Administering a medicinal agent directly into a vein is known as intravenous administration. This method allows for the rapid delivery of medication directly into the bloodstream, facilitating quick absorption and immediate action, which is particularly important in critical care situations or when the medication needs to take effect without delay. Intravenous administration is commonly used for fluids, medications, and nutrients, making it an essential technique in veterinary medicine as well as in human healthcare.

In contrast, other methods such as intramuscular, subcutaneous, and interdermal involve injections into different tissues of the body, each with varying absorption rates and purposes. Intramuscular injections are given in muscle tissue, subcutaneous injections go into the layer of fat beneath the skin, and interdermal injections are applied just under the skin's surface. These methods may take longer for the medicinal agents to enter the bloodstream compared to intravenous administration.
