Study Notes
Parenteral Products Overview
- "Parenteral" derives from the Greek "para enteron," meaning "to avoid the intestines."
- Defined as preparations intended for injection through the skin into blood vessels, organs, tissues, or lesions, ensuring sterility and being pyrogen-free.
- Classified based on the route of administration and volume.
Classification by Route of Administration
-
Common Routes:
- Intravenous (IV): Direct injection into a vein; suitable for all drug classes; includes IV bolus for rapid administration; rate of absorption order: IV > IM > SC > ID.
- Intramuscular (IM): Administered into muscle tissue for moderate absorption time.
- Subcutaneous (SC): Injection into the fatty tissue under the skin.
- Intradermal (ID): Injection into the dermis, mainly for diagnostic tests; volume usually ≤ 0.1 mL.
-
Specialized Routes:
- Administered by trained physicians due to higher risks.
- Intra-arterial: Direct injection into arteries to target specific organs; used for diagnostic angiography and limited use in chemotherapy.
- Intra-articular: Injection into joint spaces for antibiotics, analgesics, and anti-inflammatory treatment.
- Intracisternal: Injection into the cisternal space at the base of the brain, primarily for diagnostics.
- Intraventricular: Injection into brain ventricles for treating infections and malignancies.
- Intrathecal: Injection into the spinal canal for anesthesia, chemotherapy, and pain management.
- Epidural: Injection into the epidural space for regional anesthesia using a Tuohy needle.
- Intracardiac: Direct injection into heart chambers; primarily for emergencies like cardiac arrest.
- Intraocular: Injection into eye chambers; details in ophthalmic chapters.
- Intraosseous: Injection into bone marrow, often used for emergency situations when IV access fails.
- Intralymphatic: Injection into lymph nodes or vessels, used in diagnostics and immunotherapy.
Classification by Volume
-
Small Volume Parenterals (SVPs):
- Volumes below 100 mL, can be single or multiple dose.
- Preservatives added for multiple-dose preparations; total volume must be <30 mL.
-
Large Volume Parenterals (LVPs):
- Volumes above 100 mL, up to 5000 mL; intended for single-dose usage.
- Must be preservative-free and discarded if unused; mostly administered via IV.
- Infusion modes include continuous, discontinuous, volume over time, and dose over time.
- Administered via peripheral veins or central lines.
Uses of Large Volume Parenterals
- Supply electrolytes and nutrients.
- Prevent tissue dehydration.
- Restore blood volume.
- Dilute toxic materials.
- IV admixture for premixed injectable drugs.
Common and Specialized Large Volume Parenterals
-
Common LVPs:
- Lactated Ringer's injection.
- 0.9% Sodium Chloride injection.
- 5% Dextrose injection.
-
Specialized LVPs:
- Hyperalimentation solutions for total parenteral nutrition (TPN).
- Cardioplegic solutions.
- Dialysis solutions (peritoneal and hemodialysis).
- Irrigating solutions (not categorized as parenteral products).
Hyperalimentation Solutions
- Used in TPN, providing nutrients via a central venous catheter.
- Recommended for patients not taking anything orally for over five days.
- Indications include long-term coma, severe gastrointestinal syndromes, and esophageal obstruction.
