title: Screening of counterfeit corticosteroid in creams and ointments by NMR spectroscopy.
abstract: It has been shown that NMR spectroscopy is an effective analytical method to rapidly screen creams and ointments for counterfeit corticosteroids. Extraction and NMR procedures have been developed. Ten over the counter creams and ointments sold in health care shops were screened and two creams were found to contain counterfeited corticosteroids.
