Perindopril (S-9490) is a long-acting ACE inhibitor effective for 24 hours, primarily utilized in the management of high blood pressure, heart failure, or stable coronary artery disease. Available as perindopril arginine (with trade names such as Coversyl and Coversum) or perindopril erbumine (known as Aceon), both formulations are regarded therapeutically equivalent, according to the Australian Government's Pharmaceutical Benefits Scheme—meaning they can be interchanged without clinical effect differences, though their dosing may vary due to distinct molecular weights. Notably, perindopril ranks among the most frequently prescribed ACE inhibitors, thanks to its extensive evidence base supporting its use in patients with hypertension, type 2 diabetes, coronary heart disease, and chronic heart failure. This review highlights perindopril's organoprotective benefits that extend beyond its capacity to lower blood pressure.

Guanfacine-13C,15N3is intended for us as an internal standard for the quantification of guanfacine by GC- or LC-MS. Guanfacine is an α2-adrenergic receptor (α2-AR) agonist with Kivalues of 93, 1,380, and 3,890 nM for α2A-, α2B-, and α2C-ARs, respectively, in a radioligand binding assay.1It has EC50values of 52, 288, and 602 nM for α2A-, α2B-, and α2C-ARs, respectively, for stimulated [35S]GTPγS binding. It also binds to imidazoline receptor 1 (Ki= 19 nM in a radioligand binding assay).2Guanfacine (0.3-5 mg/kg) binds to adrenergic receptors in the central nervous system and lowers blood pressure in hypertensive rats in a dose-dependent manner.3It also improves spatial working memory deficits induced by hypobaric hypoxia in rats.4Formulations containing guanfacine are used in the treatment of high blood pressure and attention deficit hyperactivity disorder (ADHD). 1.Jasper, J.R., Lesnick, J.D., Chang, L.K., et al.Ligand efficacy and potency at recombinant α2 adrenergic receptors: Agonist-mediated [35S]GTPγS bindingBiochem.
