Aim:
To compare oral nifedipine and intravenous labetalol in the treatment of acute severe hypertension in pregnancy (SHP).
Methods:
The primary outcomes were the required time to achieve target blood pressure (RTATBP), systolic blood pressure (SBP) and diastolic BP (DBP) after treatment, secondary outcomes were the number of doses (NoD) and adverse events (AEs).
Results:
There was no difference between oral nifedipine and intravenous labetalol in SBP, DBP, and AE. However, oral nifedipine provided less RTATBP and NoD.
Conclusion:
Oral nifedipine was associated with less RTATBP and NoD and otherwise did not differ from intravenous labetalol.

Antianginal Drugs: Nitrates and β-Blockers
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....
