Relief of inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses (e.g., psoriasis, eczema, contact dermatitis)
2 puffs (100 mcg each) intranasally twice daily
Topical: Apply a thin film to affected skin areas twice daily. Maximum 60 g per week. Use for no longer than 2 consecutive weeks.
Terminal elimination half-life is 12-15 hours in adults with normal renal function; prolonged to 24-30 hours in severe renal impairment (Cr Cl <30 m L/min).
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.
Dexamethasone is metabolized primarily in the liver via CYP3A4; topical antibiotics (neomycin, polymyxin B) are minimally absorbed and not significantly metabolized.
Primarily hepatic metabolism via CYP3A4; metabolites are excreted renally.
Renal elimination of unchanged drug accounts for 30-40% of the dose; fecal/biliary elimination is 50-60% as metabolites. Less than 10% is excreted unchanged in feces.
Primarily renal; <5% fecal. About 40% of a dose is excreted in urine as unchanged drug and glucuronide conjugates.
Approximately 85% bound to serum albumin and alpha-1-acid glycoprotein.
Approximately 95–99% bound to plasma proteins, primarily albumin and corticosteroid-binding globulin.
Vd is 3-4 L/kg, indicating extensive tissue distribution with accumulation in liver and kidneys.
Apparent volume of distribution is about 0.14–0.3 L/kg, indicating extensive tissue distribution.
Oral: 40-50% due to first-pass metabolism; Topical: 5-10% systemically; IV: 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 any GFR level
No adjustment required for topical use. Systemic absorption is minimal.
Child-Pugh Class A: no adjustment; Child-Pugh Class B/C: no data available; use with caution
No adjustment required for topical use. Systemic absorption is minimal.
Children 6-11 years: 1 puff (50 mcg) per nostril twice daily; Children ≥12 years: same as adult
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.
No specific dose adjustment; monitor for adrenal suppression and osteoporosis risk with prolonged use
Use lowest effective dose for shortest duration. Apply sparingly due to thinner skin and increased systemic absorption risk. Avoid use on large areas or under occlusive dressings.
Prolonged use may result in glaucoma with damage to the optic nerve, defects in visual acuity and fields of vision, and posterior subcapsular cataract formation. Prolonged use may suppress the host response and thus increase the hazard of secondary ocular infections. In those diseases causing thinning of the cornea or sclera, perforations have been known to occur with the use of topical steroids.
None.
Prolonged use may lead to ocular hypertension/glaucoma,Posterior subcapsular cataract formation,Delayed wound healing,Secondary ocular infections (including fungal infections),Corneal/scleral thinning and perforation,Systemic absorption with prolonged use (especially in children),Avoid use in patients with known hypersensitivity to any component
Systemic absorption with prolonged use or large areas may cause HPA axis suppression, Cushing's syndrome, or hyperglycemia.,Local adverse reactions include skin atrophy, striae, telangiectasias, and secondary infections.,Avoid use on face, axillae, or groin unless directed; use caution in patients with impaired skin integrity.,Not recommended for diaper dermatitis or for use under occlusive dressings.
Epithelial herpes simplex keratitis (dendritic keratitis),Vaccinia, varicella, and other viral infections of the cornea and conjunctiva,Mycobacterial infections of the eye,Fungal diseases of ocular structures,Hypersensitivity to any component of the formulation
Hypersensitivity to amcinonide or any component of the formulation.,Untreated bacterial, viral, or fungal infections at the application site.,Topical application for ophthalmic or intravaginal use.
No specific food interactions. Avoid grapefruit juice as it may increase systemic exposure to ciclesonide via CYP3A4 inhibition.
No known food interactions. Avoid excessive ingestion of corticosteroids systemically, but topical application does not require dietary restrictions.
Pregnancy Category C. First trimester: potential for teratogenicity based on animal studies; avoid unless benefit outweighs risk. Second/third trimester: drug may cause fetal harm due to pharmacological effects; use only if clearly needed.
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.
Excreted in human milk in unknown amounts; M/P ratio not established. Caution advised due to potential for serious adverse reactions in nursing infants; discontinue drug or nursing depending on importance to mother.
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 established dose adjustments in pregnancy; pharmacokinetics may be altered due to increased plasma volume and metabolism. Use lowest effective dose; individualize therapy based on clinical response.
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-DEX is a fixed-dose combination of an inhaled corticosteroid (ciclesonide) and a long-acting beta-agonist (formoterol). Use as maintenance therapy for asthma, not for acute bronchospasm. Rinse mouth after inhalation to prevent oral candidiasis. Monitor for adrenal suppression with prolonged use. Dose formoterol component at low to moderate doses to minimize risk of asthma-related death.
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.
Use regularly as prescribed, not for sudden breathing problems.,Rinse mouth with water after each use to prevent thrush.,Do not stop suddenly; taper under doctor guidance.,Seek emergency if rescue inhaler not effective.,Report worsening asthma, chest pain, or signs of steroid excess.
Apply a thin layer to affected skin only; do not use on broken or infected skin unless prescribed.,Wash hands after application unless treating hands.,Do not cover treated area with bandages or plastic wrap unless instructed by your doctor.,Avoid contact with eyes, mouth, and mucous membranes.,Do not use for longer than prescribed; overuse can lead to skin thinning and other side effects.,Inform your doctor if you are pregnant, breastfeeding, or planning to become pregnant.
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."
