Would a patient receive medicine intravenously by taking a pill?

Answer 1

Well the terms you use are not of the same subgroup. What I mean is that there are several methods of injection or infusion, including:

* Intradermal - between layers of the skin * Subcutaneous - just under the skin * Intramuscular - into the muscle * Intravenous - into the vein/artery * Intraosseous - into the marrow of the bone * Intraperitoneal - into a body cavity Therefore, an injectable medication can be given intravenously depending on which route it normally takes. Sometimes drugs can be administered though few of the different routes however more often it cannot be for various reasons. For example, intraosseous injection introduces pharmological compounds into the blood-brain barrier directly, often used when the drug cannot cross the barrier or breaks down far to quick in the normal systemic circulation. Therefore an intraosseous drug administered intravenously may not reach its target site and be rendered useless.

Of those that can be administered in more than one way, subcutaneous and intramuscular injections can often be interchanged, as well as sometimes intramuscular and intravenous, although one must always be careful of the nuances of the specific substance to be administered.

Answer 2

Intravenously means in the vein, so it would be delivered with an I.V. Taking a pill is done orally, through the mouth. They are two different methods of delivering medications.
