Elliotts B - Sodium Cation, Sodium Bicarbonate, Anhydrous Dextrose, Magnesium Sulfate, Potassium Chloride, Calcium Chloride, Sodium Phosphate injection prescribing information
INDICATIONS AND USAGE
Elliotts B Solution is indicated as a diluent for the intrathecal administration of methotrexate sodium and cytarabine for the prevention or treatment of meningeal leukemia or lymphocytic lymphoma.
DOSAGE AND ADMINISTRATION
See product labeling for methotrexate sodium and cytarabine.
Elliotts B Solution is intended for intrathecal administration only. Elliotts B Solution does not contain antibacterial preservatives and introduction of contaminated solutions into the cerebrospinal fluid may have extremely serious consequences. Therefore, administration of intrathecal solutions should be accomplished as soon as possible after preparation.
A sterile filter-needle should be used to withdraw the contents of the ampule.
Intrathecal drug products should be inspected visually for particulate matter and discoloration prior to administration.
Preparation and Administration Precautions
Elliotts B Solution is a diluent for the cytotoxic anticancer agents, methotrexate sodium and cytarabine. Care should be exercised in the handling and preparation of infusion solutions with these products. (See product labeling for methotrexate sodium and cytarabine.)
CONTRAINDICATIONS
None known.
ADVERSE REACTIONS
Adverse reactions may occur with any given intrathecal injection due to the chemotherapy or the technique of intrathecal administration. (See product labeling for methotrexate sodium and cytarabine.)
Preservative-free methotrexate sodium and cytarabine should be used to minimize adverse reactions due to preservatives.
If an adverse reaction does occur, discontinue the administration, evaluate the patient, institute appropriate therapeutic countermeasures and, if possible, save the remainder of the unused solution(s) for examination.

CLINICAL PHARMACOLOGY
Elliotts B Solution provides a buffered salt solution for use as a diluent for the intrathecal administration of methotrexate sodium and cytarabine. It has been demonstrated that Elliotts B Solution is comparable to cerebrospinal fluid in pH, electrolyte composition, glucose content, and osmolarity:

Solution | Na + mEq/L | K + mEq/L | Ca ++ mEq/L | Mg ++ mEq/L | HCO 3 - mEq/L | Cl - mEq/L | pH | Phosphorus mg/dL | Glucose mg/dL |
Cerebrospinal Fluid | 117-137 | 2.3-4.6 | 2.2 | 2.2 | 22.9 | 113-127 | 7.31 | 1.2-2.1 | 45-80 |
Elliotts B Solution | 149 | 4 | 2.7 | 2.4 | 22.6 | 132 | 6.0-7.5 | 2.3 | 80 |
The approximate buffer capacity of Elliotts B Solution is 1.1 X 10 -2 equivalents when the challenge solution is 0.01 N HCl and 7.8 X 10 -3 equivalents when the challenge solution is 0.01 N NaOH. 1
Compatibility studies with methotrexate sodium and cytarabine indicate these drugs are physically compatible with Elliotts B Solution.
