Plasma-Lyte R Description
Plasma-Lyte R Injection (Multiple Electrolytes Injection, Type 2, USP) is a sterile, nonpyrogenic isotonic solution in a single dose container for intravenous administration. Each 100 mL contains 640 mg of Sodium Acetate Trihydrate, USP (C2H3NaO2•3H2O); 496 mg of Sodium Chloride, USP (NaCl); 89.6 mg of Sodium Lactate (C3H5NaO3); 74.6 mg of Potassium Chloride, USP (KCl); 36.8 mg of Calcium Chloride, USP (CaCl2•2H2O); and 30.5 mg of Magnesium Chloride, USP (MgCl2•6H2O). It contains no antimicrobial agents. The pH is adjusted with hydrochloric acid. The pH is 5.5 (4.0 to 8.0).
Plasma-Lyte R Injection (Multiple Electrolytes Injection, Type 2, USP) administered intravenously has value as a source of water, electrolytes, and calories. One liter has an ionic concentration of 140 mEq sodium, 10 mEq potassium, 5 mEq calcium, 3 mEq magnesium, 103 mEq chloride, 47 mEq acetate, and 8 mEq lactate. The osmolarity is 312 mOsmol/L (calc). Normal physiologic osmolarity range is approximately 280 to 310 mOsmol/L. Administration of substantially hypertonic solutions may cause vein damage. The caloric content is 11 kcal/L.
The VIAFLEX plastic container is fabricated from a specially formulated polyvinyl chloride (PL 146 Plastic). The amount of water that can permeate from inside the container into the overwrap is insufficient to affect the solution significantly. Solutions in contact with the plastic container can leach out certain of its chemical components in very small amounts within the expiration period, e.g., di-2-ethylhexyl phthalate (DEHP), up to 5 parts per million. However, the safety of the plastic has been confirmed in tests in animals according to USP biological tests for plastic containers as well as by tissue culture toxicity studies.
Plasma-Lyte R - Clinical Pharmacology
Plasma-Lyte R Injection (Multiple Electrolytes Injection, Type 2, USP) has value as a source of water and electrolytes. It is capable of inducing diuresis depending on the clinical condition of the patient.
