In Vitro | Oxitropium bromide is a muscarinic antagonist which blocks musucarinic acetylcholine receptors (mAChR). Incubation with oxitropium bromide of untreated diaphragm muscle and diaphragm muscle injected with endotoxin does not increase the force-frequency curves dose-dependently in vitro; however, it causes both types of muscle to be fatigue resistant[1]. |
In Vivo | Oxitropium bromide inhalation shifts force-frequency curves upward at 2 h after inhalation and inhibits the decrease of force-frequency curves due to endotoxin injection in vivo[1]. Oxitropium bromide strongly and persistently inhibits the acetylcholine (ACh)-induced resistance. The increase in resistance induced by histamine, serotonin, leukotriene D4 or antigen is prevented by oxitropium bromide oxitropium bromide[2]. Inhalation of the anticholinergic agent oxitropium bromide at doses of 1.5 μg and higher greatly attenuates the decrease in mucus score produced by intravenous histamine but not by inhaled histamine[3]. |
Animal Admin | Mice: In the oxitropium bromide inhalation group, animals are given 2 puffs of inhalation from a oxitropium bromide MDI (metered dose inhaler) via a 75-mL spacer, and then diaphragm muscles are dissected and measured as to contractility immediately, 1 hour, 2 hours and 4 hours later (n=5 animals each). An animal is placed in a centrifugal tube (inner diameter=30 mm) with a round hole (diameter=10 mm) in the bottom, its nose and mouth being exposed through the hole to breath. An oxitropium bromide MDI (metered dose inhaler) releases 2 puffs into a spacer attached to the tube. Aerosols of oxitropium bromide are inhaled for about 10 seconds, while the animal is breathing spontaneously through the hole of the tube[1]. |
