atc code h01 atc code h01 atc code h01 pituitary and hypothalamic hormones and analogues is a therapeutic subgroup of the anatomical therapeutic chemical classification system, a system of alphanumeric codes developed by the world health organization (who) for the classification of drugs and other medical products. subgroup h01 is part of the anatomical group h systemic hormonal preparations, excluding sex hormones and insulins. atc codes h systemic hormonal preparations, excluding sex hormones and insulins h01 pituitary and hypothalamic hormones and analogues h02 corticosteroids for systemic use h03 thyroid therapy h04 pancreatic hormones h05 calcium homeostasis a b c d g h qi j l m n p r s v codes for veterinary use (atcvet codes) can be created by placing the letter q in front of the human atc code: for example, qh01. atcvet codes without corresponding human atc codes are cited with the leading q in the following list.national issues of the atc classification may include additional codes not present in this list, which follows the who version. h01a anterior pituitary lobe hormones and analogues h01aa adrenocorticotropic hormone h01aa01 corticotropin h01aa02 tetracosactide h01ab thyrotropin h01ab01 thyrotropin alfa h01ac somatropin and somatropin agonists h01ac01 somatropin h01ac02 somatrem h01ac03 mecasermin h01ac04 sermorelin h01ac05 mecasermin rinfabate h01ac06 tesamorelin h01ac07 somapacitan h01ac08 somatrogon h01ac09 lonapegsomatropin h01ax other anterior pituitary lobe hormones and analogues h01ax01 pegvisomant qh01ax90 capromorelin h01b posterior pituitary lobe hormones h01ba vasopressin and analogues h01ba01 vasopressin (argipressin) h01ba02 desmopressin h01ba03 lypressin h01ba04 terlipressin h01ba05 ornipressin h01bb oxytocin and analogues h01bb01 demoxytocin h01bb02 oxytocin h01bb03 carbetocin h01c hypothalamic hormones h01ca gonadotropin-releasing hormones h01ca01 gonadorelin h01ca02 nafarelin qh01ca90 buserelin qh01ca91 fertirelin qh01ca92 lecirelin qh01ca93 deslorelin qh01ca94 azagly-nafarelin qh01ca95 peforelin qh01ca96 salmon gonadotropin releasing hormone analogue qh01ca97 triptorelin qh01ca98 alarelin h01cb somatostatin and analogues h01cb01 somatostatin h01cb02 octreotide h01cb03 lanreotide h01cb04 vapreotide h01cb05 pasireotide h01cc anti-gonadotropin-releasing hormones h01cc01 ganirelix h01cc02 cetrorelix h01cc03 elagolix h01cc04 linzagolix h01cc53 elagolix, estradiol and norethisterone h01cc54 relugolix, estradiol and norethisterone
