Treatment of MAOI hypertensive crisis with sublingual nifedipine.
How much does nifedipine lower BP?
Continuous hemodynamic monitoring provided further evidence’2 that nifedipine exerts a rapid, profound and persistent antihypertensive action. Mean arterial pressure, in fact, was lowered by 21% of control at 30 minutes (average fall 28 mm Hg) and by 16% at 120 minutes after the drug.
Is nifedipine stronger than hydralazine?
Both nifedipine and hydralazine significantly lowered supine BP from placebo baseline (146 +/- 3/96 +/- 2 mm Hg) to 119 +/- 3/80 +/- 2 and 129 +/- 2/81 +/- 2 mm Hg, respectively. The decrease in systolic BP with nifedipine was significantly lower than that with hydralazine at 9 weeks.
Is nifedipine the same as hydralazine?
Nifedipine is safe and more effective than hydralazine in controlling blood pressure in severe pre-eclampsia. It has the added advantage of being cheaper and more widely available than the latter and is easily administered.
How does MAOI cause hypertensive crisis?
Since MAOIs inhibit monoamine oxidase, they decrease the breakdown of tyramine from ingested food, thus increasing the level of tyramine in the body. Excessive tyramine can elevate blood pressure and cause a hypertensive crisis.
