Abstract
Benzhydrol, an impurity in some samples of cyclizine hydrochloride, interferes with the colorimetric estimation of ergotamine in preparations containing ergotamine tartrate and cyclizine hydrochloride. A method for overcoming this difficulty is described. The inhibition of colour development has been utilised to provide a method for the detection and estimation of benzhydrol in cyclizine hydrochloride.
