Drugs administered by inhalation through the mouth must be atomized into smaller droplets than those administered by the nasal route, so that the drugs can pass through the windpipe (trachea) and into the lungs.
What route is an inhaler given?
Albuterol is only administered using
the inhalation route
. It is used for treating asthma/COPD and has the best effects when directly administered into the lungs. Insulin is only given via subcutaneous injection. It cannot be taken orally because the digestive tract destroys its structure and makes it inactive.
What are the 8 routes of drug administration?

- Sublingual. …
- Rectal administration. …
- Topical administration. …
- Parenteral administration. …
- Intravenous injection.
What is the route of medication administration?
A medication administration route is often classified by
the location at which the drug is applied
, such as oral or intravenous. The choice of routes in which the medications are applied depends not only on the convenience but also on the drug’s properties and pharmacokinetics.
Is intranasal a parenteral route?
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.
Which route of administration has the slowest onset of action?
A subcutaneous injection
is administered under the skin into the fat layer just below the dermis of the skin. The absorption from the subcutaneous route is slow and sustained action as the tissue sites have fewer blood vessels. It has a slower action compared to intravenous but faster than an intradermal route.
Does a drug’s route of administration matter?
Since the bioavailability of a drug is
directly dependent
on the rate and extent of drug absorption at the site of administration, factors affecting drug absorption, including the route of administration directly affect the bioavailability of that drug.
What are the 4 basic rules for medication administration?
The “rights” of medication administration include
right patient, right drug, right time, right route, and right dose
. These rights are critical for nurses.
Which route of administration is used most often?
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.
Which is the best route of drug administration?
Intravenous administration
is the best way to deliver a precise dose quickly and in a well-controlled manner throughout the body. It is also used for irritating solutions, which would cause pain and damage tissues if given by subcutaneous or intramuscular injection.
Why is oral route preferred?
The oral route is the most common route for drug administration. It is the most preferred route, due to its advantages, such as
non-invasiveness, patient compliance and convenience of drug administration
.
How are drugs categorized?
Drugs can be categorized
based upon their effects on users
. There are essentially seven different drug types, each with its own set of characteristics, effects and dangers. Categories include stimulants, depressants, hallucinogens, dissociatives, opioids, inhalants and cannabis.
What are the 5 R’s of medication?
To ensure safe drug administration, nurses are encouraged to follow the five rights (‘R’s;
patient, drug, route, time and dose
) of medication administration to prevent errors in administration.
What is difference between enteral and parenteral routes of administration?
Enteral nutrition is administered through a feeding tube placed into the stomach or intestines. Parenteral nutrition is administered through a
traditional intravenous
(IV) line or via a central IV surgically placed during an outpatient procedure.
What is the fastest route of absorption for a drug?
The fastest route of absorption is
inhalation
. Absorption is a primary focus in drug development and medicinal chemistry, since a drug must be absorbed before any medicinal effects can take place.
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.
