Ipratropium is an anticholinergic drug used in the control of symptoms related to bronchospasm in chronic obstructive pulmonary disease (COPD). It can be found under the brand names Atrovent, Combivent, and Ipravent. It is commonly administered through inhalation which allows producing a local effect without presenting a significant systemic absorption. Ipratropium acts as an antagonist of the muscarinic acetylcholine receptor. 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. 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. Possible side effects of using trospium may include bladder pain, back pain, blurred vision, and dry mouth.
