PHYSIOSOL™ IRRIGATION
(sodium chloride, sodium acetate anhydrous, sodium gluconate, potassium chloride, and magnesium chloride) Irrigant
Balanced Electrolyte Solution for Irrigation
For All General Irrigation, Washing and Rinsing Purposes
Not for Injection By Usual Parenteral Routes
Semi-rigid Irrigation Container
DESCRIPTION
PhysioSol™ is a sterile, nonpyrogenic solution of electrolytes in water for injection intended only for
sterile irrigation, washing and rinsing purposes.
Each 100 mL of PhysioSol™ Irrigation contains sodium chloride 526 mg, sodium acetate 222 mg,
sodium gluconate 502 mg, potassium chloride 37 mg, magnesium chloride hexahydrate 30 mg. The pH
is 6.0 (5.0 to 6.5) adjusted with hydrochloric acid. The solution is isotonic (294 mOsmol/liter, calc.)
and has the following electrolyte content (mEq/liter): Na+ 140, K+ 5, Mg++ 3, Cl-98, HCO33-50
alternates (27 as acetate and 23 as gluconate).
It contains no bacteriostat, antimicrobial agent or added buffer (except for pH adjustment) and is intended
only for use as single-dose or short procedure irrigation. When smaller volumes are required the
unused portion should be discarded.
PhysioSol™ may be classified as a sterile irrigant, wash, rinse and pharmaceutical vehicle.
Magnesium Chloride, USP is chemically designated magnesium chloride hexahydrate (MgCl2 • 6H2O),
colorless, odorless flakes or crystals very 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 Acetate, USP is chemically designated sodium acetate (C2H3O2Na), colorless crystals or white
crystalline powder or flakes very soluble in water. It has the following structural formula:
Sodium gluconate is chemically designated C6H11NaO7 , the normal sodium salt of gluconic acid
soluble in water. It has the following structural formula:
Water for Injection, USP is chemically designated H2O.
The semi-rigid container is fabricated from a specially formulated polyolefin. It is a copolymer of
ethylene and propylene. The container requires no vapor barrier to maintain the proper drug
concentrations.
Solutions in contact with the plastic container may leach out certain chemical components from the
plastic in very small amounts; however, biological testing was supportive of the safety of the plastic
container materials.
Exposure to temperatures above 25°C/77°F during transport and storage will lead to minor losses in
moisture content. Higher temperatures lead to greater losses. It is unlikely that these minor losses will
lead to clinically significant changes within the expiration period.
