What is one reason why sublingual administration might be preferred?

Sublingual administration is preferred primarily because it avoids first-pass metabolism. When a drug is taken sublingually, it is absorbed directly into the bloodstream through the tissues under the tongue. This allows the medication to bypass the liver and gastrointestinal tract, where it might otherwise be extensively metabolized before it reaches systemic circulation. Consequently, this direct absorption can lead to a faster onset of action and a higher bioavailability compared to other routes of administration, like oral ingestion, where the drug is subject to first-pass metabolism.

The other options do not adequately capture the primary advantage of sublingual administration. For instance, the taste of the medication is not a primary factor in determining the effectiveness or preference of administration routes; effectiveness and bioavailability are much more crucial. Cost of production can vary widely by formulation and is not inherently linked to the sublingual route itself. Storage considerations may also differ but are not a defining reason for choosing sublingual administration over others. Hence, the avoidance of first-pass metabolism stands out as a significant reason for the preference.
