“…The CIP is irreversibly oxidized at high positive potentials. The electrooxidation method which is found in literature [38] related to the of CIP qualitative determination. The proposed DPV and SWV technique for the determination of CIP in pharmaceutical dosage form was found to be as simple and rapid as the reported method and more selective, sensitive and validated than the reported method [38,39].…”

The proposed DPV and SWV technique for the determination of CIP in pharmaceutical dosage form was found to be as simple and rapid as the reported method and more selective, sensitive and validated than the reported method [38,39]. The proposed voltammetric methods can be applied directly to the analysis of pharmaceutical dosage forms without the need for separation or complex sample preparation, since there was no interference from the excipients and endogenous substances.…”

“…[40][41][42] Com a VIM, informações sobre os compostos eletroativos presentes numa amostra sólida são obtidas pela varredura de potenciais e visualização dos picos de corrente, que indicam a ocorrência de reações eletroquímicas. O potencial de pico é característico do composto que reagiu, e a área do pico é proporcional à quantidade da espécie eletroativa.…”

“…Utilizando a voltametria de onda quadrada, determinaram o limite de detecção para a concentração superficial de cocaína como sendo 0,3 μg cm -2 . Komorsky-Lovric e Nigovic 41 utilizaram as técnicas de voltametria cíclica e voltametria de onda quadrada na determinação qualitativa dos fármacos ácido 5-aminosalicílico, ciprofloxacina e azitromicina. Já em outro trabalho, 40 os mesmos autores investigaram as propriedades eletroquímicas da sinvastatina sólida e em solução, a fim de desenvolver métodos para a análise qualitativa e quantitativa de sinvastatina em formulações farmacêuticas.…”
