Study Arms (2)

magnesium sulfate

ACTIVE COMPARATOR

intravenous infusion of magnesium sulfate at a dose of 4 gm intravenously over 20 min as a loading dose then MgSO4 intravenous infusion is continued at a rate of 1 gm/h for 24 h or until obtain and stabilize the targeted blood pressure..

Drug: Magnesium sulfate

labetolol

ACTIVE COMPARATOR

The patients will be given intravenous infusion of labetolol (Trandate™, 5mg/ml) available in 20 ml ampoules containing 100mg labetalol (5mg/ml). Starting the infusion with 20mg/h and then titrate to obtain and stabilize the targeted blood pressure by adjusting the infusion as required every 15 - 30min to a maximum dose of 160mg/hr.

Drug: Labetolol

Interventions

Also known as: (Trandate™,)
