioavailability for essential oil constituents by bypassing first-pass metabolism?

Accepted Answer

Sublingual mucosal absorption

Answer

Sublingual absorption bypasses hepatic first-pass metabolism because venous drainage from under the tongue enters the superior vena cava directly, not the portal circulation.
