Parenteral preparations are administered to a patient by injection. The medicine may be injected into the vascular system, into muscle or soft tissue to provide a systemic action, or into an anatomical space such as a joint or into a particular organ to provide a local action.
How is parenteral administered?
Parenteral drug administration means any non-oral means of administration, but is generally interpreted as relating to injecting directly into the body, bypassing the skin and mucous membranes.

- Subcutaneous (under the skin)
- Intramuscular (in a muscle)
- Intravenous (in a vein)
- Intrathecal (around the spinal cord)
How is medicine administered by a parenteral route?
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.

Why is the parenteral route used?
Generally, parenteral is the most reliable, direct and rapidly absorbed way of administering medications. This is used when more complete and faster absorption of a drug is needed.
Where are IV injections given?
With standard IV administration, a needle is usually inserted into a vein in your wrist, elbow, or the back of your hand. The catheter is then pushed over the needle. The needle is removed, and the catheter remains in your vein. All IV catheters are typically given in a hospital or clinic.

What is TPN and how is it administered?
TPN is a mixture of nutrients put directly into your vein. Your mixture will contain whatever nutrients your body needs and may also include some medications. It’s used to help people who can’t get enough nutrients through eating alone. You will get TPN through a central venous catheter (CVC).
How TPN is formulated?
TPN is made up of two components: amino acid/dextrose solution and a lipid emulsion solution (see Figure 8.9). It is ordered by a physician, in consultation with a dietitian, depending on the patient’s metabolic needs, clinical history, and blood work.
Why is TPN administered through a central line?
Historically, total parenteral nutrition (TPN) has been administered by the central venous route because of the rapid development of thrombophlebitis when TPN solutions are administered into peripheral veins. … By avoiding central venous catheterization, TPN can be made safer.
How are parenteral preparation evaluated?
There are mainly seven quality control tests for parenterals are performed : Leaker test Pyrogen test Particulate test Sterility test Clarity test. Closure integrity test Weight variation test or content uniformity test.
What are the types of parenteral preparation?
Parenteral preparations include solutions, suspensions, emulsions, powders, and gels.
What is parenteral packaging?
Parenteral packaging is a method that allows the medicine or other fluid to keep its potency and therapeutic effectiveness intact throughout the shelf life or till the time the drug is administered.

Intradermal (ID) injections have the longest absorption time of all parenteral routes because there are fewer blood vessels and no muscle tissue. These types of injections are used for sensitivity testing because the patient’s reaction is easy to visualize and the degree of reaction can be assessed.
