| Summary: | The method of determining Tadalafil in a mixture with a complex of vitamins and minerals by HPLC was verified to be linear, precise, selective and accurate with the use of WATERS Nova-Pack® C8 (3.9x150) mm; 4 ?m column. The mobile phase used was water:acetonitrile:trifluoroacetic acid (60:40:0.1) at the flow rate of 1 mL/min with UV detection at 285 nm at ambient temperature. Linearity was determined between 0.08 and 0.11 mg/mL with a correlation factor of 0.998. Standard deviations of performed tests of precision and accuracy were insignificant and components of the matrix did not interfere in the retention time of Tadalafil, the method is selective. |
