This study was conducted to enhance the pharmacologic effect of carbamazepine (CBZ) (as a poorly water-soluble drug) by fabricating CBZ-PVP K30 nanobeads using an electrospraying technique. CBZ-PVP K30 nanosystems with various ratios (1:3 and 1:5) at total solution concentrations of 3% and 5% w/v were prepared. The solution concentration extremely affected the size of the samples; where, the nanobeads (mean diameter of 457.65 ± 113.72 nm and 1.16 ± 0.46 µm) were developed at low and high solution concentrations, respectively. DSC thermographs and PXRD patterns precisely showed CBZ amorphization in the electrosprayed nanosystems. Based on the FTIR spectrum of the electrosprayed samples, a feasible interaction between N–H/O–H group of CBZ and PVP carbonyl group was detected. The in-vitro release studies revealed that the electrosprayed nanosystems represent a comparable rapid dissolution rate with respect to the physical mixtures (PMs) and the pure drug. The in-vivo results in NMRI mice indicated that the electrosprayed nanoformulation (with the drug: polymer ratio of 1:5 at a total solution concentration of 5% (w/v)) prolonged seizure latency time and decreased mortality percent in strychnine (STR) induced seizure mice more efficiently than the PM. Our finding revealed that the electrospraying as a cost-benefit and one step technique could be effectively applied for improving the physicochemical characteristics and pharmacologic effect of CBZ.
