What is an adverse sign of taking Procardia?

The correct answer highlights reflex tachycardia as an adverse sign of taking Procardia, which is a calcium channel blocker primarily used for the treatment of hypertension and angina. Procardia can lead to a relaxation of vascular smooth muscle, resulting in vasodilation. This vasodilation lowers systemic blood pressure, and the body may respond with reflex tachycardia to compensate for the decreased blood pressure. The heart rate increases to maintain adequate cardiac output and blood flow to vital organs.

It’s essential to recognize reflex tachycardia as a notable response because it may counteract the intended therapeutic effects of the medication and can lead to further cardiovascular complications if not monitored properly.

In contrast, while peripheral edema is a common side effect of calcium channel blockers like Procardia, it is not typically classified as an acute adverse sign in the same manner as reflex tachycardia. Increased blood pressure would not be an expected effect from a medication designed to lower it, and reflex bradycardia, while possible, is less commonly associated with calcium channel blockers than reflex tachycardia. Thus, understanding the mechanisms and expected physiological responses can help in recognizing and managing potential adverse effects in patients taking Procardia.
