Partial agonist at mu-opioid receptors; also a weak antagonist at kappa-opioid receptors. Provides analgesic effects with reduced respiratory depression compared to full agonists.
ibuprofen: non-selective COX-1/COX-2 inhibitor reducing prostaglandin synthesis; phenylephrine: alpha-1 adrenergic receptor agonist causing vasoconstriction
Management of moderate to severe chronic pain,Off-label: Treatment of opioid use disorder (as a maintenance therapy similar to buprenorphine)
temporary relief of nasal congestion,sinus pressure,headache,fever,minor aches and pains associated with common cold or flu
Adults: 200 mg orally twice daily with meals.
1 tablet (ibuprofen 200 mg / phenylephrine 10 mg) orally every 4 hours while symptoms persist, not to exceed 6 tablets in 24 hours.
Terminal elimination half-life is approximately 12-15 hours in patients with normal renal function, allowing for twice-daily dosing.
Ibuprofen: 2-4 hours (short half-life requires frequent dosing). Pseudoephedrine: 5-8 hours (longer in alkaline urine). Context: Half-life prolonged in renal impairment.
Primarily hepatic via CYP3A4 and CYP3A5 to norbuprenorphine (active metabolite); also undergoes glucuronidation.
ibuprofen: primarily hepatic via CYP2C9; phenylephrine: primarily hepatic via monoamine oxidase (MAO) and sulfation
Approximately 60-80% of a dose is excreted renally as unchanged drug, with 20-40% eliminated via biliary/fecal routes.
Renal: ~90% as unchanged drug and metabolites (ibuprofen: <10% unchanged, pseudoephedrine: 43-96% unchanged). Biliary/fecal: minimal (<5%).
Approximately 95-98% bound to plasma proteins, primarily albumin.
Ibuprofen: >99% bound to albumin. Pseudoephedrine: 20-30% bound to albumin.
Volume of distribution is approximately 2-3 L/kg, indicating extensive tissue distribution beyond plasma volume.
Ibuprofen: 0.1-0.2 L/kg (low, reflects high protein binding). Pseudoephedrine: 2.6-3.5 L/kg (extensive tissue distribution).
Oral bioavailability is approximately 70-80%.
Oral: Ibuprofen ~80-100% (high), Pseudoephedrine ~100% (high).
e GFR <45 m L/min/1.73m²: contraindicated. e GFR ≥45: no adjustment.
Avoid use if Cr Cl <30 m L/min. For Cr Cl 30-59 m L/min, use lowest effective dose and shortest duration.
Child-Pugh Class A: no adjustment; Class B: reduce to 200 mg once daily; Class C: contraindicated.
Avoid use in severe hepatic impairment (Child-Pugh class C). For moderate impairment (Child-Pugh class B), use with caution and at the lowest effective dose.
Not recommended for patients under 18 years; safety and efficacy not established.
Not recommended in children under 12 years of age due to phenylephrine component. For children 12 years and older, same as adult dosing.
No specific dose adjustment; monitor renal function and use caution due to increased risk of adverse effects.
Start at the low end of dosing range; avoid use in patients 65 years and older if possible due to increased risk of adverse effects; if necessary, use lowest effective dose for shortest duration.
Risk of respiratory depression, especially in non-opioid-tolerant patients. Risk of neonatal opioid withdrawal syndrome with prolonged use during pregnancy. Risk of serious injury or death due to accidental exposure in children.
ibuprofen carries a black box warning for increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal, and for serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines
Respiratory depression, particularly in the first 24-72 hours of treatment; caution in patients with pulmonary disease. Risk of QT prolongation. Adrenal insufficiency. Severe hypotension. Risk of misuse, abuse, and addiction. Tolerance and physical dependence.
cardiovascular risk,gastrointestinal risk,renal effects,avoid concomitant use of other NSAIDs,hypertension,hyperthyroidism,diabetes,heart disease,use with MAOIs may cause hypertensive crisis
Hypersensitivity to buprenorphine or any component of the formulation. Severe respiratory insufficiency. Acute or severe bronchial asthma. Gastrointestinal obstruction, including paralytic ileus.
hypersensitivity to ibuprofen, phenylephrine, or any component,history of asthma, urticaria, or allergic-type reactions to aspirin or other NSAIDs,perioperative pain in setting of coronary artery bypass graft (CABG) surgery,severe hypertension,severe coronary artery disease,use of MAOIs or within 14 days of stopping MAOIs
No significant food interactions. Grapefruit juice may increase buprenorphine levels; avoid large quantities.
Avoid alcohol consumption due to increased risk of GI bleeding and liver damage. No specific food interactions; take with food or milk to reduce stomach upset. Caffeine may exacerbate pseudoephedrine's stimulant effects; limit caffeine intake.
Supr ENza (testosterone) is contraindicated in pregnancy due to virilization of female fetus. First trimester: high risk of clitoromegaly, labial fusion, and urogenital sinus abnormalities. Second and third trimesters: risk of continued virilization, including phallic enlargement and ambiguous genitalia. Fetal growth restriction may occur.
First trimester: Avoid due to potential increased risk of cardiac defects and gastroschisis from NSAIDs. Second trimester: Use with caution; ibuprofen may cause oligohydramnios and premature ductus arteriosus constriction. Third trimester: Contraindicated due to risk of premature closure of ductus arteriosus, oligohydramnios, and neonatal renal impairment. Phenylephrine: Limited human data; animal studies show fetal abnormalities at high doses; avoid in first trimester due to potential vascular disruption.
Testosterone is present in breast milk; M/P ratio not reported. Avoid breastfeeding due to potential for androgenization of the infant. Use only if clearly needed and no safer alternative.
Ibuprofen: Excreted into breast milk in low amounts (M/P ratio ~0.07). Compatible with breastfeeding; minimal infant exposure. Phenylephrine: Not known if excreted in breast milk; M/P ratio unknown. Avoid due to potential for infant hypertension and irritability. Alternative decongestants preferred.
Not applicable; Supr ENza is contraindicated in pregnancy. No dose adjustments are recommended as use is avoided entirely.
Pharmacokinetic changes in pregnancy: Increased volume of distribution and clearance for ibuprofen may require higher doses, but avoid due to fetal risks. No standard dose adjustment recommended; use lowest effective dose for shortest duration. Phenylephrine: No specific dosing adjustments in pregnancy; avoid use due to limited safety data.
SUPRENZA (buprenorphine/naloxone) sublingual film is used for opioid dependence. Monitor for respiratory depression especially when combined with benzodiazepines or alcohol. The naloxone component is poorly absorbed sublingually but precipitates withdrawal if injected. Administer only after clear signs of withdrawal to avoid precipitated withdrawal. Adjust dose in hepatic impairment as buprenorphine is hepatically metabolized.
Advil Congestion Relief combines ibuprofen (NSAID) and pseudoephedrine (decongestant). Ibuprofen can cause nephrotoxicity; pseudoephedrine can elevate blood pressure and heart rate. Avoid in patients with uncontrolled hypertension, severe CAD, or MAOI use within 14 days. Use with caution in elderly due to increased risk of GI bleeding and CNS effects. Not recommended for children under 12 years.
Take exactly as prescribed; do not increase dose or frequency without consulting your doctor.,Place film under the tongue until fully dissolved; do not chew or swallow.,Avoid alcohol and benzodiazepines as they can cause severe respiratory depression.,Keep out of reach of children; accidental exposure can be fatal.,Do not abruptly stop; withdrawal symptoms may occur.,Store at room temperature away from moisture and heat.
Do not take more than directed; do not use with other products containing ibuprofen or other NSAIDs (e.g., naproxen, aspirin) due to increased risk of stomach bleeding.,Avoid alcohol while taking this medication to reduce the risk of stomach irritation and bleeding.,Pseudoephedrine may cause insomnia, nervousness, or dizziness; take the last dose at least 4-6 hours before bedtime.,Stop use and consult a doctor if symptoms persist after 5 days (fever >3 days), if new symptoms appear, or if you experience signs of stomach bleeding (black/bloody stools, vomit with blood/coffee-grounds).,Do not use if you have heart disease, high blood pressure, thyroid disease, diabetes, glaucoma, or difficulty urinating due to an enlarged prostate unless directed by a doctor.
