Introduction: A UV-spectrophotometric method has been developed for the quantitative estimation of fluconazole. The present study describes development and validation of UV-spectroscopic method for estimation of fluconazole reference substance and validation of detection method. Method: During development of analytical method HCl: water (6 different concentrations). The detection length (cmax) was found to be 260nm. Calibration curves were prepared. The proposed method obeys Beer’s law in the range of 5-50mkg/ml. Absorption maxima was determined with 10 mkg/ml by scanning in the range of 200-400nm. Results: Percent recovery studies are in the range of 95,12%-101.89%. The method was validated in terms of specificity, linearity, accuracy, range, precision, repeatability, robustness, stability of analytical solution. Results of analysis were validated statistically and by specificity studies. From that it was observed that there is no interference of blank, excipients during the estimation of reference substance in formulation. Conclusion: This shows the adaptability of the method for routine estimation of fluconazole reference. Keywords: Fluconazole, method development, validation, spectrophotometry

Problem: As of November 2022, over 417 397 confirmed cases and 2631 deaths related to coronavirus disease (COVID-19) were reported in Pacific island countries and areas (PICs). Most PICs have faced challenges accessing therapeutics recommended for the treatment of COVID-19 due to their high demand worldwide and supply chain constraints. Context: The World Health Organization (WHO) coordinates and provides tailored technical and operational support to 21 PICs. Since the start of the pandemic, WHO has worked with partners to establish a mechanism to ensure equitable access to three novel COVID-19 therapeutics (tocilizumab, molnupiravir and nirmatrelvir/ritonavir) for lower-income countries, including 11 eligible PICs. Action: WHO coordinated the requests, procurement and distribution of the three novel therapeutics. In addition, WHO supported PICs by providing trainings in clinical management of COVID-19, developing critical supply needs estimates, and facilitating regulatory approval of clinical therapeutics, including emergency use authorization. Lessons learned: The main barriers to procurement of novel COVID-19 therapeutics were identified as prolonged negotiations with licence holders, sourcing funding, the high cost of therapeutics and limited capacity to provide safety monitoring. Discussion: Uninterrupted supply and availability of essential medicines in the Pacific region is dependent on external and local sourcing. To overcome procurement barriers and ensure access to novel COVID-19 therapeutics in PICs, WHO‘s pandemic support to Member States focused on strengthening regulatory requirements, safety monitoring and supply chain activities.
