Abstract
AbstractThe aim of present study was to prepare sustained release formulations of niosomes of methotrexate (MTX) alone (N1 to N10) and along withbioenhancers (NB1 to NB9) by thin film hydration technique using span 60 as surfactant,cholesterol as membrane stabilizing agent, curcumin and piperine as bioenhancers and dicetyl phosphate (DCP) as charge inducing agent. All the formulations of niosomeswere characterized on the basis of physical appearance and entrapment efficiency. The invitro releasestudies of optimized formulation of niosomes of MTX alone and along with bioenhancers were performed and compared with pure drug released. The entrapment efficiency of MTX in optimized formulation of niosomes containing MTX along with bioenhancers was found to 56.9% and entrapment efficiency of bioenhancerscurcumin and piperinewas found to be 40.30% and 69.1%respectively. In vitro drug release of optimized formulationsof niosomes of MTX without and with bioenhancers (F3) was found to be 98.89% and 60.97% at the end of 12 h respectively. Results concluded that Niosomes of MTX containing bioenhancers followed sustain release pattern.
