Statistically (L 25 via CCD 20 ), a novel array via response surface analytical process was an attempt to develop a quantification of the pharmacies/bulk, Isradipine using organic medium (methanol & chloroform) as solvent. During analysis, the maximum absorption wavelength of model drug was found at lambda max 327nm and also done its recovery via validation further. In the beginning, by using a quality improvement statistically array looms (Taguchi) was generated numerous level/space (s) of the independent variable (A=methanol; B=chloroform & C=ratio of A: B) by performing experimentally (L 25 array runs to studied their response to be found the finer spaces). Additionally, a three-dimensional response surfaces strategy [RSM; three dimensional central composite designs (CCD 20 )] explored variables non-factorial levels which are used as fine. Also, responses quadratic (02 nd order) equation of response (Y=absorption) was predicted analytically for "finer to finest" (2.5 to 15μg/ml) by analysis alone variable space as well as together. Thus, newfangled Beer's finest in-terms of linearity, precision, sensitivity and accuracy during analysis range was found and also validated for further, finest determination. As well, economically inexpensive quantitative can be titled as newfangled analytical estimation of Isradpine (CCB s; Calcium channel blocker) in bulk/Pharmacia forms.
