Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
The combination product contains a corticosteroid (dexamethasone) which suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis, and a topical antibiotic (usually neomycin or polymyxin B) which inhibits bacterial protein synthesis or disrupts bacterial cell membranes.
Beta-2 adrenergic receptor agonist; stimulates adenyl cyclase, increasing cyclic AMP, leading to bronchodilation.

2 puffs (100 mcg each) intranasally twice daily
Subcutaneous: 0.25-0.5 mg every 1-2 hours as needed; Intravenous: 0.25-0.5 mg over 1 minute, may repeat every 1-2 hours; Inhalation (metered-dose inhaler): 2 inhalations (0.4 mg) every 6 hours; Nebulized: 2.5-5 mg every 6-8 hours.
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).
3-4 hours (terminal); prolonged in renal impairment (up to 8-10 hours) and in elderly patients.
Dexamethasone is metabolized primarily in the liver via CYP3A4; topical antibiotics (neomycin, polymyxin B) are minimally absorbed and not significantly metabolized.
Metabolized in the liver via sulfonation (sulfotransferase enzymes) and to a minor extent by catechol-O-methyltransferase (COMT).
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 (60-70% as unchanged drug and metabolites); fecal elimination accounts for a minor fraction (<5%).
Approximately 85% bound to serum albumin and alpha-1-acid glycoprotein.
Approximately 25% bound to albumin.
Vd is 3-4 L/kg, indicating extensive tissue distribution with accumulation in liver and kidneys.
~0.6 L/kg; indicates distribution into total body water.
Oral: 40-50% due to first-pass metabolism; Topical: 5-10% systemically; IV: 100%.
Inhalation: ~10-20% (dependent on device and technique); Oral: ~15-20% (due to extensive first-pass metabolism).
No adjustment required for any GFR level
No specific dose adjustment recommended for renal impairment; use with caution in severe renal impairment (e GFR <30 m L/min/1.73 m²) due to potential for increased systemic exposure.
Child-Pugh Class A: no adjustment; Child-Pugh Class B/C: no data available; use with caution
No specific dose adjustment recommended; caution in severe hepatic impairment (Child-Pugh Class C) due to reduced clearance.
Children 6-11 years: 1 puff (50 mcg) per nostril twice daily; Children ≥12 years: same as adult
Subcutaneous: 5-10 mcg/kg every 1-2 hours as needed (max 0.5 mg); Intravenous: 5-10 mcg/kg over 1 minute (max 0.5 mg); Inhalation (MDI): 1-2 inhalations (0.2-0.4 mg) every 4-6 hours; Nebulized: 0.01-0.03 mg/kg (max 1 mg) every 6-8 hours.
No specific dose adjustment; monitor for adrenal suppression and osteoporosis risk with prolonged use
Initiate at lower end of dosing range (e.g., subcutaneous 0.125 mg); monitor for tachycardia, hypertension, and tremor; consider age-related decline in renal and hepatic function.
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.

No specific food interactions. Avoid grapefruit juice as it may increase systemic exposure to ciclesonide via CYP3A4 inhibition.
No significant food interactions. However, avoid excessive caffeine intake (coffee, tea, cola) as it may exacerbate beta-agonist side effects like palpitations and tremor.
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.
Insufficient human data; animal studies show no evidence of teratogenicity at clinically relevant doses. Risk cannot be excluded; use only if clearly needed. First trimester: limited data suggest no major malformations. Second and third trimesters: may cause fetal tachycardia, hypoglycemia, and transient hypocalcemia. Avoid in preterm labor due to maternal and fetal adverse effects.
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.
Excreted into breast milk in small amounts; M/P ratio approximately 2.5. No adverse effects reported in infants at therapeutic maternal doses. However, monitor infant for signs of beta-2 adrenergic stimulation (e.g., tachycardia, irritability). Consider risk-benefit.
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 specific dose adjustments recommended for asthma or COPD. However, in preterm labor (off-label), use lowest effective dose and shortest duration due to increased risk of maternal pulmonary edema, cardiac ischemia, and fetal effects. Monitor closely.
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.
BRICANYL (terbutaline sulfate) is a beta-2 adrenergic agonist used for bronchodilation in asthma and COPD. It can cause transient hypokalemia, hyperglycemia, and tremor. Use with caution in patients with diabetes, hypertension, or hyperthyroidism. Monitor serum potassium in patients on diuretics or with hypoxia. Not recommended for acute severe asthma as monotherapy; prefer short-acting beta-agonists like albuterol.
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.
Use exactly as prescribed; do not increase dose or frequency without consulting your doctor.,Shake the inhaler well before each use.,Rinse mouth with water after inhalation to prevent oral thrush.,Seek emergency medical help if breathing problems worsen or if you have chest pain or irregular heartbeat.,Monitor blood sugar if diabetic as this medication may raise blood glucose levels.,Avoid caffeine as it may increase side effects like nervousness and rapid heart rate.
