Název v původním jazyce
Characterization of the anticholinergic properties of obidoxime; functional examinations of the rat atria and the urinary bladder
Popis výsledku v původním jazyce
Obidoxime, a well-known bis-pyridinium reactivator, is often the preferred antidote of organophosphorus poisoning caused by pesticides and tabun. It is also considered to be an allosteric modulator of muscarinic receptors, preferably M2 sub-type. This study compared the effect of obidoxime and atropine in vivo and in vitro on the cholinergic stimulation of the rat heart (M2) and the urinary bladder (M3). The results showed that obidoxime exerts anti-muscarinic effects, that may play an important role inthe treatment of organophosphourus poisoning, and that the muscarinic receptor inhibition profile shows M2 receptor selectivity. This anti-muscarinic effect is much smaller that the effect of atropine and might be due to the allosteric inhibition of thereceptors. The results also indicate that the acetylcholinesterase inhibition and the muscarinic receptor antagonism occur at different concentrations and dose levels.
