DEVELOPMENT AND CHARACTERIZATION OF TRANDOLAPRIL IMMEDIATE RELEASE TABLETS USING DIFFERENT SUPERDISINTEGRATING AGENTS

A potent non-sulfhydryl prodrug, trandolapril is transformed into the active substance, trandolaprilat, in the liver. For obese individuals with mild-to-moderate essential hypertension, Trandolapril is effective and safe. The elimination t1/2 of trandolapril and trandolaprilat are approximately 6 hours and 16–24 hours, respectively. The goal of present work is to develop the Trandolapril immediate release tablet using various superdisintegrants. Crospovidone, Sodium starch glycolate and Croscarmellose sodium in concentrations of 2%, 4%, and 6% were used as superdisintegrating agents for the optimization. Direct compression technique was used to make nine formulations (IRTR 1 to IRTR 9). The powder blends of all batches were evaluated for different parameters to know the powder flow characteristics and it was found that the powder blend had excellent flow and compressibility characteristics. Then, compressed tablets were tested for quality control parameters as per the IP. In formulation IRTR1-IRTR9, disintegration time was observed 30.23 to 71.67 Sec and more than 70% drug was released in 30 min. Thus, based on evaluation results, it is concluded that formulation of immediate release (IR) tablets of Trandolapril were successfully developed. Minimum disintegration time 30.23 seconds 90.56% drug release in 30 min was obtained with IRTR3. KEYWORDS: Trandolapril, Immediate release, Crospovidone, Sodium starch glycolate, crocarmellose sodium
