Pharmacological Management of Chronic Obstructive Pulmonary Disease by Low-Dose Theophylline: A Prospective Hospital-based Study in East Godavari of Andhra Pradesh

Abstract

Background: High therapeutic dose of theophylline is not tolerated well by some patients. As it is an effective and affordable drug, the effectiveness of low-dose theophylline in pharmacological management of chronic obstructive pulmonary disease (COPD) was assessed. Aim: The aim of this study was to detect the efficacy of low-dose theophylline in COPD patients. Patients and Methods: Patients with stable COPD were enrolled. The complete blood picture (CBP), pulmonary function tests (PFTs), and St. George's Respiratory Questionnaire (SGRQ) were performed at enrolment. Patients were categorized into two groups: subjects and controls. All the participants were given medication for COPD as per the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines. However, subjects were kept on low-dose sustained-release oral drug theophylline (150 mg twice daily) as an add-on. At every follow-up, once every 10 days up to 30 days, their parameters were recorded. The difference between the prognostic biomarkers was analyzed using the Student's “t”-test. Results: The CBP, SGRQ, and PFTs showed improvement in COPD patients treated with low-dose theophylline, i.e., subject group. Even though the PFTs improved in subjects, evidence of COPD remained. Low-dose theophylline may help to improve the quality of life in COPD patients. Conclusion: As a Cost-effective medication, low-dose theophylline can be used as an add-on drug to GOLD guidelines for the treatment of COPD. The subjects may feel better and can lead their normal life even with COPD.
