What does parenteral therapy involve?

Parenteral therapy specifically refers to the administration of fluids and medications directly into the bloodstream through peripheral or central veins. This method bypasses the gastrointestinal tract, allowing for quicker absorption and utilization of medications and nutrients, which can be essential for patients who cannot take oral medications due to conditions such as nausea, vomiting, or severe injuries.

This approach is often utilized in hospital settings for patients who require immediate or precise medical interventions, including those receiving chemotherapy, hydration, or total parenteral nutrition (TPN). By using intravenous methods, healthcare providers can ensure that patients receive efficient and effective treatment tailored to their individual needs.

In contrast, administering medications orally involves the gastrointestinal tract and is not classified as parenteral therapy. Giving fluids and medications through the skin, while a method of drug administration known as transdermal delivery, does not constitute parenteral therapy. Additionally, providing nutritional support via enteral feeding specifically involves delivering nutrition directly to the stomach or intestines, distinct from the intravenous route employed in parenteral therapy.
