PHYSIOSOL PH 7.4 IN PLASTIC CONTAINER
Clinical safety rating
cautionComprehensive clinical and safety monograph for PHYSIOSOL PH 7.4 IN PLASTIC CONTAINER (PHYSIOSOL PH 7.4 IN PLASTIC CONTAINER).
Replacement of extracellular fluid and electrolytes; provides buffering capacity via bicarbonate precursor (acetate) and maintains physiological pH.
| Metabolism | Acetate is metabolized primarily in the liver and muscles to bicarbonate. |
| Excretion | Primarily renal; >95% of infused ions (sodium, chloride, lactate, calcium, magnesium) are excreted unchanged in urine. Biliary/fecal elimination negligible (<1%). |
| Half-life | Not applicable; components follow first-order kinetics with rapid redistribution. Lactate half-life ~15-30 minutes (hepatic metabolism). |
| Protein binding | Negligible (<1%); ions are free in plasma (no significant protein binding). |
| Volume of Distribution | 0.4 L/kg; distributes mainly in extracellular fluid (ECF). |
| Bioavailability | 100% (intravenous); not absorbed orally. |
| Onset of Action | Immediate upon intravenous infusion; correction of hypovolemia occurs within minutes. |
| Duration of Action | Short; effects last ~1-2 hours post-infusion due to rapid renal excretion and redistribution. |
| Molecular Weight | N/A (mixture of ions: Na=23, Cl=35.5, Ca=40.1, Mg=24.3, etc.) |
Intravenous infusion, rate adjusted based on clinical status and electrolyte needs; typical adult dose is 500-1000 mL over 1-2 hours.
| Dosage form | SOLUTION |
| Renal impairment | Contraindicated in oliguric or anuric renal failure; in GFR <30 mL/min, avoid use or monitor electrolytes closely; no specific GFR-based dose adjustment. |
| Liver impairment | No specific Child-Pugh based adjustments; use with caution in hepatic impairment due to risk of fluid overload. |
| Pediatric use | Weight-based dosing: 5-10 mL/kg intravenous infusion over 1-2 hours, not to exceed 30 mL/kg/day. |
| Geriatric use | 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 mL over 2-3 hours. |
| 1st trimester | Physiosol pH 7.4 is a balanced electrolyte solution; no known teratogenic effects. Use only if clearly needed. |
| 2nd trimester | Generally safe; monitor for electrolyte imbalances and fluid overload. |
| 3rd trimester | Safe when used appropriately; caution near term due to possible fluid shifts. |
Clinical note
Comprehensive clinical and safety monograph for PHYSIOSOL PH 7.4 IN PLASTIC CONTAINER (PHYSIOSOL PH 7.4 IN PLASTIC CONTAINER).
| Placental transfer | Components (sodium, chloride, calcium, magnesium, etc.) cross placenta via normal physiological mechanisms; no specific studies for this product. |
| Breastfeeding | Physiosol pH 7.4 components are normal plasma constituents; no anticipated harm to infant during breastfeeding. Administer as needed. |
| Lactation Rating | L1 |
| Teratogenic Risk | Physiosol pH 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. |
| Fetal Monitoring | Monitor maternal serum electrolytes, fluid balance, and renal function during prolonged or high-volume administration. In pregnancy, monitor for signs of fluid overload or electrolyte disturbances due to increased plasma volume. |
| Fertility Effects | No known adverse effects on fertility. The solution contains standard electrolytes and water, which are not expected to impair reproductive function. |
■ FDA Black Box Warning
None.
| Serious Effects |
Hypersensitivity to any componentSevere hypercalcemiaSevere hypermagnesemiaSevere hypernatremia
| Precautions | Use with caution in patients with severe renal impairment, heart failure, or conditions associated with sodium retention, Monitor serum electrolytes, fluid balance, and acid-base status during prolonged administration, Risk of volume overload in patients with compromised cardiac or renal function, Contains aluminum; may be toxic with prolonged use in patients with renal impairment |
| Food/Dietary | No food interactions are relevant as Physiosol pH 7.4 is not ingested. It is used exclusively for topical irrigation during medical procedures. |
| Clinical Pearls | Physiosol pH 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 pH, 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. |
| Patient Advice | 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. |
