Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Beta-2 adrenergic receptor agonist; stimulates adenylate cyclase, increasing c AMP, leading to bronchodilation and inhibition of mast cell mediator release.
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.
FDA-approved: Treatment of asthma (acute bronchospasm and prophylaxis), COPD exacerbations,Off-label: Preterm labor tocolysis, hyperkalemia
FDA-approved for the treatment of eczematous dermatitis, atopic dermatitis, and other glucocorticoid-responsive dermatoses complicated by fungal or bacterial infections
2.5 mg via nebulization every 4-6 hours as needed for bronchospasm; or 90 mcg (2 inhalations) via metered-dose inhaler every 4-6 hours.
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.
Terminal elimination half-life of 3-6 hours; clinical context: requires frequent dosing (every 4-6 hours) for sustained bronchodilation.
1.5-2 hours (terminal) after intravenous administration; prolonged in hepatic impairment.
Metabolized by catechol-O-methyltransferase (COMT), monoamine oxidase (MAO), and sulfate conjugation in the gastrointestinal tract and liver.
Hydrocortisone is primarily hepatic via CYP3A4; iodoquinol is not extensively metabolized, with partial glucuronidation and enterohepatic circulation.
Primarily renal excretion of unchanged drug and sulfate conjugates; 60-70% as unchanged drug, 15-20% as sulfate metabolites, minor biliary/fecal elimination (<5%).
Renal (primarily as metabolites; <5% unchanged); fecal (biliary excretion of metabolites).
50-60% bound to albumin.
90-95% (albumin and corticosteroid-binding globulin).
4-5 L/kg (large Vd indicating extensive tissue distribution, particularly lung tissue).
0.4-0.6 L/kg; indicates distribution into total body water and tissues.
Inhalation: 10-20% (due to deposition and first-pass metabolism from swallowed portion). Oral: 40-50% (significant first-pass metabolism to sulfate conjugates).
Oral: 80-90%; Intramuscular: 100%; Intravenous: 100%.
No dose adjustment required for GFR ≥30 m L/min; for GFR <30 m L/min, reduce dose by 50% and monitor for systemic effects.
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 specific Child-Pugh-based adjustments; caution in severe hepatic impairment due to reduced clearance; consider dose reduction of 50% in Child-Pugh Class C.
No specific adjustment for topical use. In Child-Pugh C cirrhosis, consider the risk of systemic corticosteroid accumulation; use with caution.
0.15 mg/kg/dose (max 5 mg) via nebulization every 4-6 hours; or 1-2 inhalations (90 mcg each) via MDI every 4-6 hours as needed.
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; potential for increased cardiovascular sensitivity; consider starting at 1.25 mg nebulization or 1 inhalation every 6 hours, titrate cautiously.
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.
Increased risk of asthma-related death with beta-2 agonists; use inhaled beta-2 agonists alone for asthma is not recommended without concomitant inhaled corticosteroid.
None
Paradoxical bronchospasm, cardiovascular effects (tachycardia, hypertension, arrhythmias), hypokalemia, hyperglycemia, immediate hypersensitivity reactions, and worsening of asthma symptoms.
Prolonged use may lead to systemic corticosteroid effects, including HPA axis suppression, Cushing's syndrome, and hyperglycemia.,Risk of secondary infection due to immunosuppression.,Local adverse reactions such as skin atrophy, striae, and perioral dermatitis.,Avoid use in diaper area or under occlusive dressings.
Hypersensitivity to beta-2 agonists or any component of the formulation; use in patients with tachyarrhythmias (e.g., atrial fibrillation with rapid ventricular response) unless benefit outweighs risk.
Hypersensitivity to any component (hydrocortisone, iodoquinol, or sulfites).,Viral or fungal infections without appropriate antimicrobial coverage.,Immunocompromised patients (systemic use relative).,Pregnancy (category C, use only if benefit outweighs risk).
No significant food interactions. Avoid caffeine-containing foods and beverages if experiencing palpitations or tremors. Maintain adequate potassium intake as beta-2 agonists can cause hypokalemia.
No clinically significant food interactions are reported for topical hydrocortisone/pramoxine. No dietary restrictions necessary.
FDA Pregnancy Category C. First trimester: Insufficient human data; animal studies show teratogenicity at high doses. Second/third trimester: Risk of fetal tachycardia, hypoglycemia, and intrauterine growth restriction due to beta-2 receptor stimulation. Prolonged use may delay labor.
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.
Excreted into breast milk in low amounts; M/P ratio estimated at 0.8 (range 0.5-1.2). Considered compatible with breastfeeding; monitor infant for signs of stimulation (e.g., tachycardia, irritability).
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 routine dose adjustment required. Increased clearance in pregnancy may necessitate higher doses for bronchodilation; monitor clinical response. For tocolysis, use lowest effective dose and limit duration to 48-72 hours due to maternal-fetal risks.
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.
Beta-2 agonists (e.g., albuterol, salmeterol) are primarily used for bronchodilation in asthma and COPD. Short-acting beta-2 agonists (SABAs) are first-line for acute symptoms, while long-acting beta-2 agonists (LABAs) are maintenance therapy, never as monotherapy in asthma. Monitor for hypokalemia and tachycardia. Use with caution in patients with cardiovascular disease, hyperthyroidism, or diabetes. Inhaled route minimizes systemic effects. Overuse indicates poor disease control.
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.
Use only as prescribed; do not increase frequency or dose without consulting your doctor.,Rinse mouth with water after using inhalers containing corticosteroids to prevent thrush.,Seek emergency help if symptoms worsen or if you need more than 2 puffs per week of rescue inhaler.,Know the difference between rescue (blue) and controller (usually brown/purple) inhalers.,Shake inhaler well before use and use proper technique (spacer if needed).,Report palpitations, chest pain, or severe anxiety to your healthcare provider.,Do not stop controller medication suddenly as it may cause worsening of symptoms.
Apply a small amount to the affected area as directed, usually 2-4 times daily.,Do not cover the area with bandages or dressings unless instructed by your doctor.,Avoid use on broken skin, open wounds, or infected areas unless specifically prescribed.,Do not use for more than 2 weeks without medical supervision, especially in the anogenital region.,If symptoms do not improve or worsen, contact your healthcare provider.,Keep away from eyes, mouth, and other mucous membranes.,Wash hands after applying unless treating hands.,Inform your doctor if you are pregnant, planning to become pregnant, or breastfeeding.
