Abstract
Background: Azithromycin (AZT) is an antimicrobial available in different pharmaceutical forms
and many people can have access to this medicine. Therefore, the existence of adequate and reliable analytical
methods for evaluating the quality of AZT and AZT-based products is essential.
Objective/Methods: The purpose of this review is to discuss the analytical methods for evaluating AZT present
in the literature and official compendia in the context of Green Analytical Chemistry (GAC).
Results: Among the methods found in the literature for evaluating AZT, the most used method is HPLC (62%)
followed by TLC (14%) and the microbiological method by agar diffusion (14%). Even pharmacopoeias recommend
the analysis of AZT by HPLC or agar diffusion. Acetonitrile and methanol account for 35% of the
most used solvents in the analyses, followed by buffer.
Conclusion: AZT lacks analytical methods in the context of GAC. Both physical-chemical and microbiological
methods can contemplate the environmentally friendly way to analyze AZT and AZT-based products, depending
only on the chosen conditions. Ethanol, purified water, acetic acid instead of methanol, acetonitrile,
buffer, formic acid in the physical-chemical methods are excellent alternatives. However, in the microbiological
method, turbidimetry is a great option instead of agar diffusion.
