Edaravone is a free radical scavenger that reduces oxidative stress by trapping hydroxyl radicals, peroxynitrite, and other reactive oxygen species, thereby protecting neuronal cells from oxidative damage.
Selective serotonin reuptake inhibitor (SSRI); inhibits serotonin reuptake at the presynaptic neuron, potentiating serotonergic activity.
Treatment of amyotrophic lateral sclerosis (ALS)
Major depressive disorder,Generalized anxiety disorder,Obsessive-compulsive disorder (off-label),Panic disorder (off-label),Post-traumatic stress disorder (off-label),Premenstrual dysphoric disorder (off-label)
60 mg intravenously over 60 minutes once daily for 14 days, followed by a 14-day drug-free period, then 60 mg intravenously over 60 minutes once daily for 14 days.
10 mg orally once daily; may increase to 20 mg once daily after at least 1 week.
Terminal elimination half-life is 4.5-6 hours. In patients with moderate hepatic impairment, half-life may be prolonged up to 9 hours. No significant accumulation with twice-daily dosing.
27-32 hours (mean ~30 h); steady state reached in ~1 week; linear kinetics at therapeutic doses.
Edaravone is metabolized primarily via glucuronidation by UGT1A6, UGT1A9, and UGT2B7, and also undergoes sulfation. It is not significantly metabolized by CYP450 enzymes.
Primarily hepatic via CYP3A4 and CYP2C19; active metabolite S-desmethylcitalopram.
Primarily renal excretion as unchanged drug and metabolites (approximately 60-70% unchanged edaravone in urine). Minor fecal elimination (<10%).
Primarily renal (approx. 80% as metabolites, 8% as unchanged drug); biliary/fecal elimination accounts for ~15%.
Approximately 90-92% bound to plasma proteins, primarily to albumin.
Approximately 56% bound to plasma proteins (mainly albumin and alpha-1-acid glycoprotein).
Volume of distribution is approximately 0.2-0.3 L/kg, indicating limited extravascular distribution. Predominantly distributes in extracellular fluid.
12-26 L/kg (mean ~20 L/kg); extensive extravascular distribution consistent with high lipophilicity.
Oral bioavailability is approximately 50-60% due to first-pass metabolism. For the intravenous formulation (approved), bioavailability is 100% by definition.
Oral: approximately 80% (range 60-90%) after a single dose; food does not significantly affect absorption.
No dose adjustment required for GFR ≥30 m L/min/1.73 m². Safety and efficacy not established for GFR <30 m L/min/1.73 m²; use with caution.
No dosage adjustment for mild to moderate impairment. Not recommended for severe impairment (Cr Cl <20 m L/min).
No specific guidelines for Child-Pugh classification. Use with caution in severe hepatic impairment due to lack of data.
For Child-Pugh class A or B: 10 mg orally once daily. Use caution in severe impairment (Child-Pugh class C); limited data.
Not approved for use in pediatric patients; safety and efficacy not established.
Adolescents 12-17 years: 10 mg orally once daily. Children <12 years: not approved.
No specific dose adjustment required; pharmacokinetic studies show no significant differences in elderly patients. Monitor renal function as age-related decline may occur.
Initial 5 mg orally once daily; maximum 10 mg once daily.
None.
Increased risk of suicidal thinking and behavior in children, adolescents, and young adults with major depressive disorder and other psychiatric disorders.
Hypersensitivity reactions (e.g., urticaria, dyspnea) have been reported; discontinue if severe.,Monitor for sulfite sensitivity in patients with asthma (contains sodium bisulfite).,Renal impairment: Not recommended in severe renal impairment (Cr Cl <30 m L/min).,Hepatic impairment: Use with caution in moderate to severe hepatic impairment.
Suicidality risk in young adults,Serotonin syndrome,QT prolongation,Hyponatremia,Bleeding risk,Activation of mania/hypomania,Seizure risk,Abrupt discontinuation syndrome
Hypersensitivity to edaravone or any of its excipients.,Severe renal impairment (Cr Cl <30 m L/min).
Concurrent use of MAOIs or within 14 days of discontinuing MAOI,Concomitant use of pimozide,Hypersensitivity to escitalopram or citalopram,QT prolongation or congenital long QT syndrome (for citalopram, caution for escitalopram)
No significant food interactions reported. No dietary restrictions known.
Grapefruit juice may increase escitalopram exposure; avoid concurrent use. Alcohol can potentiate central nervous system depression; limit or avoid alcohol consumption. No significant food interactions; may be taken with or without food.
Edaravone is not recommended during pregnancy due to lack of adequate human data. In animal studies, intravenous administration during organogenesis resulted in increased fetal malformations (e.g., skeletal abnormalities) at doses below the human equivalent. Risk cannot be excluded for all trimesters.
First trimester: Epidemiologic studies have shown a small increased risk of congenital cardiac defects (primarily ventricular septal defects) with exposure, with an absolute risk of approximately 1-2%. Second/third trimester: Late pregnancy exposure may increase risk for persistent pulmonary hypertension of the newborn (PPHN) and serotonin syndrome in the neonate. Third trimester use may lead to neonatal adaptation syndrome including irritability, respiratory distress, and feeding difficulties.
No data on edaravone excretion in human milk. M/P ratio unknown. Due to potential for adverse effects in nursing infants, breastfeeding is not recommended during treatment and for at least 2 weeks after last dose.
Escitalopram is excreted into human breast milk with a milk-to-plasma ratio (M/P) of approximately 2.0. Infant serum levels are typically low, but some cases of adverse effects such as irritability, feeding problems, and sleep disturbance have been reported. The American Academy of Pediatrics considers escitalopram compatible with breastfeeding, but caution is advised, especially in premature or compromised infants.
No pharmacokinetic data in pregnancy; dose adjustments are not established. Use only if potential benefit justifies risk to fetus; consider alternative treatments if pregnancy occurs.
Pharmacokinetic changes during pregnancy (increased volume of distribution, increased clearance) may require dose adjustments. Escitalopram clearance increases by approximately 50% in the third trimester. Dose increases may be needed to maintain efficacy, with gradual reduction postpartum to pre-pregnancy dose over 2-4 weeks. Therapeutic drug monitoring of escitalopram and its metabolite S-DCT is recommended if available, targeting trough levels of 15-80 ng/m L.
Monitor for hypersensitivity reactions, including anaphylaxis; edema and gait disturbance are common adverse effects. Avoid use in patients with severe hepatic impairment. Administer intravenous infusion over 60 minutes; do not mix with other medications in the same bag. Renal function monitoring recommended.
LEXAPRO (escitalopram) is the S-enantiomer of citalopram with less cytochrome P450 inhibition, minimizing drug interactions compared to racemic citalopram. QT prolongation risk is dose-dependent; maximum dose is 20 mg/day. Avoid co-administration with MAOIs and other serotonergic drugs due to serotonin syndrome risk. Abrupt discontinuation may cause withdrawal symptoms; taper over 1-2 weeks. Onset of therapeutic effect is 2-4 weeks. Use with caution in hepatic impairment (max dose 10 mg) and elderly patients.
