What is the term for the procedure of delivering medication directly into a vein?

The procedure of delivering medication directly into a vein is referred to as IV therapy. This method allows for immediate access to the bloodstream, ensuring that the medication can circulate quickly and effectively throughout the body. IV therapy is particularly advantageous in emergency situations where rapid drug action is crucial, such as administering fluids, electrolytes, or medications like pain relievers or antibiotics. It is also useful for maintaining an established route for blood draws or additional treatments as needed.

In contrast, inhalation refers to administering medication through the respiratory tract, which is suitable for conditions affecting the lungs but differs significantly from IV administration. An intramuscular injection involves delivering medication into the muscle tissue, allowing for slower absorption compared to intravenous methods. Oral medication is taken by mouth and processed through the digestive system, which typically results in a delayed onset of action since the drug must be absorbed into the bloodstream through the gastrointestinal tract.
