Abstract
Atenolol is beta blocker absorbed through GIT use for heart diseases. Single tablets, floating tablets and sustained released formulations studied are insufficient to produce effective dose to enhance bioavailability and effectiveness. Our study is focused on development of capsule dosage form containing immediate release (IR) and floating extended release (ER) tablets for monitoring release of atenolol in single dosage form. Two different tablets for IR and ER were prepared in three different combinations (Batch). Pre-formulation and post formulation parameters found to be within acceptable limits of formulation. Release behavior of individual tablets and capsule containing two tablets were studied. Among the batches, capsules containing smaller amount of atenolol in IR and large amount of Atenolol in ER (batch II) showed impressive drug release pattern. This formulation was stable even after a month and achieved optimum release behavior of immediate release and sustained release. This study could be used for effective treatment for different heart complications and reduce toxicity due to high plasma concentration in increased dose frequency.
