Few reasons: It's a vasodilator (dilates blood vessels) and has a couple of common uses

1: it can be used for high blood pressure, although usually not a first choice these days since its dosed frequently when given in pill form.

Question 3

hydralazine side effects?

Accepted Answer

Fatigue, see below: Most side effects are rare, but of the ones that patients are more likely to experience with this med, fatigue/tiredness, diarrhea, and upset stomach are more common. It rarely, and i mean rarely, can cause symptoms similar to systemic lupus erythematosis (sle or lupus). This drug induced lupus is reversible when the med is stopped. I think Labetalol during pregnancy is a better option.

how does hydralazine block the vagus nerve?

Accepted Answer

Not a MOA: Hydralazine is a direct smooth muscle relaxer based on its intracellular action on Calcium.  In situ, it does not appear to have a direct effect on the vagus nerve, but rather may have an effect on the sinoatrial node and a reflex response (increased heart rate) due to the decreased blood pressure (baroreceptor response).
