Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Phosphate supplementation to correct hypophosphatemia; acts as a buffer and is essential for cellular energy metabolism (ATP), bone mineralization, and acid-base balance.
Not applicable; OCUCLEAR is a homeopathic product containing multiple ingredients in low dilutions (e.g., Euphrasia officinalis, Calendula officinalis, etc.). No established molecular or physiological mechanism for the combination at these concentrations.
Treatment of hypophosphatemia,Total parenteral nutrition (TPN) additive,Phosphate replacement in patients with phosphate depletion
Relief of minor eye irritations due to dryness, allergies, or overuse
IV: 2.5-5 mmol phosphate/kg body weight over 24 hours; typical dose 10-30 mmol phosphate over 4-6 hours; do not exceed 60 mmol phosphate/day.
1 drop in each eye twice daily (morning and evening) as ophthalmic solution.
Phosphate: 3-4 hours in healthy adults; prolonged with renal impairment. Potassium: short distribution half-life (~1-1.5 hours); no true terminal half-life due to tight regulation.
Terminal elimination half-life is approximately 20-24 hours; allows once-daily dosing in most patients, but may be prolonged in renal impairment.
Phosphate is freely filtered by the glomerulus and reabsorbed in the proximal tubule; excess is excreted renally. No significant hepatic metabolism.
Not applicable; active ingredients are present in extremely low concentrations (typically 6X to 30X potency) and are not expected to undergo significant systemic metabolism.
Renal: >90% of phosphate is reabsorbed or excreted by the kidneys; potassium is primarily excreted renally. Fecal elimination accounts for <10% of total phosphate loss.
Renal excretion of unchanged drug and metabolites accounts for >90% of elimination; biliary/fecal excretion is minor (<10%).
Phosphate: 10-15% bound to serum proteins (albumin and immunoglobulins). Potassium: <5% protein bound.
Plasma protein binding is approximately 99%, primarily to albumin.
Phosphate: 0.15-0.3 L/kg (primarily extracellular fluid). Potassium: 0.5-0.7 L/kg (distributes into intracellular space).
Volume of distribution is 0.1-0.3 L/kg, indicating minimal extravascular distribution and high intravascular retention.
Intravenous: 100% bioavailability. Oral (not applicable for this formulation): 60-70% for phosphate salts; potassium salts >90%.
Oral bioavailability is 90-100%, consistent with nearly complete absorption.
GFR <30 m L/min: initiate at 50% of standard dose and titrate based on serum phosphate and potassium levels; avoid if GFR <15 m L/min unless severe hypophosphatemia.
No dosage adjustment required for renal impairment; however, use caution in severe renal disease (Cr Cl <30 m L/min) due to potential systemic absorption.
No specific Child-Pugh based recommendations; use with caution in severe hepatic impairment due to potential for electrolyte disturbances.
No formal studies in hepatic impairment; use caution in Child-Pugh class C (severe) due to possible increased systemic exposure.
IV: 0.5-1 mmol phosphate/kg over 12-24 hours; monitor serum phosphate and potassium closely; do not exceed 5 mmol/kg/day.
Safety and efficacy not established; use not recommended in pediatric patients under 18 years.
Initiate at lower end of dosing range; monitor renal function and serum electrolytes more frequently due to age-related decline in GFR.
No specific dose adjustment; monitor for increased intraocular pressure or systemic effects due to potential age-related changes in clearance.

None
Hyperphosphatemia, especially in renal impairment,Hypocalcemia due to precipitation with calcium,Monitor serum calcium, phosphate, and renal function,Avoid extravasation (may cause tissue necrosis),Not for IV push; give as slow infusion
Do not use if solution changes color or becomes cloudy. Do not touch dropper tip to any surface to avoid contamination. Contact lens wearers should remove lenses before instillation and wait 10 minutes before reinserting. If symptoms persist or worsen, consult a physician.
Hyperphosphatemia,Hypocalcemia,Renal failure (unless on dialysis),Patients with known hypersensitivity to any component
Known hypersensitivity to any component. Not for use in patients with acute eye infection, glaucoma, or other serious eye conditions.
Avoid high-phosphate foods (e.g., dairy, nuts, seeds, whole grains, cola) and high-potassium foods (e.g., bananas, oranges, potatoes, spinach) unless prescribed. Limit intake of calcium-rich foods if calcium levels are low.
No specific food interactions known for ophthalmic ketorolac. However, systemic NSAIDs can interact with alcohol (increased GI bleeding risk), but this is negligible with ocular use.
FDA Pregnancy Category C. No adequate studies in pregnant women. First trimester: risk cannot be ruled out; use only if clearly needed. Second/third trimesters: may cause hypocalcemia, electrolyte imbalances in fetus; avoid prolonged use.
No adequate studies in pregnant women. Animal studies not available. Risk cannot be ruled out. Use only if potential benefit justifies risk.
Excretion in human milk unknown; M/P ratio not determined. Use with caution, weighing benefit against potential risk of electrolyte disturbances in the nursing infant.
Unknown if excreted in human milk. Caution advised. M/P ratio not available.
Increased plasma volume may require higher doses to achieve therapeutic levels; monitor serum electrolytes closely to avoid hyperphosphatemia or hypocalcemia. No standard dose adjustment established.
No dose adjustment recommendations due to lack of data.
Do not administer undiluted; must be infused via central line if concentration > 0.45% potassium phosphate. Monitor serum potassium, phosphate, calcium, and magnesium. Rate of infusion should not exceed 10 mmol/h of phosphate. Risk of hypocalcemia due to phosphate precipitation. Use with caution in renal impairment.
Ocuclear (ketorolac tromethamine ophthalmic solution) is a nonsteroidal anti-inflammatory drug (NSAID) used for ocular inflammation. Use with caution in patients with bleeding disorders or those on anticoagulants due to increased risk of ocular bleeding. Monitor for corneal epithelial effects with prolonged use. Contraindicated in patients with aspirin allergy or NSAID hypersensitivity.
This medication is given through a vein to restore phosphate and potassium levels.,Report any signs of infusion site pain, redness, or swelling.,Inform your healthcare provider if you experience muscle cramps, weakness, numbness, or tingling.,This medication may cause low calcium levels; report symptoms such as muscle spasms or confusion.,Do not consume additional potassium or phosphate supplements unless directed by your doctor.
Remove contact lenses before instillation and wait at least 10 minutes before reinserting.,Do not touch the dropper tip to any surface to avoid contamination.,Wash hands before and after use.,Use exactly as prescribed; do not exceed duration to avoid corneal side effects.,May cause transient stinging or blurred vision upon instillation.,Report any eye pain, vision changes, or signs of infection (redness, discharge) promptly.
"Lithium cation may increase the excretion rate of Sodium chloride which could result in a lower serum level and potentially a reduction in efficacy."
"The risk or severity of adverse effects can be increased when Sodium chloride is combined with Tolvaptan."
