Topical corticosteroid that induces phospholipase A2 inhibitory proteins, collectively called lipocortins, which inhibit the release of arachidonic acid, thereby reducing prostaglandin and leukotriene synthesis, and exerting anti-inflammatory, antipruritic, and vasoconstrictive effects.
Combination of fluticasone furoate, a corticosteroid that binds to glucocorticoid receptors to inhibit inflammatory gene transcription, and vilanterol, a long-acting beta2-adrenergic agonist that activates adenylate cyclase leading to bronchodilation.
Relief of inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses (FDA),Off-label: Atopic dermatitis, psoriasis, contact dermatitis, lichen planus, discoid lupus erythematosus
Maintenance treatment of chronic obstructive pulmonary disease (COPD) including chronic bronchitis and/or emphysema,Maintenance treatment of asthma in patients aged 18 years and older
Topical: Apply a thin film to affected area 3-4 times daily. Dosage strength: 0.5% cream or ointment.
One inhalation (100 mcg fluticasone furoate / 25 mcg vilanterol) once daily via oral inhalation.
Terminal elimination half-life: 1–2 hours for hydrocortisone (active component), prolonged in liver disease or with concurrent CYP3A4 inhibitors.
Fluticasone furoate: 24 hours (supports once-daily dosing). Vilanterol: 11 hours (supports once-daily dosing).
Topically applied; systemic absorption is minimal but can be increased with use on large areas, occlusive dressings, or damaged skin. Absorbed portion is metabolized primarily in the liver via hepatic microsomal enzymes (CYP3A4) and excreted by the kidneys.
Fluticasone furoate: primarily metabolized by CYP3A4; Vilanterol: primarily metabolized by CYP3A4.
Primarily hepatic metabolism (approximately 95%) followed by renal excretion of inactive metabolites (<5% unchanged). Biliary/fecal excretion is negligible.
Fluticasone furoate is eliminated primarily via fecal excretion (approximately 101% of an oral dose) due to biliary clearance, with minimal renal excretion (<1%). Vilanterol is eliminated via metabolism and subsequent renal (approximately 70% of an IV dose) and fecal (approximately 30% of an IV dose) excretion.
Hydrocortisone is approximately 90–95% bound to corticosteroid-binding globulin (CBG, transcortin) and albumin.
Fluticasone furoate: >99.8% (primarily albumin). Vilanterol: approximately 94% (albumin and alpha-1-acid glycoprotein).
Apparent volume of distribution (Vd) is approximately 0.4–0.6 L/kg, indicating moderate tissue distribution and limited penetration into CNS.
Fluticasone furoate: approximately 4.5 L/kg (extensive tissue distribution). Vilanterol: approximately 165 L (large Vd, extensive distribution).
Topical: Bioavailability is negligible (<1%) through intact skin; may increase (up to 30%) with damaged skin or occlusive dressings. Rectal: Bioavailability is approximately 10–20% via mucosal absorption, with first-pass metabolism reducing systemic exposure.
Inhaled: Fluticasone furoate absolute bioavailability approximately 15% (lung deposition). Vilanterol absolute bioavailability approximately 27% (lung deposition). Oral bioavailability is negligible for both (<2% for fluticasone furoate, <5% for vilanterol).
No adjustment required for topical use; systemic absorption minimal.
No dosage adjustment required for renal impairment. However, use with caution in severe renal impairment due to potential for increased systemic exposure.
No adjustment required for topical use; hepatic metabolism negligible.
Child-Pugh Class A and B: No dosage adjustment recommended. Child-Pugh Class C: Contraindicated.
Children ≥2 years: Apply a thin film to affected area 2-3 times daily. Use lowest potency preparation; avoid prolonged use.
Indicated for children aged 5 years and older with asthma. For ages 5-11: one inhalation of 100 mcg/25 mcg once daily. For ages 12 and older: same as adult dosing.
Use lowest effective dose; monitor for skin atrophy and systemic effects due to thinner skin and increased percutaneous absorption.
No dose adjustment required for elderly patients. Use with caution due to increased risk of comorbidities and adverse effects.
None
Long-acting beta2-adrenergic agonists (LABAs) increase the risk of asthma-related death. Use only as additional therapy for patients not adequately controlled on a long-term asthma control medication or whose disease severity warrants initiation of both an inhaled corticosteroid and a LABA.
Systemic absorption may cause reversible HPA axis suppression,Cushing's syndrome, hyperglycemia, and glucosuria with prolonged use,Local adverse reactions: atrophy, striae, telangiectasias, acneiform eruptions, perioral dermatitis,May mask signs of infection,Use with caution in pediatric patients due to increased susceptibility to HPA axis suppression,Avoid use on face, intertriginous areas, and under occlusive dressings unless directed by physician

No known food interactions with topical ALA-CORT.
No specific food interactions reported. However, grapefruit juice may increase systemic exposure to fluticasone furoate via CYP3A4 inhibition; although clinical significance is low, avoid excessive grapefruit consumption. No dietary restrictions necessary.
FDA Pregnancy Category C. First trimester: No adequate human studies; animal studies show increased risk of cleft palate. Second/third trimester: Risk of intrauterine growth restriction, adrenal suppression in fetus. Avoid prolonged use.
Insufficient human data; based on animal studies, corticosteroids (fluticasone furoate) and LABA (vilanterol) show no major teratogenicity but may cause fetal growth restriction at high systemic exposures. Avoid in first trimester unless benefit outweighs risk; use lowest effective dose in later trimesters.
Provides small amounts in breast milk; M/P ratio unknown. At maternal doses up to 80 mg/day, no adverse effects reported in infants. Consider risk-benefit with high doses or prolonged therapy.
No data on drug excretion in human milk; M/P ratio unknown. Corticosteroids and LABAs are expected to be present in low concentrations. Caution if breastfeeding, especially in preterm infants. Consider alternative therapies.
Pregnancy-induced pharmacokinetic changes (increased clearance, volume of distribution) may require increased dosing, but clinical response should guide adjustment. Avoid high doses and prolonged use.
No specific dose adjustments required due to pregnancy-induced pharmacokinetic changes, but use lowest effective dose to maintain asthma control due to potential fetal risk.
ALA-CORT (hydrocortisone acetate 2.5% and pramoxine HCl 1%) is a topical corticosteroid with anesthetic. Use for short-term relief of pruritus and inflammation in corticosteroid-responsive dermatoses. Avoid prolonged use on intertriginous or occluded areas. Limit to <2 weeks continuous use in adults to avoid skin atrophy. Not recommended for children <2 years.
Breo Ellipta (fluticasone furoate/vilanterol) is an ICS/LABA combination indicated for maintenance treatment of COPD and asthma. It is not for acute bronchospasm. The ELLIPTA inhaler is a once-daily, dry powder inhaler; each actuation delivers a fixed dose. Rinse mouth with water after use without swallowing to reduce oral candidiasis.
