Questions & Step-by-Step Solutions
Which of the following routes of administration typically results in the highest bioavailability?
Step 1: Understand what bioavailability means. Bioavailability is the amount of a drug that enters the bloodstream when it is introduced into the body.
Step 2: Learn about different routes of administration. Common routes include oral (by mouth), intravenous (directly into a vein), intramuscular (into a muscle), and subcutaneous (under the skin).
Step 3: Recognize that intravenous administration means the drug is injected directly into the bloodstream.
Step 4: Realize that when a drug is given intravenously, it bypasses the digestive system and other barriers, leading to 100% bioavailability.
Step 5: Compare this with other routes, like oral administration, where some of the drug is lost in digestion, resulting in lower bioavailability.
Step 6: Conclude that intravenous administration typically results in the highest bioavailability because the drug is delivered directly into the systemic circulation.
