What is a parenteral method of Drug Administration?
Dec 12, 2022 · The parenteral route refers to the intravenous administration of nutrition and medications by bypassing the gastrointestinal system. The parenteral route of drug delivery includes four types: subcutaneous , intramuscular, intravenous , and intrathecal administration.
Administering medication by the parenteral route is defined as medications placed into the tissues and the circulatory system by injection. There are several reasons why medications may be prescribed via the parenteral route.

Aug 23, 2023 · Intravenous injection is the most common parental route of medication administration and can bypass the liver's first-pass metabolism. Given their superficial location on the skin, peripheral veins provide easy access to the circulatory system and are often utilized in the parenteral administration of medications.

- Advantages of Parenteral Route of Drug Administration
This involves the administration of a drug within the vertebral column. The two most frequent routes for intraspinal drug delivery are epidural route and intrathecal route. These routes are used primarily for anesthesia (e.g. lidocaine, bupivacaine) and pain management (e.g. opioid analgesic). a. Epidural route:This is a method of drug administrati...
Intraarterial route involves direct administration to an artery, generally for local effects over irrigated organs or tissues. For example, antineoplastic injected in the surroundings of the tumor, with a decrease of systemic adverse effects. It is also useful for the administration of vasodilators in arterial embolisms or contrast media for arteri...
This involves direct administration to the cerebral ventricles. This route bypasses the blood-brain barrier and other mechanisms that limit drug distribution into the brain, allowing high drug concentrations to enter the central compartment.

This route of drug administration is used only as an emergency route during a cardiac arrest (adrenaline injection into cardiac chambers) due to the serious injuries that may be caused by the needle. It involves direct administration of drugs into the heart.
This route involves administration of drugs within the skin, at the dermis level, generally in the ventral zone of the forearm. Due to the extremely low blood supply to the dermis, intradermic administration implies almost null systemic absorption of the drug. It is usually used for vaccines (e.g., BCG vaccines) and for local anesthesia, as well as...
This involves direct administration on a joint, generally for local effects. For example, anti-inflammatory corticosteroids for arthritis.
Intralymphatic route involves administration of drugs into a lymph node or a vessel. It is used, for example, for the administration of stem cells during the treatment of autoimmune diseases, antitumoural therapy, and/or for diagnosis purposes (contrast reagents injection).

This involves direct administration of drugs into the marrow of a bone. It can safely be used to administer any intravenous drug or fluid required during pediatric resuscitation since the vascular bed of these bones quickly transports the drug to the rest of the body. The onset of action and drug levels are comparable to those achieved when drugs a...
The injection is given in the peritoneal space leading to a high absorption rate credited to the available large surface area. This route may cause infections in the peritoneal cavity and is painful and risky.
Advantages of parenteral administration are as follows: 1.Parenteral route of drug administration is the route of choice for drugs that have poor absorption in the GIT and drugs like insulin which are unstable in the gastrointestinal tract (GIT) and/or that are unstable in the GIT (e.g. insulin, heparin). 2.Parenteral routes could be used in uncons...
Administration by injection (parenteral administration) includes the following routes: Subcutaneous (under the skin) Intramuscular (in a muscle) Intravenous (in a vein) Intrathecal (around the spinal cord) A drug product can be prepared or manufactured in ways that prolong drug absorption from the injection site for hours, days, or longer.
1.11: Routes of Drug Administration: Parenteral. The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
