Abstract:
Furosemide 4-chloro-2-[(furan-2-ylmethyl) amino]-5- sulfamoylbenzoic acid, is widely used as diuretic for the treatment of high blood pressure and fluid retention caused by heart failure or kidney disease. It is considered as a loop diuretic, which inhibits the re-absorption of sodium in the thick ascending limb of the loop of Henle and it is effective in cases of renal failure. Furosemide is characterized by a low solubility and poor permeability in the upper GI tract, thus is classified in the BCS system, as an IV drug. However, with the entrance of furosemide in intestinal fluids a rapid release of the drug occurs, which is accompanied by an increased natriuretic and diuretic effect, causing displeasure to the patients. As a result, a slow release formulation would be probably preferred by patients, because of a lower initial diuretic effect and a more extended duration of action. To this end, we extended our previous research on the modified release of this drug by using PVP and different grades of Eudragit polymers. Eudragits are commonly used when it is required to modify the release rate, and the different grades of polymer offer a variety of physicochemical properties depending on what is desired. These excipients were formulated, in the context of this work, in matrix systems for oral administration.
