BRONKOMETER vs THEOBID JR.
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Beta-2 adrenergic receptor agonist; relaxes bronchial smooth muscle by increasing cyclic AMP.
Inhibits phosphodiesterase, increasing intracellular cAMP; causes bronchodilation, central nervous system stimulation, and positive inotropic/chronotropic effects.
Isoetharine mesylate 0.5% solution: 2-4 inhalations every 4 hours as needed via hand-held nebulizer or IPPB.
300 mg orally every 12 hours, extended-release tablet. Titrate to serum theophylline concentration of 5-15 mcg/mL.

Terminal elimination half-life: 2-3 hours; clinically, bronchodilation persists but dosing interval is 3-4 hours due to rapid onset and offset.
3-8 hours in adults; prolonged in neonates, cirrhosis, heart failure (up to 30 hours). Tobacco smoking induces clearance (half-life 4-5 hours).
Renal: 10-15% unchanged; 70-80% as sulfate conjugates; biliary/fecal: <5%.
Hepatic metabolism (90%), renal excretion of unchanged drug (10%). Metabolites excreted in urine.
