BRONKAID MIST vs THEOVENT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Epinephrine, the active ingredient, is a direct-acting sympathomimetic amine that stimulates alpha- and beta-adrenergic receptors. Beta-2 receptor activation in bronchial smooth muscle causes bronchodilation. Alpha receptor activation causes vasoconstriction, reducing mucosal edema.
Theovent is a brand name for theophylline, a xanthine derivative that acts as a bronchodilator by inhibiting phosphodiesterase, leading to increased intracellular cAMP levels, and by antagonizing adenosine receptors.
2 inhalations (200 mcg per inhalation) every 4 hours as needed for bronchospasm. Maximum 12 inhalations in 24 hours.
Oral: 200-400 mg every 12 hours; maximum 800 mg/day. Intravenous: 200 mg loading dose over 30 minutes, then 200 mg every 12 hours.

Terminal elimination half-life: 3-6 hours; clinical context: shorter half-life in children, prolonged in hepatic impairment; requires frequent dosing
Terminal elimination half-life 7-9 hours, prolonged in patients with hepatic impairment (up to 12 hours) or heart failure.
Renal: 40-70% unchanged; fecal: minor (biliary) <5%
Renal (70% as unchanged drug), biliary/fecal (30% as metabolites).
