Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Theophylline competitively inhibits phosphodiesterase, increasing cAMP levels, and acts as an adenosine receptor antagonist, leading to bronchodilation and reduced airway inflammation.
Selective beta-2 adrenergic receptor agonist; relaxes bronchial smooth muscle by increasing intracellular cyclic AMP via activation of adenylyl cyclase.
For asthma and COPD: 1-2 inhalations (90 mcg each) via metered-dose inhaler, 2 puffs twice daily, maximum 4 puffs twice daily. For acute exacerbations: 4-8 puffs every 20 minutes for up to 4 hours, then every 1-4 hours as needed.
2 inhalations (90 mcg each) every 4-6 hours as needed via oral inhalation. Maximum 12 inhalations per 24 hours.
