Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
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.
Noxivent is a synthetic analog of epinephrine that acts as a non-selective alpha and beta adrenergic receptor agonist. It binds to alpha-1 receptors causing vasoconstriction, alpha-2 receptors reducing insulin secretion, beta-1 receptors increasing heart rate and contractility, and beta-2 receptors causing bronchodilation and vasodilation. Its primary effect in septic shock is increasing mean arterial pressure via vasoconstriction.
FDA-approved for the treatment of eczematous dermatitis, atopic dermatitis, and other glucocorticoid-responsive dermatoses complicated by fungal or bacterial infections
Increase blood pressure in adults with septic shock who remain hypotensive despite adequate fluid resuscitation and treatment with vasopressors (e.g., norepinephrine) and inotropes (e.g., dobutamine) to maintain mean arterial pressure ≥65 mm Hg
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.
700 mg orally twice daily with food.
1.5-2 hours (terminal) after intravenous administration; prolonged in hepatic impairment.
Terminal elimination half-life 4-6 hours; prolonged in renal impairment (up to 12 hours) requiring dose adjustment.
Hydrocortisone is primarily hepatic via CYP3A4; iodoquinol is not extensively metabolized, with partial glucuronidation and enterohepatic circulation.
Primarily metabolized by monoamine oxidase (MAO) and catechol-O-methyltransferase (COMT) in the liver and other tissues. Also undergoes oxidation and conjugation.
Renal (primarily as metabolites; <5% unchanged); fecal (biliary excretion of metabolites).
Primarily renal (70-80% unchanged), with 10-15% biliary/fecal. Minor metabolism via ester hydrolysis.
90-95% (albumin and corticosteroid-binding globulin).
85-90% bound to albumin; reduced binding in hypoalbuminemia.
0.4-0.6 L/kg; indicates distribution into total body water and tissues.
0.8-1.2 L/kg; suggests extensive tissue distribution (e.g., lung, liver).
Oral: 80-90%; Intramuscular: 100%; Intravenous: 100%.
Oral: 50-60% (first-pass metabolism); Sublingual: 70-80%; No data for other routes.
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.
GFR 30-59 m L/min: 350 mg twice daily; GFR <30 m L/min or on dialysis: 350 mg once daily.
No specific adjustment for topical use. In Child-Pugh C cirrhosis, consider the risk of systemic corticosteroid accumulation; use with caution.
Child-Pugh A: no adjustment; Child-Pugh B: 350 mg twice daily; Child-Pugh C: not recommended.
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.
Not approved for pediatric use.
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 specific dose adjustment; monitor renal function and use lowest effective dose.
None
None.
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.
May cause severe hypertension, cardiac arrhythmias (especially with pre-existing conditions), tissue ischemia due to vasoconstriction, and exacerbation of heart failure. Use with caution in patients with hyperthyroidism, diabetes (as it increases blood glucose), and history of coronary artery disease.
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).
Hypersensitivity to noxivent or any component; uncontrolled hypertension; tachyarrhythmias; ventricular fibrillation; use with non-selective MAO inhibitors (risk of hypertensive crisis).
No clinically significant food interactions are reported for topical hydrocortisone/pramoxine. No dietary restrictions necessary.
No specific food interactions reported. Grapefruit juice may increase formoterol levels (avoid if possible). Take with or without food.
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.
NOXIVENT is a combination of a long-acting beta-agonist (LABA) and an inhaled corticosteroid (ICS). Inhaled beta-agonists have low systemic bioavailability and are generally considered low risk in pregnancy. Studies with inhaled corticosteroids (budesonide, fluticasone) show no increased risk of major malformations. First-trimester exposure data for LABAs are limited but do not indicate a significant teratogenic risk. However, high-dose systemic corticosteroids are associated with cleft palate. Inhaled doses minimize systemic exposure. Overall, NOXIVENT is considered safe for use in pregnancy when asthma control is necessary.
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 on NOXIVENT specific M/P ratio. Both components (beta-agonist and corticosteroid) are excreted in human milk in small amounts, but are unlikely to affect the infant due to low oral bioavailability. Inhaled doses result in minimal systemic concentrations. The American Academy of Pediatrics considers inhaled beta-agonists and corticosteroids compatible with breastfeeding. Use with caution, especially with high doses.
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 dose adjustment required for NOXIVENT based on pharmacokinetic changes in pregnancy. Asthma management guidelines recommend using standard doses to maintain control. However, pregnancy may alter asthma severity; dose titration is based on symptom control rather than pharmacokinetic adjustment. Consider step-down if asthma improves, step-up if worsens. Monitor for systemic effects of high doses (e.g., growth restriction from ICS).
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.
NOXIVENT (formoterol + glycopyrrolate) is a fixed-dose LABA/LAMA combination for COPD. Avoid use in asthma due to increased risk of asthma-related death. Monitor for paradoxical bronchospasm; discontinue immediately if occurs. Assess renal function before initiating glycopyrrolate (primarily renally excreted). Not for acute bronchospasm relief.
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.
Use exactly as prescribed; do not exceed recommended dose or frequency.,This medication is for maintenance treatment of COPD, not for acute symptoms. Always have a rescue inhaler (e.g., albuterol) available.,Rinse mouth with water after each dose to prevent thrush (oral candidiasis).,Report worsening breathing, chest tightness, or signs of allergic reaction (rash, hives, swelling) immediately.,Do not stop using NOXIVENT without consulting your doctor, even if you feel better.
