LACTATED RINGERS

These products are sterile, nonpyrogenic solutions each containing isotonic concentrations of electrolytes (without dextrose) in water for injection. The solutions containing only electrolytes are isotonic. They are administered by intravenous infusion for parenteral replacement of extracellular losses of fluid and electrolytes, with or without minimal carbohydrate calories. Each 100 mL of Lactated Ringer's Injection, USP contains sodium chloride 600 mg, sodium lactate, anhydrous 310 mg, potassium chloride 30 mg and calcium chloride, dihydrate 20 mg. May contain hydrochloric acid and/or sodium hydroxide for pH adjustment. A liter provides 9 calories (from lactate), sodium (Na + ), 130 mEq, potassium (K + ) 4 mEq, calcium (Ca ++ ) 3 mEq, chloride (Cl − ) 109 mEq and lactate [CH 3 CH(OH) COO − ] 28 mEq. The electrolyte content is isotonic (273 mOsmol/liter, calc.) in relation to the extracellular fluid (approx. 280 mOsmol/liter). The pH of the solution is 6.6 (6.0 − 7.5). The solutions contain no bacteriostat, antimicrobial agent or added buffer (except for pH adjustment) and each is intended only for use as a single-dose injection. When smaller doses are required the unused portion should be discarded. The solutions are parenteral fluid, nutrient and/or electrolyte replenishers. Calcium Chloride, USP is chemically designated calcium chloride, dihydrate (CaCl 2 • 2 H 2 O), white fragments or granules freely soluble in water. Potassium Chloride, USP is chemically designated KCl, a white granular powder freely soluble in water. Sodium Chloride, USP is chemically designated NaCl, a white crystalline powder freely soluble in water. Sodium Lactate, USP is chemically designated monosodium lactate [CH 3 CH(OH)COONa], a 60% aqueous solution miscible in water. It has the following structural formula: Water for Injection, USP is chemically designated H 2 O. The flexible plastic container is fabricated from a specially formulated polyvinylchloride. Water can permeate from inside the container into the overwrap but not in amounts sufficient to affect the solution significantly. Solutions inside the plastic container also can leach out certain of their chemical components in very small amounts before the expiration period is attained. However, the safety of the plastic has been confirmed by tests in animals according to USP biological standards for plastic containers. structural formula sodium lactate

These solutions are indicated for parenteral replacement of extracellular losses of fluid and electrolytes, with or without minimal carbohydrate calories, as required by the clinical condition of the patient.

The dose is dependent upon the age, weight and clinical condition of the patient. Drug Interactions Additives may be incompatible. Consult with pharmacist, if available. When introducing additives, use aseptic technique, mix thoroughly and do not store. The presence of calcium limits their compatibility with certain drugs that form precipitates of calcium salts, and also prohibits their simultaneous infusion through the same administration set as blood because of the likelihood of coagulation. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. See PRECAUTIONS .

Solutions containing lactate are NOT FOR USE IN THE TREATMENT OF LACTIC ACIDOSIS.

Reactions which may occur because of the solution or the technique of administration include febrile response, infection at the site of injection, venous thrombosis or phlebitis extending from the site of injection, extravasation and hypervolemia. If an adverse reaction does occur, discontinue the infusion, evaluate the patient, institute appropriate therapeutic countermeasures and save the remainder of the fluid for examination if deemed necessary.
