Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
ROXYBOND is an immediate-release formulation of oxycodone, a full mu-opioid receptor agonist. It binds to mu-opioid receptors in the central nervous system (CNS), inhibiting ascending pain pathways and altering pain perception and emotional response to pain.
Oxaprozin is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), thereby reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.
Management of pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate
Rheumatoid arthritis,Osteoarthritis,Juvenile idiopathic arthritis,Ankylosing spondylitis (off-label),Acute gout (off-label)
Immediate-release oral tablets: 5-15 mg every 4-6 hours as needed for pain. Maximum 60 mg/day. For extended-release: 10-20 mg every 12 hours, adjusted based on prior opioid use.
Oxaprozin is administered orally. The usual adult dose is 1200 mg once daily. For osteoarthritis and rheumatoid arthritis, dosing can range from 600 to 1200 mg once daily. A starting dose of 600 mg once daily may be considered for patients with low body weight or milder disease.
3.5–6 hours; prolonged in renal impairment, hepatic impairment, or elderly patients, requiring dose adjustment.
50-65 hours (mean 57 hours); clinically significant accumulation occurs with multiple dosing, requiring dose adjustment in elderly and renal impairment.
Primarily hepatic via CYP3A4 and to a lesser extent CYP2D6. Oxycodone is metabolized to noroxycodone (via CYP3A4), oxymorphone (via CYP2D6), and other minor metabolites.
Primarily hepatic via cytochrome P450 (CYP) 2C9 and CYP2C8; minor metabolism via glucuronidation. Metabolites are inactive.
Primarily renal (90% as free drug and glucuronide conjugates). Fecal elimination accounts for <10%.
Renal: 85% (60-90% as oxaprozin glucuronide and 5-10% as unchanged oxaprozin); Fecal: <5%; Biliary: negligible.
Approximately 20–30%, primarily to albumin.
>99.5% bound to albumin.
2.6–4.0 L/kg, indicating extensive tissue distribution (e.g., brain, lungs, liver).
0.15-0.25 L/kg; low Vd indicates extensive plasma protein binding and limited tissue distribution.
Oral: 10–20% (extensive first-pass metabolism); intranasal: 30–50%; intravenous: 100%.
Oral: approximately 100% (well absorbed with no significant first-pass metabolism).
For GFR 30-59 m L/min: reduce dose by 25% and increase dosing interval. For GFR <30 m L/min: reduce dose by 50% and administer every 12 hours. Avoid in ESRD.
For patients with creatinine clearance (Cr Cl) of 50-79 m L/min: no dose adjustment is generally required, but monitor for adverse effects. For Cr Cl 30-49 m L/min: reduce dose by 50% or use 600 mg once daily. For Cr Cl <30 m L/min: use is contraindicated. End-stage renal disease (ESRD): avoid use.
Child-Pugh Class A: no adjustment. Child-Pugh Class B: reduce dose by 50% and increase interval. Child-Pugh Class C: avoid use.
Child-Pugh Class A (mild impairment): no dose adjustment needed. Child-Pugh Class B (moderate impairment): reduce dose by 50% or use 600 mg once daily; monitor closely. Child-Pugh Class C (severe impairment): use is contraindicated. No specific studies; caution advised.
Weight-based dosing: 0.1-0.2 mg/kg/dose every 4-6 hours as needed. Maximum single dose: 5 mg for <50 kg, 10 mg for ≥50 kg.
Not approved for pediatric use. Safety and efficacy have not been established in patients under 18 years. Avoid use in children and adolescents unless under expert guidance and with caution.
Start at lowest effective dose (2.5-5 mg every 4-6 hours). Titrate slowly due to increased sensitivity and risk of respiratory depression. Monitor renal function.
Elderly patients (≥65 years) are at increased risk for NSAID-related adverse effects, including GI bleeding, renal impairment, and cardiovascular events. Initiate therapy at the lowest effective dose (e.g., 600 mg once daily) and monitor renal function, blood pressure, and for signs of GI toxicity. Avoid use if possible in patients with high cardiovascular risk or history of GI ulceration.
Addiction, Abuse, and Misuse; Life-Threatening Respiratory Depression; Accidental Ingestion; Neonatal Opioid Withdrawal Syndrome; Risks from Concomitant Use with Benzodiazepines or Other CNS Depressants; and Risk of Medication Errors (due to immediate-release formulation, which requires careful dose conversion from other oxycodone products).
Cardiovascular risk: NSAIDs may increase risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. This risk may increase with duration of use and in patients with cardiovascular risk factors. Gastrointestinal risk: NSAIDs increase risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of stomach or intestines, which can be fatal. These events can occur at any time without warning.
Life-threatening respiratory depression, especially in elderly, cachectic, or debilitated patients and those with pre-existing respiratory conditions.,Risk of opioid-induced hyperalgesia.,Adrenal insufficiency with prolonged use.,Severe hypotension, including orthostatic hypotension, in patients with compromised ability to maintain blood pressure.,Risk of serotonin syndrome with concomitant serotonergic drugs.,Seizures in patients with seizure disorders or taking other seizure threshold-lowering drugs.,Avoid abrupt discontinuation; taper dose to prevent withdrawal syndrome.
Cardiovascular thrombotic events (MI, stroke),Gastrointestinal bleeding, ulceration, perforation,Renal toxicity (elevated creatinine, nephrotoxicity),Hepatic effects (transaminase elevations, rare severe hepatotoxicity),Hypertension exacerbation,Fluid retention and edema,Anaphylactoid reactions,Serious skin reactions (e.g., exfoliative dermatitis, Stevens-Johnson syndrome),Premature closure of ductus arteriosus in pregnancy,Hematologic effects (anemia, bleeding)
Significant respiratory depression,Acute or severe bronchial asthma in an unmonitored setting or without resuscitative equipment,Known or suspected gastrointestinal obstruction, including paralytic ileus,Hypersensitivity to oxycodone or any component of the formulation
Hypersensitivity to oxaprozin or any NSAID,History of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs,In setting of coronary artery bypass graft (CABG) surgery,Advanced renal disease,Pregnancy (third trimester) due to risk of preterm closure of ductus arteriosus and oligohydramnios
Avoid alcohol and any alcohol-containing foods or beverages. Grapefruit and grapefruit juice may increase oxycodone levels; avoid concurrent use.
May be taken with food or milk to minimize gastrointestinal irritation. Avoid alcohol due to increased risk of GI bleeding. No specific food restrictions otherwise.
ROXYBOND (oxycodone) is an opioid agonist. First trimester: Limited human data; animal studies show no teratogenicity at clinically relevant doses. Second and third trimesters: Chronic use may lead to fetal dependence and neonatal opioid withdrawal syndrome (NOWS) after delivery. Avoid during labor due to respiratory depression in the newborn.
First trimester: NSAIDs are not associated with a major teratogenic risk, but avoid due to potential risk of miscarriage. Second trimester: Use only if clearly needed. Third trimester: Avoid after 30 weeks due to premature closure of ductus arteriosus and oligohydramnios. DAYPRO ALTA (oxaprozin) is contraindicated in third trimester.
Small amounts of oxycodone are excreted into breast milk. The milk-to-plasma (M/P) ratio is approximately 3:1. Use with caution, especially in mothers who are ultrarapid metabolizers of CYP2D6, as this increases risk of toxicity in the infant. Monitor infant for drowsiness, poor feeding, and respiratory depression.
Oxaprozin is excreted in human milk; M/P ratio is approximately 0.5. Due to potential adverse effects on infant, caution is advised. Use only if benefit outweighs risk, consider alternative agents.
Pregnancy may increase oxycodone clearance due to expanded blood volume and enhanced hepatic metabolism. Dose adjustments may be needed: consider increasing the frequency or dose based on pain control and tolerance. Avoid high doses near term; use lowest effective dose. Monitor for respiratory depression in both mother and neonate.
In pregnancy, oxaprozin clearance may increase; however, no specific dose adjustment is recommended. Use lowest effective dose for shortest duration during first and second trimesters. Avoid in third trimester.
ROXYBOND (oxycodone hydrochloride) is an immediate-release opioid agonist indicated for acute pain severe enough to require an opioid. Its unique formulation resists crushing and dissolution, but it can still be abused intravenously. Be aware of the risk of respiratory depression, particularly in opioid-naive patients. Use with caution in patients with respiratory disease, or in elderly or debilitated patients. Tolerance and dependence can develop; monitor for signs of misuse. Naloxone is the reversal agent. Not indicated for as-needed use; prescribe the lowest effective dose for the shortest possible duration.
Daypro Alta (oxaprozin) is a nonsteroidal anti-inflammatory drug (NSAID) with a long half-life (~40-50 hours) allowing once-daily dosing. Monitor for GI bleeding, renal impairment, and cardiovascular events. Use with caution in elderly and those with renal insufficiency. Avoid in patients with aspirin-sensitive asthma or NSAID allergy.
