Formulation and evaluation of floating microspheres of ciprofloxacin by solvent evaporation method using different polymers.
Objective: The main intention of this research was to formulate and evaluate floating microspheres of Ciprofloxacin using different polymers to prolong gastric residence time.
Methods: The microspheres were formulated by the solvent evaporation method using different ratio of polymers like Carbopol 940, Ethyl cellulose and Hydroxy Propyl Methyl Cellulose K4M. Further the floating microspheres were evaluated for micromeritic properties like bulk density, tapped density, angle of repose, etc., percentage yield, Particle size, Entrapment efficiency, floating capacity, in-vitro drug release study, release kinetics, drug content, swelling index and Fourier Transform Infrared Spectroscopy (FTIR) (Compatibility studies).
Results: The ciprofloxacin microspheres showed good flowing property. The particle size ranged from 258.1±2.21µm to 278±2.86µm and entrapment efficiency ranged from 63.17±0.43% to 89.90±1.32%. The IR spectrum revealed that there was no interaction between the drug and polymer. F7 formulation was found to be the best formulation. Drug release was to found to be 90.70±0.89% i.e. in the controlled manner at the end of 10 h.
Conclusion: The floating microspheres were prepared successfully and the results clearly stated that prepared ciprofloxacin microspheres may be safe and effective controlled drug delivery over an extended period of time which can increase bioavailability, patient compliance and decrease dosing frequency.
