Atrovent

Ipratropium bromide is a type of anticholinergic medication used to treat respiratory conditions such as chronic obstructive pulmonary disease (COPD) and asthma, as well as rhinorrhea (runny nose) caused by allergic rhinitis, nonallergic rhinitis, and the common cold. It is available in inhaler, nebulizer, and nasal spray forms, and works by causing smooth muscles to relax, which opens up airways and reduces fluid production in the nose. Common side effects include dry mouth, cough, and shortness of breath, while potentially serious side effects include urinary retention and severe allergic reactions. Ipratropium bromide is considered safe during pregnancy and breastfeeding, but may pass into breast milk and harm a nursing baby. It was patented in 1966 and approved for medical use in 1974, and is available as a generic medication.learn more on wikipedia
