In some situations, reactivation of inhibited AChE by oximes is likely to be absent or limited when affinity for the particular OP-AChE complex is poor, the dose or duration of treatment is insufficient, the OP persists in the patient and therefore rapid reinhibition of the newly reactivated enzyme occurs, and the inhibited AChE ages.
