Do selective adeno-adenergic blockers (prazosin, terazosin, doxazosin, trimazosin) protect from acute cocaine-induced vasoconstrictive damage?
Some: Cocaine causes it's effect by preventing the reuptake of monamine (epinephrine, etc) and causes these neurotransmitters to continue exciting the a1 receptor. The meds listed block alpha-1 receptors, so theoretically will blunt the effects of Cocaine on some vessels, but focus mostly (esp. Tamsulosin) on a specific sub-type (alpha-1a) that is mostly in the bladder, not in the vessels. ...Read moreSee 1 more doctor answer

No other form: Presently, there is no other form of Dobutamine on the market. Generally, when Dobutamine is used, one is seeking immediate action of the drug, if the drug was administered through just about any other route, it would take longer to act and the delay in action is not desirable.

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 ...Read moreSee 1 more doctor answer
