β-Adrenergic blockers represent a very important class of drugs that are used worldwide for treating various cardiac diseases. The present article describes the state-of-the art of analyses of β-adrenergic blockers using high-performance liquid chromatography (HPLC). Sample preparation techniques such as liquid-liquid extraction, solid-phase extraction and solid-phase microextraction have been discussed, which are essential prior to HPLC analysis. Additionally, applications of liquid chromatography coupled with tandem mass spectrometry are included. HPLC methods have been reported to include 0.6-26 min as the run times and 0.01 ng/mL to 25 µg/mL as detection limits. The most commonly used columns were C18 with various buffers as the mobile phases, along with various organic modifiers. The optimization of HPLC conditions has been discussed. It has been observed that the reported methods are quite satisfactory for the analyses of β-adrenergic blockers in biological samples. Future perspectives in the hyphenation of solid-phase microextraction-nano-liquid chromatography-tandem mass spectrometry have also been highlighted to achieve detections at nanogram and picogram levels. The present article is very useful for academicians, scientists, drug and pharmaceutical personnel and government regulatory authorities.
