Abstract

Clindamycin (CLIN), an antibiotic sold in the form of capsules, injectable solution, gel, and lotion, is easily soluble in water and ethanol. However, it lacks eco-efficient methods for evaluating pharmaceutical products. The objective of this review is to provide an overview of the analytical methods present both in the literature and in official compendia for evaluating pharmaceutical matrices based on CLIN in the context of Green Analytical Chemistry (GAC). Firstly, microbiological methods for evaluating the potency of CLIN final products were not found, which already shows the need to develop new methods. Among the methods found, which are all physicalchemical, the most used method is HPLC (71%) followed by UV-vis (14%). Among the targets of the methods, capsules and raw materials were the most studied (33% each). Among the choices of analytical conditions for the methods, acetonitrile is the preferred solvent (27.7%), even though CLIN is easily soluble in ethanol. Thus, the gap in eco-friendly and sustainable analytical methods is a reality and an opportunity for analytical development centers to provide means for evaluating the quality of CLIN-based products.
