Polarographic determination of butorphanol tartrate. 1983

M E Mohamed, and E R Gad-Kariem, and H Y Aboul-Enein

A new indirect polarographic method is proposed for the determination of butorphanol tartrate in the injectable solution form (Stadol). Direct-current polarography and differential pulse polarography (DPP) were applied for the study of authentic butorphanol and its injectable solution form in alkaline medium after nitration with 1 M potassium nitrite in presence of 1 M hydrochloric acid. The standard addition method was employed for the evaluation of the results and the mean percentage found for the injectable solution form was 99.2 +/- 1.0.

D009019	Morphinans	Compounds based on a partially saturated iminoethanophenanthrene, which can be described as ethylimino-bridged benzo-decahydronaphthalenes. They include some of the OPIOIDS found in PAPAVER that are used as ANALGESICS.	Morphinan
D011048	Polarography	An electrochemical technique for measuring the current that flows in solution as a function of an applied voltage. The observed polarographic wave, resulting from the electrochemical response, depends on the way voltage is applied (linear sweep or differential pulse) and the type of electrode used. Usually a mercury drop electrode is used.	DC Polarography,Pulse Polarography,Polarography, DC,Polarography, Pulse
