Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Immunosuppressant; inhibits T-cell activation by binding to cyclophilin and inhibiting calcineurin, thereby blocking IL-2 transcription.
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.

Reduction of ocular pain and inflammation following cataract surgery,Treatment of ocular itching associated with seasonal allergic conjunctivitis
Adults: 10 mg orally once daily.
1 drop in the affected eye 4 times daily.
Terminal elimination half-life is 8-12 hours; prolonged in renal impairment (up to 20-30 hours in anuria).
Terminal elimination half-life is approximately 46 minutes in the aqueous humor following ocular administration in humans.
Hepatic via CYP3A4 enzyme system; major metabolites include AM1, AM9, and AM4N.
Primarily hepatic via conjugation with glucuronic acid; minor role of cytochrome P450 enzymes. Approximately 50% is excreted as parent drug and metabolites in urine.
Renal: 70-80% unchanged; biliary/fecal: 10-15% as metabolites.
Primarily renal excretion of metabolites; less than 1% excreted unchanged. Biliary/fecal elimination accounts for <10%.
20-30% primarily to albumin.
>99% bound to plasma proteins, primarily albumin.
0.25-0.4 L/kg; indicates distribution primarily in extracellular fluid.
Intravenous administration in animals suggests Vd ~0.15 L/kg, indicating limited distribution; clinically, it distributes into aqueous humor after topical dosing.
Intramuscular: approximately 90%; oral: not absorbed (0% due to degradation in GI tract).
Ocular bioavailability is dependent on formulation; systemic bioavailability after topical ocular administration is extremely low (<1%).
GFR 30-89 m L/min: no adjustment; GFR 15-29 m L/min: 5 mg once daily; GFR <15 m L/min or dialysis: 2.5 mg once daily.
No adjustment required. Drug is minimally systemically absorbed.
Child-Pugh A: no adjustment; Child-Pugh B: 5 mg once daily; Child-Pugh C: not recommended.
No adjustment required. Drug is minimally systemically absorbed.
Not established for children <18 years.
Safety and efficacy in pediatric patients have not been established.
No specific dose adjustment; monitor for hypotension and renal function.
No specific dosage adjustment is recommended; use same dose as younger adults.
Increased risk of lymphomas and other malignancies, particularly of the skin. Increased susceptibility to infections. Cyclosporine can cause nephrotoxicity and hepatotoxicity.
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.
Nephrotoxicity, hepatotoxicity, hypertension, hyperkalemia, neurotoxicity, increased risk of infections and malignancies, anaphylaxis (IV formulation).
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.
Hypersensitivity to cyclosporine or any component of the formulation, abnormal renal function, uncontrolled hypertension, malignancies, concurrent use with PUVA or UVB therapy in psoriasis.
Hypersensitivity to any component of the formulation. Active corneal epithelial defect. Patients with aspirin-sensitive asthma.
No significant food interactions. Avoid alcohol while taking this medication.
No specific food interactions; systemic absorption is minimal with ophthalmic use. Avoid concurrent use of other NSAID eye drops due to additive irritation.
First trimester: Limited human data; animal studies show adverse effects at high doses. Avoid unless benefit outweighs risk. Second/third trimester: No documented teratogenicity; monitor for fetal growth restriction and oligohydramnios.
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.
Not recommended during breastfeeding. M/P ratio unknown; potential infant exposure via milk.
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.
No standard dose adjustment; increased clearance in pregnancy may require higher doses; therapeutic drug monitoring advised.
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.
AKTOB is a beta-lactam antibiotic; monitor for hypersensitivity reactions, especially in patients with penicillin allergy. Adjust dose in renal impairment (Cr Cl <30 m L/min). Administer by slow IV infusion over 3-5 minutes or as directed. Observe for signs of Clostridioides difficile infection.
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.

Common clinical questions about AKTOB vs ACUVAIL, answered by our medical review team.
AKTOB is a Aminoglycoside Antibiotic (Ophthalmic) that works by Immunosuppressant; inhibits T-cell activation by binding to cyclophilin and inhibiting calcineurin, thereby blocking IL-2 transcription.. ACUVAIL is a NSAID Ophthalmic that works by 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.. They differ in pharmacokinetic profiles, FDA-approved indications, and side effect profiles.
Potency comparisons between AKTOB and ACUVAIL depend on the specific clinical indication. These are agents from distinct pharmacological classes and are not directly interchangeable by dose. A physician or clinical pharmacist should guide any therapeutic switching decisions.
The standard adult dose of AKTOB is: Adults: 10 mg orally once daily.. The standard adult dose of ACUVAIL is: 1 drop in the affected eye 4 times daily.. Dosing should always be individualized based on indication, renal and hepatic function, age, and other patient factors.
No direct drug-drug interaction has been formally documented between AKTOB and ACUVAIL in current clinical databases. However, individual patient risk factors including other medications, organ function, and comorbidities should always be evaluated by a qualified healthcare provider.
The maternal-fetal safety profiles differ. AKTOB is classified as Category C. First trimester: Limited human data; animal studies show adverse effects at high doses. Avoid unless benefit outweighs risk. Second/third trimester: No documented teratogenicity; m. ACUVAIL is classified as Category C. Acuvail (ketorolac tromethamine ophthalmic solution) is classified as FDA Pregnancy Category C. Systemic exposure after ocular administration is minimal; however, NSAIDs may cause . Always consult a maternal-fetal medicine specialist before taking either drug during pregnancy or lactation.
