    Area of Science:

    • Pulmonary Medicine
    • Pharmacology

    Context:

    • Investigating long-term therapeutic effects on respiratory conditions.
    • Assessing the efficacy of slow-release theophylline formulations.

    Purpose:

    • To evaluate the impact of sustained-release theophylline on FEV1 and PEF.
    • To determine the contribution of the galenic formulation to therapeutic outcomes.

    Summary:

    • A multicenter study involving 908 patients demonstrated that slow-release theophylline improved FEV1 and PEF.
    • Asthma patients saw approximately 20% improvement, while COPD patients experienced 11-14% increases.
    • The specific slow-release formulation enhanced theophylline's therapeutic benefits.

    Impact:

    • Provides evidence for the efficacy of slow-release theophylline in managing asthma and COPD.
    • Highlights the importance of formulation in drug delivery and patient outcomes.
    • Supports the use of optimized theophylline preparations for improved pulmonary function.
