Vasopressors are not the same as vasoconstrictors![edit]

I killed the link between "pressors" and "vasoconstrictors" because it will be misleading to novices.

Most 'pressors' (drugs which increase the blood pressure) act via multiple mechanisms, including improving cardiac contractility and vasoconstriction. Some (dopamine, epinephrine) have dose-dependent effects.

Many vasoconstrictors are poor ionotropes (e.g. PE, which becomes really clear when you have someone on a non-selective beta-blocker).

Let's not put vasoconstrictors with vasopressors in the same bucket. — Preceding unsigned comment added by DrKC MD (talkcontribs) 00:16, 7 January 2012 (UTC)
