Application

Ipratropium bromide monohydrate has been used for the inhibition of peripheral muscarinic receptors in rats.

Biochem/physiol Actions

Ipratropium bromide monohydrate is a nonselective muscarinic acetylcholine receptor antagonist and a bronchodilator. In nebulized form, it is used for treating asthma and obstructive pulmonary diseases. It acts as a β2 adrenoreceptor agonist. Ipratropium bromide monohydrate is an anticholinergic agent and competes with acetylcholine. It promotes bronchodilation by stimulating sympathetic pathways.

Tiotropium is a long-acting anticholinergic drug. Studies with cloned human muscarinic receptors show that tiotropium binds equally well to M(1), M(2), and M(3) receptors. However, it dissociates very slowly from M(1) and M(3) receptors compared with ipratropium, and more rapidly
For COPD a combination of ipratropium bromide and albuterol sulfate is more effective than albuterol base.

1. In this study we have evaluated the pharmacological profile of the muscarinic antagonist glycopyrrolate in guinea-pig and human airways in comparison with the commonly used antagonist ipratropium bromide. 2. Glycopyrrolate and ipratropium bromide inhibited EFS-induced contraction of guinea-pig trachea

Two major groups of drugs are available to prevent bronchoconstriction: beta-agonists and muscarinic blocking agents. Ipratropium is the most commonly used anticholinergic agent to treat chronic obstructive pulmonary disease. The authors studied anti-muscarinic agents to determine if they are as
