Vía parenteral

The parenteral route is one in which the drugs reach the internal environment without being absorbed by the digestive system.

The main routes are parenteral, intradermal, subcutaneous, intramuscular and intravenous route, although there are others such as intracardiac or intra-arterial.

For intravenous access is necessary to use needles of different sizes and with different functions (needle, intravenous catheter ...) according to road type and time used or volume of drug infusion (continuous infusion single dose ...).

The parenteral route is the fastest and the one that achieves greater efficacy.
