Aclovate (alclometasone dipropionate) is a synthetic corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive properties. Its mechanism involves binding to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reducing arachidonic acid release, and decreasing prostaglandin and leukotriene synthesis.
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.
Relief of inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses (e.g., atopic dermatitis, contact dermatitis, eczema, psoriasis) - FDA approved,Off-label: Treatment of mild to moderate plaque psoriasis, seborrheic dermatitis, and lichen planus

Apply a thin film to affected skin areas twice daily. Not for ophthalmic, oral, or intravaginal use.
Topical: Apply a thin film to affected area 3-4 times daily. Dosage strength: 0.5% cream or ointment.
Terminal elimination half-life: approximately 6-8 hours after topical application; systemic absorption is minimal under normal use.
Terminal elimination half-life: 1–2 hours for hydrocortisone (active component), prolonged in liver disease or with concurrent CYP3A4 inhibitors.
Aclovate is metabolized in the skin and liver via ester hydrolysis to inactive metabolites. Systemic metabolism primarily involves cytochrome P450 enzymes (CYP3A4) for any absorbed fraction, but extensive first-pass metabolism limits systemic exposure.
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.
Renal (primarily as metabolites, <5% unchanged), biliary/fecal (minor).
Primarily hepatic metabolism (approximately 95%) followed by renal excretion of inactive metabolites (<5% unchanged). Biliary/fecal excretion is negligible.
Approximately 90%, primarily to albumin and corticosteroid-binding globulin (CBG).
Hydrocortisone is approximately 90–95% bound to corticosteroid-binding globulin (CBG, transcortin) and albumin.
Not well-characterized in topical use; after systemic absorption, Vd is approximately 1-2 L/kg, indicating distribution into tissues.
Apparent volume of distribution (Vd) is approximately 0.4–0.6 L/kg, indicating moderate tissue distribution and limited penetration into CNS.
Topical: approximately 1-3% systemic absorption on intact skin; increased up to 15% on occluded or damaged skin.
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.
No dose adjustment required. Topical use with minimal systemic absorption.
No adjustment required for topical use; systemic absorption minimal.
No dose adjustment required. Topical use with minimal systemic absorption.
No adjustment required for topical use; hepatic metabolism negligible.
Use smallest amount effective for shortest duration. Avoid prolonged use, occlusive dressings, or application to large surface areas. Safety in children <1 year not established.
Children ≥2 years: Apply a thin film to affected area 2-3 times daily. Use lowest potency preparation; avoid prolonged use.
Use with caution due to increased risk of skin atrophy and systemic absorption. Limit frequency and duration; avoid occlusive dressings.
Use lowest effective dose; monitor for skin atrophy and systemic effects due to thinner skin and increased percutaneous absorption.
No FDA black box warning.
None
Topical corticosteroids can cause hypothalamic-pituitary-adrenal (HPA) axis suppression, especially with prolonged use, large surface area, occlusion, or in pediatric patients.,Reversible HPA axis suppression may occur after discontinuation.,Systemic effects including Cushing's syndrome, hyperglycemia, and glucosuria have been reported.,Local adverse reactions: burning, itching, irritation, dryness, folliculitis, hypopigmentation, allergic contact dermatitis, maceration, secondary infection, skin atrophy, striae, and miliaria.,Use caution in patients with impaired skin integrity or areas of skin atrophy.,Pediatric patients may be more susceptible to systemic toxicity due to higher skin surface-to-body-weight ratio.
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 Aclovate.
No known food interactions with topical ALA-CORT.
Topical corticosteroids like ACLOVATE (alclometasone dipropionate) are generally considered low risk in pregnancy, but systemic absorption can occur. Class C: Fetal risk cannot be ruled out. Avoid extensive use or prolonged treatment, especially in first trimester. Second and third trimester: Use only if clearly needed, minimal area and duration.
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.
Safety unknown; likely minimal systemic absorption due to low potency. M/P ratio not established. Avoid application to breasts or large areas; use caution.
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 standard dose adjustment required; however, limit potency, frequency, and duration to lowest effective due to altered skin permeability. No pharmacokinetic changes necessitate dose change.
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.
Topical corticosteroids like Aclovate are classified as low-potency (Group VI). They are suitable for thin skin areas (e.g., face, flexures) and for children. Avoid prolonged use without interruption to minimize systemic absorption, especially in pediatric patients due to higher skin surface area-to-body weight ratio.
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.
