Notes: Tetrahydrozoline is an α1-adrenergic receptor (α1-AR) agonist.{41103} Topical application to the eyes or nasal mucosa activates α1-ARs and induces vasoconstriction in rats, while oral administration activates central α2-ARs resulting in respiratory depression and hypotension in rats and rabbits.{41103,41104,41105} Formulations containing tetrahydrozoline have been used to treat eye irritation and nasal congestion.{41103}
