Burinex ® Product Information 1 ( 7) BURINEX ® PRODUCT INFORMATION (bumetanide) NAME OF THE MEDICINE Burinex ® 1 mg tablets contain bumetanide i.e. 3-n-(butylamino)-4-phenoxy-5-sulphamoyl-benzoic acid. The structural formula of bumetanide is: The CAS registry number is 28395-03-1. DESCRIPTION Bumetanide is a derivative of metanilamide, and is therefore structurally different to frusemide and the thiazides which are derivatives of sulphanilamide. It is a white odourless crystalline powder with a slightly bitter taste. It melts at approximately 230 °C and at 22 °C is soluble in ethanol and acetone; slightly soluble in ether and chloroform, very slightly soluble in water and practically insoluble in hydrochloric acid. It should be protected from light. The molecular weight is 364.41. PHARMACOLOGY Pharmacodynamics: Burinex ® is a loop diuretic with a rapid onset and short duration of action. Pharmacological and clinical studies have shown that 1mg bumetanide has a diuretic efficacy equivalent to approximately 40mg frusemide. The major site of action is the ascending limb of the loop of Henle where it inhibits sodium reabsorption. Reabsorption of chloride in the ascending loop is also blocked by bumetanide. The excretion of chloride is greater than that of sodium and bumetanide also increases potassium excretion in a dose-related fashion. Bumetanide decreases uric acid excretion and increases serum uric acid. Bumetanide may have an additional action on the proximal tubule. This proximal tubular activity does not seem to be related to an inhibition of carbonic anhydrase. Bumetanide does not exert an observable effect on the distal tubule. The diuretic effect of bumetanide is dose-related so that Burinex ® Product Information 2 ( Read the complete document
