title: Rapid near IR spectrophotometric determination of meprobamate in pharmaceutical preparations.
abstract: A rapid near IR spectrophotometric method was developed for determining meprobamate in tablets, sustained-release capsules, suspensions, and injectables. The absorbance of a chloroform solution of the drug is obtained at about 1.96 mum for quantitation. Assay of nine commercial products from four different manufacturers gave results ranging from 97 to 104% of label claim. Coefficients of variation of 0.7 and 1.3% were obtained on the tablets and a sustained-release product, respectively.
