BRONITIN MIST vs THEOLAIR-SR
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 is a methylxanthine that relaxes bronchial smooth muscle by inhibiting phosphodiesterase, increasing cAMP, and antagonizing adenosine receptors.
For acute bronchospasm: 1-2 inhalations (0.1 mg per inhalation) via aerosol inhaler every 4-6 hours as needed.
Oral: 300-600 mg every 12 hours; sustained-release formulation; adjust based on serum theophylline concentrations (target 5-15 mcg/mL).

Terminal elimination half-life is 3-4 hours in adults; may be prolonged in hepatic or renal impairment, requiring dose adjustment.
Adults: 8 hours (range 5-12). Children: 3.5 hours (range 1-8). Smokers: 4-5 hours. Congestive heart failure/hepatic cirrhosis: >24 hours.
Primarily renal (approximately 70-80% as unchanged drug and metabolites); biliary/fecal excretion accounts for 20-30%.
Renal (10% unchanged) and hepatic metabolism (90%). Metabolites excreted in urine.
