Abstract
Recently, high demand of high-throughput analyses with high sensitivity and selectivity to molecules and drugs in different classes with different physical-chemical properties—and a reduction in analysis time—is a principal milestone for novel methodologies that researchers are trying to achieve—especially when analytical procedures are applied to clinical purposes. In addition, to avoid high doses of a single drug that could cause serious side effects, multi-drug therapies are often used to treat numerous diseases. For these reasons, the demand for methods that allow the rapid analysis of mixed compounds has increased in recent years. In order to respond to these needs, new methods and instruments have been developed. However, often the complexity of a matrix can require a long time for the preparation and processing of the samples. Different problems in terms of components, types of matrices, compounds and physical-chemical complexity are encountered when considering drugs association profiles for quantitative analyses. This review addresses not only recently optimized procedures such as chromatographic separation, but also methods that have allowed us to obtain accuracy (precision and trueness), sensitivity and selectivity in quantitative analyses for cases of drug associations.

Abstract
Abstract
This manuscript describes a responsive, rapid, validated and economical spectrofluorimetric method for determination of Melphalan in its pharmaceutical dosage forms and spiked human plasma. The proposed method is relied on the investigation of fluorescence action of Melphalan in Tween-80 micellar system. The Melphalan shows strong native fluorescence at λem 365 nm upon excitation at λex 265 nm in Tween-80 system. There was good enhancement (1.68 fold) in fluorescence intensity in the presence of Tween-80. The proposed approach has a good linearity in the concentration range of 0.2 μg/mL–2 μg/mL. The lower limit of detection and that of quantitation was 0.03 μg/mL and 0.08 μg/mL respectively. The developed method has been validated and applied for content uniformity testing of Melphalan medicines available on the market and Melphalan spiked human plasma samples. The results are statistically compared and were found to be in good agreement to those obtained by comparison methods.
