Treatment of lower extremity diabetic neuropathic ulcers that extend into the subcutaneous tissue or beyond and have adequate blood supply,Off-label: Treatment of pressure ulcers, venous stasis ulcers
Spasticity due to multiple sclerosis (FDA approved),Spinal cord injury (FDA approved),Intrathecal use for severe spasticity of cerebral origin (off-label),Hiccups (off-label),Alcohol withdrawal syndrome (off-label),Trigeminal neuralgia (off-label)
1 drop in the affected eye(s) twice daily, approximately 6 hours apart.
Initial: 5 mg orally 3 times daily; increase by 5 mg per dose every 3 days to max 80 mg/day (20 mg 4 times daily). Intrathecal: initial test dose 50-100 mcg; for continuous infusion, daily dose typically 300-800 mcg.
Terminal elimination half-life of Cenegermin is approximately 12 hours following topical ocular administration, supporting once-daily dosing
Terminal half-life: 2.5-4 hours (young adults), 4-8 hours (elderly); clinical context: requires frequent dosing for spasticity.
Becaplermin is a protein that is expected to be degraded into small peptides and amino acids via general protein catabolism; specific hepatic metabolism is not a significant pathway.
Metabolized via hepatic deamination by transaminase; primarily excreted unchanged in urine (approximately 70-80%), with minor hepatic metabolism.
Primarily renal elimination of the active metabolite (Cenegermin) as small peptides and amino acids; unchanged drug excretion is negligible
Renal: 70-80% unchanged; fecal: <5%; biliary: minimal.
Cenegermin binding to plasma proteins is minimal (<10%) due to its small protein nature
30-35% bound to albumin.
Vd not determined for topical ocular route; systemic exposure is low, with Vd estimated less than 0.1 L/kg based on limited systemic absorption
Vd: 0.5-0.7 L/kg; indicates distribution into total body water.
Topical ocular: Systemic bioavailability is negligible (<1%) due to low corneal penetration and extensive proteolysis at the ocular surface
Oral: 70-85% with high variability; intrathecal: 100%.
No dose adjustment required for renal impairment.
Cr Cl 30-50 m L/min: reduce dose by 50%; Cr Cl <30 m L/min: avoid use or use with extreme caution, reduce dose by 75%.
No dose adjustment required for hepatic impairment.
No specific guidelines; use with caution due to potential for increased sedation/neurotoxicity.
Safety and efficacy in pediatric patients have not been established.
Children 2-7 years: initial 2.5 mg orally 4 times daily, increase by 2.5 mg/dose every 3 days to max 40 mg/day; children ≥8 years: initial 5 mg orally 3 times daily, increase as in adults to max 60 mg/day.
No specific dose adjustment required; use same dosing as adults.
Start at low end of dosing range (5 mg twice daily), titrate slowly due to increased risk of sedation, weakness, and cognitive impairment.
OXERVATE has been associated with an increased risk of mortality from secondary malignancies in patients who have had a malignant neoplasm. The drug should not be used in patients with active malignancy.
Abrupt discontinuation may cause withdrawal symptoms including hallucinations, seizures, and life-threatening hyperpyrexia; taper dose gradually.
Increased risk of malignancy in patients with a history of malignancy; application to ulcers with malignant cells may promote tumor growth; use only on clean, non-infected ulcers; monitor for signs of infection; avoid application to wounds with exposed bone, tendon, or joint capsule.
May cause CNS depression (drowsiness, sedation) and impair ability to drive or operate machinery.,Risk of withdrawal syndrome including fever, altered mental status, and autonomic instability upon abrupt cessation.,Use with caution in patients with renal impairment; dose adjustment required.,May exacerbate psychiatric disorders; monitor for hallucinations, confusion.,Risk of respiratory depression when combined with other CNS depressants.
Known hypersensitivity to becaplermin or any product component; active neoplasm at the application site; patients with a history of malignancy (relative contraindication based on black box warning).
Hypersensitivity to baclofen.,Intrathecal formulation is contraindicated in patients with active infection or bleeding disorders at lumbar puncture site.,Women who are breastfeeding (relative contraindication).
None known; no significant food interactions reported.
No specific food interactions. Avoid alcohol due to additive CNS depression.
OXERVATE contains cenegermin, a recombinant human nerve growth factor. No adequate and well-controlled studies in pregnant women. Animal reproductive studies have not been conducted. Risk cannot be ruled out; use only if potential benefit justifies potential risk to fetus. First trimester: unknown risk; second and third trimesters: unknown risk.
First trimester: Limited human data; animal studies show increased fetal malformations (omphalocele, exencephaly) at doses equivalent to human therapeutic range. Second and third trimesters: Risk of neonatal withdrawal (hypertonia, seizures) with chronic maternal use. Avoid unless benefit outweighs risk.
No data on presence in human milk, effects on breastfed infant, or milk production. Caution advised; M/P ratio unknown.
Baclofen excreted into breast milk in low concentrations (M/P ratio approximately 0.43). Relative infant dose estimated 0.9% of maternal weight-adjusted dose. Considered compatible with breastfeeding, but monitor infant for sedation and hypotonia.
No pharmacokinetic studies in pregnancy; dose adjustments not established. Use standard dosing with caution.
No specific dose adjustments recommended. Increased renal blood flow and GFR in pregnancy may reduce baclofen levels; monitor clinical effect and adjust dose as needed. Avoid abrupt discontinuation due to risk of maternal withdrawal and rebound spasticity.
OXERVATE (cenegermin-bkbj) is a recombinant human nerve growth factor for neurotrophic keratitis. Administer as one drop in the affected eye(s) six times daily at 2-hour intervals for 8 weeks. Refrigerate at 2-8°C; do not freeze. Protect from light. Discard unused drops after 1 week of first opening. Monitor for corneal epithelial defect closure. Use with caution in patients with active ocular infections or inflammation.
Abrupt withdrawal can cause severe rebound spasticity, fever, and rhabdomyolysis; taper by 5-10 mg/week. Intrathecal baclofen pumps require careful monitoring for overdose (respiratory depression) or withdrawal. Use with caution in renal impairment (dose adjust for Cr Cl <30 m L/min).
Wash hands before each use.,Instill one drop in the affected eye(s) every 2 hours, 6 times daily.,Refrigerate the medication at all times; do not freeze.,Use within 1 week after opening the vial.,Avoid touching the dropper tip to any surface.,Do not use contact lenses during treatment.,Report any eye pain, redness, or vision changes immediately.,Complete the full 8-week course even if symptoms improve.
Do not stop taking baclofen suddenly; sudden discontinuation can cause serious withdrawal symptoms including hallucinations, seizures, and high fever.,Avoid alcohol and CNS depressants as they increase sedation and risk of falls.,May cause dizziness or drowsiness; avoid driving or operating machinery until you know how it affects you.,Take exactly as prescribed; missed doses can lead to muscle spasms or withdrawal.,Report any unusual muscle stiffness, rapid heart rate, or dark urine immediately.
No interactions on record
"Sevoflurane enhances the inhibitory effects of baclofen on the central nervous system by potentiating GABA-B receptor activity, leading to an increased risk of profound sedation, respiratory depression, and hypotension. This synergistic interaction can result in prolonged recovery from anesthesia and the need for ventilatory support. Clinically, patients may exhibit exaggerated muscle relaxation and a delayed emergence from anesthesia, particularly at higher doses of either agent."
"Concomitant use of etidocaine, an amide-type local anesthetic that blocks voltage-gated sodium channels, and baclofen, a GABAB receptor agonist used for muscle spasticity, may lead to additive central nervous system (CNS) depression and respiratory depression. This interaction results from synergistic depressant effects on the brainstem and spinal cord, increasing the risk of sedation, dizziness, ataxia, and impaired consciousness. Clinically, patients may experience excessive drowsiness, respiratory compromise, and impaired motor coordination, particularly in the elderly or those with pre-existing renal impairment where baclofen accumulation is more likely."
"The coadministration of Baclofen and Metaxalone results in additive central nervous system (CNS) depression due to their shared pharmacodynamic effects on GABAergic and sedative pathways. This combination can potentiate sedation, dizziness, ataxia, and respiratory depression, particularly in elderly patients or those with renal impairment. Clinical outcomes may include increased risk of falls, cognitive impairment, and impaired motor coordination, necessitating cautious dose titration."
