Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, leading to analgesic, anti-inflammatory, and antipyretic effects. Pseudoephedrine is a sympathomimetic amine that directly acts on alpha-adrenergic receptors in the nasal mucosa, causing vasoconstriction and reducing nasal congestion.
Nepafenac is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX) enzymes, primarily COX-2, reducing prostaglandin synthesis and thereby suppressing ocular inflammation and pain.

1-2 tablets (each containing ibuprofen 200 mg and pseudoephedrine 30 mg) orally every 4-6 hours as needed; maximum 6 tablets in 24 hours. Do not exceed 1200 mg ibuprofen and 180 mg pseudoephedrine per day.
One drop of 0.1% ophthalmic suspension instilled into the affected eye(s) three times daily.
Ibuprofen: 2-4 hours (terminal; rapid elimination, no accumulation with intermittent use). Pseudoephedrine: 4-8 hours (terminal; prolonged in alkaline urine, up to 16 hours at p H 8).
The terminal elimination half-life of nepafenac is approximately 12.5 hours in plasma, while its active metabolite amfenac has a half-life of about 24 hours. This supports twice-daily dosing.
Ibuprofen is primarily metabolized by CYP2C9 and CYP2C8. Pseudoephedrine is partially metabolized in the liver by N-demethylation.
Nepafenac is metabolized via ocular tissues to amfenac, the active metabolite. Systemic metabolism primarily involves hepatic conjugation and oxidation.
Renal excretion of unchanged drug and metabolites: ibuprofen ~45-60% (primarily as conjugated metabolites, <10% unchanged), pseudoephedrine ~70-90% unchanged. Biliary/fecal elimination accounts for <10% for both components.
Nepafenac is extensively metabolized, primarily via hydrolysis to amfenac. Renal excretion accounts for approximately 85% of the administered dose, with about 13% excreted as unchanged nepafenac and amfenac in urine. Fecal elimination is minimal.
Ibuprofen: ~99% primarily to albumin. Pseudoephedrine: negligible (<10% bound to plasma proteins).
Nepafenac is approximately 98% bound to plasma proteins, primarily albumin.
Ibuprofen: 0.1-0.2 L/kg (low Vd, indicating limited tissue distribution). Pseudoephedrine: 2.5-3.5 L/kg (high Vd, extensive tissue distribution including CNS).
The apparent volume of distribution (Vd/F) is approximately 0.6 L/kg (range 0.5-0.7 L/kg), suggesting distribution into total body water and some tissue binding.
Oral: ibuprofen ~80-100% (rapidly absorbed, no significant first-pass). Pseudoephedrine ~100% (well absorbed, minimal first-pass metabolism).
Ophthalmic: Systemic bioavailability after topical ocular administration is very low (approximately 0.1-1% of the dose), but sufficient for local ocular effects. Oral bioavailability is not clinically relevant as drug is only used ophthalmically.
GFR 30-89 m L/min: Use lowest effective dose for shortest duration; monitor renal function. GFR <30 m L/min or dialysis: Contraindicated.
No dose adjustment required in renal impairment; systemic exposure is minimal due to topical administration.
Child-Pugh Class A: No adjustment; use with caution. Child-Pugh Class B or C: Avoid use.
No dose adjustment required in hepatic impairment; systemic exposure is minimal.
Children <12 years: Do not use. Children ≥12 years: Same as adult dosing; 1-2 tablets every 4-6 hours as needed; maximum 6 tablets in 24 hours.
Safety and efficacy in pediatric patients have not been established; use is not recommended.
Use lowest effective dose for shortest duration; avoid chronic use. Reduce initial dose to 1 tablet every 6-8 hours due to increased risk of renal impairment, GI bleeding, and cardiovascular events.
No specific dose adjustment; dosing is identical to standard adult dosing.
Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at greater risk. NSAIDs are contraindicated for the treatment of perioperative pain in the setting of coronary artery bypass graft (CABG) surgery.
No FDA black box warning.
Cardiovascular thrombotic events, gastrointestinal bleeding/ulceration/perforation, hypertension, renal toxicity, serious skin reactions, anaphylactoid reactions, exacerbation of asthma, and drug interactions including with ACE inhibitors, diuretics, and lithium.
Increased bleeding time due to antiplatelet effect,Delayed healing or corneal adverse events including keratitis and corneal perforation,Cross-sensitivity with aspirin or other NSAIDs,Use with caution in patients with bleeding diatheses or concurrent anticoagulants
Hypersensitivity to ibuprofen, aspirin, or other NSAIDs; history of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs; patients with severe hypertension or coronary artery disease; patients taking monoamine oxidase inhibitors (MAOIs) or within 14 days of stopping MAOIs; concurrent use of other sympathomimetics; in the setting of CABG surgery.
Hypersensitivity to nepafenac or any component of the formulation,History of asthma, urticaria, or allergic-type reactions to aspirin or other NSAIDs
Take with food or milk to reduce gastrointestinal irritation. Avoid alcohol consumption as it increases the risk of NSAID-related gastric ulcers and bleeding. High-sodium foods may exacerbate hypertension in patients sensitive to the pressor effects of pseudoephedrine.
No clinically significant food interactions have been identified with ophthalmic nevanac. Systemic absorption is minimal, so dietary restrictions are not required.
First trimester: Ibuprofen (NSAID) is associated with increased risk of miscarriage and congenital malformations, particularly cardiac defects, with odds ratio 1.86 (95% CI 1.32-2.62) for any malformation and 1.86 (95% CI 1.32-2.62) for cardiac malformations. Second trimester: Risk of oligohydramnios and premature closure of ductus arteriosus after 20 weeks. Third trimester: Avoid after 30 weeks due to risk of premature ductus arteriosus closure and oligohydramnios; after 32 weeks, increased risk of necrotizing enterocolitis, intracranial hemorrhage, and renal impairment in neonate (renal agenesis/dysgenesis). Pseudoephedrine: First trimester – possible increased risk of gastroschisis (odds ratio 1.8, 95% CI 1.0-3.2) and small intestinal atresia. Second and third trimesters: potential uteroplacental vasoconstriction leading to fetal hypoxia; risk of prematurity and low birth weight.
Nepafenac is an NSAID. First trimester: limited human data, but NSAIDs as a class are associated with increased risk of spontaneous abortion and cardiac defects. Second trimester: generally considered lower risk for teratogenicity, but avoid if possible. Third trimester: increased risk of premature closure of the ductus arteriosus, oligohydramnios, and fetal renal impairment. Ophthalmic use results in minimal systemic absorption, but theoretical risks remain. Use only if clearly needed.
Ibuprofen: M/P ratio 0.005–0.006; low transfer into breast milk; AAP compatible; theoretical risk of platelet dysfunction in neonate. Pseudoephedrine: M/P ratio 2.6–3.5 (concentrated in milk); estimated infant dose 4.3% of maternal weight-adjusted dose; may cause irritability and sleep disturbances in infant; may reduce milk production by up to 24%. Caution advised; avoid in lactation if possible.
No data on nepafenac in breast milk. Ophthalmic administration yields negligible systemic concentrations. M/P ratio not determined. Considered likely compatible with breastfeeding due to minimal absorption, but caution advised.
Ibuprofen: No dose adjustment required; however, use lowest effective dose and shortest duration; avoid after 30 weeks gestation. Pseudoephedrine: No specific dose adjustment recommended based on pharmacokinetic changes, but use with caution due to vasoconstrictive effects; reduced efficacy may be observed due to increased plasma volume and renal clearance.
No dose adjustments are typically required due to ophthalmic administration; systemic exposure is negligible. However, avoid use in third trimester unless potential benefit outweighs risk. No pharmacokinetic changes in pregnancy necessitate dose adjustment for topical ophthalmic formulation.
Advil Cold and Sinus is a fixed-dose combination of ibuprofen (NSAID) and pseudoephedrine (decongestant). Ibuprofen inhibits COX-1/2, reducing prostaglandin synthesis, while pseudoephedrine is an α-adrenergic agonist causing vasoconstriction in nasal mucosa. Use cautiously in patients with hypertension, cardiovascular disease, or renal impairment due to pseudoephedrine's pressor effects and ibuprofen's potential to reduce renal blood flow and antagonize antihypertensives. Avoid in patients with severe coronary artery disease, uncontrolled hypertension, or concurrent MAOI use. Max duration: 3 days for sinus symptoms, 5 days for pain. Monitor for NSAID-induced GI bleeding, especially in elderly or those on anticoagulants/aspirin.
Nevanac (nepafenac) is a nonsteroidal anti-inflammatory drug (NSAID) ophthalmic suspension indicated for pain and inflammation associated with cataract surgery. Its prodrug formulation enhances corneal penetration, with active metabolite amfenac inhibiting COX-1 and COX-2. Administer one drop three times daily starting 1 day prior to surgery, continuing on day of surgery and for 2 weeks postoperatively. Avoid concurrent use of other NSAIDs or corticosteroids to mitigate risk of corneal adverse events. Monitor for signs of corneal epithelial breakdown, especially in patients with compromised corneal innervation (e.g., diabetes, prior ocular surgery).
