The study of guar gum and starch on disintegration time and drug release of fast dissolving tablet in rabbit using single dose randomized parallel design method

الملخص EN

The aim of this study is to find the effect of starch and guar gum 4000 on disintegrating time and dissolution behavior of drug Zolmitriptan from fast dissolving tablet (FDT).

The FDT was prepared by direct compression method.

The precompression parameters were evaluated with subjected to angle of repose, bulk and tapped density, hausner’s ratio and Carr’s index and all were within limit.

The prepared tablets were evaluated for thickness, uniformity of content, hardness, friability, wetting time and in vitro disintegration time and in vivo release of drug.

The in vitro release and assay of drug was performance by UV spectrophotometer.

The in vivo study reveals that when guar gum (5%) and starch (10%) were used in formulation, the plasma concentration of drug was increased because, it disintegrate tablet rapidly and drug was released rapidly from dosage form and reach quickly in to systemic circulation resultant bioavailability is increased.
