Ketorolac tromethamine, a nonsteroidal anti-inflammatory drug (NSAID), inhibits prostaglandin synthesis by blocking cyclooxygenase (COX-1 and COX-2) enzymes. This reduces ocular inflammation and pain.
Sodium bicarbonate dissociates to provide bicarbonate ion, which neutralizes hydrogen ions and increases blood p H. It also acts as a buffer in acid-base disorders.
Reduction of ocular pain and inflammation following cataract surgery,Treatment of ocular itching associated with seasonal allergic conjunctivitis
FDA-approved: Treatment of metabolic acidosis (e.g., renal tubular acidosis, diabetic ketoacidosis adjunct, cardiac arrest-associated acidosis),Off-label: Alkalinization of urine to prevent uric acid nephropathy, treatment of certain drug intoxications (e.g., tricyclic antidepressants, salicylates), management of acidosis in cardiopulmonary bypass or hemodialysis
1 drop in the affected eye 4 times daily.
IV: 1 m Eq/kg/dose initial, then 0.5 m Eq/kg/dose every 10 minutes as needed; max 8 m Eq/kg/day. Also given as IV infusion: 50-150 m Eq in 1 L D5W at 1-1.5 L/hour for metabolic acidosis. Oral: 325-2000 mg 1-4 times daily.
Terminal elimination half-life is approximately 46 minutes in the aqueous humor following ocular administration in humans.
5–7 minutes (bicarbonate in plasma); short due to rapid equilibration with CO2 and renal excretion. Continuous infusion required for sustained effect.
Primarily hepatic via conjugation with glucuronic acid; minor role of cytochrome P450 enzymes. Approximately 50% is excreted as parent drug and metabolites in urine.
Sodium bicarbonate is not metabolized; it dissociates into sodium and bicarbonate ions in body fluids. Bicarbonate is primarily eliminated via the kidneys (renal excretion) and lungs (conversion to CO2).
Primarily renal excretion of metabolites; less than 1% excreted unchanged. Biliary/fecal elimination accounts for <10%.
Renal: >99% as bicarbonate and carbon dioxide. Minimal biliary/fecal elimination.
>99% bound to plasma proteins, primarily albumin.
<1% (essentially negligible; not significantly protein bound).
Intravenous administration in animals suggests Vd ~0.15 L/kg, indicating limited distribution; clinically, it distributes into aqueous humor after topical dosing.
0.4–0.5 L/kg (distributes into extracellular fluid; minimal intracellular penetration).
Ocular bioavailability is dependent on formulation; systemic bioavailability after topical ocular administration is extremely low (<1%).
Intravenous: 100%; Oral: ~100% (completely absorbed; but effect on systemic p H is limited due to rapid renal elimination and buffering).
No adjustment required. Drug is minimally systemically absorbed.
No specific dose adjustment for GFR; however, sodium bicarbonate can cause fluid overload and metabolic alkalosis in renal impairment. Use with caution in patients with GFR <30 m L/min; monitor serum sodium and bicarbonate levels closely.
No adjustment required. Drug is minimally systemically absorbed.
No specific dose adjustment based on Child-Pugh score. Use with caution in severe hepatic impairment due to risk of fluid overload and alkalosis.
Safety and efficacy in pediatric patients have not been established.
IV: 1 m Eq/kg/dose slow IV push (not to exceed 10 m Eq/min) for acute acidosis; may repeat in 10-15 minutes. Oral: 1-5 m Eq/kg/day in divided doses; typical starting dose 1-2 m Eq/kg/day.
No specific dosage adjustment is recommended; use same dose as younger adults.
Use lowest effective dose; monitor for fluid overload, electrolyte imbalances, and metabolic alkalosis. Initiate at 25-50% of adult dose and titrate slowly due to decreased renal function and comorbidities.
No black box warning for ophthalmic use; however, systemic NSAIDs carry risk of serious cardiovascular and gastrointestinal events. Ophthalmic use rarely associated with corneal adverse events.
No FDA boxed warning exists for sodium bicarbonate.
Use with caution in patients with bleeding disorders or those on anticoagulants; may prolong bleeding time. Avoid in patients with known hypersensitivities to NSAIDs or aspirin. Can cause corneal keratopathy; discontinue if corneal epithelial breakdown occurs.
Risk of hypernatremia, hyperosmolality, and fluid overload, especially in patients with renal impairment or heart failure.,Paradoxical intracellular acidosis may occur due to rapid CO2 generation.,Extravasation can cause tissue necrosis (administer via central line if concentrated solutions).,Avoid excessive doses; monitor serum electrolytes, p H, and calcium levels.
Hypersensitivity to any component of the formulation. Active corneal epithelial defect. Patients with aspirin-sensitive asthma.
Absolute: Metabolic alkalosis, hypocalcemia (may precipitate tetany), concurrent conditions with alkalosis risk (e.g., vomiting, nasogastric suction).,Relative: Renal failure (risk of sodium and bicarbonate overload), congestive heart failure, hypertension, or other sodium-retaining states.
No specific food interactions; systemic absorption is minimal with ophthalmic use. Avoid concurrent use of other NSAID eye drops due to additive irritation.
Avoid high-sodium foods during therapy to prevent fluid overload. No specific food interactions are known.
Acuvail (ketorolac tromethamine ophthalmic solution) is classified as FDA Pregnancy Category C. Systemic exposure after ocular administration is minimal; however, NSAIDs may cause premature closure of the ductus arteriosus and oligohydramnios in the third trimester. Use during the first and second trimesters should be limited to cases where potential benefit outweighs risk; avoid during the third trimester due to risk of fetal harm.
Sodium bicarbonate is not known to be teratogenic in humans. In animal studies, no teratogenic effects were observed at doses equivalent to human therapeutic doses. However, during pregnancy, especially in the first trimester, use only if clearly needed and potential benefit justifies risk to the fetus. Administration during labor may lead to metabolic alkalosis and hypernatremia in the neonate.
Ketorolac is excreted in human milk following systemic administration, but ocular doses produce negligible systemic levels. The M/P ratio is not determined for ophthalmic use. Use with caution in nursing mothers, as the clinical significance is likely low due to minimal systemic absorption.
Sodium bicarbonate is excreted into breast milk in concentrations similar to plasma. The M/P ratio is approximately 1.0. It is considered compatible with breastfeeding; however, excessive doses could potentially cause metabolic alkalosis in the infant. Use caution with high doses or prolonged therapy.
No dosage adjustment is required for ophthalmic use during pregnancy, as systemic exposure is negligible. However, avoid use in third trimester due to risks. Pharmacokinetic changes in pregnancy do not significantly alter ocular delivery.
No specific dose adjustment is required for pregnancy based on pharmacokinetic changes. However, close monitoring of electrolytes and acid-base status is recommended due to altered physiological states (e.g., increased plasma volume, renal function changes). Individualize dosing based on patient's acid-base and electrolyte status.
Acuvail (ketorolac tromethamine ophthalmic solution 0.45%) is a nonsteroidal anti-inflammatory drug (NSAID) for ocular use. It is preserved with sodium chloride and not benzalkonium chloride, reducing corneal epithelial toxicity. Administer 1 drop twice daily for ocular pain and inflammation following cataract surgery. Use caution in patients with bleeding tendencies or those on anticoagulants due to risk of increased ocular bleeding. Monitor for corneal epithelial defects and keratitis, especially with prolonged use.
Sodium bicarbonate in plastic container is used for metabolic acidosis treatment. Avoid rapid administration in neonates due to risk of hypernatremia and intraventricular hemorrhage. Monitor serum sodium, bicarbonate, and p H during infusion. Do not administer with calcium-containing solutions to prevent precipitation. Plastic containers may leach DEHP; use with caution in pediatric patients.

No interactions on record
"Mycophenolic acid, a prodrug of mycophenolate mofetil, undergoes enterohepatic recirculation and is absorbed in the stomach and proximal small intestine. Sodium bicarbonate, by raising gastric pH, can reduce the dissolution and absorption of mycophenolic acid, leading to decreased systemic exposure and potentially reduced immunosuppressive efficacy. This interaction may increase the risk of transplant rejection when used concurrently."
"Sodium bicarbonate, an alkalizing agent, can increase the gastric pH, which may reduce the dissolution and absorption of topically administered clobetasol propionate if swallowed inadvertently. However, this interaction is not clinically significant for topical application, as systemic absorption of clobetasol is minimal. The theoretical decrease in bioavailability is unlikely to affect efficacy or safety."
"Perphenazine, a phenothiazine antipsychotic, can reduce the absorption of sodium bicarbonate by delaying gastric emptying and increasing gastrointestinal transit time. This results in decreased systemic availability of bicarbonate, potentially attenuating its alkalinizing effect and compromising its efficacy in conditions requiring urinary alkalinization or systemic acidosis correction."
