Quick Answer: What Are The Advantages Of Oral Route Of Administration?

Why is the oral route of administration safer?

Because the oral route is the most convenient and usually the safest and least expensive, it is the one most often used.

However, it has limitations because of the way a drug typically moves through the digestive tract.

For drugs administered orally, absorption may begin in the mouth and stomach..

What are the common injectable routes of administration?

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)

Which route of administration is not by mouth?

Parenteral route Parenteral administration refers to any non-oral means of medicine administration, but is generally interpreted as relating to injecting directly into the body, bypassing the skin and mucous membranes.

What are the 4 enteral routes of administration?

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.

How many types of IV administration are there?

Crystalloid IV solutions contain small molecules that flow easily across semipermeable membranes. They are categorized according to their relative tonicity in relation to plasma. There are three types: isotonic, hypotonic, and hypertonic.

What drug is IV?

Intraveneous (IV) drug use is the injection of chemicals into the body via a hypodermic needle into a vein. Drugs can also be injected under the skin (also called “skin popping”) or directly into the muscle (intramuscular injection).

What is the most common route of administration?

Oral administration This is the most frequently used route of drug administration and is the most convenient and economic. Solid dose forms such as tablets and capsules have a high degree of drug stability and provide accurate dosage.

What are the advantages of intravenous route of administration?

The intravenous route has a number of advantages. Drug is delivered immediately upon the completion of a response requirement and since delivery is into a vein, there is a rapid onset of drug effects. Such immediacy results in rapid acquisition and strong maintenance of behavior.

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).

What is a disadvantage to the oral route for medication administration?

Although solid-dose forms such as tablets and capsules have a high degree of drug stability and provide accurate dosage, the oral route is problematic because of the unpredictable nature of gastrointestinal absorption.

Why is oral route preferred?

The oral administration route is preferred over the various other administration routes of drug delivery due to the many advantages it exhibits. These advantages include safety, good patient compliance, ease of ingestion, pain avoidance, and versatility to accommodate various types of drugs (Sastry et al., 2000).

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.

What is characteristic of the oral route?

Oral administration includes: Buccal, dissolved inside the cheek. Sublabial, dissolved under the lip. Sublingual administration (SL), dissolved under the tongue, but due to rapid absorption many consider SL a parenteral route.

What are the advantages of enteral administration?

Advantages are that a drug that is irritant to the stomach can be given by suppository (aminophylline, indomethacin); the route is suitable in vomiting, motion sickness, migraine or when a patient cannot swallow, and when cooperation is lacking (sedation in children).

Which is faster IV or IM?

IV injections take effect the fastest, and the effects also dissipate the fastest. IM injections take effect the next fastest, and SQ injections take the longest to take effect.

What is the fastest route of absorption for a drug?

The fastest route of absorption is inhalation, and not as mistakenly considered the intravenous administration. Absorption is a primary focus in drug development and medicinal chemistry, since the drug must be absorbed before any medicinal effects can take place.

How many routes of drug administration are there?

9.5. For small therapeutic molecules, various routes for drug administration are parenteral (intravenous, intramuscular, and subcutaneous), oral, nasal, ocular, transmucosal (buccal, vaginal, and rectal), and transdermal.
