Automated fluorometric analysis of epinephrine in lidocaine hydrochloride injection.
A rapid automated method for determining epinephrine in lidocaine hydrochloride injection is presented. The method is an adaptation of the official USP XIX fluorometric procedure and yields equivalent results. The linearity, accuracy, precision, excipient/background effect, and carryover characteristics of the automated system are described. A recovery study indicated that intact epinephrine is measured accurately in the presence of its degradation products. Analysis of several commercial preparations is reported.
