title: NMR studies of sustained release methadone tablets.
abstract: NMR studies for the identification of methadone in sustained release tablets is conducted. Up-field shifts of the N-methyl and phenyl groups of the compound were observed. These changes indicate an increased lipid solubility and therefore better absorptivity of the drug in the current form.
