Answer:
The therapeutic effect of an IM (intramuscular) administration is best explained by the fact that the muscle has a rich blood supply, so the drug is absorbed quickly. Intramuscular administration involves injecting medication directly into a muscle, where it can be quickly absorbed into the bloodstream and distributed throughout the body. The rich blood supply of muscles allows for rapid absorption and onset of therapeutic effects. This route of administration is often used for drugs that need to act quickly, such as emergency medications or vaccines.
In contrast, administration via the skin (topical) may result in slow absorption, as the skin has a poor blood supply. This can be advantageous for some drugs, such as topical creams or patches that provide a slow and controlled release of medication. However, for drugs that need to act quickly or have a systemic effect, IM administration is a more appropriate route.
Administering a treatment orally by dissolving in the mouth (sublingual administration) allows for controlled release of the drug but it is a different route of administration altogether and may not be appropriate for all medications.
