Induction dosing is typically administered in what manner?

• A. Intravenous
• B. Intramuscular
• C. Oral
• D. Subcutaneous

Answer: (A)

Induction dosing is about achieving therapeutic drug levels as quickly as possible, so the effect begins promptly and can be tightly controlled. Delivering the dose intravenously flows directly into the bloodstream, giving near-immediate onset and allowing precise titration of the dose. This makes IV administration the best choice for induction, especially in situations like anesthesia where rapid, reliable onset is crucial.

Oral dosing must go through digestion and liver metabolism before reaching the bloodstream, leading to slower, less predictable onset. Intramuscular and subcutaneous routes rely on absorption from the injection site, which varies with blood flow and tissue factors and tends to be slower and less predictable than IV.
