ABSTRACT

Aim:Milnacipran is well used drug for the treatment of depression and fi bromyalgia. Its short elimination half-life, frequent dosing and associated side effects cause lack of patient compliance and discontinuation of present therapy. To overcome such problems, the aim of the present study was to design a novel multi granules based controlled release (CR) formulation with simplex lattice technique and study the various formulation variables. Materials and Methods:Hydrophilic polymeric and hydrophobic wax granules were prepared separately, and various formulations were designed with different proportion of these granules. Results: As the proportion of hydrophobic granules in formulation increased from 0% to 100%, the mean dissolution time, time for 50% and 80% drug release extended from 4.88-8.95 h; 3.11-9.11 h and 10.51-20.72 h, respectively. All the formulations were following fi rst-order release kinetic. Results of formulation variables indicated that viscosity of the polymer, hardness of tablets and agitation speed can signifi cantly infl uence the drug release from formulations and no signifi cant effect observed for pH of dissolution media. In vitro human plasma concentrations were predicted from in vitro release data using convolution method.Conclusion: Novel multi granule-based CR tablet formulations of milnacipran hydrochloride were designed and evaluated for its in vitro release.
