Abstract:
In this work, the electrochemical behavior of Rosuvastatin which is a member of the drug class of statins used to treat high cholesterol and related conditions, and to prevent cardiovascular disease, was investigated with in a wide pH range (pH 0.3-7.0) using differential pulse voltammetric technique at glassy carbon electrode. All the parameters effecting the differential pulse, were optimized, and with differential pulse voltammetric techniques, the maximum peak current was observed in the 0.1 M sulfuric acid medium. Scan rate studies were also conducted using cyclic voltammetric technique, in the 0.1 M sulfuric acid medium, and the electrochemical reaction of rosuvastatin was found as diffusion-controlled mechanism. Linear relation range specified in the range of 0.005-0.1 mM and limit of detection calculated as 1.33 nM. In optimized conditions, the proposed method was applied for the determination of rosuvastatin from pharmaceutical dosage forms named, ROSUCOR (R) and REAKT (R).
