Abstract
Aspirin and dipyridamole in pure admixtures and in dosage forms have been estimated by spectrofluorometry. Aspirin (2–12 mcg ml −1) was estimated in 1% v/v glacial acetic acid in chloroform using 246 and 345 nm for excitation and emission respectvely. Dipyridamole (2–12 mcg ml −1) has been estimated in chloroform using 420 nm for excitation and 475 nm for emission. The non-interference of the excipients as well as the drugs in the estimation of each other, as evidenced by the results, indicate that this method may be used for the routine estimation of aspirin and dipyridamole in tablet preparations.
