Can succinylcholine drugs (nicotinic depolarizing neuromuscular blocker) decrease intraocular pressure? Any answers appreciated!

No. Succinylcholine actually causes an increase in intraocular pressure for about 10 minutes after administration. Classic teaching was not to use succ in people with open globe injuries. There are situations, though, where using succ with other agents that lower IOP is preferred because it makes intubation more smooth, avoiding hypertension and airway reactivity that is worse for the situation anyway.

Is it possible that succinylcholine drugs (nicotinic depolarizing neuromuscular blocker) decrease intraocular pressure?

No. Succinylcholine is known to increase intraocular minimally when given to secure the airway. The increase is small and passing, therefore it has been used in patients with increased intraocular pressure. Read more...
