BRONITIN MIST vs THEOLAIR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BRONITIN MIST contains isoproterenol, a non-selective beta-adrenergic agonist that stimulates beta-1 and beta-2 receptors, leading to bronchodilation via relaxation of bronchial smooth muscle, increased heart rate, and increased contractility.
Theophylline, the active ingredient in THEOLAIR, is a phosphodiesterase inhibitor that increases intracellular cAMP levels, leading to bronchodilation via smooth muscle relaxation. It also has anti-inflammatory effects and may enhance diaphragmatic contractility.
For acute bronchospasm: 1-2 inhalations (0.1 mg per inhalation) via aerosol inhaler every 4-6 hours as needed.
Initial dose: 300 mg orally every 8-12 hours; titrate based on serum theophylline levels to achieve 5-15 mcg/mL. Maintenance: 400-600 mg/day in divided doses.

Terminal elimination half-life is 3-4 hours in adults; may be prolonged in hepatic or renal impairment, requiring dose adjustment.
Adults: 3-8 hours (mean 5.5); children: 1.5-5 hours; increased in hepatic cirrhosis, heart failure, and COPD; decreased in smokers
Primarily renal (approximately 70-80% as unchanged drug and metabolites); biliary/fecal excretion accounts for 20-30%.
Renal (10% unchanged); hepatic metabolism (90%) with metabolites excreted in urine
