Questions and Answers

What is the difference between enteral and parenteral administration?

Enteral administration refers to drug administration via the respiratory tract, while parenteral administration refers to drug administration via the gastrointestinal tract

Enteral administration refers to drug administration by injection, while parenteral administration refers to drug administration via the gastrointestinal tract

Enteral administration uses the gastrointestinal tract, while parenteral administration does not (correct)

Enteral administration does not use the gastrointestinal tract, while parenteral administration does

Why do many medicines have to be administered parenterally?

The drug molecule would be rapidly absorbed in the gastrointestinal tract

The drug molecule would be rapidly broken down in the gastrointestinal tract (correct)

The drug molecule would be rapidly excreted in the gastrointestinal tract

The drug molecule would be rapidly metabolized in the gastrointestinal tract

What is the advantage of intravenous injection over oral administration?

Intravenous injection produces an effect much faster than orally administered drugs (correct)

Intravenous injection is more convenient than orally administered drugs

Intravenous injection has fewer side effects than orally administered drugs

Intravenous injection is less painful than orally administered drugs

What is the advantage of intravenous injection over orally administered drugs?

Intravenous injection delivers the drug directly into the circulatory system, where it is then rapidly distributed around the body, producing an effect much faster than orally administered drugs. Signup and view all the answers

What is the advantage of parenteral nutrition over a healthy diet?

Parenteral nutrition provides all the nutrients, vitamins, and trace elements normally obtained from a healthy diet intravenously, which is useful when the gastrointestinal tract is not working. Signup and view all the answers

Study Notes

Reasons for Choosing Parenteral Administration

Enteral administration refers to drug administration via the gastrointestinal tract, while parenteral administration refers to any method of drug administration that does not utilize the gastrointestinal tract, commonly taken to mean drug administration by injection.
Patients would prefer to receive their medication as an oral tablet or liquid to swallow, or as a cream, ointment, or transdermal patch to apply to the skin rather than receive treatment via injection, which can be painful or stressful.
It is often simpler and much cheaper to prepare medicines such as tablets or liquids, particularly given the less stringent requirements for manufacturing premises for these non-sterile products, compared to the costs associated with manufacturing sterile medicines, such as injections, in highly specialized, controlled environments.
Many medicines are administered parenterally because the drug molecule itself would be rapidly broken down in the gastrointestinal tract and would thus become inactivated before it could be absorbed into the circulatory system.
Injectable routes may be chosen to provide a highly localized effect, particularly true when the injection route accesses a particular anatomical area or organ system.
Intravenous injection delivers the drug directly into the circulatory system, where it is then rapidly distributed around the body, producing an effect much faster than orally administered drugs.
Intramuscular injection can delay and prolong the release of the medicine from the injection site into the circulation, allowing for prolonged drug release and less frequent dosing.
The intravenous route of injection is routinely used to administer medication to the unconscious patient who is unable to swallow and in conscious or unconscious patients if the gastrointestinal tract is not working.
Not only are medicines, but fluids for hydration and electrolyte replacement, plus all the nutrients, vitamins, and trace elements normally obtained from a healthy diet supplied by parenteral nutrition provided intravenously.
Examples of intravenous injections include emergency situations where a rapid onset of action is critical, while intra-articular, intra-ocular, and intrathecal injections target specific anatomical areas or organ systems.
Injectable medications are manufactured in highly specialized, controlled environments due to their sterile nature, which increases their cost compared to non-sterile oral medications.
Injectable medications are typically administered by healthcare professionals and require proper training and knowledge of injection techniques and safety protocols.
