Furosemide-induced thiamine deficiency. 1980

Y Yui, and Y Itokawa, and C Kawai

Male Wistar rats were separated into 4 groups: group 1, thiamine sufficient diet (control); group 2, thiamine sufficient diet with intraperitoneal administration of furosemide (20 mg . kg-1 of body weight); group 3, thiamine deficient diet; group 4, thiamine deficient diet within tra-peritoneal administration of furosemide. After 4 weeks, the rats were killed and the thiamine levels and activity of transketolase were assayed. Thiamine concentration and transketolase activity were significantly decreased and thiamine pyrophosphate effect was significantly increased in the blood, and various tissues in group 2 and 4 compared with group 1 and 3, respectively. The intraperitoneal administration of various concentrations of furosemide (20 mg, 10 mg, and 2 mg . kg-1 of body weight) resulted in a significant increase in urinary thiamine excretion. Thus, it is assumed that long-term administration of furosemide could induce a thiamine deficiency.

D005665	Furosemide	A benzoic-sulfonamide-furan. It is a diuretic with fast onset and short duration that is used for EDEMA and chronic RENAL INSUFFICIENCY.	Frusemide,Fursemide,Errolon,Frusemid,Furanthril,Furantral,Furosemide Monohydrochloride,Furosemide Monosodium Salt,Fusid,Lasix
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013831	Thiamine	3-((4-Amino-2-methyl-5-pyrimidinyl)methyl)-5-(2- hydroxyethyl)-4-methylthiazolium chloride.	Aneurin,Vitamin B 1,Thiamin,Thiamine Mononitrate,Vitamin B1,Mononitrate, Thiamine
D013832	Thiamine Deficiency	A nutritional condition produced by a deficiency of THIAMINE in the diet, characterized by anorexia, irritability, and weight loss. Later, patients experience weakness, peripheral neuropathy, headache, and tachycardia. In addition to being caused by a poor diet, thiamine deficiency in the United States most commonly occurs as a result of alcoholism, since ethanol interferes with thiamine absorption. In countries relying on polished rice as a dietary staple, BERIBERI prevalence is very high.
