The Term Large Volume Parenteral (LVP) Refers To Sterile Preparations Of 250 ML Or More Administered Parenterally
Large Volume Parenteral (LVP) |
Parenteral Medications are
sterile dose forms that are supplied by a different method than the oral route.
The active substance is immediately in contact with tissue or a blood vessel
after being injected into one or more layers of skin. Small volume parenterals
are single or multiple dosage preparations having a volume of 100 ml or less,
whereas Large Volume Parenteral have
a volume greater than 100 ml. Large volume parenteral is administered
intravenously and comes in a bag or bottle. It is used to correct the fluid/electrolyte
balance and supply nourishment, such as dextrose.
Injectable aqueous Medication
products that have been terminally sterilised (by autoclave) and packaged in
single dose containers typically have a capacity of 100 ml or more are known as
Large
Volume Parenteral (LVPs) (usually up to 1 liter). While the
active medicinal ingredients in large volume parenterals can vary, water is
almost usually the main component. Salts, albumin, dextran, salts ranging from
5% to 50%, and amino acids changing in percentage are typical examples.
Thousands of litres or more are typically the size of production batch sizes.
Applications of Large Volume Parenteral-
·
Fluid Balance Therapy
·
Therapeutic Injection
·
Nutritional Therapy
USP Water for Injection, or
pyrogen-free water that complies with the requirements of the monograph in the
most recent edition of the United States Pharmacopoeia, must be used for
product makeup and the final rinse of containers and equipment. There are many
instances in which suitable liquid filters are used in the production of LVPs.
They help prepare pharmaceutical-grade fluids for cleaning and product makeup,
as well as for last filtration to reduce particle and bioburden just before
filling and terminal sterilising. The flow diagram that is attached shows a
typical pharmaceutical water system. Early in the process, effective
pharmaceutical grade depth filters can stop the fouling of downstream
components.
