Spectrofluorometric determination of pindolol and its dosage form

A new direct, simple, and sensitive spectrofluorometric method is described for the assay of pindolol and its tablets at room temperature, using ethanol (96% v/v) as solvent. The drug exhibits intrinsic fluorescence. Working wavelengths are 263 nm for excitation and 305 nm for emission. The calibration curve is linear in the range 1.0 X 10(-7) to 1.5 X 10(-6)M pindolol.
