Warnings
Black Box Warnings
These warnings are specific for Caldolor
Cardiovascular Risk
- NSAIDs may increase risk of serious cardiovascular thrombotic events, myocardial infarction (MI), and stroke, which can be fatal
- Risk may increase with duration of use
- Patients with risk factors for or with existing cardiovascular disease may be at greater risk
- NSAIDs are contraindicated for perioperative pain in the setting of coronary artery bypass graft (CABG) surgery (increased risk of MI and stroke)
Gastrointestinal Risk
- NSAIDs increase risk of serious GI adverse events including bleeding, ulceration, and
- perforation of the stomach or intestines, which can be fatal
- GI adverse events may occur at any time during use and without warning symptoms
- Elderly patients are at greater risk for serious GI events
Contraindications
Caldolor
- Hypersensitivity
- History of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs
- Coronary artery bypass graft (CABG): Increased risk of MI and stroke if administered in the first 10-14 days following CABG
NeoProfen
- Untreated proven or suspected infection
- Congenital heart disease where PDA patency is necessary for satisfactory pulmonary or systemic blood flow (eg, pulmonary atresia, severe tetralogy of Fallot, severe coarctation of the aorta)
- Bleeding, especially active intracranial hemorrhage or GI bleeding
- Thrombocytopenia; coagulation defects
- Necrotizing enterocolitis
- Significant renal impairment
Cautions
Caldolor
- Increased risk for serious CV thrombotic events, myocardial infarction (MI), and stroke (use lowest effective dose for shortest duration possible); additionally, increased MI and stroke if administered in the first 10-14 days following CABG (see Contraindications)
- Risk of GI ulceration, bleeding, and perforation
- May cause borderline LFT elevations; rare reports of notable ALT or AST (ie, 3xULN) or severe hepatic reactions (eg, jaundice, fulminant hepatitis, liver necrosis, hepatic failure)
- May cause new onset hypertension, or exacerbation of existing hypertension
- Fluid retention and edema observed; caution in patients with heart failure
- Long-term administration of NSAIDs may result in renal papillary necrosis and other renal injury; patients at greatest risk include the elderly, or those with impaired renal function, hypovolemia, heart failure, liver dysfunction, salt depletion, and individuals taking diuretics, ACE inhibitors, or ARBs
- Anaphylactoid reactions reported (see Contraindications)
- Serious skin reactions may occur (eg, exfoliative dermatitis, Stevens-Johnson syndrome, toxic epidermal necrolysis)
- Avoid in pregnancy after 30 weeks gestation; associated with premature closure of the ductus arteriosus
- Diminishes utility of inflammation and fever as diagnostic signs for infection
- Must be diluted prior to use; infusing undiluted may result in hemolysis
- Patients with asthma may have aspirin-sensitive asthma; use of aspirin or NSAIDs may cause severe bronchospasm in these patients
- Blurred or diminished vision, scotomata, and changes in color vision reported with oral ibuprofen
- Aseptic meningitis with fever and coma observed with oral ibuprofen therapy
NeoProfen
- Diminishes utility of inflammation and fever as diagnostic signs for infection
- Inhibits platelet aggregation; caution with underlying hemostatic defects (see Contraindications)
- Displaces bilirubin from albumin binding-sites
- Administer cautiously to avoid extravasation
Pregnancy & Lactation
Pregnancy Category: C; D from 30 weeks of gestation onward, may cause premature closure of the ductus arteriosus
The Quebec Pregnancy Registry identified 4705 women who had spontaneous abortions by 20 weeks' gestation; each case was matched to 10 control subjects (n=47,050) who had not had spontaneous abortions; exposure to nonaspirin NSAIDs during pregnancy was documented in approximately 7.5% of cases of spontaneous abortions and in approximately 2.6% of controls. (CMAJ, September 6, 2011; DOI:10.1503/cmaj.110454)
Lactation: excreted into breast milk; not recommended (AAP Committee states "compatible with nursing")
Pregnancy Categories
A:Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B:May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.
C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.
D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.
X:Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.
NA:Information not available.
Pharmacology
Mechanism of Action
Elicits anti-inflammatory, analgesic, and antipyretic activity
Inhibits synthesis of prostaglandins in body tissues by inhibiting at least 2 cyclooxygenase isoenzymes, cyclooxygenase-1 (COX-1) and -2 (COX-2)
May inhibit chemotaxis, may alter lymphocyte activity, decrease proinflammatory cytokine activity, and may inhibit neutrophil aggregation; these effects may contribute to its anti-inflammatory activity
Absorption
Peak Plasma Concentration: 39.2-72.6 mcg/mL (Caldolor)
AUC: 109.3-192.8 mcg•h/mL (Caldolor)
Distribution
Protein Bound: >99% (saturable at >20 mcg/mL)
Vd: 320 mL/kg (NeoProfen)
Metabolism
Racemic mixture of R- and S-isomers; in vivo and in vitro studies indicate the S-isomer is active and the R-form, while thought to be pharmacologically inactive, is slowly and incompletely (~60%) interconverted into the active S species in adults
Hepatic CYP2C9 (primarily); CYP2C19 substrate
Metabolites: (+)-2-[4'-(2-hydroxy-2-methylpropyl) phenyl] propionic acid (metabolite A), (+)-2-[4'-(2-carboxypropyl) phenyl] propionic acid (metabolite B)
Elimination
Half-life: 2.22-2.44 hr (Caldolor); >10 times that of adults (neonates), 43.1 hr (3 days old) and 26.8 hr (5 days old)
Renal clearance: 3 mL/kg/hr (NeoProfen); increases rapidly postnatally by 0.5 mL/kg/hr per day
Excretion: Urine (predominantly) and bile
