In this research paper we describe validated high-performance liquid chromatographic (HPLC) and high-performance thin-layer chromatographic (HPTLC) methods for simultaneous analysis of tamsulosin hydrochloride and dutasteride in tablet formulations. HPLC was performed on a C 18 column with 85:15 ( υ/υ ) methanol-0.02 M ammonium acetate buffer (pH 9.5, adjusted with triethylamine) as mobile phase. HPTLC was performed on aluminium foil-backed silica gel G60F 254 layers with toluene-methanol-triethylamine 9:1.5:1 ( υ/υ/υ ) as mobile phase. In HPLC, quantification was achieved by photo diode-array (PDA) detection at 274 nm over the concentration range 1–20 μg mL ^-1 for both; mean recovery was 98.18 ± 0.698 and 99.94 ± 0.611% for TAM and DUTA, respectively. In HPTLC, quantification was achieved by UV detection at 280 nm over the concentration range 200–2000 ng per band for both; mean recovery was 99.66 ± 0.892 and 100.05 ± 1.012% for TAM and DUTA, respectively. These methods are simple, precise, and sensitive, and are suitable for simultaneous analysis of TAM and DUTA in tablet formulations.
