Quick Answer: What Are The Four Enteral Routes Of Administration?

Is buccal an enteral route?

The routes of absorption include enteral, absorbed by the gastrointestinal tract, and parenteral, absorbed outside the gastrointestinal tract.

Oral, buccal, sublingual, and rectal are the most common enteral routes of administration..

Is sublingual faster than oral?

Peak blood levels of most products administered sublingually are achieved within 10‐15 minutes, which is generally much faster than when those same drugs are ingested orally. Sublingual absorption is efficient. The percent of each dose absorbed is generally higher than that achieved by means of oral ingestion.

What are the two major routes of drug administration?

When the systemic absorption of a drug is desired, medications are usually administered by two main routes: the enteral route and the parenteral route. Enteral route involves absorption of the drug via the gastrointestinal tract and includes oral, sublingual, and rectal administration.

What are parenteral routes of administration?

There are five commonly used routes of parenteral (route other than digestive tract) administration: subcutaneous (SC/SQ), intraperitoneal (IP), intravenous (IV), intrader- mal (ID), and intramuscular (IM). Not all techniques are appropriate for each species.

Which drug administration route is fastest?

Intravenous (IV) It is the fastest and most certain and controlled way. It bypasses absorption barriers and first-pass metabolism.

Which is faster IV or IM?

IV drug administration achieves high plasma concentrations rapidly in plasma and tissues. Muscles are very vascular structures, and IM absorption occurs by drug diffusion from interstitial fluid and capillary membranes into plasma, and so onset of action is longer than IV injection.

Which drug administration route is the least predictable?

The amount of drug absorbed in the rectal / vaginal route is usually less than if the drug were administered orally. The absorption of drugs administered rectally is unpredictable and can vary among patients.

What is the importance of enteral drug delivery route?

Oral (PO) administration is the most frequently used route of administration because of its simplicity and convenience, which improve patient compliance. Bioavailability of drugs administered orally varies greatly.

How is the route of administration of medication determined?

A route of administration in pharmacology and toxicology is the path by which a drug, fluid, poison, or other substance is taken into the body. Routes of administration are generally classified by the location at which the substance is applied. Common examples include oral and intravenous administration.

Is parenteral the same as IV?

The common parenteral routes are intramuscular (IM), subcutaneous (SC) and intravenous (IV). Box 1 outlines the advantages and disadvantages of parenteral routes.

What is the difference between enteral and parenteral routes?

Enteral administration involves the esophagus, stomach, and small and large intestines (i.e., the gastrointestinal tract). Methods of administration include oral, sublingual (dissolving the drug under the tongue), and rectal. Parenteral administration is via a peripheral or central vein.
