Enhancement of dissolution rate of piroxicam by electrospinning technique

The use of electrospun nanofibers to enhance dissolution of poorly soluble drugs could be a novel strategy in future for pharmaceutical applications. In the present work electrospun nanofibers were prepared as a novel system for enhancing the delivery of piroxicam, a non-steroidal anti-inflammatory drug (NSAID). These nanofibers were prepared from polyvinyl pyrrolidone (PVP) (pharmaceutical grade), a biodegradable polymer, to obtain a solution with drug:polymer ratio of 1:4. The release rate of the piroxicam nanofibers was studied in simulated gastric fluid. Fourier transform infrared (FTIR) and scanning electron microscopy (SEM) are used to evaluate the chemical and physical nature. The results showed that the release rates were twice increased in comparison with the pure drug. However, the blend of drug and polymer could be varied to optimize the release rates depending upon the need and formulation
