5. Conclusion
This work presents a valuable contribution to analytical chemistry
field as well as those related disciplines including pharmacology,
biochemistry and medicine, principally. A new applicationof the CPE for the analysis of ARV in human plasma by UFLC-MS/MS
was proposed for direct application in real studies. The CPE-UFLCMS/
MS was developed on real matrices, which allowed a comprehensive
characterization and optimization of the procedure with a
feasible validation according to international standards. The proposed
analytical methodology was developed and applied for
analyzing of ABC, EFV, 3 TC and NFV in human plasma. Under
optimized working conditions the proposed analytical methodology
meets standards requirements of international guidelines,
which makes it suitable for pharmacokinetic studies of four ARV, as
well as for therapeutic monitoring of HIV patients. Additionally to
its analytical performance, it is important to point out that the
proposed sample preparation technique has an environmentally
friendly character that makes it suitable for current green chemistry
trends.
