Glycopyrrolate and atropine inhalation: comparative effects on normal airway function
The American Review of Respiratory Disease
|May 1, 1984
Summary
Glycopyrrolate effectively dilates airways for over 6 hours in normal subjects. This bronchodilator provides long-lasting relief without the common side effects associated with atropine inhalation.
Area of Science:
- Pulmonary Medicine
- Pharmacology
Background:
- Inhaled parasympatholytic agents are used for bronchodilation.
- Atropine causes significant side effects like increased heart rate and dry mouth.
Purpose of the Study:
- To compare the bronchodilating effects and side effect profiles of inhaled glycopyrrolate and atropine.
Main Methods:
- Normal subjects inhaled high doses of glycopyrrolate, atropine, or placebo.
- Specific airway conductance (SGaw) and forced expiratory flows were measured.
Main Results:
- Both glycopyrrolate and atropine significantly increased SGaw and expiratory flows.
- Glycopyrrolate's bronchodilating effects lasted longer than 6 hours.
- Atropine caused increased heart rate and dry mouth; glycopyrrolate did not.
Conclusions:
- Inhaled glycopyrrolate provides sustained bronchodilation without the muscarinic side effects of atropine.
- Glycopyrrolate is a promising alternative for long-acting bronchodilation.
