“…This aforementioned concentration is the mean concentration of diurethic that can be detected in the next 8 h after administration of the usual 500 mg dosage of drug. 29,41 The recovery values of HFur in urine, serum and milk samples found by application of the proposed potentiometric sensor and the comparative chromatographic methods 29,52 The concentrations of HFur added to urine samples are those usually found after administration of the usual dose of furosemide. 21,28,30-32 b Values found are the average of six determinations (n = 6) ± the corresponding standard deviation (SD).…”

“…As Tabelas 4 e 5 relacionam os fármacos que têm sido quantificados empregando métodos de separação como CLAE [161][162][163][164][165][166][167][168][169][170][171][172][173][174][175][176][177] (Tabela 4) e eletroforese capilar 50,[178][179][180][181] (Tabela 5) na análise de amostras complexas, como plasma e urina, ou na quantificação de misturas de fármacos e em estudos relacionados com bioequiva-lência, farmacocinêtica e biodisponibilidade. Desta forma, estas técnicas apresentam grande potencialidade de uso em situações específicas onde a matriz da amostra seja muito complexa.…”
