Drug used in diabetes is:

Acetohexamide is a first-generation sulfonylurea medication used to treat diabetes mellitus type 2. Salmeterol is a beta 2-selective agonist with a prolonged duration of action (>12 hours). Benserazide is a peripherally-acting aromatic L-amino acid decarboxylase or DOPA decarboxylase inhibitor, which is unable to cross the blood-brain barrier. Methoxamine acts pharmacologically like phenylephrine, since it is predominantly a direct-acting 1-receptor agonist. It may cause a prolonged increase in blood pressure due to vasoconstriction; it also causes a vagally mediated bradycardia. Ref: Biaggioni I., Robeson D. (2012). Chapter 9.
