Respiration; International Review of Thoracic Diseases
|January 1, 1981
Summary
Tiaramide hydrochloride (THC) effectively improved lung function in patients with chronic obstructive lung disease. This bronchodilator demonstrated a sustained effect, indicating a clinical advantage for COPD management.
Area of Science:
- Pulmonology
- Pharmacology
Background:
- Chronic obstructive lung disease (COPD) is a progressive respiratory condition characterized by airflow limitation.
- Effective bronchodilator therapy is crucial for managing COPD symptoms and improving quality of life.
Purpose of the Study:
- To evaluate the efficacy and safety of tiaramide hydrochloride (THC) as a bronchodilator in non-asthmatic patients with COPD.
- To assess the duration and clinical significance of the bronchodilator effect of THC.
Main Methods:
- A double-blind, cross-over bioassay was conducted involving 32 non-asthmatic COPD patients.
- Patients received a single administration of tiaramide hydrochloride (200 mg) and placebo.
- Pulmonary function tests including FVC, FEV1, FM25-75, PEF, and FEF200-1,200 were measured pre- and post-treatment up to 360 minutes.
Main Results:
- Significant differences in pulmonary function were observed between tiaramide hydrochloride and placebo.
- Tiaramide hydrochloride demonstrated a notable bronchodilator effect.
- No significant adverse variations were reported with placebo administration.
Conclusions:
- Tiaramide hydrochloride (THC) is an effective and safe bronchodilator for patients with COPD.
- The sustained bronchodilator effect of THC presents a potential clinical advantage in COPD management.
