In the NEALSIVMAN drug acronym, which drug corresponds to the first N?

Explanation:
In NEALSIVMAN, the N stands for a drug used as a vasopressor, and the first N specifically corresponds to Neosynephrine, which is phenylephrine. Phenylephrine is a pure alpha-1 adrenergic agonist, so it produces peripheral vasoconstriction to raise blood pressure with little to no direct effect on the heart. That makes it a common first choice to treat acute hypotension from vasodilation during anesthesia. The other drugs starting with N (like noradrenaline) don’t fit this first-position mapping in the mnemonic, and the other options are vasodilators or have mixed actions, not the alpha-1–selective pressor represented by the first N.
