ABSTRACT
Introduction: Microspheres can be defined as a matrix system that allows the drug to be homogenously dispersed, dissolved or suspended. Aim: Development and in vitro evaluation of ibuprofen floating microspheres. Methods: The microspheres were formulated using inotropic gelation method. A homogenous polymer solution was prepared by dissolving sodium alginate (1 g) and the polymers (1 g each) in 32 ml of distilled water. The drug was added to the polymer solution and stirred continuously to form a viscous dispersion. A 10 % w/v Cacl2 solution was prepared and used as a cross–linking agent. The dispersion was added drop wise for 15 minutes for the curing reaction to take place. The spheres obtained were then washed and dried at 45 oC for 12 hours. Results: The percentage yield of the formulations ranged from 72.00 % ± 1.41 to 85.50 % ± 3.54. The angle of repose ranged from 3.49o ± 0.04 to 9.49o ± 0.31, while the bulk density ranged from 0.60 g/ml ± 0.00 to 0.41 g/ml ± 0.00. The Carr’s index ranged from 13.04 % ± 0.04 to 14.50 % ± 0.35. The swelling index ranged from 65.50 % ± 0.35 to 85.00 % ± 0.71. The in vitro drug release showed that formulation F-5 gave the least release at 28.80 % ± 0.85 after 4 hours without a significant difference (p < 0.05). Conclusion: The idea of formulating floating microspheres containing ibuprofen gave a suitable practical approach that achieved a prolonged therapeutic effect by releasing the active drug over an extended period of time.
