2. LEARNING OBJECTIVES
• Familiarize concept of parenteral with characteristics of LVPs.
• Understand types of LVPs with specialised LVPs.
• Discuss concept of intravenous and nonintravenous LVPs.
3. Definition
"Parenteral" derived from two Greek words ‘para’ beside
and ‘enteron’ meaning intestine.
Parenteral dosage forms administered directly into body tissues rather
than through the intestine with the help of an injection.
Active substances are administered using gravity, or force directly into
blood vessels, organs or tissues.
As per USP LVP solutions applies to a single dose injection.
It is intended for intravenous use.
It is packaged in containers labelled as containing more than 100 ml.
4. Characteristics of Large Volume Parenterals
It should be sterile, nonpyrogenic, free from particulate matters.
The volume with single units should be more than 100 ml.
It should not contain any preservative.
The volume does not exceed 1000ml in IV LVP’S
Nonintravenous LVP volume may exceed 1000 ml.
(Example: Irrigation and Dialysis solution)
It should be isotonic to minimise damage to blood vessels and blood cells.
Hypertonic solution may be administered efficiently .
Small quantity of hypertonic solution may be administered in a peripheral
vein
Large quantity of hypertonic solution are administered which inserted in a
large central veins as subclavian vein or internal jugular vein.
5. REFLECTION SPOT
What are the various types of large volume parenterals? What are
various specilaised LVPs?
16. INTRA VENOUS ADMIXTURES
one or more sterile dry products added to an IV fluid.
Additive is SVP added to large volume parenteral
It is used for drugs that intended for continuous infusion.
Drugs that may cause irritation and toxicity given by direct IV
injection.
Laminar air flow unit with HEPA filter efficiency 99.97%.(0.3
µm particle)
Personnel handling admixtures should wear gloves and mask.
The process for mixing will deviate.
Totally depend on which IV fluid packaging system utilised by
the hospital.
17. IRRIGATION SOLUTION
To irrigate, flush and in cleansing body cavities and wounds.
Irrigating solution should not be used parentally .
Irrigating solution must be sterile, pyrogen free.
Handled with same care as parenteral solution.
Examples:
Acetic acid irrigation USP
Neomycin and Polymyxin B sulfates solution for irrigation, USP
Ringers Irrigation, USP
Sodium Chloride Irrigation USP
Sterile water for injection USP
