Labatelol: |
Mixed a & b-blocker |
|
|
|
IVP DOSING |
| 10-20 mg |
Slow IVP over 2 minutes. Repeat as needed. I like this drug, because it works really well (usually)! Like Hydralazine, if your order says Q4 hours PRN, it probably will not be enough during a 12 hour shift. You need to keep giving it to your patient until you get the pressure down! |
| (or 0.25mg/kg) | |
|
300 mg |
MAX dose. |
|
INFUSION DOSING |
|
Obviously, if you haven't given a bolus, its going to be at least 5-10 minutes before you see results. |
1-4 mg/min |
Primarily
used for acute, severe HTN, Labetalol causes less vasoconstriction and less
bronchospasm than Propranolol does, and, it works better than Propranolol in
black patients, and has a more rapid effect on BP (keep patient supine
during IV administration).
