Bronchitis Clinical Trial
Official title:
Outcome Study to Evaluate the Role of Klaricid XL (Clarithromycin Modified Release) in the Treatment of Acute Exacerbation of Chronic Bronchitis (AECB) and Its Impact on Quality of Life Measured by St. George's Respiratory Questionnaire (SGRQ)
The objective of this study was to evaluate the role of Klaricid XL (clarithromycin modified release) in the treatment of acute exacerbation of chronic bronchitis (AECB) and its impact on improving the quality of life.
Participants in this observational study had a diagnosis of chronic bronchitis and signs and
symptoms of an acute exacerbation, clinically diagnosed by the sudden worsening of symptoms
characterized by extreme breathlessness and increased chest tightness, wheezing, cough, or
sputum changes. A sequential non-systematic sample of patients with AECB from May 2011 until
January 04, 2012 is included in this observational study.
The observation period for each individual patient started with the diagnosis of the acute
exacerbation of chronic bronchitis and prescription of antimicrobial medication per routine
clinical care. This observational period continued during the treatment period and ended on
at least one follow-up visit at the end of the treatment. Duration of treatment was based on
physician's judgment of severity of the patient's condition. The usual treatment period
ranges from 5 to 14 days.
