Description
Ringer's Irrigation USP is a sterile, nonpyrogenic, solution of electrolytes in water for injection intended only for sterile irrigation, washing and rinsing purposes.
Each 100 mL contains:
Sodium Chloride USP 0.86 g; Potassium Chloride USP 0.03 g
Calcium Chloride Dihydrate USP 0.033 g; Water for Injection USP qs
pH: 5.8 (5.0-7.5). The solution is isotonic (310 mOsmol/liter, calc.) and has the following electrolyte content (mEq/liter): Na+ 147; K+ 4 Ca++ 4.5; Cl− 156
The solution contains no bacteriostat, antimicrobial agent or added buffer and is intended only for use as a single-dose or short procedure irrigation. When smaller volumes are required the unused portion should be discarded. Ringer's Irrigation USP may be classified as a sterile irrigant, wash, rinse and pharmaceutical vehicle.
The formulas of the active ingredients are:
| Ingredients | Molecular Formula | Molecular Weight |
|---|---|---|
| Sodium Chloride USP | NaCl | 58.44 |
| Potassium Chloride USP | KCl | 74.55 |
| Calcium Chloride Dihydrate USP | CaCl2•2H2O | 147.01 |
The plastic container is a copolymer of ethylene and propylene formulated and developed for parenteral drugs. The copolymer contains no plasticizers and exhibits virtually no leachability. The plastic container is also virtually impermeable to vapor transmission and therefore, requires no overwrap to maintain the proper drug concentration. The safety of the plastic container has been confirmed by biological evaluation procedures. The material passes Class Vl testing as specified in the U.S. Pharmacopeia for Biological Tests — Plastic Containers. These tests have shown that the container is nontoxic and biologically inert.
The PIC™ Container is PVC-free and DEHP-free.
