اقترحت طريقة طيفية تفلورية حساسة و بسيطة لتحديد الكابتوبريل (CPT) في الحالة النقية و في المستحضرات الصيدلانية. اعتمدت الطريقة على تشكيل معقد بين الكابتوبريل و أيونات النحاس عند قيمة pH=3.5.
A sensitive, simple and selective spectrofluorimetric method
has been proposed for determination Captopril (CPT) in pure form
and pharmaceutical preparations. This method depends on the
formation of complex between Captopril and Copper (II) at
pH=3.5.

The voltammetric behavior of captopril in presence of
copper ions was investigated by using adsorptive cathodic stripping
voltammetry at hanging mercury drop electrode.
Simple, accurate and reliable spectrophotometric method
has been developed for the quantitative determination of
Cephalosporins: Cefaclor, Cefalexin, Cefadroxil in pure and
pharmaceutical formulations. The method is based on the
determination of that in aqueous medium pH=6.45 at
25±0.5ºC.
A new, simple and sensitive kinetic spectrophotometric
method has been proposed for the determination of tropicamed

New, accurate, sensitive and reliable kinetic spectrophotometric
method for the assay of fluvastatin sodium (FVS) in pure form and
capsules has been developed. The method involves the oxidative
coupling reaction of FVS with 3-methyl-2-benzothiazolinone hydrazone
hydrochloride monohydrate (MBTH) in the presence of Ce(IV) in an
acidic medium to form colored product with lambdamax at 615 nm.
