Which is NOT a blood pressure reducer?

• A. Enalapril
• B. Mirataz
• C. Benazepril
• D. Prazosin

Answer: (B)

The key idea is identifying how blood pressure is lowered pharmacologically. Drugs that reduce blood pressure typically do so by dilating blood vessels or decreasing the body's ability to constrict them. ACE inhibitors, like enalapril and benazepril, block the formation of angiotensin II, a powerful vasoconstrictor, and also reduce aldosterone-mediated fluid retention. That combination leads to easier blood flow and lower pressure. Prazosin, an alpha-1 adrenergic blocker, directly reduces vascular resistance by preventing norepinephrine from tightening vessels, which also lowers blood pressure. Mirataz is mirtazapine, a medication used as an appetite stimulant in cats with a different primary action on central nervous system receptors to increase appetite and affect mood. It is not used to reduce blood pressure, and it doesn’t have the same vasodilatory or anti-hypertensive mechanism. So, Mirataz is not a blood pressure reducer.
