THEOLAIR vs TORNALATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Beta-2 adrenergic receptor agonist; relaxes bronchial smooth muscle by increasing cyclic AMP.
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.
2 puffs (340 mcg) inhaled via oral inhalation 4 times daily; maximum 12 puffs/day.

Adults: 3-8 hours (mean 5.5); children: 1.5-5 hours; increased in hepatic cirrhosis, heart failure, and COPD; decreased in smokers
Terminal elimination half-life is approximately 9-12 hours in healthy adults. May be prolonged in elderly or those with hepatic impairment, necessitating dose adjustment.
Renal (10% unchanged); hepatic metabolism (90%) with metabolites excreted in urine
Primarily renal excretion of unchanged drug and metabolites; <10% fecal. Approximately 60-70% of a dose is recovered in urine as unchanged drug and glucuronide conjugates within 24 hours.
