The patient reports having smoked since age 16 and is currently smoking 1.5 packs/week. She denies drinking alcohol. Past medical history is significant for bouts of untreated essential hypertension. Vital signs reveal blood pressure 165/100 mm Hg. 88 HR, 21 RR. Physical exam reveals pronounced wheezing on lung auscultation. ECG is normal, and CXR shows no lung consolidation. Spirometry reveals low FEV1 & FEV1/FVC. Inhalation of a bronchodilator does not improve FEV1 or FEV1/FVC. Her peak flow meter reading is 110 L/min. The patient’s PCP prescribes Ipratropium bromide (Atrovent®), administered through a metered-dose inhaler. After 1 week of treatment, the patient’s peak flow velocity improves to 220 L/min. Which of the following mechanisms explains the therapeutic effect of Ipratropium bromide in this patient?
