A simple and sensitive method for the determination of methandienone in tablets using 1.4-dihydrazinophthalazine as the reagent is presented. The yellow coloured dihydralazinhydrazone shows the maximum at 401 nm and molar absorptivity of 1.5x104 1 mol-1cm-1. Beer's law is obeyed up to 16 μ g/ml methandienone. The method applied for the assay of methandienone in dosage form gave precise and reproducible results; recovery was 98.57. and relative standard deviation was 1.57%.
