The Fastest Route for Drug Response

IV administration is known to provide the fastest drug response of all options given. This is because it bypasses the GI tract and allows the drug to be immediately metabolized by the body.

When the drug is introduced directly into the bloodstream via intravenous administration, the body can begin metabolizing it almost immediately. While oral administration is convenient for the patient, for drugs that do not absorb easily in the GI tract, such as some useful in combating diseases within the intestinal tract, the intravenous or intramuscular administration is preferred.

Overall, the intravenous method provides a faster response time, with higher plasma levels achievable compared to other administration routes.
