Parenteral drug administration can be taken literally to mean any non-oral means of drug administration, but it is generally interpreted as relating to injection directly into the body, by-passing the skin and mucous membranes. The common routes of parenteral administration are intramuscular (IM), subcutaneous and IV.


What does IV mean? IV is the abbreviation for "intravenous." The word "intravenous" is quite properly an adjective. In this guise, it entered the English language around 1849. It means, according to Merriam Webster's Collegiate Dictionary, "situated, performed, or occurring within or entering by way of a vein."

what is intravenous route of drug administration?

Intravenous (IV) is a method of administering concentrated medications (diluted or undiluted) directly into the vein using a syringe through a needleless port on an existing IV line or a saline lock. Medications administered by direct IV route are given very slowly over AT LEAST 1 minute (Perry et al., 2014).

Why is intravenous route used? The intravenous route is the fastest way to deliver medications and fluid replacement throughout the body, because they are introduced directly into the circulation. Intravenous therapy may be used for fluid volume replacement, to correct electrolyte imbalances, to deliver medications, and for blood transfusions.

can IM injection be given IV?

Intramuscular. The intramuscular route is used where effects are desired over a longer period of time than can be expected after intravenous injection, for drugs that are too irritant to be given subcutaneously, or for oily solutions, which cannot be given intravenously.

What are the advantages of intravenous route of administration? The administration of IV medication offers advantages over other routes of administration. Some of the main advantages include: direct access to the circulatory system, a route for administration of drugs and fluids for patients unable to tolerate oral medications and instant drug action and termination.

which route of drug administration is considered the best overall?

orally

What happens when IV drip is too fast? Complications related to the regulation of fluids include giving too much fluid too rapidly, causing fluid overload. Alternatively, not enough fluid may be given or it's released too slowly. Overload can cause symptoms such as a headache, high blood pressure, anxiety, and trouble breathing.

Which routes are used to administer ophthalmic medications?

Routes of Administration for Ocular Medications. The three primary methods of delivery of ocular medications to the eye are topical, local ocular (ie, subconjunctival, intravitreal, retrobulbar, intracameral), and systemic. The most appropriate method of administration depends on the area of the eye to be medicated.

How do you inject IV? Insert needle with bevel (hole) pointing up This helps with flow and reduces risk of vein damage. Aim in the direction of blood flow Go towards the heart. Flag the needle Push plunger in a little and then pull back until you see blood in needle. This way you know your needle is in right.

Is IM faster than IV?

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.

What are the advantages of intravenous injection?

The advantages of intravenous injection are that the response is very rapid, the dosage of the drug can be easily controlled, and veins are insensitive to irritation by irritant drugs at higher concentration.

What is the difference between IM and IV injection?

Intramuscular injections may be used instead of intravenous injections because some drugs are irritating to veins, or because a suitable vein can't be located. Muscle tissue can also hold a larger volume of medication than subcutaneous tissue.

What are the 3 types of injections?

The three main routes are intradermal (ID) injection, subcutaneous (SC) injection and intramuscular (IM) injection. Each type targets a different skin layer: Subcutaneous injections are administered in the fat layer, underneath the skin. Intramuscular injections are delivered into the muscle.

Why is IV medication more effective?

IV medication is often used because of the control it provides over dosage. This would prevent the drugs from working well when they're finally sent to your bloodstream. Therefore, these drugs would be much more effective if sent directly into your bloodstream by IV administration.

What are the sites of IV injection?

The preferred sites for IV cannulation Hand. Dorsal arch veins. Wrist. Volar aspect. Cubital fossa. Median antecubital, cephalic and basilic veins. Foot. Dorsal arch. Leg. Saphenous vein at the knee.

How fast is sublingual absorption?

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 drugs are given intramuscularly?

Examples of medications that are sometimes administered intramuscularly are: Atropine. Haloperidol (Haldol) Aripiprazole (Abilify) Paliperidone (Invega) Chlorpromazine (Thorazine) Lorazepam (Ativan) Fulvestrant (Faslodex) Codeine.

What are the 6 R's of medication?

something known as the '6 R's', which stands for right resident, right medicine, right route, right dose, right time, resident's right to refuse.
