TLDR A new, simple, and accurate method was created to measure finasteride in tablets.
The study developed and validated a rapid, simple, and cost-effective RP-TLC method combined with densitometry for quantifying finasteride in tablet dosage forms. Chromatographic analysis was performed using silica gel plates and a 1,4-dioxane-water mobile phase, with densitometric scanning at 212 nm. The method showed high accuracy and precision, with a coefficient of variation less than 2%, and was linear over the range of 1.00-4.00 µg/spot with a correlation coefficient of 0.9981. The limits of detection and quantification were 0.24 and 0.74 µg/spot, respectively. The assay results for finasteride in marketed tablets were consistent with label claims and pharmacopoeial standards, indicating the method's suitability for routine analysis.
