BackgroundAlbendazole is an orally administered broad-spectrum anthelmintic. Currently it is mostly used in the treatment of soil transmitted helminthes, hydatidosis and neurocysticercosis caused Taenia solium.Aim of the study. To develop and optimize a formulation of chewable albendazole tablet with improved dissolution rate.MethodologyThis study was specifically focused on formulation development which passes compatibility studies and optimization of the developed formulation. The formulations were evaluated on assay, dissolution, friability, hardness, weight variation, disintegration and similarity in comparison with the reference product on the market. Analysis was required to be undertaken by High performance thin layer chromatography (HPTLC) analytical methods. Design of Expert version 7 software was used for selection or making scientific decisions in selecting the best composition of the best formulation.ResultsFive formulations out of ten (F-6, F-7, F-8, F-9 and F10) had all parameters in acceptable range. On optimization, one formulation with independent variables, Sodium Laury Sulphate (SLS) 1.911%, polyvinyl pyrrolidone (PVP-K30) 3.128%, and Sodium Cross carmellose (CCM) 4.95% was selected out of ten predictions made with Design expert version 7.0. It was found that assay of the best formulation is 99.23% which was within the in-house assay specification 95–105%. Dissolution single point in 30 min was found to be 91.5% disintegration between 2-5 min and friability 0.45%.The optimized formulation was tested and found to be within the acceptable limits. The formulation was comparable to the reference product on the market with similarity factor (f2) 62 and difference factor (f1) of 6 at pH1.2.ConclusionA new generic albendazole tablet with improved dissolution rate was formulated, developed and optimized by using a wet granulation method.
