Got asked last week what would happen if you gave Succinylcholine and then Neostigmine. I answered that the block would be prolonged. I could tell he wanted more than that for an answer, but I really can't seem to find anything at a cellular level anywhere. Tried googling it, no luck. Anyone got any ideas? Thanks

Edited to add: The guy is getting his PhD in Pharmacology, so I'm sure I won't be able to get the entire answer right!
