Ipratropium Bromide (as monohydrate), Fenoterol HBr

Indications

Ipratropium Bromide (as monohydrate), Fenoterol HBr is used for: Ipratropium
Inhaled ipratropium is indicated in combination with inhaled beta-agonist systemic corticosteroids for the management of severe exacerbations of asthma flares requiring treatment.[A176939] Asthma exacerbations are characterized by a progressive increase in one or more of asthma symptoms accompanied by a decrease in expiratory flow.[L5900] As a single agent, ipratropium was indicated for the symptomatic relief of rhinorrhea associated with the common cold or seasonal allergic rhinitis for patients 5 years or older. It does not alleviate nasal congestion nor sneezing.[FDA label] Rhinorrhea refers to recurrent or chronic watery nasal discharge. This condition is debilitating and its pathogenesis and etiology is complex and not very well understood presenting very substantial cost burden.[L5903] Additionally, ipratropium is indicated as a bronchodilator for maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease including chronic bronchitis and emphysema.[FDA label] The chronic obstructive pulmonary disease includes a large number of conditions characterized by breathlessness. As this includes several conditions, the etiology, symptoms, and treatments are diverse.[L5906] Ipratropium has also been studied to be used for the treatment of sialorrhea.[A176942] Sialorrhea is a common symptom that accompanies different neurologic conditions and it is characterized by drooling or excessive salivation.[A176963]

Mechanism of Action

Ipratropium
Ipratropium acts as an antagonist of the muscarinic acetylcholine receptor.[A176939] This effect produces the inhibition of the parasympathetic nervous system in the airways and hence, inhibit their function. The function of the parasympathetic system in the airway is to generate bronchial secretions and constriction and hence, the inhibition of this action can lead to bronchodilation and fewer secretions.[A176945] At the cellular level, the diameter of the airways is controlled by the release of acetylcholine into the muscle cells causing them to contract and producing a narrow airway. Thus administration of ipratropium stops the activity of acetylcholine in the smooth muscle preventing the contraction and producing relaxed airways.[T457]
Fenoterol
Beta(2)-receptor stimulation in the lung causes relaxation of bronchial smooth muscle, bronchodilation, and increased bronchial airflow.
