most rapid rate of absorption and drug response A. Intramuscular B. Rectal C. Subcutaneous D. Inhalation E. Oral

Answer: Option A) Intramuscular

Explanation:

A drug is administered directly inside the muscle by means of syringe is most rapidly absorped and stimulating response due to:

- its active form is immediately transported by blood to the target cell where it exerts its function, thus shortening time of travel

- it avoids digestion that could have destroyed some of its potent functional groups

Thus, 'intramuscular' gives the most rapid rate of absorption and drug response
