Abstract
Construction of New Coated Carbon Electrodes for Determination of Sildenafil Citrate Drug
Highlights
Viagra (Sildenafil citrate SILC) is a white to off-white crystalline powder of molecular weight of 666.7 g/mole and its formula is C28H38N6O11S
The studies show that Viagra successfully treats erectile dysfunction in men with co morbidities such as hypertension [4], diabetes [5], and depression [6].The side effects of SILC have been reported such as headache, congestion, flushing and dyspepsia [7,8,9]
Elemental analysis and FT-IR spectroscopy was carried out to confirm the composition of the ion-pair (SILC-phosphotungstic acid (PTA)) and (SILC-PMA)
Summary
Viagra (Sildenafil citrate SILC) is a white to off-white crystalline powder of molecular weight of 666.7 g/mole and its formula is C28H38N6O11S. The studies show that Viagra successfully treats erectile dysfunction in men with co morbidities such as hypertension [4], diabetes [5], and depression [6].The side effects of SILC have been reported such as headache, congestion, flushing and dyspepsia [7,8,9]. The present work describes preparation, characterization and application of coated carbon electrodes for determination of Viagra in pure and pharmaceutical preparations. Performance characteristics of (SILC-PMA) and (SILC-PTA) coated carbon electrodes reveal low detection limit, high sensitivity, good selectivity, fast response time, very long life time and application with accurate determination of Viagra in pharmaceutical preparations
