Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Loteprednol etabonate is a corticosteroid that inhibits phospholipase A2, reducing arachidonic acid release and subsequent prostaglandin and leukotriene synthesis, thereby suppressing inflammation.
EMOQUETTE is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the central nervous system by inhibiting the reuptake of serotonin at the presynaptic neuronal membrane, resulting in increased serotonin concentrations in the synaptic cleft.
Post-operative ocular inflammation,Ocular itching associated with seasonal allergic conjunctivitis,Uveitis (off-label),Giant papillary conjunctivitis (off-label)
Major depressive disorder (MDD),Generalized anxiety disorder (GAD),Obsessive-compulsive disorder (OCD),Panic disorder,Premenstrual dysphoric disorder (PMDD),Post-traumatic stress disorder (PTSD)
IV: 1-2 mg every 2-4 hours as needed; maximum 8 mg/24 hours.
0.5 mg orally once daily, titrated to effect; maximum 2 mg per day.
The terminal elimination half-life is 8.2 ± 1.5 hours in healthy adults. In elderly patients (age >65 years) or those with mild-to-moderate renal impairment (Cr Cl 30–89 m L/min), the half-life may be prolonged up to 12–14 hours, necessitating dose adjustment.
Terminal elimination half-life is approximately 12–15 hours in healthy adults, allowing for twice-daily dosing; may be prolonged in renal impairment.
Loteprednol etabonate undergoes ester hydrolysis in ocular tissues and systemic circulation to its inactive metabolite, delta-1-cortienic acid etabonate; no significant CYP450 involvement.
EMOQUETTE is extensively metabolized in the liver via cytochrome P450 enzymes, primarily CYP2D6 and CYP3A4, to its active metabolite N-desmethylemoquette.
Renal excretion of unchanged drug accounts for approximately 60% of the administered dose, with an additional 25% recovered as glucuronide conjugates in urine. Biliary/fecal excretion represents about 15% of total clearance.
Renal excretion of unchanged drug accounts for approximately 60–70% of elimination; hepatic metabolism via CYP3A4 with biliary/fecal elimination of metabolites constitutes the remainder (30–40%).
Approximately 94% bound to serum albumin, with minor binding to alpha-1-acid glycoprotein (5%).
Approximately 95% bound to serum albumin and alpha-1-acid glycoprotein.
Volume of distribution is 1.2 ± 0.3 L/kg, indicating extensive tissue distribution. This large Vd suggests high penetration into extravascular tissues.
Vd is 0.8–1.2 L/kg, indicating extensive tissue distribution with penetration into peripheral compartments.
Oral bioavailability is 75% ± 10% due to first-pass hepatic metabolism. Administration with a high-fat meal increases bioavailability to 85%.
Oral bioavailability is 60–80% due to first-pass metabolism; intravenous bioavailability is 100%.
GFR 30-50 m L/min: reduce dose by 50%; GFR <30 m L/min: use with caution, not recommended.
GFR 30-89 m L/min: no adjustment needed. GFR 15-29 m L/min: reduce dose by 50%. GFR <15 m L/min: use with caution; maximum dose 1 mg per day.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: contraindicated.
Child-Pugh Class A: no adjustment. Child-Pugh Class B: reduce dose by 50%. Child-Pugh Class C: not recommended.
0.05-0.1 mg/kg IV every 4-6 hours; maximum single dose 2 mg.
Not approved for patients under 18 years. Use in adolescents (12-17 years) on a case-by-case basis at 0.25 mg once daily, titrated up to 1 mg per day.
Initiate at 0.5 mg IV, titrate carefully; monitor for sedation and hypotension.
Initiate at 0.25 mg once daily; maximum 1 mg per day due to increased sensitivity and potential for cognitive impairment.
None.
EMOQUETTE may increase the risk of suicidal thinking and behavior in children, adolescents, and young adults with major depressive disorder and other psychiatric disorders. Patients should be closely monitored for clinical worsening and emergence of suicidal thoughts and behaviors.
Prolonged use may increase intraocular pressure (IOP), glaucoma risk, and cataract formation.,Increased susceptibility to secondary ocular infections (including fungal infections).,Masking of infection or worsening of existing infections.,Corneal thinning or perforation risk in patients with corneal disease.,Systemic absorption may occur with prolonged or high-dose use.
Serotonin syndrome: life-threatening condition with co-administration of other serotonergic drugs; Discontinuation syndrome: taper dose to avoid withdrawal symptoms; Hyponatremia: monitor elderly patients; Activation of mania/hypomania: screen for bipolar disorder; Seizures: use with caution in patients with seizure disorders; Angle-closure glaucoma: avoid in patients with narrow angles.
Hypersensitivity to loteprednol etabonate or any component of the formulation,Active epithelial herpes simplex keratitis (dendritic keratitis),Fungal diseases of ocular structures,Untreated eye infections (bacterial, viral, mycobacterial)
Concomitant use with MAOIs or within 14 days of MAOI therapy; Concomitant use with pimozide; Hypersensitivity to emoquette or any excipients; Use in patients with severe renal impairment (Cr Cl < 15 m L/min)
Avoid high-sodium foods which can counteract the antihypertensive effect. Limit alcohol intake. Grapefruit juice may increase drug levels; consult your doctor.
No known food interactions. However, grapefruit juice may increase hormone levels; avoid large quantities. High-fat meals may slightly delay absorption but do not affect overall efficacy.
LO-TROL is contraindicated in pregnancy. First trimester exposure is associated with a high risk of major congenital malformations, including neural tube defects, cardiovascular anomalies, and craniofacial defects. Second and third trimester exposure may cause fetal growth restriction, oligohydramnios, and renal dysfunction. Risk is dose-dependent and increases with duration.
EMOQUETTE is classified as Pregnancy Category X. First trimester: High risk of major congenital malformations (neural tube defects, cardiovascular anomalies) based on animal studies and human case reports. Second and third trimesters: Associated with fetal growth restriction, oligohydramnios, and preterm delivery. Contraindicated in pregnancy.
LO-TROL is excreted into human breast milk. The milk-to-plasma ratio is 0.8. Due to potential for serious adverse effects in the nursing infant, including immunosuppression and growth retardation, breastfeeding is not recommended during therapy and for at least 2 weeks after the last dose.
EMOQUETTE is excreted into breast milk with an M/P ratio of 1.2. Due to potential for serious adverse reactions in the nursing infant (e.g., sedation, hypotonia), breastfeeding is not recommended during treatment and for 5 days after the last dose.
Pregnancy significantly reduces LO-TROL plasma concentrations due to increased volume of distribution and enhanced clearance. Dose adjustments should be guided by therapeutic drug monitoring, with target trough levels increased by 30-50% compared to non-pregnant patients. Initiate adjustment in the first trimester and re-evaluate monthly.
No dosing adjustment is applicable because EMOQUETTE is absolutely contraindicated in pregnancy. If exposure occurs, immediate discontinuation is required.
Monitor for signs of bronchospasm in patients with asthma or COPD. Use with caution in patients with diabetes as it may mask hypoglycemia symptoms. Taper dose gradually over 1-2 weeks to avoid rebound hypertension.
EMOQUETTE is a novel oral contraceptive. Counsel patients that efficacy may be reduced by CYP3A4 inducers such as rifampin or St. John's Wort. Breakthrough bleeding is common in first 3 cycles but typically resolves. Administer at same time daily to maintain stable hormone levels.
Do not stop taking this medication abruptly; gradual dose reduction is necessary.,Avoid driving or operating machinery until you know how this medication affects you, as it may cause dizziness or fatigue.,Monitor your blood pressure regularly and report any significant changes.,Take this medication exactly as prescribed; do not double up on missed doses.,Avoid alcohol consumption as it may increase the risk of hypotension.
Take one tablet at the same time every day, with or without food.,If you miss a dose, take it as soon as you remember and use backup contraception for 7 days.,Common side effects include nausea, breast tenderness, and spotting, especially in first few months.,Do not smoke while taking this medication; smoking increases risk of blood clots.,Contact your healthcare provider if you experience leg pain, chest pain, or sudden severe headache.
