What is Ipratropium for?

Ipratropium belongs to a class of medications called anticholinergics. It can widen the airway by relaxing the airway muscles. It also inhibits nasal secretions when used nasally. It is commonly used for asthma, chronic obstructive pulmonary disease (COPD), runny nose, post-nasal drip, and rhinitis.

How to use it?

Ipratropium is available in the form of an inhaler or a nasal spray. The inhaler form of Ipratropium is usually used for asthma relief, while a nasal spray is used for the relief of rhinitis and runny nose. A nebulised solution will be used for people who cannot use the ordinary inhaler.
