AEROSEB-HC (hydrocortisone/iodoquinol) exerts anti-inflammatory, antipruritic, and antifungal actions. Hydrocortisone suppresses inflammatory mediators via glucocorticoid receptor binding, while iodoquinol provides antimicrobial activity against dermatophytes and bacteria.
Corticosteroid that binds to glucocorticoid receptors, modulating gene transcription to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress inflammatory cell migration and cytokine production.
FDA-approved for the treatment of eczematous dermatitis, atopic dermatitis, and other glucocorticoid-responsive dermatoses complicated by fungal or bacterial infections
Relief of inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses (e.g., psoriasis, eczema, contact dermatitis)
AEROSEB-HC (hydrocortisone/iodoquinol) topical cream: Apply a thin film to affected area twice daily for up to 7 days. Not for ophthalmic or oral use.
Topical: Apply a thin film to affected skin areas twice daily. Maximum 60 g per week. Use for no longer than 2 consecutive weeks.
1.5-2 hours (terminal) after intravenous administration; prolonged in hepatic impairment.
Terminal elimination half-life is approximately 2–4 hours, but following topical application, systemic half-life may be prolonged due to continuous absorption from the skin.
Hydrocortisone is primarily hepatic via CYP3A4; iodoquinol is not extensively metabolized, with partial glucuronidation and enterohepatic circulation.
Primarily hepatic metabolism via CYP3A4; metabolites are excreted renally.
Renal (primarily as metabolites; <5% unchanged); fecal (biliary excretion of metabolites).
Primarily renal; <5% fecal. About 40% of a dose is excreted in urine as unchanged drug and glucuronide conjugates.
90-95% (albumin and corticosteroid-binding globulin).
Approximately 95–99% bound to plasma proteins, primarily albumin and corticosteroid-binding globulin.
0.4-0.6 L/kg; indicates distribution into total body water and tissues.
Apparent volume of distribution is about 0.14–0.3 L/kg, indicating extensive tissue distribution.
Oral: 80-90%; Intramuscular: 100%; Intravenous: 100%.
Topical: Bioavailability is high but variable due to skin barrier; systemic absorption ranges from 0.5% to 2% with intact skin, higher with occlusion or inflamed skin. Intralesional: Complete systemic absorption.
No adjustment required for topical application. Systemic absorption is minimal; however, in severe renal impairment (GFR <30 m L/min), use caution due to potential systemic corticosteroid effects.
No adjustment required for topical use. Systemic absorption is minimal.
No specific adjustment for topical use. In Child-Pugh C cirrhosis, consider the risk of systemic corticosteroid accumulation; use with caution.
No adjustment required for topical use. Systemic absorption is minimal.
Children >2 years: Apply a thin film to affected area twice daily for up to 7 days. Avoid prolonged use, occlusion, or application to large body surface areas. Safety in children <2 years not established.
Use lowest effective dose for shortest duration. Apply sparingly to small areas. Avoid use in children <2 years of age. For children ≥2 years: apply thin film once or twice daily. Limit treatment to 5-7 days.
Elderly patients: Use the lowest effective duration and avoid prolonged use due to increased risk of skin atrophy and systemic absorption. Apply sparingly to limited areas.

No clinically significant food interactions are reported for topical hydrocortisone/pramoxine. No dietary restrictions necessary.
No known food interactions. Avoid excessive ingestion of corticosteroids systemically, but topical application does not require dietary restrictions.
FDA Pregnancy Category C. First trimester: limited data, no increased risk of major malformations identified in small studies. Second and third trimesters: potential for fetal adrenal suppression with prolonged use; avoid high doses and prolonged exposure.
Pregnancy Category C. Topical corticosteroids, including amcinonide, have not been adequately studied in pregnant women. Animal studies have shown teratogenic effects with systemic administration, but the risk with topical application is low due to minimal systemic absorption. However, prolonged or large-area use may increase systemic absorption and potential fetal risk. First trimester: Avoid unless clearly needed. Second and third trimesters: Use with caution, avoiding extensive areas, prolonged use, or occlusive dressings.
Present in breast milk in low concentrations. M/P ratio not determined. Use with caution, especially with high doses or prolonged treatment; risk of infant adrenal suppression theoretical.
No data available on excretion into breast milk. Systemic absorption after topical application is minimal but may occur with prolonged or large-area use. Caution should be exercised as a risk to the infant cannot be excluded. Use only if clearly needed and apply to smallest area for shortest duration. M/P ratio: Not established.
No standard dose adjustments required for pregnancy-related pharmacokinetic changes. Use lowest effective dose for shortest duration. Avoid high-dose or prolonged use in pregnancy.
No disease-specific pharmacokinetic changes for amcinonide. Dosing adjustments are not generally recommended, but consider using the lowest effective dose, smallest area, and shortest duration to minimize systemic absorption. Avoid occlusive dressings and use on large areas or broken skin due to increased absorption.
AEROSEB-HC is a combination aerosol foam containing hydrocortisone acetate 1% and pramoxine hydrochloride 1% for topical use. It is indicated for the relief of inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses, particularly in anogenital areas. The foam formulation enhances penetration and is less messy than ointments. Advise patients to avoid contact with eyes and mucous membranes. Use with caution in patients with skin infections or atrophy. Prolonged use in intertriginous areas may increase risk of local and systemic adverse effects.
Amcinonide is a high-potency topical corticosteroid, typically used for short-term treatment of corticosteroid-responsive dermatoses. Due to its potency, it should be applied sparingly and not used under occlusion unless directed. Avoid use on face, groin, or axillae due to increased risk of skin atrophy and systemic absorption. Monitor for local adverse effects such as striae, hypopigmentation, or rosacea-like dermatitis. Systemic absorption can occur with extensive use, particularly in children or when applied to large body surface areas.

No interactions on record
"Magnesium trisilicate, an antacid, can significantly reduce the oral bioavailability of Amcinonide, a topical corticosteroid, when administered concurrently. The mechanism involves magnesium ions chelating with the corticosteroid or altering gastrointestinal pH, thereby impairing dissolution and absorption of Amcinonide. This interaction may lead to reduced efficacy of Amcinonide therapy, particularly when higher systemic exposure is required for therapeutic effect."
"Concurrent use of topical corticosteroids like Amcinonide and systemic acetylcholinesterase inhibitors such as Pyridostigmine may potentiate adverse effects, particularly electrolyte disturbances and cardiovascular events. Pyridostigmine enhances cholinergic activity, which can lead to increased gastrointestinal motility and bronchial secretions, while Amcinonide's mineralocorticoid activity can cause sodium and water retention, aggravating fluid overload and hypertension. This interaction is clinically significant in patients with myasthenia gravis receiving Pyridostigmine, as corticosteroid-induced hypokalemia may worsen muscle weakness."
"The combination of leflunomide, an immunomodulator that inhibits dihydroorotate dehydrogenase and suppresses lymphocyte proliferation, with amcinonide, a potent topical corticosteroid, may result in additive immunosuppression, increasing the risk of serious infections, including bacterial, viral, fungal, and opportunistic infections. Systemic absorption of topical corticosteroids can occur, especially with prolonged use on large areas, damaged skin, or under occlusive dressings, potentiating adrenal suppression and other systemic corticosteroid effects. Patients receiving both agents require careful monitoring for signs of infection, adrenal insufficiency, and other adverse effects related to enhanced immunosuppression."
