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.
