Application of orthogonal functions to the spectrophotometric determination of phenytoin in pharmaceutical preparations.
A simple ultraviolet spectrophotometric method for the determination of phenytoin in pharmaceutical preparations has been developed. The mean was 100.9% (6 determinations) and the coefficient of variation was 1.2%. The method was applied successfully to the determination of phenytoin in capsules and suspensions.
