A high-performance liquid chromatographic analysis of phenylpropanolamine in human serum and urine without prior derivatization is presented. Using direct UV detection the method is sufficiently sensitive to detect 25 ng of drug/ml of serum or urine; the coefficients of variation

Different organic borates, phosphates, sulphates, and carboxylic acids are evaluated as extraction carriers in three-phase liquid-phase microextraction (LPME). Hydrophilic basic drugs form ion-pairs with the carriers and are extracted as ion-pair complexes into an organic liquid membrane of n-octanol or

The objective of this study was to tailor a drug release profile through the adjustment of some key processing parameters involved in melt-extrusion: die temperature, shear rate, die length and drug particle size. Two experimental designs were selected, namely a
Many patients with incontinence do not need surgery - for these patients symptoms can often be considerably improved by conservative measures, including drugs. Several different pharmacological actions are potentially useful depending on the underlying cause of the incontinence: a) Detrusor
A 20-year-old woman using an oral diet aid preparation containing phenylpropanolamine presented with an intracerebral hemorrhage and angiographic evidence of cerebral vasculitis. Gas chromatography demonstrated phenylpropanolamine in the urine. Even when used within recommended guidelines, phenylpropanolamine usage should be included
