Rheumatoid arthritis,Osteoarthritis,Mild to moderate pain,Primary dysmenorrhea,Fever reduction,Gouty arthritis (off-label),Patent ductus arteriosus closure in neonates (off-label)
Fabry disease
200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day without prescription.
150 mg orally twice daily for 4 weeks, followed by 100 mg orally twice daily for 2 weeks, with food.
2-4 hours (terminal elimination half-life); in overdose or hepatic impairment, may be prolonged to >4 hours. Clinically, the short half-life supports dosing every 6-8 hours for acute pain.
Terminal elimination half-life is 12–14 hours in patients with normal renal function; prolonged to 24–36 hours in moderate renal impairment (Cr Cl <60 m L/min), requiring dose adjustment
Primarily hepatic via CYP2C9; also undergoes glucuronidation. Metabolites include hydroxy- and carboxy-ibuprofen, which are inactive.
Metabolized by catabolic pathways into small peptides and amino acids.
Renal excretion of conjugated metabolites (approximately 90% of an administered dose) with less than 1% excreted unchanged. Biliary/fecal elimination accounts for less than 5%.
Approximately 70% renal (unchanged drug), 20% biliary/fecal (conjugates and metabolites), 10% other
Approximately 99% bound to albumin.
97% bound primarily to albumin; minor binding to α1-acid glycoprotein (3%)
0.1-0.3 L/kg. The low Vd indicates limited tissue distribution, primarily confined to plasma and extracellular fluid.
0.45 L/kg (range 0.3–0.6 L/kg); indicates moderate distribution into total body water, with limited tissue binding
Oral: 80-100% (well absorbed). Topical: approximately 5-10% systemically absorbed (varies with formulation and application site).
Oral: 85% (range 75–95%); reduced to 60% when administered with high-fat meal (increased first-pass metabolism)
Cr Cl 30-60 m L/min: reduce dose by 50% and avoid in Cr Cl <30 m L/min.
Cr Cl 30-59 m L/min: 100 mg twice daily for 4 weeks then 75 mg twice daily for 2 weeks; Cr Cl 15-29 m L/min: 75 mg twice daily for 4 weeks then 50 mg twice daily for 2 weeks; Cr Cl <15 m L/min or on dialysis: not recommended.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: contraindicated.
Child-Pugh A or B: no dose adjustment; Child-Pugh C: not recommended.
5-10 mg/kg/dose orally every 6-8 hours; maximum 40 mg/kg/day.
Weight <50 kg: 3 mg/kg (maximum 150 mg) orally twice daily for 4 weeks, then 2 mg/kg (maximum 100 mg) twice daily for 2 weeks; Weight ≥50 kg: same as adult dosing.
Initiate at lowest effective dose (e.g., 200 mg every 8-12 hours); monitor renal function and avoid long-term use.
No specific dose adjustment recommended; monitor renal function and adjust based on Cr Cl.
NSAIDs increase the risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. Risk increases with duration of use. Patients with cardiovascular disease or risk factors may be at greater risk. NSAIDs are contraindicated for treatment of perioperative pain in the setting of coronary artery bypass graft (CABG) surgery.
No FDA boxed warnings reported.
Risk of serious GI adverse events including bleeding, ulceration, and perforation; NSAIDs should be used with caution in patients with history of peptic ulcer disease or GI bleeding. May cause renal toxicity, especially in patients with pre-existing renal impairment. Use with caution in patients with asthma, congestive heart failure, or hypertension.
Hypersensitivity reactions including anaphylaxis,Infusion-associated reactions,Potential for immune complex formation and immune-mediated reactions
History of hypersensitivity to ibuprofen or any other NSAID; active peptic ulcer disease or GI bleeding; severe renal impairment; history of serious cardiovascular event; perioperative pain in CABG surgery; third trimester of pregnancy.
History of life-threatening hypersensitivity to the active substance or any excipients
Alcohol may increase risk of GI bleeding. Food delays absorption but does not significantly affect total exposure; take with food to improve tolerability.
Avoid grapefruit, grapefruit juice, and Seville oranges (contain CYP3A4 inhibitors). High-fat meals do not significantly affect absorption.
First trimester: Association with increased risk of miscarriage and congenital cardiac defects (odds ratio 1.86). Second/third trimester: Premature closure of ductus arteriosus, oligohydramnios, fetal renal impairment; avoid after 30 weeks gestation. Use not recommended during pregnancy.
IBTROZI is contraindicated in pregnancy due to known teratogenicity. First trimester: High risk of major congenital malformations (neural tube defects, craniofacial anomalies). Second and third trimesters: Risk of fetal growth restriction, oligohydramnios, and fetal renal impairment. Effective contraception required during treatment and for 1 month after last dose.
Excreted in breast milk in low concentrations (M/P ratio <0.02). American Academy of Pediatrics considers compatible with breastfeeding. Monitor infant for gastrointestinal distress or rash. Use lowest effective dose for shortest duration.
No human data on presence in breast milk. M/P ratio unknown. Due to potential for serious adverse reactions in nursing infants, breastfeeding is contraindicated during treatment and for 1 month after last dose.
Increased clearance and volume of distribution in pregnancy (especially third trimester) may require dose escalation to maintain efficacy. However, due to fetal risks, avoid use; if necessary, use minimal effective dose for shortest duration.
No dose adjustment recommended as drug is contraindicated in pregnancy. Pharmacokinetic changes in pregnancy (increased volume of distribution, altered clearance) are not applicable due to contraindication.
IBU-TAB (ibuprofen) is a non-selective COX inhibitor; use lowest effective dose for shortest duration to minimize GI and renal risks. Avoid in patients with NSAID-sensitive asthma, severe renal impairment (e GFR <30 m L/min), or perioperative pain in CABG surgery. Concomitant aspirin antagonizes irreversible antiplatelet effect; separate by 2 hours if immediate-release. Monitor for fluid retention and hypertension in cardiac patients.
IBTROZI (ibutropinib) is a selective BTK inhibitor used in relapsed/refractory mantle cell lymphoma. Monitor for atrial fibrillation and bleeding events, especially in patients on anticoagulants. Dose adjustments required for hepatic impairment (Child-Pugh B/C). Concomitant use with strong CYP3A4 inhibitors increases exposure; reduce dose by 50%.
Take with food or milk to reduce stomach upset.,Do not exceed 1200 mg/day without physician approval; higher doses increase risk of bleeding and kidney damage.,Avoid alcohol while taking this medication to reduce risk of stomach bleeding.,Discontinue and seek medical help if you experience signs of allergic reaction (rash, swelling, difficulty breathing) or black/tarry stools.,Inform your doctor about all medications you take, especially blood thinners, aspirin, other NSAIDs, and medications for blood pressure or kidney disease.
Take IBTROZI exactly as prescribed, with or without food. Swallow capsule whole; do not crush or chew.,Avoid grapefruit, grapefruit juice, and Seville oranges as they increase drug levels and risk of side effects.,Report any signs of infection, unusual bruising or bleeding, or irregular heartbeat to your healthcare provider immediately.,Use effective contraception during treatment and for at least 1 month after the last dose, as IBTROZI can cause fetal harm.,Do not breastfeed while taking IBTROZI and for at least 2 weeks after the last dose.
