↵9-a These abbreviations are proposed to establish and maintain consistency with existing internationally authoritative nomenclature databases (e.g., GDB, MEDLINE). Alternative abbreviations to denote the species when using trivial receptor names have been published by NC-IUPHAR, and these are still appropriate for use in textual discussion referring to trivial names (see Vanhoutte et al., 1996).
