atc code g04 atc code g04 atc code g04 urologicals 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 g04 is part of the anatomical group g genito-urinary system and sex hormones. atc codes g genito-urinary system and sex hormones g01 gynecological antiinfectives and antiseptics g02 other gynecologicals g03 sex hormones and modulators of the genital system g04 urologicals atcvet only qg51 antiinfectives and antiseptics for intrauterine use qg52 products for teats and udder 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, qg04. 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. g04b urologicals g04ba acidifiers g04ba01 ammonium chloride g04ba03 calcium chloride qg04ba90 methionine g04bc urinary concrement solvents empty group g04bd drugs for urinary frequency and incontinence g04bd01 emepronium g04bd02 flavoxate g04bd03 meladrazine g04bd04 oxybutynin g04bd05 terodiline g04bd06 propiverine g04bd07 tolterodine g04bd08 solifenacin g04bd09 trospium g04bd10 darifenacin g04bd11 fesoterodine g04bd12 mirabegron g04bd13 desfesoterodine g04bd14 imidafenacin g04be drugs used in erectile dysfunction g04be01 alprostadil g04be02 papaverine g04be03 sildenafil g04be04 yohimbin g04be05 phentolamine g04be06 moxisylyte g04be07 apomorphine g04be08 tadalafil g04be09 vardenafil g04be10 avanafil g04be11 udenafil g04be30 combinations g04be52 papaverine, combinations qg04bq urinary alkalizers qg04bq01 sodium bicarbonate g04bx other urologicals g04bx01 magnesium hydroxide g04bx03 acetohydroxamic acid g04bx06 phenazopyridine g04bx10 succinimide g04bx11 collagen g04bx12 phenyl salicylate g04bx13 dimethyl sulfoxide g04bx14 dapoxetine g04bx15 pentosan polysulfate sodium g04bx16 tiopronin qg04bx56 phenazopyridine, combinations qg04bx90 ephedrine qg04bx91 phenylpropanolamine g04c drugs used in benign prostatic hypertrophy g04ca alpha-adrenoreceptor antagonists g04ca01 alfuzosin g04ca02 tamsulosin g04ca03 terazosin g04ca04 silodosin g04ca51 alfuzosin and finasteride g04ca52 tamsulosin and dutasteride g04ca53 tamsulosin and solifenacin g04ca54 tamsulosin and tadalafil g04ca55 doxazosin and finasteride g04cb testosterone-5-alpha reductase inhibitors g04cb01 finasteride g04cb02 dutasteride g04cb51 finasteride and tadalafil g04cx other drugs used in benign prostatic hypertrophy g04cx01 prunus africanae cortex g04cx02 sabalis serrulatae fructus g04cx03 mepartricin g04cx04 fexapotide qg04cx90 osaterone
