Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Hydrocodone is a semisynthetic opioid agonist with selectivity for mu-opioid receptors, producing analgesia and sedation. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, thereby providing anti-inflammatory, analgesic, and antipyretic effects.
Selective COX-2 inhibitor; inhibits prostaglandin synthesis, reducing ocular inflammation and pain.
Short-term (up to 10 days) management of acute pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate
FDA: Treatment of postoperative inflammation in patients who have undergone cataract surgery,Off-label: Relief of ocular pain, photophobia, and inflammation associated with corneal abrasion or refractive surgery
One tablet (hydrocodone bitartrate 5 mg/ibuprofen 200 mg) orally every 4 to 6 hours as needed for pain; maximum 5 tablets per day.
1 drop in the affected eye(s) four times daily
Hydrocodone: 3.8-4.5 hours (immediate release); Ibuprofen: 1.8-2.5 hours (racemic, S-enantiomer slightly shorter). Clinical context: dosing every 4-6 hours due to hydrocodone half-life.
The terminal elimination half-life is approximately 1.8 hours (range 1.2–2.5 hours) following topical ocular administration. This short half-life is consistent with rapid clearance from the systemic circulation.
Hydrocodone is primarily metabolized by CYP3A4 and CYP2D6 enzymes to hydromorphone (active) and norhydrocodone (inactive). Ibuprofen is metabolized by CYP2C9 to inactive metabolites (hydroxyibuprofen and carboxyibuprofen).
Primarily hepatic via CYP2C9; undergoes glucuronidation and oxidation to inactive metabolites.
Hydrocodone: primarily renal (60-70% as metabolites, <12% unchanged); Ibuprofen: primarily renal (90% as metabolites and conjugates, <1% unchanged), minor biliary/fecal.
Renal excretion of metabolites and unchanged drug accounts for approximately 26% of the dose. Fecal excretion accounts for approximately 74% of the dose, primarily as metabolites.
Hydrocodone: ~19% bound to plasma proteins; Ibuprofen: >99% bound to albumin.
Ketorolac is highly protein bound, approximately 99% bound to plasma proteins, primarily albumin.
Hydrocodone: 3.3-4.7 L/kg; Ibuprofen: 0.1-0.2 L/kg. High Vd for hydrocodone indicates extensive tissue distribution; low Vd for ibuprofen indicates plasma and interstitial fluid confinement.
The volume of distribution is approximately 0.12 L/kg, indicating distribution primarily into extracellular fluid with limited tissue penetration.
Hydrocodone: mean absolute bioavailability ~70-80% (oral); Ibuprofen: ~80-100% (oral, rapid absorption).
Ophthalmic bioavailability is approximately 2% of the administered dose due to extensive nasolacrimal drainage and systemic absorption. Oral bioavailability of ketorolac is approximately 80-100%, but this route is not used for ophthalmic formulations.
GFR 30-60 m L/min: Use with caution, consider reducing dose or increasing interval. GFR <30 m L/min: Not recommended due to accumulation of ibuprofen and hydrocodone metabolites.
No dosage adjustment required for renal impairment
Child-Pugh Class B: Start with lowest possible dose, monitor closely. Child-Pugh Class C: Contraindicated due to risk of toxicity.
No dosage adjustment required for hepatic impairment but use with caution in severe hepatic disease due to potential for increased systemic exposure
Not recommended for use in pediatric patients; safety and efficacy not established.
Safety and efficacy in pediatric patients below 2 years of age have not been established; for children 2 years and older, same as adult dosing
Initiate with lowest effective dose (e.g., half tablet) and monitor for CNS and respiratory depression; reduce maximum daily dose to 4 tablets due to increased sensitivity and renal impairment.
No specific dose adjustment recommended; use with caution due to increased incidence of age-related ocular conditions
Risk of addiction, abuse, and misuse; life-threatening respiratory depression; accidental ingestion (especially in children) can be fatal; neonatal opioid withdrawal syndrome with prolonged use during pregnancy; risks from concomitant use with benzodiazepines or other CNS depressants; hepatotoxicity from ibuprofen (NSAIDs cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation, which can be fatal).
None
Addiction, abuse, and misuse; life-threatening respiratory depression; accidental ingestion; neonatal opioid withdrawal syndrome; risks from concomitant use with CNS depressants; severe hypotension; adrenal insufficiency; hepatotoxicity; gastrointestinal bleeding, ulceration, and perforation; cardiovascular thrombotic events; hypertension; renal toxicity; anaphylactoid reactions; serious skin reactions; use in pregnancy; use in breastfeeding; use in hepatic impairment; use in renal impairment; use in elderly; use in patients with bleeding disorders.
Increased risk of bleeding and bleeding-related adverse events due to platelet inhibition,May prolong bleeding time,Cross-sensitivity with aspirin and other NSAIDs,Caution in patients with prior history of corneal epithelial defects or ocular surgery,Not for intraocular injection
Significant respiratory depression; acute or severe bronchial asthma in an unmonitored setting or without resuscitative equipment; known or suspected gastrointestinal obstruction; hypersensitivity to hydrocodone, ibuprofen, or any component; history of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs; perioperative pain relief in the setting of coronary artery bypass graft (CABG) surgery; use within 14 days of monoamine oxidase inhibitor (MAOI) therapy.
Hypersensitivity to ketorolac tromethamine or any component of the formulation,Patients with active peptic ulcer disease, recent GI bleeding, or perforation,Patients with advanced renal disease or at risk for renal failure,Patients with known history of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs
Grapefruit and grapefruit juice may increase hydrocodone levels and risk of adverse effects; avoid concurrent use. Alcohol potentiates CNS depression and increases GI bleeding risk; avoid altogether. High-fat meals may delay absorption of hydrocodone, but clinical impact is minimal; take consistently with or without food.
No known food interactions for ophthalmic ketorolac. However, maintain good hydration and nutrition to support corneal healing.
Pregnancy Category C: No adequate studies in pregnant women. Ibuprofen (NSAID) is associated with increased risk of premature closure of ductus arteriosus and oligohydramnios in third trimester; avoid after 30 weeks gestation. Hydrocodone may cause respiratory depression in neonate if used near term; chronic use may lead to neonatal opioid withdrawal syndrome. First trimester: limited data, but NSAIDs may increase risk of miscarriage; hydrocodone not associated with major malformations. Second trimester: generally considered safer, but risks remain. Third trimester: avoid NSAIDs; hydrocodone use only if benefit outweighs risk.
Ketorolac tromethamine, the active ingredient in ACULAR LS, is a nonsteroidal anti-inflammatory drug (NSAID). In animal reproduction studies, administration of ketorolac during organogenesis resulted in increased embryofetal mortality, delayed ossification, and increased incidence of skeletal abnormalities at doses less than the maximum recommended human ophthalmic dose. However, systemic exposure following ocular administration is very low. NSAIDs are generally avoided during pregnancy, especially in the third trimester, due to the risk of premature closure of the ductus arteriosus and oligohydramnios. The risk is considered low for ophthalmic use but should be used only if clearly needed.
Limited data; both drugs excreted into breast milk. Ibuprofen M/P ratio ~0.01, considered compatible. Hydrocodone M/P ratio ~2.0; low levels in milk but risk of infant sedation and respiratory depression. Use caution; monitor infant for drowsiness, difficulty breastfeeding. American Academy of Pediatrics considers hydrocodone as 'usually compatible' but avoid when possible. Alternatives preferred.
It is not known whether ketorolac is excreted in human milk after ophthalmic administration. Systemic levels are low, and following oral administration, ketorolac is excreted in breast milk at low concentrations (M/P ratio approximately 0.37). Due to the potential for adverse effects on the nursing infant, caution should be exercised. The low systemic absorption likely poses minimal risk.
No specific pharmacokinetic studies; however, pregnancy increases clearance and volume of distribution for both drugs. Ibuprofen: dose adjustments not typically recommended, but due to renal effects and fetal risks, use lowest effective dose for shortest duration. Hydrocodone: increased clearance may require higher doses to achieve analgesic effect; consider patient-specific titration. However, due to neonatal risks, minimize use and duration.
No dosing adjustments are necessary for ophthalmic use during pregnancy due to negligible systemic absorption. Standard dosing (1 drop in the affected eye(s) four times daily) is recommended. Systemic NSAIDs may require dose adjustment due to increased volume of distribution and renal changes, but this does not apply to topical ocular ketorolac.
Hydrocodone/ibuprofen combines an opioid agonist with an NSAID. Be aware of additive risks: respiratory depression, sedation, GI bleeding, renal impairment, and cardiovascular thrombotic events. Avoid in patients with severe asthma, GI obstruction, or after recent bariatric surgery. Use lowest effective dose for shortest duration. Monitor for serotonin syndrome if used with other serotonergic drugs. Abrupt discontinuation after prolonged use may cause withdrawal.
ACULAR LS (ketorolac tromethamine ophthalmic solution 0.4%) is a nonsteroidal anti-inflammatory drug (NSAID) indicated for the reduction of ocular pain and photophobia following corneal refractive surgery. Use with caution in patients with known bleeding tendencies or those on anticoagulants due to increased risk of ocular bleeding. Avoid concurrent use with other NSAIDs or steroids to minimize corneal adverse effects. Monitor for corneal epithelial breakdown or delayed healing.

"Concomitant use of Ibuprofen (a nonsteroidal anti-inflammatory drug, NSAID) and Methylprednisolone (a systemic corticosteroid) synergistically increases the risk of gastrointestinal (GI) ulceration, bleeding, and perforation due to additive inhibition of prostaglandin synthesis and mucosal protection. Additionally, Ibuprofen may potentiate the immunosuppressive effects of Methylprednisolone, elevating infection risk. This interaction can lead to serious clinical outcomes, including acute GI hemorrhage, perforation, and impaired wound healing."
"The combination of olopatadine, an antihistamine with sedative properties, and ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID), may result in additive central nervous system (CNS) depression, leading to increased sedation, dizziness, and impaired psychomotor function. Ibuprofen can inhibit the metabolism of olopatadine via competition for hepatic CYP450 enzymes, potentially elevating olopatadine plasma concentrations and prolonging its systemic effects. Clinically, patients may experience exacerbated drowsiness, reduced alertness, and increased risk of falls or accidents, especially in the elderly or those with compromised hepatic function."
"Ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID), can decrease the metabolism of pioglitazone, a thiazolidinedione antidiabetic agent, by inhibiting cytochrome P450 2C8 (CYP2C8) enzyme activity. This inhibition elevates plasma concentrations of pioglitazone, potentially enhancing its hypoglycemic effects and increasing the risk of adverse reactions such as edema, weight gain, and heart failure exacerbation. Clinically, concomitant use may lead to improved glycemic control but also raises concerns for dose-dependent toxicities, necessitating careful monitoring and possible dose adjustment of pioglitazone."
