title: Direct extraction procedure for the analysis of neutral drugs in tissue.
abstract: This paper describes an efficient extraction technique for the determination of neutral drugs in tissue. The extracts are clean and can be analyzed by gas liquid chromatography. The method gives good recoveries of most of the neutral drugs and the sensitivity is such that therapeutic levels can easily be detected.
