Abstract
Objective: The development of nanosuspension for targeted delivery of glibenclamide as hypoglycemic agent to the lung in an inhaler dosage form.
Method: Glibenclamide nanosuspension formulations were prepared using Box–Behnken design to investigate the effect of independent factors on the dependent variables, Fourier-transform Infrared spectroscopy, Differential Scanning Calorimetry, evaluation of glibenclamide nanosuspension inhaler and in vivo hypoglycemic efficacy were performed to determine glibenclamide nanosuspension inhaler effect.
Results: The results revealed that the mean particle sizes of the prepared nanosuspension ranged from 0.216 to 0.856 µm, zeta potential from +9 to +16 mV, the solubility ranged from 43% to 75%, the mass median aerodynamic diameter was 2.34 µm and the glucose level in rat was significantly reduced by about 60%.
Conclusion: These results confirmed that glibenclamide nanosuspension inhaler enhance hypoglycemic effectiveness and reduce adverse effect of glibenclamide, opening up new dosage form in Diabetes mellitus treatment.
