Abstract:


Aim: The present research work was aimed to formulate fast disintegrating tablets (FDTs) of salbutamol sulphate (SBS) using a combination of a superdisintegrant and a subliming agent, optimize the formulation and evaluate the in vitro performance of the developed FDTs.

Materials and Methods: A formulation of SBS FDT was developed using a combination of superdisintegrant - crospovidone and subliming agent - Ammonium Bicarbonate (AB) in which formulation variables, namely levels of crospovidone and Microcrystalline Cellulose (MCC):Mannitol (MNTL) ratio, were evaluated for their effects on the response variables, disintegration time, hardness, friability and wetting time, of the resulting FDTs. By employing Central Composite Design (CCD) methodology, the FDTs were optimized to achieve optimum levels of the formulation factors.

Results: The desired optimum condition was obtained at 7.82% crospovidone and 70% of 1.56:1 MCC: MNTL ratio, while maintaining AB at 5% level for aesthetic reasons. Under the optimized conditions, the disintegration time, hardness, friability, and wetting time were 14.57 ± 0.53 sec, 7.17 ± 0.82 kg/cm2, 0.311% and 13.14 ± 0.69 sec, respectively. The experimentally observed responses were found to be in close agreement with the predicted values for the optimized formulation. Moreover, the validity of the obtained optimal point was confirmed by the low magnitude of percent prediction error (< 5%).

Conclusion: FDTs of SBS were successfully formulated and optimized using CCD employing a combination of a superdisintegrant and a subliming agent.
