    • A polarographic study of the photodegradation of nitrendipine 
      Squella Serrano, Juan; Zanocco, A.; Perna, S.; Núñez Vergara, Luis (1990)
      Nitrendipine produces a well-defined polarographic peak due to the four-electron reduction of the nitro group. This peak is used for tracking the photodecomposition of nitrendipine in both UV light and daylight conditions. ...
    • Folarographic behaviour of nitrendipine 
      Squella Serrano, Juan; Perna, S.; Núñez Vergara, Luis (1988)
      Nifedipine, a calcium antagonist drug, produces a well-defined polarographic wave due to the four-electron, four-proton reduction of the nitro group. This peak is diffusion-controlled and shows a linear dependence on the ...
    • Nifedipine: Differential pulse polarography and photodecomposition 
      Squella Serrano, Juan; Barnafi, E.; Perna, S.; Núñez Vergara, Luis (1989)
      A method for the differential-pulse polarographic determination of nifedipine has been developed, based on the electrochemistry of the aromatic nitro group in the drug. Polarography has also been used in studies of the ...
