Apo-Ketorolac Ophthalmic Solution (Canada)
Toradol IM (Canada)
Decreases inflammation, pain, and fever through inhibition of prostaglandin synthesis.
Bioavailability is 100% for oral and injection and 60% for intranasal. T max is approximately 44 min for single oral dose (10 mg), 33 to 44 min for IM, 1.1 min for 15 mg IV, 2.9 min for 30 mg IV, and 45 min for intranasal. C max is dose-dependent and is approximately 0.87 mcg/mL for single oral dose (10 mg), 1.14 to 4.55 mcg/mL for IM, 2.47 to 4.65 mcg/mL for IV, and 1.8 mcg/mL for intranasal.
Ketorolac is 99% protein bound. Nevertheless, plasma concentrations as high as 10 mcg/mL will only occupy approximately 5% of the albumin binding sites. A decrease in serum albumin will lead to an increase in free-drug concentrations. Vd is approximately 13 L.
Largely metabolized in the liver via hydroxylation and conjugation. Ketorolac is a racemic mixture of S- and R-enantiomeric forms, with the S-form having analgesic activity.
S-enantiomer is cleared 2 times faster than R-enantiomer. The half-life of S-enantiomer is approximately 2.5 h and the half-life of R-enantiomer is approximately 5 h. 92% of the dose is excreted in the urine (approximately 40% as metabolites and 60% as unchanged drug); 6% is excreted in feces.
30 min for injection.
2 to 3 h.
4 to 6 h for injection.
Special PopulationsRenal Function Impairment
Cl is reduced and half-life is increased to 6 to 19 h. AUC is increased by approximately 100% and Vd increases. Ketorolac is contraindicated in patients with advanced renal impairment and in patients at risk for renal failure because of volume depletion. Adjust dose for patients with moderately elevated serum creatinine.Hepatic Function Impairment
There were no significant differences in patients with liver disease compared with healthy volunteers.Elderly
Half-life is longer in elderly patients. Exposure is increased by 23% in elderly patients after intranasal administration. Adjust dosage for patients 65 y and older.Children
The Vd and Cl were higher in children compared with adults.Race
Pharmacokinetic differences have not been identified.Patients weighing less than 50 kg

- Discard spray 24 h after the first dose.
- Ophthalmic solution
- For ophthalmic use only.
- Have patient tilt head back and instill prescribed number of drops into affected eye(s) as ordered. Have patient close eye(s) for 2 to 3 min and apply light finger pressure to bridge of nose (nasolacrimal duct) for 1 to 2 min after instillation. Do not touch top of dropper bottle to eye, fingers, or other surface.
- If using other topical ophthalmic drugs, separate each medication by at least 5 min. Instill ophthalmic ointment last.
- Advise patient not to administer while wearing contact lenses.
- Keep the bottle tightly capped in between uses.
Store between 59° and 86°F. Store unopened intranasal spray between 36° and 46°F. During use, store intranasal spray between 59° and 86°F. Protect from light.
Drug InteractionsACE inhibitors (eg, captopril), angiotensin II receptor antagonists (eg, losartan)
The risk of renal impairment, particularly in volume-depleted patients, may be increased. In addition, ketorolac may decrease the antihypertensive effect of these agents. Monitor BP and adjust treatment as needed.Alcohol, anticoagulants (eg, warfarin), corticosteroids (oral)
May increase risk of gastric erosion and bleeding. Use with caution. Additional clinical and laboratory monitoring may be warranted.Aminoglycosides (eg, tobramycin)
Coadministration may increase the risk of acute renal insufficiency. If coadministration cannot be avoided, reduce the aminoglycoside dose prior to starting ketorolac. Monitor renal function and aminoglycoside concentrations. Adjust the aminoglycoside dose based on monitored parameters.Antiepileptic agents (eg, carbamazepine, phenytoin)
Sporadic cases of seizures have been reported with concurrent use of ketorolac and antiepileptic agents.Aspirin, NSAIDs (eg, ibuprofen)
Risk of inducing serious NSAID-related adverse effects. Concomitant use is contraindicated.Bisphosphonates (eg, alendronate)
The risk of gastric ulceration may be increased. Use with caution. Closely monitor patients for possible GI adverse reactions, especially gastric ulceration.Clopidogrel, dextrans, heparin
Risk of bleeding complications may be increased. Use with caution.Cyclosporine
Risk of nephrotoxicity may be increased. Closely monitor renal function.Disulfiram, metronidazole
Because ketorolac injection contains alcohol, coadministration may produce an alcohol intolerance reaction. Avoid concurrent use.Food
Oral administration of ketorolac after a high-fat meal may decrease the C max and delay the T max .Furosemide, thiazide diuretics (eg, chlorothiazide)
Ketorolac may reduce the diuretic response by approximately 20%.Lithium
Serum lithium levels may be increased. Closely monitor for signs of lithium toxicity. Adjust the lithium dose as needed.Methotrexate
May increase methotrexate levels increasing the risk of toxicity. Use with caution. Monitor for renal impairment that could predispose to methotrexate toxicity. Monitor methotrexate concentrations and for signs of methotrexate toxicity.Nondepolarizing muscle relaxants (eg, vecuronium)
Although concurrent use has not been formally studied, apnea has been reported during postmarketing experience.Pentoxifylline
The risk of bleeding may be increased. Coadministration is contraindicated.Probenecid
May increase ketorolac plasma levels. Concomitant use is contraindicated.Psychoactive agents (eg, alprazolam, fluoxetine, thiothixene)
Hallucinations have been reported when ketorolac was used in patients taking psychoactive drugs.Quinolones (eg, levofloxacin)
Risk of CNS stimulation and seizures from quinolones may be increased. Also, quinolone plasma concentrations may be increased. Use with caution.Smoking
The risk of GI bleeding may be increased.SSRIs (eg, fluoxetine, paroxetine)
Risk of GI adverse reactions may be increased. Close clinical monitoring is warranted. Use with caution; consider alternative therapy.

Ketorolac inhibits platelet function and is therefore contraindicated in patients with suspected or confirmed cerebrovascular bleeding, hemorrhagic diathesis, incomplete hemostasis, and those at high risk of bleeding. Contraindicated as prophylactic preoperative analgesic.Cardiovascular risk
May cause an increased risk of serious CV thrombotic events, MI, and stroke, which can be fatal. This risk may increase with duration of use. Contraindicated for the treatment of perioperative pain in the setting of CABG surgery.Concomitant use with NSAIDs
Contraindicated in patients currently receiving aspirin or NSAIDs.GI risk
Peptic ulcers, GI bleeding, and/or perforation can occur, which can be fatal. Contraindicated in patients with active peptic ulcer disease, recent GI bleeding or perforation, or history of peptic ulcer disease or GI bleeding.Hypersensitivity
Contraindicated in patients who have previously demonstrated hypersensitivity to ketorolac or allergic manifestations to aspirin or other NSAIDs.Injection
Intrathecal/epidural administration is contraindicated because of alcohol content.Labor, delivery, and breast-feeding
Contraindicated in labor and delivery because it may adversely affect fetal circulation and inhibit uterine contractions. Contraindicated in breast-feeding.Oral, injection, intranasal
Limit therapy to 5 days. Oral therapy is indicated only as continuation therapy to IV/IM, and the combined use is not to exceed 5 days because of the increased risk of serious adverse reactions.Renal risk
Contraindicated in patients with advanced renal impairment or at risk of renal failure caused by volume depletion.Special populations
Dosage should be adjusted for patients 65 y and older, patients weighing less than 50 kg, and patients with moderately elevated serum creatine.
Monitor for signs/symptoms of GI tract ulcerations and bleeding. In patients on long-term treatment, periodically check CBC and chemistry profile. Closely monitor patients receiving therapy that affects hemostasis.
Category C ; Category D if used in the third trimester (starting at 30 wk gestation). Avoid use in late pregnancy because it may cause premature closure of the ductus arteriosus. Contraindicated during labor and delivery.
Excreted in breast milk. Ketorolac intranasal, oral, and injection is contraindicated in breast-feeding women. Use ketorolac ophthalmic with caution.
ChildrenIM/IV, Oral, Intranasal
Safety and efficacy not established in patients younger than 17 y.Ophthalmic
Safety and efficacy not established in patients younger than 3 y (0.4% and 0.5% solution). Safety and efficacy not established in children (0.45% solution).
Increased risk of adverse reactions. A lower dose is recommended in elderly patients 65 y and older.
Hypersensitivity may occur; use drug with caution in aspirin-sensitive individuals because of possible cross-sensitivity. There is also a potential for cross-sensitivity to phenylacetic acid derivatives and other NSAIDs.
Assess function before and during therapy because NSAID metabolites are eliminated renally. Dosage adjustments may be necessary.
Use with caution in patients with hepatic impairment or a history of liver disease.
May occur without known hypersensitivity to ketorolac. Do not give to patients with the aspirin triad.
Patients with asthma may have aspirin-sensitive asthma, which may be associated with severe and sometimes fatal bronchospasm. Do not administer ketorolac to patients with this type of aspirin sensitivity because of possible cross-reactivity.
Fluid retention and edema have been reported with ketorolac. Use with caution in patients with cardiac decompensation, hypertension, or other similar conditions.
Anemia may occur, possibly caused by fluid retention, occult or gross GI blood loss, or an incompletely described effect upon erythropoiesis.
Use cautiously in patients with coagulation disorders. Postoperative hematomas and other signs of wound bleeding have been reported postmarketing in association with the perioperative use of ketorolac IV or IM. Ocularly applied NSAIDs may increase bleeding of ocular tissues in conjunction with ocular surgery.
May lead to liver enzyme elevations. Discontinue if signs/symptoms of liver disease develop, or if systemic manifestations occur (eg, eosinophilia, rash).
New hypertension or worsening of preexisting hypertension, either of which may contribute to increased risk of CV events, may occur.
May mask the usual signs and symptoms of infection.
Use of topical NSAIDs may result in keratitis. Continued use may result in epithelial breakdown, corneal thinning, corneal erosion, corneal ulceration, or corneal perforation. These reactions may be sight-threatening. Patients with complicated ocular surgeries, corneal denervation, corneal epithelial defects, diabetes mellitus, ocular surface diseases, rheumatoid arthritis, or repeat ocular surgeries within a short period of time may be at increased risk of corneal adverse reactions. Topical use of NSAIDs more than 24 h prior to surgery or for use beyond 14 days postsurgery may increase risk of occurrence and severity of corneal adverse reactions.
There have been reports of acute renal failure, nephritis, and nephrotic syndrome in association with ketorolac. Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury.
Use with caution in patients with a history of inflammatory bowel disease (ulcerative colitis, Crohn disease) because their condition may be exacerbated.
Serious and sometimes fatal skin adverse reactions, including exfoliative dermatitis, Stevens-Johnson syndrome, and TEN, have occurred.
All topical NSAIDs and corticosteroids may slow or delay healing. Thus, concomitant use of ketorolac and corticosteroids may increase the risk of healing problems.
Abdominal pain, anaphylactoid reaction, drowsiness, epigastric pain, erosive gastritis, GI bleeding, hyperventilation, lethargy, nausea, peptic ulcers, renal dysfunction, vomiting; acute renal failure, coma, hypertension, respiratory depression (rare).
