PHYSIOSOL is a sterile, non-pyrogenic isotonic solution of electrolytes (sodium, potassium, calcium, magnesium, chloride, acetate, and gluconate) in water for injection. It serves as a source of water and electrolytes to expand extracellular fluid volume and maintain osmotic balance. The acetate and gluconate ions are metabolized to bicarbonate, providing an alkalinizing effect.
Replacement of extracellular fluid and electrolytes; provides buffering capacity via bicarbonate precursor (acetate) and maintains physiological p H.
Intravenous solution for fluid and electrolyte replacement in patients with isotonic or hypotonic dehydration,Maintenance of fluid and electrolyte balance during surgery or in postoperative patients,Vehicle for administration of compatible medications
Intravenous replacement of intravascular volume and electrolytes in patients with normal or slightly acidic p H,Maintenance of fluid and electrolyte balance during surgery or in critical care,Correction of hypovolemia when isotonic fluid administration is appropriate
Intravenous infusion; dose based on fluid and electrolyte requirements; typical adult dose: 500-1000 m L/h as needed to maintain hydration and electrolyte balance.
Intravenous infusion, rate adjusted based on clinical status and electrolyte needs; typical adult dose is 500-1000 m L over 1-2 hours.
Not applicable (physiologic solution); infused electrolytes and water distribute and are eliminated with kinetics dependent on renal function; terminal half-life reflects water turnover (~3-6 days in healthy adults).
Not applicable; components follow first-order kinetics with rapid redistribution. Lactate half-life ~15-30 minutes (hepatic metabolism).
The acetate and gluconate ions are metabolized in the liver and peripheral tissues, primarily via the tricarboxylic acid cycle, to bicarbonate. Electrolytes (sodium, potassium, calcium, magnesium, chloride) are not metabolized but are excreted or reabsorbed as per physiological needs.
Acetate is metabolized primarily in the liver and muscles to bicarbonate.
Renal excretion of water and electrolytes; >95% of administered volume is excreted unchanged by kidneys within 24 hours; minimal (<5%) fecal or biliary elimination.
Primarily renal; >95% of infused ions (sodium, chloride, lactate, calcium, magnesium) are excreted unchanged in urine. Biliary/fecal elimination negligible (<1%).
Negligible (<1%); electrolytes are not bound to plasma proteins.
Negligible (<1%); ions are free in plasma (no significant protein binding).
Approximately 0.55 L/kg (total body water); distributes into extracellular fluid (0.2 L/kg) and intracellular water (0.4 L/kg).
0.4 L/kg; distributes mainly in extracellular fluid (ECF).
Intravenous: 100%; oral: 100% (but not relevant as product is for IV use only).
100% (intravenous); not absorbed orally.
No dose adjustment required; monitor serum electrolytes and fluid balance closely in renal impairment; adjust infusion rate based on renal function to avoid fluid overload.
Contraindicated in oliguric or anuric renal failure; in GFR <30 m L/min, avoid use or monitor electrolytes closely; no specific GFR-based dose adjustment.
No specific dose adjustment required; monitor serum electrolytes and acid-base balance in severe hepatic impairment.
No specific Child-Pugh based adjustments; use with caution in hepatic impairment due to risk of fluid overload.
Intravenous infusion; dosing based on body weight; typical dose: 10-20 m L/kg for acute replacement, then adjust based on maintenance requirements; monitor electrolyte levels.
Weight-based dosing: 5-10 m L/kg intravenous infusion over 1-2 hours, not to exceed 30 m L/kg/day.
Use with caution; start with lower end of dosing range; monitor for fluid overload, electrolyte disturbances, and renal function due to age-related changes.
Use with caution due to increased risk of fluid overload and electrolyte imbalance; adjust rate and volume based on renal function and comorbidities, typical initial dose 500 m L over 2-3 hours.
Not for injection into the epidural, intrathecal, or intra-arterial spaces. Do not administer if solution contains visible particulate matter or is discolored. Use only if solution is clear and container is undamaged.
None.

No specific food interactions. However, consider overall fluid and electrolyte intake from diet, especially sodium and potassium, to avoid imbalances.
No food interactions are relevant as Physiosol p H 7.4 is not ingested. It is used exclusively for topical irrigation during medical procedures.
Physiosol in plastic container is a sterile, non-pyrogenic isotonic solution of electrolytes and water. It contains no known teratogenic agents. There are no adequate and well-controlled studies in pregnant women. Animal reproduction studies have not been conducted with this solution. Therefore, it should be used during pregnancy only if clearly needed. No specific fetal risks have been identified for any trimester when used as directed.
Physiosol p H 7.4 (balanced electrolyte solution) is considered low risk for teratogenicity. There are no known fetal risks associated with its use in any trimester, as it is a physiological solution. However, large volumes or rapid administration could theoretically cause maternal electrolyte imbalances, which may indirectly affect the fetus.
Safety in breastfeeding has not been established. Since Physiosol is a balanced electrolyte solution, it is unlikely to pose significant risk to the nursing infant. However, caution is advised. The milk-to-plasma (M/P) ratio is not available.
Physiosol p H 7.4 is compatible with breastfeeding. No M/P ratio is available; however, components are normal plasma constituents and unlikely to be excreted into breast milk in clinically significant amounts.
No specific dosing adjustments are required for pregnancy based on pharmacokinetic changes. However, pregnant patients may have increased plasma volume, and fluid and electrolyte requirements should be individualized. Caution is advised in preeclampsia or conditions with fluid overload.
No specific dose adjustment is required for pregnancy. However, consider increased plasma volume and glomerular filtration rate in pregnancy; standard dosing is appropriate, but monitor for volume overload.
Physiosol in plastic container is a balanced electrolyte solution for intravenous administration, primarily used for replacement of extracellular fluid losses. Monitor for signs of fluid overload, especially in patients with heart failure or renal impairment. The plastic container may leach phthalates; use with caution in neonates and pregnant women. Do not administer if solution is discolored or contains particulate matter.
Physiosol p H 7.4 is a balanced crystalloid solution used for irrigation, not for systemic administration. In the operating room, it is preferred for peritoneal lavage due to its neutral p H, which minimizes tissue irritation. Do not use for intravenous infusion; verify labeling to avoid confusion with IV solutions. Warm to body temperature before use to prevent hypothermia during large-volume irrigation.
This solution is given intravenously to replace fluids and electrolytes.,Report any signs of allergic reaction, such as rash, itching, or difficulty breathing.,Notify your healthcare provider if you experience swelling, shortness of breath, or rapid weight gain.,Do not stop the infusion without consulting your doctor.
This solution is used to rinse body cavities during surgery, not for intravenous use.,You may feel a cooling sensation during irrigation; this is normal.,Report any signs of infection at the surgical site, such as redness, swelling, or discharge.,Do not attempt to use this solution at home; it is for hospital use only.
