靶点 |
mAChR |
|
体外研究 |
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. |
|
体内研究 |
Oxitropium bromide inhalation shifts force-frequency curves upward at 2h after inhalation and inhibits the decrease of force-frequency curves due to endotoxin injection in vivo.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.Inhalation of the anticholinergic agent oxitropium bromide at doses of 1.5μg and higher greatly attenuates the decrease in mucus score produced by intravenous histamine but not by inhaled histamine. |

动物实验: |
|
|
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=30mm) with a round hole (diameter=10mm) 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. |
