Use of Differential Spectrophotometry for Determination of Cytarabine and Acyclovir in Their Dosage Forms

Derivative spectrophotometric method for determination of acyclovir in polymeric nanoparticles

“…Several applications have been found in many areas of analysis, especially in pharmaceutical. [19][20][21] Some methods employing DS were reported to the quantification of acyclovir (9-[2-hydroxyethoxymethyl]-9H-guanine, ACV) ( Figure 1) in order to quantify this drug in pharmaceutical dosage forms, such as injections and creams 22 or in the presence of guanine, its main impurity. 23 Nevertheless, according to our knowledge, there are no reports concerning the quantification of ACV in PACA nanoparticles by this technique.…”

LC methods for acyclovir and related impurities determination

“…A visible spectrophotometric method, not very sensitive [2], a derivative spectrophotometric [3] and a differential spectrophotometric method [4] have been proposed.…”

Osteryoung square wave stripping voltammetry at mercury film electrode for monitoring ultra trace levels of Tarabine PFS and its interaction with ssDNA

“…Several analytical methods for the determination of Tarabine PFS have been reported including UVspectrophotometry and polarography [8][9][10][11][12], derivative spectroscopy [13,14], gas chromatography [15], high performance liquid chromatography (HPLC) [16][17][18][19][20][21][22] and capillary electrophoresis techniques [23]. Also, Tarabine PFS and other pyrimidine derivatives have been detected by radio-enzymes [24], radioimmunological [25] and microbiological methods of analysis [26,27].…”
