The simultaneous detection in urine of cocaine (CO), and the main biotransformation products, benzoylecgonine (BE) and ecgonine methyl ester (EME), is difficult due to their different physicochemical properties. The method presented involves a bonded silica solid-phase extraction procedure that allo

## Methylphenidate (MP, Ritalin 1 ) is a psychotropic drug widely prescribed to children for treating the symptoms of attention deficit disorder with and without hyperactivity. Because little information exists about the effects of chronic MP administration on cognitive function in children, measur
A simple and sensitive HPLC method has been developed for the simultaneous determination of enrofloxacin (ENR) and ciprofloxacin (CIP) in plasma. Plasma sample preparation was carried out by adding phosphate buffer (pH 7.4, 0.1 M), followed by extraction with trichloromethane. ENR, CIP and the inter
