[药动学] Parasympathomimetics
[英文释义] A quarternary ammonium parasympathomimetic agent with the muscarinic actions of ACETYLCHOLINE. It is hydrolysed by ACETYLCHOLINESTERASE at a considerably slower rate than ACETYLCHOLINE and is more resistant to hydrolysis by nonspecific CHOLINESTERASES so that its actions are more prolonged. It is used as a parasympathomimetic bronchoconstrictor agent and as a diagnostic aid for bronchial asthma. (From Martindale,The Extra Pharmacopoeia,30th ed,p1116)
