Objective: Focus of the study was to formulate Design expert Software assisted floating tablet of Bisoprolol Fumarate. Bisoprolol Fumarate is a Beta adrenergic blocking agent, used to treat cardiac diseases favorable characters to be formulated as sustained release Gastro retentive floating tablets.
Methods: Floating Tablets of Bisoprolol Fumarate were prepared by using polymers such as Polyox N 12 K and Carbapol 940 P. Formulations were prepared by using direct compression method and evaluated for various parameters like Hradness, thickness, weight variations, Floating lag time Total floating time,% drug release and Stability Study etc.
Results: FTIR spectroscopic study indicates no drug-excipients interaction in the prepared formulations. Hardness or crushing strength of the tablets of all the formulation was found between 5.8 and 6.5 kg/cm2. Floating lag time of all batches is in range of 1.18±2.0 to 2.43±1.6 (minutes). All other parameters of all batches are within an acceptable range. The polymer Carbopol 940 P had the significant negative effect of on the floating lag times. The In vitro dissolution profiles of optimized A3 Floating formulation of Bisoprolol Fumarate were found to sustain drug release 99.25 % up to 12 h with floating lag time of 1.45 min; Designed formulation was stable after Stability study. Optimization study was carried out by using 32 factorial designs to fabricate formulations.
Conclusion: It can be conclude that reproducible results of various parameters in this developed formulation can easily scale up. Furthermore designed formulation will be very effective for controlling blood pressure.
