question about drugs used for intubation

Why is succinylcholine preferred over roscuronium for intubation? I mean, besides havings a shorter duration of action for succinylcholine, I don't seen succ's having any other advantage. It seems like roscuronium would be safter because it can be easily reversed with neostigmine, so less issues of side effects... Is this correct? I'm only a second year medical student studying for a cummulative pharmacology exam, and am just curious.

I wouldn't say that sux is "preferred" - I intubate with roc more often than sux.

Sux has faster onset, which in some scenarios is important.

Roc, at intubating doses, is not going to be immediately reversible with neostigmine. Basically, it has to wear off a little bit before using neostigmine will produce full reversal of paralysis.

Until the FDA changes its mind about sugammadex, sux isn't going anywhere.
