Answer 1

Answer:

The answer is option b

Explanation:

The rate of drug absorption is measured by its BIOAVAILABILITY.So the bioavailability for intravenous>intramuscular>subcutaneous>oral administration

Hope this helps

Answer 2

Answer:

Option - i. v > i. m > s. c > oral

Explanation:

1. Intravenous: The medicines are directly introduced into the bloodstream through veins. Hence, the name intravenous. This route is the fastest route for drug administration. The infusions and injections administered this way are 100% bioavailability.
2. Intramuscular: This route involves injecting the medicine directly into the muscle. As muscles are packed with large blood vessels, the absorption rate is faster than the subcutaneous.
3. Subcutaneous: The injection is administered into the fat layer just below the dermis of the skin. The absorption of the drug from this route is slow and sustained action as there are fewer blood vessels in the tissues.
4. Oral: Intake of medicine through the mouth. The absorption rate is very slow and time taking.

Hence, the route of administration in accordance with the rate of absorption is intravenous > intramuscular > subcutaneous > oral.
